A new study published by University of Chicago researchers challenges the notion that the force of an exploding star forced the formation of the solar system. In this study, published online last ...

The discovery of a planet that is far too massive for its sun is calling into question what was previously understood about the formation of planets and their solar systems.

Ultimately, without a time machine, we will never fully recover the precise history of our solar system's formation, so we will never be entirely sure what role giant impacts had in the ...

On a Hawaiian mountaintop in the summer of 1992, a pair of scientists spotted a pinprick of light inching through the constellation Pisces. That unassuming object — located over a billion kilometers ...

An image from the ALMA telescope array in Chile shows jets of silicon monoxide blowing away from the young star HOPS-315. The blue jet is moving towards Earth, and the red jet is moving away from us.

A region of active star formation in the constellation Ophiuchus is giving astronomers new insights into the conditions in which our own solar system was born. In particular, a new study of the ...

A research team led by University of Minnesota School of Physics and Astronomy Professor Yong-Zhong Qian uses new models and evidence from meteorites to show that a low-mass supernova triggered the ...

HOPS-315 is also giving astronomers a new opportunity to study early planet formation, serving as a stand-in for newborn solar systems across the galaxy.
