What was the name of the man who discovered Neptune with his telescope in 1846?

1 Galileo Galilei
2 William Herschel
3 Johann Galle
4 Edmond Halley


:hmm:

[Radar]

I'm thinking William Herschel? Only because I've seen doco's on the others and never heard of them being credited with the find. :pipethinker:

[Draig]

William Herschel.

Cheers Colin

[Astro Dave]

Now, what was it about Uranus that made them go looking for Neptune?

[Draig]

Mmmmm..:hmm:

Wasn't a slight "wobble" in Uranus' Orbit?

Cheers Colin

[phoenix]

The answer is
Johann Galle discovered Neptune in 1846, the second planet (after Uranus) to be discovered using a telescope.




Cheers Jason :pipethinker:

[Draig]

Bugger wrong again :Chessy_Smile:

Well done Jason on that spot quiz.

Cheers Colin

[Astro Dave]

Col, it was a slight wobble in the orbit of Uranus that made them start looking for the cause.

Now, Col, I think you'd agree, if you had a slight wobble in Uranus you'd like someone to politely 'take a look at it' too - wouldn't you?

BTW - This was a planet that was the first to be discovered mathematically before it was actually seen!!!

[phoenix]

Q: Describe Uranus.

1 A Large and very far from Earth, it is grouped with the giant planets. A bluish-green color. Not even the strongest of telescopes can detect any surface feature.

2 A Large terrestrial planet with a pinkish glow. Many surface features were studied by the early astronomers.

3 That would be a rather personal question, don't you think?


:hmm:

[wakaleo]

Hahahaha! But 1 is correct.

[phoenix]

wakaleo. :welldone:


OK


What was the first year that australian scientists tracked an american satellite by radio?

:hmm:

[Draig]

Mmmmm..... :hmm:

I'd have to geuss here and say 1966.

Cheers Colin

[wakaleo]

My guess is the same as Draig's - 1966. Was it Tidbinbilla?

[phoenix]

Sorry guys nice try it was 1958. Woomera scientist tracked americas first ever satellite, explorer 1, In january 1958.


The colour of light is dependent on what ?

In which NSW town would you find Australia's largest sun dial ?

1 Jindabyne

2 Inverell

3 Singleton

4 Sydney

[Draig]

The immediate question to this is why????

But I suppose the World's Largest "fill this spot with whatever you feel like" has to be somewhere in Australia.

Mmmm... I guess number 3.. Singleton?

Cheers Colin

[wakaleo]

I'll go with Colin and say Singleton. In fact I'll go so far as to say it's the largest sundial in the Southern Hemisphere. (Aust. Geographic Apr-Jun 07, p10)

[Radar]

Sydney? I'm thinking its one of the towers there. :hmm:

[phoenix]

Welldone Colin & wakaleo :thumbsupmate:


The bicentennial gift to singleton is 14.7m across with a height of nearly 8m.



What instrument is used to measure the amount of moisture in the atmosphere?

1 Hygrometer

2 Humidiscope

3 Theodolyte

[Draig]

Hi Phoenix,

Say this is almost starting to be fun...... must be illegal.

I even know the answer to this one it's a Hygrometer.

CHeers Colin

[phoenix]

Hi Phoenix,

Say this is almost starting to be fun...... must be illegal.

I even know the answer to this one it's a Hygrometer.

CHeers Colin


Colin i would have to say you are correct :thumbsupmate:

Hydrometers measure the relative humity of the air, as a percentage of how much can hold at a given temperature.


ok then

Who was the first australian to be a full-time member of the NASA astronaut corps ?


1 Mike colins

2 Andy thomas

3 Charles ulm

4 Alan shepard

[Draig]

Lets see now -

Alan Shepard and Mike Collins were both part of the orginal NASA corp (Sorry I just finished watching the "Right Stuff").

Charles Ulm (if I rember my boring school years correctly) had something to do with Charles Kingsford-Smith.

