Binary stars form lots of exoplanets, but many of them are ejected as rogue...
Astronomers don't have to work hard to find binary stars in the Milky Way.
They're common, even abundant. For a long time, they thought that...
Scientists finally discover the true edge of the Milky Way
For many years, astronomers have wondered where the Milky Way truly “ends.” Unlike a solid object, our galaxy does not have a clear boundary.
Its...
Potential signs of life on distant planets sound exciting, but confirmation can take years
Astronomers can use telescopes to find specific molecules in the atmospheres of neighboring planets, in nebulae—clouds of interstellar dust and gas—hundreds or thousands of...
