The Milky Way's core will be visible this month and through August. Here's what Tennessee stargazers should know.

The Milky Way consists of roughly 100 billion stars that form a huge stellar disk with a diameter of 100-200 thousand light years. The Sun is part of this structure, hence, when we look into the ...

Researchers thought this disk formed around 8 to 10 billion years ago, ... which runs about 3,200 light-years around the sun; for comparison, the entire Milky Way is about 100,000 light-years wide.

This famous effect — first seen in the orbit of the planet Mercury around the Sun — was the first evidence in favor of General Relativity," co-author Reinhard Genzel said in a press release.
