Microwave signals are being sent through space through electromagnetic waves and not through optical waves. This type of signal is being used mainly in communications because of its narrower beams compared to other signals.
Free Space Loss is the primary source of signal loss in satellites. As the signal propagates through the atmosphere it disperses. With normal terrestrial antennas, the distance is so short that this is rarely an issue. However, the great distances that satellites must communicate over make this a major problem for global space-based communication.

Yes! Men usually see more of empty space when they look at optical illusions. When women tend to look into the detail.
As of August 2014 human colonization of space has yet to have been established. Long term presence in space has been ongoing through orbital space craft and stations however.

You can get a radio signal from space on your computer using SETI.
A microwave is near the "red" side of the electromagnetic scale. All electromagnetic travels at the same rate. Light is a form of electromagnetic radiation which travels through a vacuum (space). Thereofore, being a part of electormagnetic radiation, microwaves will travel through a vacuum.
In space, there is no interference by Earth's atmosphere.
Actually they are.
The Hubble Space Telescope has a number of instruments, but the primary one is an optical telescope.
No, this microwave can be mounted right underneath the cabinet without any venting space required.
