Strings of detectors, lowered into Russia’s Lake Baikal, the world’s deepest lake, will form one of several neutrino telescopes. Bair Shaybonov/Baikal-GVD By Daniel CleryMar. 31, 2021 , 11:40 AM Since 2010, IceCube, a detector frozen in the ice beneath the South Pole, has snared neutrinos from deep space. The universe […]

By Leah Crane A sight of the accumulation disc around a supermassive black hole, with jet-like frameworks moving far from the disc DESY, Science Communication Lab In a far-off galaxy, a supermassive black hole torn a star to little bits, sending out out a massive blast of power. For the […]
When a supermassive black hole splits a celebrity apart (envisioned below), it generates massive light– as well as possibly neutrinos, also. DESY/Science Communication Lab By Daniel CleryFeb 22, 2021, 11:00 AM Neutrinos are almost everywhere– trillions of the basically massless bits go through your body every secondly– yet they’re infamously […]
Astronomers call it “spaghettification,” and it’s not a pretty idea: It’s what happens when you venture too close to a black hole and fall in. Tidal forces stretch you and break you like a noodle, then your shreds circle the black hole until they collide and knock each other in. […]
Death by ‘spaghettification’: Scientists capture a star being shredded into thin streams of gas as it is devoured by a supermassive black hole The extreme gravitational forces from the black hole tore material off of the star Normally, these so-called ‘tidal disruption events’ are hidden by clouds of dust This […]
This illustration depicts a star (in the foreground) experiencing spaghettification as it’s sucked in by a supermassive black hole (in the background). M. Kornmesser/ESO Astronomers at the European Southern Observatory observed a black hole sucking in a faraway star, shredding it into thin strands of stellar material. This process, known […]
When stars pass close to a black hole, tidal forces tear it apart, producing a bright flare of radiation as material from the star falls into the black hole. Astronomers study the light from these Tidal Disruption Events (TDEs) for clues to the feeding behaviour of the supermassive black holes […]
Dr Avi Loeb said: “Once they melt, the small bodies are subject to tidal disruption by the black hole, followed by accretion from the tidally disrupted body onto the black hole.” Because black holes are virtually invisible to all instruments, astronomers have to instead look for their radiation signatures. In […]
