Tag: HOPS-315

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 which ESO is a partner. Together with data from the James Webb Space Telescope (JWST), these observations show that hot minerals are beginning to solidify. In orange we see the distribution of carbon monoxide, blowing away from the star in a butterfly-shaped wind. In blue we see a narrow jet of silicon monoxide, also beaming away from the star. These gaseous winds and jets are common around baby stars like HOPS-315. Together the ALMA and JWST observations indicate that, in addition to these features, there is also a disc of gaseous silicon monoxide around the star that is condensing into solid silicates –– the first stages of planetary formation.

For the First Time Ever We Can See Planets Starting to Form Around a Star

JWST and ALMA peered through a natural opening in the star’s surrounding cloud to catch the action up close.
