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 ...

Leonardo Testi and team investigate the initial conditions for planet formation in this special astronomy focus ...

This is HOPS-315, a baby star where astronomers have observed evidence for the earliest stages of planet formation. The image was taken with the Atacama Large Millimeter/submillimeter Array (ALMA). In ...

Here’s what you’ll learn when you read this story: Observations of the young HOPS-315 star system show an environment analogous to what our own nascent Solar System would have looked like billions of ...

About 4.6 billion years ago, the Solar System formed from a cloud of dust and gas collapsing in on itself due to gravity. The Sun, planets, and eventually Earth formed out of the cloud. But when did ...

In a groundbreaking discovery, astronomers have, for the first time, observed the formation of a new solar system. Using a combination of data from the Atacama Large Millimeter/submillimeter Array ...

Our solar system is a smashing success. A new study suggests that from its earliest period — even before the last of its nebular gas had been consumed — Earth’s solar system and its planets looked ...
