For The First Time, Astronomers Witness a Moon-Forming Disk Around an Exoplanet

The process of planetary formation is complex and multilayered. Even with all the data available on exoplanets there are only two planets still not fully formed.These two planets are known as PDS 70b or 70c. They were discovered by the Very Large Telescope and are among the most useful objects that we have for constructing our planetary formation models. Now, it has been proven that one of the planets is surrounded by a moon-forming disc.ALMA observations provided additional insight. ALMA observations provided additional insight. Astronomers knew for a long time that PDS 70c was enclosed by such a disc, but the images taken previously were not sufficient to prove its existence. It has now been confirmed physically beyond any doubt.The moon formation is less understood than the formation of planetary bodies at this point. The origins of the Moon's existence are still a mystery. The discovery of PDS 70c could help us to see the possibility of creating at least one. There is enough material in this disk to make three moons around Jupiter-like planet.The moon formation process is also important in planetary formation. Circumplanetary disks can also form moons, which may influence the creation of the planet. Scientists will be able to observe the disk change as they build models of moon formation and planetary formation.This evolution will take many millions of years. However, PDS 70c is currently the only planet known to have any type of circumplanetary disc.Its existence was confirmed by the same data set. This showed that PDS 70b, its Saturn-like twin (like PDS 70b), does not have the disk some scientists previously believed. Other telescopes might be available, but for now this is all we have.The uniqueness of the PDS 70 system will ensure that it remains a focal point for plenty of observational firepower. There is one important thing you should look at with these instruments. Hopefully, there will be even more information.Universe Today originally published this article.
