Astr: Black Holes & Quasars

In Black holes, matter is squeezed into a tiny space, making gravity so intense that not even light can escape. This can happen when a massive star collapses at the end of its life. Many galaxies have massive black holes in their center; thus, some black hole pins are in the Galaxies Galore board. Quasars are massive & extremely remote objects that emit exceptionally large amounts of energy. Quasars may contain massive black holes & may represent a stage in the evolution of some galaxies.

Massive jets of material shooting from a black hole dwarf even the largest galaxies | CNN

Astronomers have spotted a massive pair of jets releasing material from a distant black hole. The jets are so large they span about 140 Milky Way galaxies in length.

Scientists Discovered Something Kinda Alarming: The Universe Shouldn't Actually Exist

A team of scientists has now argued that the existence of primordial black holes should have triggered the “bubbling” of the Higgs field to such a degree that nothing should have ever been able to form.

IMBH candidate in Omega Centauri

An international team of astronomers has used more than 500 images from the NASA/ESA Hubble Space Telescope spanning two decades to detect seven fast-moving stars in the innermost region of Omega Centauri, the largest and brightest globular cluster in the sky. These stars provide compelling new evidence for the presence of an intermediate-mass black hole.

Massive black holes may eat differently in small galaxies than in large ones

This artist’s concept shows a black hole (center) surrounded by a hot accretion disk of material. Optical and infrared light are believed to come from the outer accretion disk, while X-rays are generated in a corona close to the black hole.
