New Exoplanet Discovery Builds Better Understanding Of Planet Formation

by SpaceRef August 6, 2023July 15, 2024
This image, taken with the Atacama Large Millimeter/submillimeter Array (ALMA), in which ESO is a partner, shows the young planetary system PDS 70, located nearly 400 light-years away from Earth. The system features a star at its centre, around which the planet PDS 70 b (highlighted with a solid yellow circle) is orbiting. On the same orbit as PDS 70b, indicated by a solid yellow ellipse, astronomers have detected a cloud of debris (circled by a yellow dotted line) that could be the building blocks of a new planet or the remnants of one already formed. The ring-like structure that dominates the image is a circumstellar disc of material, out of which planets are forming. There is in fact another planet in this system: PDS 70c, seen at 3 o’clock right next to the inner rim of the disc. CREDIT ALMA (ESO/NAOJ/NRAO) /Balsalobre-Ruza et al.

Ariel Data Challenges 2023 Calling AI experts! Join The Hunt For Exoplanets

Image of the HD 169142 system showing the signal of the forming planet HD 169142 b (around 11 o'clock), as well as a bright spiral arm resulting from the dynamic interaction between the planet and the disc in which it is located. The signal from the star, 100,000 times brighter than the planet, was subtracted by a combination of optical components and image processing (mask in the centre of the image). Observations at different times show the planet advancing in its orbit over time. Image obtained with ESO's VLT/SPHERE instrument. CREDIT V.Chrisitaens / ULiège
