🔭 Webb telescope peers into a stellar nursery 161,000 light-years away

If you look at the latest Picture of the Month from the James Webb Space Telescope, you are seeing dense clumps of gas where young stars are actively forming. The region, called LHA 120-N 159 (or N159), sits 161,000 light-years away in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. The image spans about 230 light-years and reveals a turbulent cauldron of star birth. Why it matter…

Stellar activity may be making some mega-Earths look heavier than they are

A new study posted to arXiv suggests that stellar activity can mimic the signal of a much heavier planet. Some rocky planets reported to weigh more than 10 Earths may not be as massive as they appear, with their apparent heft being an illusion caused by the star's own activity. This matters because it challenges how we identify and characterize the most massive rocky planets.

What other ex…
