resolution, electromagnetic waves and binary stars
... Angular Resolution: The smallest angle of separation between two objects that can be resolved by a telescope. Binary Star: Two stars very close together in the sky. They can be close together in space, like T Tau, or they can be far apart in space, but along the same line of sight for the observer – ...

25 light years from Earth, there`s a planet about the size of our own
... About 900 light years from here, there's a rocky planet not much bigger than Earth. It goes around its star once every hundred days, a trifle fast, but not too different from a standard Earth-year. At least two and possibly three other planets circle the same star, forming a complete solar system. I ...
