Can you see stars when you are in space?

Of course you can. Just punch into google "hubble telescope pictures" and you will get a lot of photos of stars from space. Some of them are really great.

cheers,
Brendan

Not if you forget to wear a space suit!

Do stars twinkle when observed from outside the earth's atmosphere? No.

Cool, that's what I was wondering. I always assumed the twinkling was an atmospheric phenomena. I guess the "seeing" part should be re-phrased, what do they look like. Just little specks, I assume.

An observant question that is best answered by the fact that stars are light-years away from the earth and from each other. About 30,000 miles out into space does nothing to diminish the quadrillions of miles that separate the stars from each other. It is an interesting, (and mind-boggling) question, though. Sort of like a "If a tree falls down in the forest, do we know who cut it down?" kinda question.

If that's true, then why isn't the sky bright white from all of those trillion stars just in the Andromeda galaxy alone? Something out there in the great interstellar spaces does indeed diminish the starlight that we see.

Stars don't twinkle. Planets twinkle. This is caused by the reflection of the sun on the planet and the reaction of the earth's atmosphere. But this doesn't happen in space.

How did I know that?

One of the better quotes I've seen on tubenet.

I should not post on the ol' TubeNet after a long day at work and a few beers at home...

On the contrary, you should! It makes things so much more fun for all...

In fact, have another!

The expansion of the universe has funny effects on us all.

God spoke of the expanding universe before any scientist figured it out...

Isaiah 40:21 Have you not known?
Have you not heard?
Has it not been told you from the beginning?
Have you not understood from the foundations of the earth?
22 It is He who sits above the circle of the earth,
And its inhabitants are like grasshoppers,
Who stretches out the heavens like a curtain,
And spreads them out like a tent to dwell in.

That's not the case. Stars DO twinkle when viewed from the Earth's surface, and planets *usually* do not. I have observed this on many occasions trying to find Jupiter, Saturn, and Mars in a telescope. Planets definitely do not twinkle.

Forgive me, but I was being pedantic and trying to show how a simple statement such as "nothing gets in the way" can lead to some very profound and fundamental questions about where we live.

I'll go back to my usual insanity...
