Cosmic Chemical Detectives: Unveiling the Secrets of Protoplanets and Star-Birthing Clouds

Scientists using the ALMA observatory have discovered strong chemical evidence of a protoplanet in the protoplanetary disk around young star HD 169142. The detection of silicon monosulfide provides a new method for detecting and studying protoplanets, offering insights into protoplanetary chemistry. This discovery opens up new possibilities for detecting and characterizing protoplanets when direct observations or imaging are not possible, deepening our understanding of exoplanets and their development over time.

"Discovery: Protoplanet Found 374 Light Years Away, Shaping a New World"

Astronomers have confirmed the existence of a protoplanet, HD169142 b, located 374 light years away from Earth. Using data from the SPHERE instrument of the European Southern Observatory, researchers from the University of Liège and Monash University were able to detect the thermal signature of the forming planet. The protoplanet, which is still in the process of gathering material, is located in a disk of gas and dust surrounding the star HD 169142. This discovery increases the number of confirmed protoplanets to three and provides valuable insights into the early stages of planet formation. Further observations with the James Webb Space Telescope could provide additional characterization and confirmation of the protoplanet.

Third Protoplanet HD 169142 b Confirmed by Researchers

Researchers from the University of Liège and Monash University have confirmed the existence of a third protoplanet, HD 169142 b, using data from the SPHERE instrument of the European Southern Observatory. The protoplanet is located in the disk of gas and dust surrounding HD 169142, a star 374 light years from our solar system. The discovery was made possible by advanced image processing tools developed by the PSILab of the University of Liège. The protoplanet is still gathering material and is buried in a significant amount of dust, which could be in the form of a circumplanetary disk. Further characterization of the protoplanet could be obtained through future observations with the James Webb Space Telescope.

New Planet Confirmed by Researchers

Monash University astronomers have confirmed the formation of a protoplanet in the HD 169142 system using near-infrared images captured by the European Southern Observatory's Very Large Telescope. The protoplanet is located approximately 37 au from the star and has carved a gap in the disk surrounding it. The planet is buried in a significant amount of dust, which reflects stellar light, and is expected to have a circumplanetary disk that could form small satellites such as moons. The discovery of HD 169142 b is the third exoplanet to be imaged during formation, and it is an exciting target for the recently deployed James Webb Space Telescope.
