The stars in this study range in ages from very young to middle-aged like our Sun. This new study shows how comets play a role in the formation of stars and planetary systems. Credit: Luca Matra.

The mysterious Oort cloud is the source of many of our solar system's comets, but astronomers still have no idea what it looks like. Now, new simulations may have given them a first glimpse.

There are plenty of short-period comets buzzing around the inner Solar System, but they shed some of their outer layer of ice on every visit. Even those that started off quite large have shrunk ...

“Some comets are like couples—they break up, but then they get back together down the road,” says Distinguished Professor Daniel Scheeres of the Ann and H.J. Smead Department of Aerospace Engineering ...

By studying pictures collected by Rosetta from August 2014 (when the spacecraft met up with the comet) and March 2015, scientists looked at the layers of the comet to figure out that it was likely ...

A relatively new breed of chicken that has only appeared on the market in the last several years, Golden Comet Chickens are great egg layers, friendly, and curious. Along with their great ...

A widely held view is that these vital components were deposited on Earth by a long bombardment of icy comets. Comets are made of dust and ice. Astronomers have examined the water contained in ...

which likely happened because the boulder's movement exposed icy layers beneath it. As remnants of the primordial solar system, comets tell a lot about the early stage of solar system, making them ...
