In 2023, astronomers recorded one of the most extraordinary space explosions they had ever seen. It took place some 750 million light-years away, flaring into the detectors of the Zwicky Transient Facility on 7 July. At first, it looked just like a normal supernova – the explosive death of a star – and astronomers named it SN 2023zkd. Six months …

A recent discovery by a team of astronomers centres on a galaxy cluster called CHIPS 1911+4455, located an incredible 6 billion light-years from Earth. At its heart lies a supermassive black hole that has only recently ‘turned on’, just a thousand years ago. While that might sound like a long time, it’s merely a blink of an eye in astronomical …

Astronomers have observed what may be the first known case of a massive star exploding while interacting with a black hole, marking a discovery that could reveal an entirely new class of stellar explosions. The event, named SN 2023zkd, was first spotted in July 2023 by the Zwicky Transient Facility in California. Located in a galaxy with little ongoing star …

The massive “Cosmic Horseshoe” galaxy system likely hosts a colossal black hole measuring 36 billion times the mass of our sun — one of the largest ever seen in the universe, a new study finds. Scientists found the cosmic monster by peering through a halo of light called an “Einstein ring,” which is a kind of gravitational lens. Lensing happens …

‘Black hole morsels’: A Stephen Hawking theory could reveal strange new objects that challenge physics  Live Science Source link

Written by Michael Allen An international team of astronomers using NASA’s IXPE (Imaging X-ray Polarimetry Explorer), has challenged our understanding of what happens to matter in the direct vicinity of a black hole. With IXPE, astronomers can study incoming X-rays and measure the polarization, a property of light that describes the direction of its electric field. The polarization degree is …

Black holes are dark, menacing objects with gravity so intense that not even light can escape, so you don’t want to mess with them. A recent discovery of one of the strangest supernovas ever observed reveals the tragic story of a star that tried to defy the powerful pull of a nearby black hole but later conceded in an explosive …

Astronomers have identified what could be a new supermassive black hole, and with an estimated mass 36 billion times that of the sun, it is about 10,000 times heavier than the black hole at the center of the Milky Way. This would make it among the most massive objects ever detected. The finding, published in the Monthly Notice of the …

An astrophysicist has made an ambitious proposal for how humanity could probe the extreme physics of black holes — by sending a spaceship no bigger than a paperclip to our nearest one. The spacecraft, no heavier than a gram and propelled to a third of the speed of light by lasers on Earth, would gather information on a nearby space-time …
