We Might Be Wrong About Planet Formation

The video discusses a significant exoplanet discovery by a US-Japanese team, highlighting the direct imaging of a young exoplanet, AB Aurigae b, which is still forming. The discovery challenges existing planet formation theories, particularly core accretion, and supports the disk instability model. The video details the observational techniques used, including the Hubble and Subaru telescopes, and the implications of the findings for understanding planet formation.
