Outer space projection?
482626
It is theoretically possible, but very, very, very difficult!\nL2 is roughly 1,500,00 km (or a million miles) from the earth, on the far side from the sun.  So when the moon is on the sun side of the earth, with it's dark face toward the earth (a new moon), the distance from the L2 point to the moon would be 1.5M km (to earth), plus 375,000 km  (to the moon), then bounce back to earth, for a total of 2.25 million km (or 1.5M miles).  Since the moon only reflects about 1/10 of the light that hits it (its albedo is .12), the light source at L2 would have to be 10 times as powerful as if you were reflecting off a mirror (or 6-8 times what it would be off a good screen).\n So let's figure how powerful that light would have to be.  Let's say that you want to just barely be able to see this projection, say, about as well as you could see a candle on a perfectly dark night at a distance of a kilometer. Well, light power varies inversely as the square of the distance.  So (simplifying a lot to just get a rough idea) that light would have to be 2.25M, squared, times 10 (for the moon's reflectivity) candlepower to hit your eye with that same power.  So you'd need a light of 50,625,000,000,000,000,000 candlepower.  By one account, the most powerful light currently existing on earth is about 1,000,000,000 (one billion) candlepower.  \n I've simplified quite a bit; you could reduce the power requirements many orders of magnitude by focusing the beam or using a laser, but the answer still comes out to be that you'd need a light millions of times more powerful than the brightest lighthouse.  And you'll need thousands of square kilometers of solar cells to power this super projector.  And thousands of rockets to get all this equipment out to L2!\n\n So to answer your question - is it THEORETICALLY possible?  Sure!  But there is a huge world of difference between theory and practical application on this one!

Outer space extends to the end of the universe. Further, the universe is constantly expanding. No-one knows if anything is beyond the end of the universe.

The scientist in charge of this project were taking extra care with picture preparation. Go to the site and you will see that around May 17th I think we can start looking for the particles from space.\nSee link below for Stardust at Home

It might be Seti@Home...\nIt's to look for extra terrestrials...\nhttp://setiathome.berkeley.edu/

Hi. This is how NASA does it : http://science.nasa.gov/headlines/y2000/ast02nov_1.htm

The answer involves a wormhole in the space time continuum and a secrete plot by sock manufactures.  I could explain it better, but I'd need an overhead projector and a white board.  :P

Easy. The SETI program. Search for Extra-Terrestial Intelligence. Check out their website. It's an array of dishes set up to monitor certain types of signals that might be ET in origin. If I'm not mistaken, they've broadcasted in the past too.

there is no direction in outer space.. thers is no up and no down.. we have this kind directin because of gravity.. our geographic north is the magnetic south and vice versa..

where ?\nin outer space. there is room enough.\nor am I wrong ?

Well, it was either aliens, or a governemt piece. According to sources, we've been been working on an interstellar drive since just after WWII. Take your choice. Either way, you and I will never get to ride it.

Try www.nasa.gov, or do a Google image search for space, planet, etc.

Is there such a thing as close by planets?\nWith all that we see in the night sky, not just stars but galaxies as well, what are the chances that we are alone in the universe?\nThere has to be intelligent life out there. We are all just too far from reach of each other. And most likely, other intelligence would be like us and send probes. Living beings could not survive the long travel, space probes could.

In outer space...       ... about 6 inches away from Uranus

They make those. Maybe try http://www.skyandtelescope.com \nOr you could take a regular globe mark some 300odd major stars in position with the aid of a star catalog (glowinthedarkpaint?) and then paint the rest black. Everything'd be backwards unless you could stick your head inside (?) Meow.

I suppose it would be possible in theory. You would need an insanely bright source to project anything easily visible from Earth though. Why would you even want to do that?
