And the earth was without form and void, and darkness was upon the face of the deep. Sometimes, if the night is dark and clear enough, you can look up and see the Milky Way in its arc across the sky.

A planetary system 116 light-years from Earth has a peculiar pattern. It could flip the script on how planets form, scientists say.

Astronomers have found a distant world that challenges planetary formation theory, with a rocky planet where gas giants should be.

Artist impression of the planetary system with four planets,around a small red star,called LHS1903. Caption: Astronomers have long thought solar systems follow a simple pattern similar to our own: ...

Scientists from MIT and their colleagues have estimated the lifetime of the solar nebula — a key stage during which much of the solar system evolution took shape. This new estimate suggests that the ...

Everything we know about the formation of solar systems might be wrong, says University of Florida astronomy professor Jian Ge and his postdoc, Bo Ma. They’ve discovered the first “binary-binary” – ...

Analysis of an ancient meteorite suggests that rocky planets both near and distant from the sun may have formed at the same ...

Estimating ages of specific events is one of the most difficult problems in astrophysics. While we have a precise (and probably accurate) age for the solar system, we do not have precise ages for each ...
