Astronomers believe they might have found the source of the brightest explosion ever in space. The record-breaking explosion recorded in October 2022 was the most powerful ever seen, leaving equipment and instruments struggling to measure it as it pointed directly at planet Earth. The bright gamma-ray burst is officially called GRB 221009A and when it first went off, scientists were left scrabbling to point telescopes in its direction to record it. The explosion has affectionately been nicknamed BOAT, standing for “brightest of all time”, and was caused by the death of a large star located 2.4 billion light-years away – relatively close in terms of space activity. The star collapsed into a black hole after ejecting its outer envelope, causing this huge, bright explosion comprised of gamma rays, producing not only a narrow structured jet but with an additional outflow of gas.

The study’s lead author and astronomer from George Washington University, Brendan O'Connor, explained: “GRB 221009A represents a massive step forward in our understanding of gamma-ray bursts, and demonstrates that the most extreme explosions do not obey the standard physics assumed for garden variety gamma-ray bursts.” He continued: “GRB 221009A might be the equivalent Rosetta stone of long GRBs, forcing us to revise our standard theories of how relativistic outflows are formed in collapsing massive stars.” The huge and long-lasting blast measured up to 18 teraelectronvolts which is a staggering record for a gamma-ray burst, leaving scientists to hypothesise that it was a supernova.

It feels like there have been staggering science stories emerging every other day recently, all of which have blown our tiny little minds. First, there was the discovery of a terrifying black hole pointing right at us, then there was a huge hole found in the sun and a missing continent found after going missing for 375 years. Now, people are only just realising that there’s a massive ocean hidden under the Earth’s crust. It turns out there’s a huge supply of water 400 miles underground stored in rock known as 'ringwoodite'. Sign up to our new free Indy100 weekly newsletter Scientists previously discovered that water is stored inside mantle rock in a sponge-like state, which isn’t a liquid, solid or a gas, but instead a fourth state. The scientific paper titled ‘Dehydration melting at the top of the lower mantle’ was published in 2014 and laid out the findings. "The ringwoodite is like a sponge, soaking up water, there is something very special about the crystal structure of ringwoodite that allows it to attract hydrogen and trap water," said geophysicist Steve Jacobsen at the time. "This mineral can contain a lot of water under conditions of the deep mantle,” added Jacobsen, who was part of the team behind the discovery. He added: "I think we are finally seeing evidence for a whole-Earth water cycle, which may help explain the vast amount of liquid water on the surface of our habitable planet. Scientists have been looking for this missing deep water for decades." Scientists made the findings at the time after studying earthquakes and discovering that seismometers were picking up shockwaves under the surface of the Earth. From that, they were able to establish that the water was being held in the rock known as ringwoodite. If the rock contained just 1 per cent water, it would mean that there is three times more water under the surface of the Earth than there is in the oceans on the surface.

The structure of the Earth beneath our feet has been fascinating to members of the scientific community recently, and it turns out it’s far more complex than people initially thought. First, we learned of the news that there’s a massive ocean beneath the Earth’s crust which contains more water than all of the seas on the surface. Now, another study has been published which has taken an in-depth look at the geology beneath the southern hemisphere. The new research, published in Science Advances, has found evidence that an entire ocean floor actually runs the length around the core. Sign up to our new free Indy100 weekly newsletter This is a relatively thin layer that sits on the core-mantle boundary around 1,800 miles beneath the surface of the Earth. It's an ancient formation that could provide more insight into the structure of the planet beneath our feet. Geologist Samantha Hansen and her colleagues from the University of Alabama led the research. They observed the structure by using 15 monitoring stations under the ice of Antarctica, mapping the waves from earthquakes. Doing this allowed them to analyse the structure of the Earth below the surface, including the ultra-low velocity zones where waves moved much slower. "Seismic investigations, such as ours, provide the highest resolution imaging of the interior structure of our planet, and we are finding that this structure is vastly more complicated than once thought," Hansen said. "Analyzing [thousands] of seismic recordings from Antarctica, our high-definition imaging method found thin anomalous zones of material at the CMB everywhere we probed," geophysicist Edward Garnero from Arizona State University also said. "The material's thickness varies from a few kilometers to [tens] of kilometers. This suggests we are seeing mountains on the core, in some places up to five times taller than Mt. Everest." "Our research provides important connections between shallow and deep Earth structure and the overall processes driving our planet," Hansen added. Have your say in our news democracy.

Sharon Horgan has opened up about having post-traumatic stress disorder (PTSD) after her eldest daughter was diagnosed with meningitis as a baby. The Irish actor, who will star in the forthcoming BBC One drama Best Interests with Michael Sheen, said she drew on the experience in order to play her character in the new series. Horgan’s daughter survived the life-threatening illness, but it left an “aftershock” on her mother. “We were so unbelievably lucky and we know that,” the Bad Sisters star told The Times in a new interview, published today (Sunday 11 June). “But the aftershock – there’s definitely PTSD and I dealt with any of my second daughter’s illnesses with blind panic because you always think, ‘If it can happen, why couldn’t it happen again?’” Both of Horgan’s daughters, Sadhbh and Amer, are now teenagers. She shares them with her ex-husband, Jeremy Rainbird. Best Interests tells the story of Nicci (Horgan), a mother who sues the NHS after doctors decide her Marnie (Niamh Moriarty) should be taken off life support after her condition, muscular dystrophy, deteriorates. Horgan stars opposite Sheen, who plays Nicci’s husband Andrew. In the show, Andrew is torn between his love for Marnie and his unwillingness to support his wife’s case. The friction between Nicci and Andrew shows that they “had a real relationship that has difficulties”, Horgan said. “When things get really, really bad, the accusations are there, a certain amount of finger-pointing, which happens anyway, just even in normal parenting,” she explained. After her divorce from Rainbird in 2019, Horgan said the adjustment to co-parenting made her doubt if she was a good mother. During an appearance on Desert Island Discs in 2020, she told host Lauren Laverne: “I was fun mum for years. I entirely thought that was my role but that changes when you co-parent. “Everything changes and you take on a lot more roles and I am much more practical than I was, and I think that is a positive thing.” She continued: “It had some dips in the middle where I thought, ‘Oh, that thing I thought I was, which was a good mother, I am not entirely sure about’. “When you bring anything like that into your kid’s life it’s tricky, when you turn the roles upside down, but it balances out and everything eased back.” Read More Shapewear is booming, and body image experts are worried: ‘It’s really dangerous’ Chris Hemsworth thanks wife Elsa Pataky for her ‘forgiveness’ Kelis addresses Bill Murray dating rumours for the first time Sharon Horgan opens up about ‘aftershock’ after daughter’s meningitis Jamie Foxx’s rep addresses conspiracy Covid vaccine left actor ‘paralyzed and blind’ Debate sparker over parent who wouldn’t give her daughter any birthday cake
