Planetary-Mass Exomoon Found Circling Brown Dwarf

Astronomers using ESO’s Very Large Telescope (VLT) have discovered a gas giant around a brown dwarf in the stellar system CD-35 2722. The post Planetary-Mass Exomoon Found Circling Brown Dwarf appeared first on Sci.News: Breaking Science News.

Scientists Discover Massive Alien "Exosatellite"

Scientists have discovered a puzzling object in a distant star system that defies classification. Hear us out. The object in question orbits a brown dwarf. A brown dwarf is a substellar type of object that larger than a gas giant but smaller than the smallest stars. And this brown dwarf, in turn, orbits the system’s main star. Since the newly-identified object doesn’t orbit a planet, it technically isn’t a “moon” by any normal definition, but it…

We assumed exomoons would be easy to find once we had the technology — but moons are small, dim, and hidden in the glare of their host, and it took until July 2026 and a radial-velocity wobble on a brown dwarf before astronomers had their first plausible detection

For years, exomoons felt like one of those astronomical discoveries that should arrive almost automatically once telescopes became sensitive enough. We had found thousands of planets around other stars. Our own Solar System contains more moons than planets. Surely the first moon beyond it was mostly a matter of waiting. I had absorbed that assumption without examining it closely. Then I read the paper behind the July 2026 report from the CD-35 2…

After Discovering 6,000 Exoplanets, Researchers May Have Found the First Exomoon

The moon is about the size of Jupiter, and it orbits a brown dwarf instead of a regular planet.