So that only leaves Andy Thomas - South Australian if I remeber correctly.

Cheers Colin

[Astro Dave]

God boy Jason for coming up with this little side-line. Sure beats the heck out of some individuals berating the heck out of others.

Now, C'n I have go???? I love quizzez, OK... let's see ... I fink it might be the lost and forgotten Aussie with oodles of 'Derring Do' Paul Scully-Power. He was Australia's first astronaut and was on the space shuttle 'Challenger' back in 1984.

This is what I fink. Do I win summink?

[phoenix]

Sorry Dave the answer was ........Andy Thomas
Dr Andy Thomas has flown several missions and spent time in the russian space station mir.

You win Colin :welldone:

[QUOTE=phoenix]Sorry Dave the answer was ........Andy Thomas
Dr Andy Thomas has flown several missions and spent time in the russian space station mir.


Errr, Jason - just check your facts on this one good buddy.

Paul Scully-Power is an oceanographer and was a NASA Payload Specialist He became a U.S, citizen in 1982.

In June 1984 he was chosen by NASA to be a member of the 13th Shuttle mission, which would study Earth Sciences. His space flight experience include STS-41-G Challenger - October 5-13, 1984. STS-41-G was the first mission with a 7-person crew.

At mission conclusion, Scully-Power had logged over 197 hours in space.

There was another before him though.

Dr. Philip Kenyon Chapman was the first Australian-born American astronaut, serving for about five years in NASA Astronaut Group 6 (1967).

After gaining U.S. citizenship, Chapman was selected as a scientist-astronaut by NASA in August 1967. He trained as an astronaut, including jet pilot training with the USAF, and served as the Apollo 14 Mission Scientist.

He resigned from the program near the close of the Apollo Program in July 1972, largely because he strongly disagreed with the decision to build the Space Shuttle.

[phoenix]

You are right about Paul Scully-Power being the first australian astronaut Dave :yesplease:


But Andy Thomas became the first fulltime astronaut


Who was the first australian to be a full-time member of the NASA astronaut corps.

In electricity, What does AC stand for?

1 Advanced circuit

2 Alternating current

3 Aluminium circuit

4 Aggregate current

[Draig]

Hi Phoenix,

AC = Alternating Current

Cheers Colin

[phoenix]

Colin :welldone:

DC(direct current) Had been in use for some time, But nikola tesla discovered that alternating the current was a more effective way of providing electrical power.


What did the CSIRO use to seed clouds in their rainmaking experiments of the 1940s ?

1 Fine silica powder

2 Dry ice

3 Sulphur dioxide

4 wood fibre

[Mick]

Dry ice, delivered by the RAAF.

[wakaleo]

I'll go with dry ice too!

I have a question for you all. If you took all the bones out of your feet and laid them end to end:
1) it might hurt a bit.
2) you wouldn't be able to dance any more.
3) What! are you mad?
4) All the above.

[phoenix]

Mick & wakaleo :welldone:

Dry ice crystals, and later silver iodide, were used to seed clouds with mild success.


The answer to your question wakaleo would be,
All of the above. lol

Cheers Jason :pipethinker:

[phoenix]

Which Astronomer was best known for his theory that the earth resolves around the sun?

1 Edmund Halley

2 Johannes Kepler

3 Galileo

4 Nicolaus Copernicus

[Radar]

Galileo and Copernicus both gained notoriety out of this concept, so it could be either. Though Galileo was put on home detention and almost sentenced to death for his voice.

[Draig]

Hi All,

It twas Copernicus. Galileo was sentenced to house arrest by the Inquisition for his support of Copernicus and writing is book entitled Dialogue Concerning the Two Chief World Systems.

Strangely enough he wasn't fully "forgiven" until 1992.

Cheers Colin

[Mick]

Yes i agree, Nic Copernicus :pipethinker:

[phoenix]

Yes guys the answer was Copernicus :welldone:


What causes fluorescent materials-like your watch hands-to give off light ?

