Astronomers Capture First Direct Image of Swirling Gas Around Protoplanet

• An international research team has captured the first direct image of a protoplanet, WISPIT 2b, surrounded by swirling gas using the ALMA observatory in Chile.
• The imagery confirms disk-planet interaction patterns previously known only through computer simulations.

The WISPIT 2 System

• WISPIT 2b: Located 430 light-years from Earth, it is approximately five times the mass of Jupiter and resides 57 AU from its host star.
• WISPIT 2c: An inner companion planet located at 15 AU with an estimated mass of 8 to 12 Jupiters.
• Environmental Impact: WISPIT 2c has cleared a 'cavity' in the disk, while WISPIT 2b has created a 'gap,' allowing scientists to distinguish between total material clearing and localized depletion.

Significance for Planetary Formation

• The data offers new insight into accretion, the process where rocks and gas clump together to form planets.
• Utilizing 66 radio dishes, ALMA achieved high-resolution imaging that reveals gas dynamics previously unseen, bridging the gap between theoretical models and observed physical reality.
