A powerful blast from the supermassive black hole may explain a lack of large, red stars there
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
Theories on how the Milky Way formed are set to be rewritten following discoveries about the behavior of some of its oldest stars.
There are at least 300 million habitable planets in the Milky Way, new NASA research has shown – hinting that it’s less likely that humanity is alone in the universe.
Most stars in the central 1,000 light-years of the Milky Way’s hub formed when it was swollen with infalling gas more than 10 billion years ago, according to astronomers from the Blanco DECam Bulge Survey.
First fast radio burst found in our galaxy is traced to magnetar 30,000 light years away
Astronomers have discovered a planetary free agent floating through the Milky Way, unbound to the gravity of any nearby stars. The discovery, detailed Thursday in Astrophysical Journal Letters, suggests the Milky Way may be teeming with rogue planets.
Astronomers get to the heart of the Milky Way.