[Noel Carboni]

Q: Describe Uranus.

1 A Large and very far from Earth, it is grouped with the giant planets. A bluish-green color. Not even the strongest of telescopes can detect any surface feature.


1 is the answer; well somewhat, it's not quite right as worded. THE strongest telescope - the Hubble Space Telescope - indeed has shown surface features, in addition to rings. Check these out:

http://www.spacetelescope.org/bin/images.pl?searchtype=freesearch&string=uranus

Now, if you were the one who discovered rings around Uranus you might have something to talk about with your doctor who's into asstronomy. :yesplease:

1 Caribbean sea

2 South china sea

3 Tropical Australia

4 India and bay of bengal

5 Bass strait

[Draig]

Hi Phoenix,

Now most people would be tempted to say Tropical Australia - or fot those who live there Northern Queensland, Northertn Terrority and Northern Western Australia.

However the real hot spot for Cyclones is the South China Sea.

Cheers Colin

[phoenix]

South China Sea :thumbsupmate:

Cheers Jason :pipethinker:

[wakaleo]

This quiz is a great idea Jason, but sometimes when I log on I find there's been a few questions I've missed and the answers to them have already been posted. How about fixing a time for submission of member's answers before you post the correct answer.

You could make the cut-off time midnight (for instance) after which you post the correct answers along with a new question. This would help to spin the quiz out a bit and allow more members a chance to answer (even if it means they google it or check it out on wikipedia. It's all learning!).

Cheers Colin

[Robert TG]

On the fifth day of the mission, Astronauts Thomas P. Stafford and Eugene A. Cernan descended in the lunar module to an altitude of less than 47,000 feet (14,326 meters) above the Moon. At this altitude, two passes were made over the future Apollo 11 landing site. The LM then completed a successful rendezvous with Astronaut John W. Young in the command module.

The answer was WA

The 11.5 tonne iron meteorite was found on the Nullarbor plain and can be seen in the WA museum.




629




Between 1911 and 1918 the first three pieces were discovered, but the two main masses, two fragments that fit together, weren't until 1966. Apparently the weight of these masses has so far been estimated only, for the references given range between 10t to 16t for the larger and 4t to 6.1t for the smaller one. The larger fragment is in Perth, the smaller one was taken to Heidelberg, sliced up and distributed.



Heres a link where it was found http://en.wikipedia.org/wiki/Nullarbor

I'd reckon you'd be close Radar, over the distances the impulses have to travel (less far in some heads than in others!), but resistance would still have some effect. I'd guess thought would travel marginally less than the speed of light, but not significantly (or maybe even measurably).

Then again, sometimes my thoughts feel like they're travelling through quicksand!

[Draig]

A man is lying dead, face down in the desert. There's a match near his outstretched hand


Solution ?

[Astro Dave]

Err, Ahh..Err C'n I have a go Pleeeze?? ("throw it to me, throw it to me!")

He was with several others in a hot air balloon, crossing the desert. The balloon was punctured, and they began to lose altitude. They tossed all their non-essentials overboard and then their clothing and food, but they were still sinking too fast. They drew matches to see who would jump over the side and save the others. This man lost... big-time.

This is a good one.. think laterally.

Q/ Joe wants to go home but can't, because the man in the mask is waiting for him. ???

[Robert TG]

Joe wants to go home but can't, because the man in the mask is waiting for him. ???

Joe is being born. He can never return to the womb and the doctor is delivering him.


But I am trying to think of an astronomical twist to this. LOL

[Radar]

Q/ Joe wants to go home but can't, because the man in the mask is waiting for him. ???

Joe is an armed robber. They are robbing a telescope shop of all their new APO's, and the man in the mask is the getaway driver waiting out front. Half way through the robbery, Joe realises that the APO's are heavier than he first thought, and wished he was home, but can't because the man in the mask is waiting for him out front and wants his 'cut'. :Chessy_Smile:

As a man jumps out of a window, he hears the telephone ring and regrets having jumped.

