We sort-of take it for granted that there’s a supermassive black hole at the center of the Milky Way galaxy, but we can’t really go there and check. What if something else is actually lurking in this messy, dusty region?

Scientists have known for a decade that two bubbles of charged particles, or plasma, flank the plane of the Milky Way. Those structures, known as the Fermi bubbles after the telescope that detected them, are visible in high-energy light called gamma rays. But now, the eROSITA X-ray telescope has revealed larger bubbles, seen in X-rays. The X-ray bubbles extend about 45,000 light-years above and below the center of the galaxy, researchers report online December 9 in Nature.

Source: Phys.org Scientists working with data from the Sloan Digital Sky Surveys’ Apache Point Observatory Galactic Evolution Experiment (APOGEE) have discovered a “fossil galaxy” hidden in the depths of our own Milky Way. This result, published today in Monthly Notices of the Royal Astronomical Society, may shake up our understanding of how the Milky Way
