And can moons have things orbiting them like smaller moons. If so is there any observations of this. Also if a planet has multiple moons do they ever collide or will collide in the future based on speed differences and paths of a possible future collision.

Yes I know that there will be people out there there who will quote Einstein and say that to travel at the speed of light you will need an infinate ammount of power. But...is it possible? or more to the point is it feasable?

Since the Columbia disaster NASA has spent a large amount of mission time surveying for tile damage. It appears now they’ve got a big ding.

My question is why do they use foam insulation? My lab typically stores these cryogenic fluids, and we do not use foam insulation for the storage and holding vessels. Our dewar has two walls and a vacuum between the layers. I’ve never seen any ice forming on my dewar, and the fluid lasts for days. Why don’t they use a double-walled evacuated external fuel tank?

The spin of the Earth tends to pull us away from the surface but gravity is stronger. How much faster would the Earth have to spin to weigh 100 lb?

How is it that prior to the big bang there was 'nothing', but somehow some atom or something exploded and caused the big bang (or something). So, how was there an atom or neutron or whatever if there was 'nothing'? what is the definition of 'nothing' in this context?

We're looking to get outside San Jose to watch the Perseids, but not so far as to be prohibitive. Any good ideas on places to go?

I've heard things about the "moon" had something to do with the "ocean" or something. But I never understood what is the correlation between the moon and the ocean.

I own one of each. I know how they're different. I am looking for good illustrations to show how they're different on the inside. I will be teaching a bunch of Cub Scouts all about telescopes, the Solar System, and other Astronomy topics. I will show them my reflecting and refracting telescopes, but I'm looking for diagrams to show the internal components, as well.

I looked at the Orion site. They show many examples, but they're external photos. I want to see internal photos, diagrams, illustrations, etc. I'm looking for images that I can download, enlarge and print.

Thank you for providing links.

It is hard to belive that space goes on forever. Is space like a giant sphere that just shot and gre in all directons? Is There an edge to space? Is the universe jjust like and atom or a particle of a GIANT world? Is the universe just a dream? Are we just like rats in a maze?

Basically I received an e-mail from some co- workers. I don't know if it's true or not but it sounds interesting. But I don't want to be outside just standing arounding with my head to the sky and nothing happens. They stated that Mars will be the brightest star starting in August.It will end on Aug. 27th when Mars will actually be visible about 34.65 miles away from Earth.It will appear we have two moons. The next time this may appear is year 2287. Fact or Fiction?

Do you ever think if there are intelligent beings 50 million light years away talking, thinking, and having similar thoughts such as we have? earth seems so insignificant compared to our galaxy.

like when there is a space flight or something and you see the actors all floating around? I know that one way to do this is to get into really high altitude and then let the plane free fall for a while but that wouldnt get you much time to film. are there any other ways?
