A study led by MIRI mid-INfrared Disk Survey (#MINDS) GTO program, including researchers from #ULiège, using @nasawebb leads to the first detection of water in a disc containing forming planets 💦🌎🛰️

#PDS70

How does #water get onto #planets like #Earth? Until now, asteroids and comets were considered a possible source. Now, observations by the #MINDS consortium with the #JWST show that water could already be present during the formation of such planets.

In a #Nature article, #MPIA astronomer Giulia Perotti reports water in the planet-forming disk of the young star #PDS70. The water is located in the zone of this disk where rocky planets like Earth usually form.

An article published in the journal "Nature" reports the discovery of water in the very young PDS 70 system. A team of researchers from the MINDS collaboration led by Giulia Perotti of the Max Planck Institute for Astronomy (MPIA) in Heidelberg, Germany, used the James Webb Space Telescope to detect the presence of water in the inner region of the protoplanetary disk surrounding the star PDS 70.

Wie kommt #Wasser auf #Planeten wie die #Erde? Bislang galten Asteroiden und Kometen als mögliche Quellen.

Nun berichtet #MPIA-Astronomin Giulia #Perotti über die Entdeckung von Wasser in der Planeten bildenden Scheibe des jungen Sterns #PDS70. Und zwar dort, wo oft Gesteinsplaneten wie die Erde entstehen.

Somit könnte Wasser auf Gesteinsplaneten häufiger sein als bisher angenommen.

Die Ergebnisse basieren auf Beobachtungen mit dem #MIRI-Instrument des #JWST.