Why?

[wakaleo]

He was told he'd get a call from his doctor by a certain time to tell him that he didn't have a terminal disease, and when it didn't come he jumped, just seconds too soon! ?

[Astro Dave]

Well done Jason young chasp right you are wiv der answer.... seems I've found your page, and so have others.

[Astro Dave]

Now , this speed of thought thing. Let me rephrase the question.

What I meant was , if telepathy works, then how fast is the 'message' sent to the recipient travelling?

In other words, how fast do thought waves move? By the way, it isn't a trick question because I haven't got a bloody clue about the answer.

[Draig]

Hi there young Dave,

this might help your speed problem.

[Robert TG]

Pseudoscience.

"if telepathy works"

There is no proof that it does. All the evidence has turned up con men or failure.

My understanding of how the brain works is that there are chemical reactions that create small charges, which the brain then interprets into thoughts. There is no broadcast antenna transmitting brain waves. No one can ‘pick up’ the signal because there is no signal.


“ ‘Telepathy’ literally means to feel at a distance, just as ‘telephone’ is to hear at a distance and ‘television’ is to see at a distance. The word suggests the communication not of thoughts but of feelings, emotions….
...People who know each other very well, who live together, who are practiced in one another’s feeling tones, associations and thinking styles can offer anticipate what the partner will say. This is merely the usual five senses plus human empathy, sensitivity and intelligence in operation. It may feel extrasensory, but it’s not at all what’s intended by the word ‘telepathy’….
...It is barely possible that a few of these paranormal claims might one day be verified by solid scientific data, but it would be foolish to accept any of them without adequate evidence.”

Quote from “The Demon-Haunted World”. Read the book! see details below

[Robert TG]

The speed of thought problem can also be looked at a different way.

I 'imagine' myself a light years away. In my mind I'm there instantly. I could jump to 10 billion light years in a flash.

[phoenix]

That was a good answer wakaleo,
The answer i have is......................This is a post-holocaust scenario of some kind; for whatever reason, the man believes himself to be the last human on Earth. He doesn't want to live by himself, so he jumps -- but when he hears the telephone ring, he realizes he's not the last human on Earth after all.

Number 4 (with help from number 5 of course!) ;-)

[Radar]

Click here for a clue (http://www.wavcentral.com/sounds/movies/contact/confirmed.mp3)

:hmm:

[Draig]

Hi All,

Karl Jansky

(sorry cann't blame Dave for this).

Cheers Colin

[phoenix]

The answer was Karl Jansk :welldone:

Karl Jansk, The basic unit of radio brightness, the Jansky (Jy), is named after him.

[phoenix]

The famous Perseid meteor shower is well known. A lesser known fact is the comet it orginates from. What is the parent comet of the Perseids?

1 Encke

2 1862III (Swift-Tuttle)

3 Halley

4 3200 Phaeton

[Radar]

Hmm, this is a hard one. What comet has moved through Perseus?

[phoenix]

The answer was 1862III (Swift-Tuttle)

[phoenix]

A giant system of stars would be defined as a what?

1 A novar

2 A pulsar

3 None of these

4 A quasar

[Medusa]

A pulsar ?

Medusa

[Radar]

A novar, pulsar and quasar are all types of stars, so I choose option 3.

[phoenix]

You are correct Ray,

None of these
There are literally millions of known galaxies in the universe. We live in the spiral-shaped Milky Way galaxy, on the end of one of the 'arms'.

[phoenix]

When matter spins toward a black hole, what kind of energy does it release?

1 Gamma rays

2 Ultraviolet rays

3 Infrared light

4 X-ray energy


............................................:hmm:

[Robert TG]

all ot the above

[phoenix]

Hey Robert.


