As KKs 3, the dwarf galaxy, has been newly discovered, we have a new resident in our galactic neighborhood. The discovery of such galaxy has been released in The Monthly Notices of the Royal Astronomical Society and its photo has been captured by the Hubble Space Telescope. Although it is the new […]

Monster Galaxies Bulk Up by Eating Smaller Neighbors

According to the latest survey targeting on 22,000 galaxies, massive galaxies have ended up in producing their own stars, but begin with gobbling small nearby galaxies instead. In our own galaxy: Milky Way, we still can observe the remains of engulfed galaxies, however, it would take its comeuppance finally, because, […]

Super Massive Black Holes “Eat” Less Material than Expected

An image shows the emission around the Milky Way’s supermassive black hole (SMBH) in X-rays (blue) and infrared (purple and yellow). The inset is an X-ray close-up of the black hole’s immediate neighborhood (half a light-year wide). *Image source: Sky & Telescope. Taking advantage of the NASA’ super-sensitive Chandra X-ray […]
