This new black hole is bigger than Sagittarius A, and can devour 1 Earth per second. A rapidly expanding black hole got spotted by researchers from the Australia National University (ANU), and it still grows in the present, as the study authors saw it using the SkyMapper Telescope in the university.

Our sun is travelling around the center of the Milky Way at 220 kilometers per second, says Gerry Gilmore with the Institute of Astronomy at the the University of Cambridge, referring to the fact that our Milky Way Galaxy lies inside a sphere, or “halo”, of dark matter that extends out far beyond the luminous Galactic disk, surrounded by a spheroidal halo of old stars and globular clusters, of which 90% lie within 100,000 light-years of the Galactic Center. “If there were no dark matter there, adds Gilmore, if there were just stars, we would be travelling at a ‘mere’ 150 km per s...
Astronomers find origins of "galactic cannibalism" with discovery of ancient dark matter halo By Sophie Lewis Galaxy without dark matter Astronomers have detected what they believe to be one of the earliest instances of "galactic cannibalism" — when one galaxy consumes one of its smaller neighbors — in an ultrafaint dwarf galaxy called Tucana II. The findings stem from the discovery of an ancient dark matter halo, located in a galaxy 163,000 light years from Earth. Tucana II is just one of dozens of dwarf galaxies surrounding the Milky Way. They are thought to be ar...