I thought it was only Xray energy ?

[phoenix]

Which constellation has the star Sirius in it?

1 Ursa Major

2 Gemini

3 Orion

4 Canis Major

[Noel Carboni]

Hey, one I know without looking anything up. Answer 4, Canis Major (the Big Dog) is of course the home of Sirius, the Dog Star, also known as Alpha Canis Major.

Here's one:

How long does it take Venus to complete one orbit about the Sun (i.e., its sidereal period)?

1 - 583.9 days.

2 - 1 year.

3 - 224.6 days.

4 - Once in a lifetime.

-Noel

[Radar]

I'd choose option three here, purely because Venus has a smaller orbit. :hmm:

[Noel Carboni]

And you would be correct. :)

-Noel

[Robert TG]

Which one of these is NOT a moon of Pluto? And what is it a moon of?

a. Charon
b. Daphnis
c. Hydra
d. Nix

[Cosmic_Rider]

Howdy

I know the moons of pluto are, Charon, Hydra and Nix, so the answer is Daphnis, so do i get half a point?


Regards
Peter

[Radar]

Because Jupiter has so many moons, I'd say that Daphnis is a Jovian moon. :hmm:

[phoenix]

Daphnis is the moon of saturn or uranus. :hmm:








Cheers Jason :pipethinker:

[Robert TG]

Cosmic Rider, You get a FULL point for the correct answer of 'Daphnis'


Daphnis is not a moon of Pluto or Jupiter.

Which leaves Phonix's answer of either Saturn or Uranus partly correct. So I'd give a 1/4 point for that.

Daphnis is a moon of Saturn. It is 6-8km in diameter.


Just a real question here, not part of a Quiz as I don't know the answer. How small can an object get and still be called a moon? There are many 'moons' around the 2km diameter mark, so how about ones smaller. Will they change the definition of a moon to include a new term 'Dwarf Moons' as they have with planets? At what size do they distinguish between the 'rubble' of saturn rings and small moonlets?

[phoenix]

A telescope's resolving power measures its ability to see

1 fainter sources. east

2 more distant sources

3 finer details in sources

4 larger sources

5 more rapidly moving sources

[AstroTasmania]

Resolve finer detail, number 3.

Shevill

[Draig]

HI All,

Number 3, Finer details from the source.

Colin

[phoenix]

Hi Shevill & Colin, You are both correct. :thumbsupmate:

Heres Another




A ground-based telescope to observe x-rays would

1 be a powerful tool for studying abnormally cold stars or distant planets.

2 give astronomers the chance to study the insides of stars and planets.

3 be worthless because no astronomical objects emit x-rays.

4 be worthless because x-rays can not pass through the Earth's atmosphere.

5 be worthless because astronomers have not yet devised detectors for x-rays.



Cheers Jason :pipethinker:

[Draig]

Hi Jason,

I could be wrong on this but I think it is number

4 be worthless because x-rays can not pass through the Earth's atmosphere.

Cheers Colin

[AstroTasmania]

Number 4 it is, X-rays (fortunately) are absorbed by our protective atmoshere.

Clear skies... Shevill

[phoenix]

Colin & Shevill you are both correct again. :welldone:


Heres Another



One way to increase the resolving power of a telescope is to

1 make its mirror bigger.

2 make its mirror smaller.

3 replace its mirror with a lens of the same diameter.

4 use a mirror made of gold.

5 observe objects using longer wavelengths..

[AstroTasmania]

No 1 it is. Make a larger mirror/optic,

Clear skies...Shevill

[Draig]

I agree with Shevell.

Number 1 - larger mirror.

Cheers Colin

[phoenix]

Shevill & Colin you are rrrrrrrright again.:welldone:




What is the most important thing to consider when choosing a telescope?

