Sort of. The electromagnetic noise that's in the television bands is at too high of a frequency to get through the earth's ionosphere. However, frequencies in the AM radio band (roughly 550-1600 kHz) can, and much (maybe half) of the "static" heard between stations on AM radios is from the sun, Jupiter, and the Milky Way's magnetic field.
Stars emit very weakly at radio frequencies, so the only star we can detect by radio is our own sun.

Snow on a television is video static. The presence of radio waves that have no viable signal. However.....you can turn the brightness down to just below where the snow disappears and the screen is "off"....(outdoor antenna works best here) during a meteor shower and the screen will brighten every time a meteor flashes across the sky. ( due to ionization particles of the rock burning thru the atmosphere)

No...
A little more information would help. Do you have this problem with cable or just using an old antenna?
If you are using cable - then it could be your cable, radio interference from an airport, cell phone tower or even being close to power transformers (power lines) can cause problems.
If you are using traditional external antenna, then a host of stuff could be the culprit - direction of the antenna, the above mentioned items and the strength of the TV signal itself.

The snow is strictly a low signal.
You must increase the signal or the snow will stay.
Even if you amplify the signal you will amplify the snow also,you must increase the signal to noise ratio.

Supposedly, some of it is caused by the left over radiation of the Big Bang.
