dbzzx Posted February 24, 2006 Share Posted February 24, 2006 I was wondering what the difference is between land and space based telescopes. What makes them different from eachother?? Link to comment Share on other sites More sharing options...
Sisyphus Posted February 24, 2006 Share Posted February 24, 2006 The principles behind them are the same, but there are advantages to each. Land-based telescopes are bigger, cheaper, and easier to maintain, for obvious reasons. Space-based telescopes, however, have the huge advantage of not having to look through the Earth's atmosphere, meaning they can get much clearer pictures and much less interference.

dbzzx Posted February 24, 2006 Author Share Posted February 24, 2006 Thats the only difference? Cant they see more into the galaxy like the hubble can see more into the galaxy then land based ones right? Link to comment Share on other sites More sharing options...
Cap'n Refsmmat Posted February 24, 2006 Share Posted February 24, 2006 Indeed. However, there are fancier, newer land-based telescopes with arrays of smaller mirrors that can be adjusted to compensate for the atmosphere's effect. This means that a land-based telescope could be just as good as any space-based one, although the technology is still developing. Link to comment Share on other sites More sharing options...
dbzzx Posted February 24, 2006 Author Share Posted February 24, 2006 What can it see that a land telescope cant see though? I heard something about how stars are born and how they die.. Link to comment Share on other sites More sharing options...
swansont Posted February 24, 2006 Share Posted February 24, 2006 Another advantage of being in space is that the atmosphere tends to filter out large bands of the EM spectrum, so you can observe fequencies/wavelengths with a space-based telescope that you can't see on the ground.