1 brand

2 size

3 aperture

4 power

..............:hmm:

[Medusa]

Well that would depend on how much money you have to spend, Im guessing aperture would be one of the first things to look for when purchasing a scope, So i will say (3) aperture

Medusa

[Draig]

Hi All,

I'll agree with Medusa and say Aperture.

Cheers Colin

[phoenix]

Colin & Medusa you are both correct.:yesplease:



Although the biggest telescope may seem to be the best bet, don't bet on it. Aperture refers to a telescopes main optical lens or mirror. This relates directly to the light gathering power, and maximum resolving power of a telescope.



The magnification of the object is dependent largely on the ____ ?

1 eye-piece

2 the thickness of the mirror

3 size of the scope

4 the primary mirror

[Draig]

HI All,

I'll say Eyepiece, because all we are really magnifing is the image in the mirror.


Cheers colin

[phoenix]

Your right colin its the eye-piece. :welldone:

Although the size of the scope does matter, the most important factor is the magnification of the eye-piece.



What type of telescope uses both lenses and mirrors to magnify the image?

1 reflecting

2 double telescope

3 refracting

4 catadioptric system

[Draig]

HI All,

Number 4. A catadioptric system.

But you just try saying that word when you drunk. :Chessy_Smile:

Cheers Colin

[Radar]

What?

I always thought a catadioptric was something magicians did with a pack of cards and a feline. :hmm:

:duh:

[phoenix]

Your right Colin its a catadioptric system

In the 1930s, another type of telescope was put to use at some observatories. Using both mirrors and lenses, this telescope can make the image clearer.

The biggest asteroid to hit the Earth in the 20th century struck on what continent?

1 Asia

2 North America

3 Australia

4 Africa

[Draig]

At a guess I'd say Africa.

I seem to remeber a story of a Roman Catholic Priest who wintessed the event.

However there is also the one that flattened the forrest in Siberia in the 1920's (I think that was when it was anyway), but you don't seem to have an option for Russia, and I don't think Siberia is part of Europe or Asia.

Cheers Colin

[phoenix]

The correct answer was Asia.

The asteroid, which weighed 100,000 tons and was the size of a large house, exploded over Siberia (located in Russia) on June 30, 1908. The asteroid burst apart four miles above the ground and demolished acres of forest by the thousands. The force of the impact is said to have been 2,000 times stronger than that of the atomic bomb. The biggest asteroid ever to hit Earth in the whole of the planet's existence however is unknown, as scientists believe it happened millions of years ago, causing the extinction of 90% of the species from the sea, and 70% of the species on land.

[phoenix]

Light cannot escape from a black hole once it crosses which of the following?

1 the Flutzenhouser diameter

2 the Hallenburg point

3 the Schwarzschild radius

4 the perpendicular angle of a black hole

[Medusa]

The Schwarzschild radius ?

Medusa

[phoenix]

Yes Medusa, The correct answer is the Schwarzschild radius.

A black hole is the endpoint of a massive star. When a star has a mass greater than 10 to 15 times of the sun's, it leaves behind a gigantic space of darkness. While it is believed that objects such as stars, moons, planets, comets, and asteroids are sucked into a black hole, this is not exactly accurate. A black hole is a star that has reached its end, and has collapsed into it, creating an infinite amount of density and zero volume. Because of this, light that travels through a black hole and passes it's Schwarzschild radius will never be able to escape.

[phoenix]

Which planet has winds that reach speeds of 1,100 miles per hour at its equator?

1 Saturn

2 Mercury

3 Jupiter

4 Uranus

.................................................. .:hmm:

[Draig]

HI All,

Saturn used to have wind speeds of 1700km/h at the equator. But they have recently been reported as slowing down. So I'll say Saturn.

