In reality, a black hole’s gravitational influence is limited. Like any other massive object, its pull weakens with distance. According to NASA, even the supermassive black hole at the centre of the Milky Way, Sagittarius A, only strongly affects the stars in its immediate neighbourhood. Located about 26,000 light years from Earth, it poses no threat to our planet. Most …

A black hole’s bizarre “heartbeat” is forcing astronomers to reconsider how these cosmic heavyweights behave. Observations of IGR J17091-3624 — a black hole in a binary system roughly 28,000 light-years from Earth — were taken using NASA’s Imaging X-ray Polarimetry Explorer (IXPE). Nicknamed the “heartbeat” black hole for its dramatic, rhythmic pulses in brightness, the object feeds on matter stolen …

Astronomers have confirmed the earliest, most distant black hole yet – and it’s surprisingly monstrous for its time. Residing in a galaxy called CAPERS-LRD-z9, it was already approximately 300 million times the mass of the Sun just 500 million years after the Big Bang, when the baby Universe was just 3 percent of its current age. Additionally, this discovery sheds …

Scientists may have spotted a never-before-seen kind of supernova, after using a Spotify-like artificial intelligence (AI) to scan the skies for strange activity. The AI unearthed signs of what could have been a huge star blowing up just as it was attempting to gulp down a nearby black hole. The stellar explosion, dubbed SN 2023zkd, was spotted in July 2023 …

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 …
