Astronomy & Space - May 2007

I've heard that Jupiter radiates 3 times as much energy as it receives from the Sun. This means that the planet has a great internal source of energy. Some astronomers think of Jupiter as a brown dwarf, or a star that failed, because of its small mass. That is, its mass was too small to produce the internal temperatures needed to set off the nuclear reactions that occur inside a star. However, if Jupiter were 100 times bigger that it is now, then it would be a star instead of a planet. Our solar system would have been a binary star system.

I do know that Earth would be bathed with nearly continuous sunlight as the Sun and Jupiter would be on both sides of the planet. But what else things would be if Jupiter were a star? How is that going to effect Earth's life? Would humanity survive as they do in reality, or something else completely different? What would become the rest of our solar system? I think that an alternate Jupiter is a cool sci-fi story that I would write for myself!

ok lets say a MOON-sized asteriod or comet or something came / toward earth ,but it missed it ,and got captured by
earths gravity and and started orbiting earth


*the moon rotates earth in a orbit like saturns ring ,well lets say the rock took a orbit like uranus ring

so wat will happen 2 earth
will we rotate in a different angle or something?

Iridium flares don't damage your eyes. They are mag. -8

Solar eclipses do damage your eyes. Even at 0.1% uncovered. That's magnitude -19

They both have the same surface brightness.

So where is the limit? It must be in between the two.

A the sun has a brightness when viewd from Earth. how much dimmer would the sun appear if you were standing on Jupitor (which is 5 times further from the sun than Earth)? How about if you were looking at the sun from Pluto (which 40 times further from the sun than Earth)?

Help, im stuck I dont get this pleae helps

will it be possible to send people in a beam of light along with all the life support equipment to far of distant galaxies and be reconstituted as reaches its destination from materials at source could the start of life on our own planet have been sent this way either from a dimension or a vast expanse of space.

Did the full moon on the evening of May 3rd affect you or anyone else you know (including animals)? If so, what happened? My 1 1/2 year old cat was zipping around the place like he had a rocket up his butt, and my dog was sitting in one spot and whining for no reason. Now, let's hear your stories.

a) Describe the structure of the Milky Way. (Be sure to describe both the top and side views.) Explain the location of all the main parts and give approximate dimensions. Explain the location of the Sun. What type of galaxy (according to the Hubble Classification scheme) is the Milky Way?


b) Explain how we know the location and distance to the center of the galaxy. Where do we believe the is the center of the galaxy? What do we believe is at the center of the galaxy?

c) How can we map out gas and dust arms in the galaxy?

I have always wondered about that. does it have to do with the height of the flight ? Type of plane ?

Hi,

I have been looking at telecopes for some while now.
I have now narrowed my choise down to two telecopes within my £250 budget.

They are both 6" Celestron reflectors, although one is a Dobsonian, and the other is a more regular one on an equatorial mount.

I would like to know which one would be best for me, if i were to probably use them at home, and move them around fairly often... I would look at the planets, star clusters, and nebulars.

Here are the two 'scopes:

Here is one:

And this is the Dobsionan:

Please say which is better, and why.

Thank You.
