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 ...

New work from Carnegie’s Alan Boss and Sandra Keiser provides surprising new details about the trigger that may have started the earliest phases of planet formation in our solar system. It is ...

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.

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 ...

Led by Purdue University assistant professor Cauê Borlina during his time at MIT, alongside senior author Benjamin Weiss, the research team published their findings in the Proceedings of the National ...

When most of us learn about the solar system, it seems like a pretty well-ordered place. Our sun formed first, about five billion years ago, and the planets appeared a little later. As a very general ...

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. The discovery of a planet ...

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.

If the outer solar system’s first solid bodies had come with a recipe, it would have called for a generous helping of chondrules, millimeter-sized beads of rock forged by heat, and very little icy ...

Look up on a clear night and it's easy to blur the line between the two. both feel like distant, abstract terms for "space ...
