Astronomers have witnessed the birth of a planetary system that could one day resemble the solar system. The discovery offers scientists a proxy to study how our home planetary system formed around the sun around 4.6 billion years ago.

The team was able to pinpoint the moment specks of material that will one day forge planets began to form around the infant star HOPS-315, located around 1,300 light-years away.

The breakthrough was made possible with data from the Atacama Large Millimeter/ submillimeter Array (ALMA), an array of 66 radio telescopes located in the desert of northern Chile, and observations from the James Webb Space Telescope (JWST).

I saw this today and I thought it was pretty cool! I don’t think it classifies as a planet since it’s way smaller than Pluto, but still neat nevertheless.
