Scientists have first spotted an area where moons form around a planet outside our solar system, a Jupiter-like formation surrounded by a halo large enough to give birth to three moons the size of our own.
The researchers used the ALMA telescope in Chile’s Atacama Desert to observe the disk, which contains material that piles up in a vortex-like motion around one of two newborn planets orbiting a relatively close distance from Earth. turning a young star called BDS 70. is 370 light years old.
A light-year corresponds to a distance of about 9.5 trillion kilometers.
The moons are generated from these halos or disks that surround the planets. The researchers commented on the discovery, saying it allows a deeper understanding of the early life formation process for planets and moons.
More than 4,400 planets have been discovered outside our solar system, but no planet disks have yet been found because all known exoplanets so far reside in mature solar systems, except for the two newborn gas planets around the star (BDS 70).
“These observations are unique to date and we have waited a long time to put the theory of planet formation to the test and track the birth of planets and their moons,” said astronomer Myriam Benniste of the University of Grenoble, France, who led the study. research and published it Thursday in the Astrophysical Journal Letters, as it happens.’
The orange star (BDS 70) is about the same mass as the Sun and about 5 million light-years old, the twinkling of an eye in cosmic time, and the two planets are younger than it.