(I think Jupiter has winds of only 400mph)

Cheers Colin

[phoenix]

Your right Colin its saturn :welldone:

Saturn is the second largest planet in our solar system, after its neighbor, Jupiter. It has the least amount of density of all the planets (about 30% less dense than water). This leads people to believe that if a body of water larger than the planet was found, Saturn would float in it. Considering the vastness of space, a body of water that size could possibly exist somewhere in one of the many galaxies we know of. Saturn's day is less than half as long as an Earth day, lasting only 10 hours and 39 minutes. Saturn's orbit around the sun takes 29 1/2 Earth years.

[phoenix]

Which of Mars' moons orbits the red planet three times in a single day (or once every seven hours)? .............................:hmm:

[Robert TG]

Phobos.

It is said that Mars moon's are actually captured asteroids, being that they are very small. Deimos is said to be between only 6 to 8 km in Radius (not being round), compare that to Our Moon which is 1,738 km in Radius.

There are about 26 asteroids over 100km in radius, so these moons of Mars are quite small even by asteroid standards.

[phoenix]

You are correct Robert.:welldone: :welldone:


Phobos is a very irregularly shaped moon, as is Mars' second moon, Deimos. Phobos is only 3,000 miles above the surface of Mars. It also takes only seven hours to orbit the planet. Compare that to Earth's moon, which is 238,000 miles away from Earth and orbits the planet approximately once every 28 days.

[phoenix]

Polaris (the North Star) is the Latin abbreviation for what? ...................................:hmm:

[Draig]

HI Jason

How's this?

New Latin (Stçlla) Polâris, polar (star), from Latin polus, pole.

Cheers Colin

[phoenix]

Hey Draig

The answer was Stella Polaris. :thumbsupmate:

Stella Polaris, meaning The Pole Star, has been given many names other than the North Star. It is also known as The Lodestar, The Navigator's Star (or Navigatoria), Phoenice, Angel Stern and many, many more. The North Star is 680 light-years away from the North Pole of the Earth. It is said that the light from Polaris takes approximately 680 years to travel to Earth. This means when a person looks up at Polaris, the twinkling light of the star is actually 680 years old. Polaris is located in the constellation Ursa Minor.

[phoenix]

The atmospheric composition of Neptune is 85% helium.

True or False ...............:hmm:

[Robert TG]

I guess False.

85% seems far too high a level.

There would have to be a larger amounts of Hydrogen than just 15%.

Methane gives the planet it's blue colour, but I believe it's a rather small percentage of it's atmosphere.

[Draig]

Hi Jason,

The answer is false.

Whilst I don't know the exact percantage's only one third of Neptune is made up of Hydrogen, Hellium and Methane.

Cheers Colin

[phoenix]

Robert & Colin well done top of the class.:welldone:

The answer is False
The atmospheric composition of Neptune is as follows: 85% hydrogen, 13% helium, and 2% methane. Neptune is one of the gas giants, along with Jupiter, Saturn, and Uranus. These are also the only four planets that each has rings. Though most people associate Saturn as the ringed-planet, it is true that the other three gas giants have rings as well, though they are much fainter than those of Saturn.


Cheers Jason :pipethinker:

[phoenix]

What is one advantage of a very large Dobsonian telescope?


1 Ease of transporting

2 More light gathering power

3 Lighter weight

4 There is no advantage

[Robert TG]

2. More light gathering power

If I understood the question correctly, as compared to a 'smaller Dobsonian telescope', which by it's very nature of being smaller would be lighter and easier to transport.

"Dobsonian telescope" is refering to the telescopes mount, and if you are comparing the 'mounts' to a similiar size telescope with a different mount than the answer of 1 & 3 would be applicable.

[phoenix]

You are correct Robert:welldone:

More light gathering power allows for fainter objects to be seen.

[phoenix]

What is not a type of telescope mount?

1 Longitudal

2 Equatorial

3 Altazimuth

4 German equatorial

[phoenix]

The answer is Longitudal
There is no such thing as a longitudal telescope mount, at least, I don't think there is!.........................:hmm:

[phoenix]

The biggest refractor (telescope) in the world is at Mount Palomar.


True or False
