  • Scientists see moons forming around an exoplanet.

    As far the current observed planets in other solar systems they pretty much all have moons. We can see moons forming around an exoplanet.

    Astronomers See Moons Forming in Disk Around Distant Exoplanet

    Scientists have never before gotten such a clear view of moons in the making.

    July 23, 2021, 10:45 a.m. ETOur solar system is home to a magnificent menagerie of moons, from icy ones filled with turbulent oceans to volcanic ones decorated with pits of raging hellfire. To date, astronomers have discovered 4,438 worlds orbiting other stars, and there is no doubt that diverse moons dance around most of these exoplanets. But stargazers have yet to conclusively find any — these exomoons have proven too small and too far-flung to be spotted.

    Now, after years of observations of a pair of Jupiter-like exoplanets nearly 400 light-years from Earth, astronomers have found the next best thing: a disk of debris orbiting one of these worlds, a ring of rock and gas gradually coalescing under its own gravity. In other words, astronomers have caught a circumplanetary foundry in the act of making moons.

    This is the first time such a feature has been unambiguously detected. And unlike many extrasolar discoveries, this object was not found through indirect methods — the subtle wobbling of a star revealing the presence of an orbiting planet, for example. This disk was effectively photographed. This is a real image of a baby planet surrounded by its very own moon-making forge.

    Astronomers are unreservedly thrilled, and a little lost for words. “I don’t have coherent scientific thoughts. I just look at the image and say ‘wow’, every time I see it,” said Bruce Macintosh, an astronomer at Stanford University not involved with the study.

    At this stage it'll take many, many moons for them to coalesce into moons
