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” – ...

Most of our knowledge about the Solar System’s formation and evolution comes from the study of extraterrestrial rock samples called chondritic meteorites. These rocks, which are fragments of asteroids ...

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 ...
