A tiny particle that smashed into Earth with a record-shattering energy of 220 petaelectronvolts could be the last scream of an evaporating black hole. According to a new theoretical paper, the 2023 neutrino event named KM3-230213A can be explained by a burst of Hawking radiation emitted as a primordial black hole puffed into nothing. Moreover, physicists Alexandra Klipfel and David …

Black holes are among the most feared objects in the universe.  These huge concentrations of tightly–packed matter, with a gravitational pull too strong for light to escape, can gobble up entire planets.  And according to scientists, one black hole in particular seems to have an unstoppable appetite.  Located 12.8 billion light–years away, the black hole, called RACS J0320–35, weighs about a billion …

Deep in the distant universe, astronomers have found a black hole that seems to be breaking the usual rules for how fast these cosmic beasts can grow.  The object, called RACS J0320-35, is so far away that its light has traveled 12.8 billion years to reach us, meaning we see it as just 920 million years after the Big Bang.  Even …

A supermassive black hole lurking at the center of M87, a supergiant galaxy 55 million light-years from Earth, is acting far more strangely than anticipated. Since 2017, astronomers from the Event Horizon Telescope (EHT) — an international collaboration combining a global network of radio telescopes — have closely watched the enormous gaping maw, resulting in the first-ever images of a …

In a jaw-dropping discovery, physicists have sounded the alarm over a black hole that could detonate within the next 10 years — triggering a cosmic event unlike anything humanity has ever witnessed. The “primordial black hole,” a mysterious relic from the dawn of time, has a 90% chance of exploding by 2035, according to scientists in Massachusetts. Potentially created mere …

Astronomers have spotted a monster black hole in the early universe that’s gorging on matter at more than twice the theoretical limit. The discovery deepens the mystery of how some black holes born shortly after the Big Bang managed to grow so big, so fast. Using NASA‘s Chandra X-ray Observatory — a powerful X-ray telescope at risk of being terminated …

In February 2016, scientists at the Laser Interferometer Gravitational wave Observatory (LIGO) announced the first detection of gravitational waves (GW). These ripples in space time, originally predicted by Einstein’s Theory of General Relativity, are caused by the merger of massive objects (like neutron stars and black holes). Since then, gravitational wave observatories like LIGO, VIRGO, and the Kamioka Gravitational Wave …

A black hole is growing at one of the fastest rates ever recorded, according to a team of astronomers. This discovery from NASA’s Chandra X-ray Observatory may help explain how some black holes can reach enormous masses relatively quickly after the big bang. The black hole weighs about a billion times the mass of the Sun and is located about …
