Astronomers Find the First Moon Orbiting an Exoplanet in PDS 70 System! - The Cosmic Companion July 22, 2021
For the first time ever, astronomers find a moon forming around an exoplanet.
The PDS 70 star system is home to at least one moon, the first exomoon conclusively found in another solar system.
The PDS 70 star system is home to at least one moon, the first exomoon conclusively found in another solar system.
Astronomers using the Atacama Large Millimetre/submillimeter Array (ALMA) report finding disks of dust and gas surrounding an exoplanet for the first time. This finding provides the first clear evidence for a moon forming around a planet in an alien star system.
Almost 400 light years from Earth, the PDS 70 star system is home to at least two massive Jupiter-like planets.
Earlier examination of one of these exoplanets, PDS 70c, showed hints of a moon-forming disk surrounding this world. However, an inability to distinguish this disk from the surrounding material made a definitive confirmation impossible. Until now.
