The Earth has been hit by a powerful blast of energy from the very depths of the universe. The fast radio burst is the most distant of its kind of ever seen, coming from so far away that it has travelled eight billion years to get to Earth. It is also astonishingly powerful, one of the most energetic of its kind ever seen. In less than a second, it released the same energy that comes out of the Sun in more than 30 years. Fast radio bursts are intense, short bursts of energy that come from unknown but extreme activity in space. Scientists are still unsure of how they are formed, but explanations have included everything from extraterrestrial technology to neutron stars. The newly discovered burst appears to come from a small group of merging galaxies, scientists say, which helps support current theories about where they come from. But the intensity of the burst is harder to explain, which challenges our understanding of how they are actually emitted. “While we still don’t know what causes these massive bursts of energy, the paper confirms that fast radio bursts are common events in the cosmos and that we will be able to use them to detect matter between galaxies, and better understand the structure of the Universe,” said Ryan Shannon, from the Swinburne University of Technology. The blasts could be useful ways of answering some of the deepest questions about our cosmos, such as how much it actually weighs. At the moment, attempts to answer that have led to confusing results. “If we count up the amount of normal matter in the Universe — the atoms that we are all made of — we find that more than half of what should be there today is missing,” said Professor Shannon. “We think that the missing matter is hiding in the space between galaxies, but it may just be so hot and diffuse that it’s impossible to see using normal techniques. “Fast radio bursts sense this ionised material. Even in space that is nearly perfectly empty they can ‘see’ all the electrons, and that allows us to measure how much stuff is between the galaxies.” The blast was spotted last year, using a telescope in Japan. Researchers then used other telescopes to verify the find and examine it in more detail. “Using ASKAP’s array of dishes, we were able to determine precisely where the burst came from,” said Stuart Ryder, the first author on the paper. “Then we used the European Southern Observatory (ESO) Very Large Telescope (VLT) in Chile to search for the source galaxy, finding it to be older and further away than any other FRB source found to date, and likely within a small group of merging galaxies.” The findings are reported in a new paper, ‘A luminous fast radio burst that probes the Universe at redshift 1’, published in the journal Science.

The f-word is often thought of as the most useful and flexible word in English. Whether that’s true or not, the term is so successful that it’s spawned dozens of euphemisms. Here are a few of them.

An unknown source has been sending radio blasts towards Earth since at least 1988, scientists say. The researchers do not know what object is sending the radio waves towards Earth. The nature of the waves is such that they do not conform with any models that attempt to explain it. For 35 years, the source has been sending out regular 20-minute blasts of energy that vary considerably in their brightness, researchers say. The emissions appear something like the blasts that come out of pulsars or fast radio bursts, which last for milliseconds to several seconds. But the newly discovered source sends radio signals that pulsate on a period of 21 minutes – something previously thought impossible by expected explanations. Pulsars are neutron stars that spin around quickly, throwing out radio blasts as they do. When one crosses Earth, the emissions can be picked up very briefly and brightly, like being in the path of the light from a rotating lighthouse. Scientists believe that process can only work if the magnetic field of the pulsar is strong, and it is rotating quickly enough – if not, there would not be enough energy to see the pulsar from Earth. That has led to the development of the “pulsar death line”, which suggests that sources must be spinning fast and strong enough to be detected. The newly discovered object named GPMJ1839-10, however, is way beyond that death line. If it is a pulsar, then it seems to be operating in ways that scientists thought impossible. It could also be a highly magnetised white dwarf or magnetar, an extra kind of neutron star with incredibly strong magnetic fields. But they do not tend to send out emissions of this kind, researchers believe. The signals have been detected on Earth since at least 1988, scientists found by going through old records, but they had gone unnoticed by those collecting that data. After the source was detected, researchers checked radio archives and found that the source has been repeating for at least 35 years. Yet more discoveries may be made in this way in the future, said Victoria M Kaspi, a professor of physics at McGill University who did not work on the study. “Only time will tell what else lurks in these data, and what observations across many astronomical timescales will reveal,” she wrote in an accompanying article. That might include some explanation of how unusual the newly discovered source is. By examining whether there are is a similar collection of other objects in the data, researchers might be able to understand the mechanisms behind the newly discovered emissions. The findings are reported in a new paper, ‘A long-period radio transient active for three decades’, published in the journal Nature.

Sam Altman might still return to OpenAI after his ouster from the company, Microsoft chief Satya Nadella hinted. Chaos erupted at OpenAI on Friday as the company’s board abruptly fired its founder and chief Mr Altman, saying it “no longer has confidence in his ability to continue leading OpenAI”. Later, hundreds of the ChatGPT company’s employees threatened to quit unless its board resigned. When asked on Monday whether Mr Altman would join Microsoft, that has invested billions in the ChatGPT company, Mr Nadella said he was “open to both options”. “Look, that is for the OpenAI board and management and the employees to choose,” he told CNBC. “We obviously want Sam and Greg to have a fantastic home if they’re not going to be at OpenAI,” the Microsoft chief said. “We chose to explicitly partner with OpenAI and we want to continue to do so, and obviously, that depends on the people of OpenAI staying there or coming to Microsoft,” Mr Nadella had said. Microsoft later officially announced it was hiring Mr Altman and OpenAI co-founder Greg Brockman, who resigned on Friday. “Extremely excited to share the news that Sam Altman and Greg Brockman, together with colleagues, will be joining Microsoft to lead a new advanced AI research team,” Mr Nadella said in a post on X. “We look forward to moving quickly to provide them with the resources needed for their success,” he said. Mr Altman’s sacking was followed by about 500 staff at the company demanding the board’s resignation and the reinstatement of their dismissed boss. The employees signed a letter demanding OpenAI’s board resign and reinstate Mr Altman, claiming the decision to oust him jeopardised the company’s work. The letter was reportedly signed by several senior staff at OpenAI. Mira Murati, the company’s chief technology officer who was appointed as the interim chief following Mr Altman’s exit, was one of the signatories. Another signatory, Ilya Sutskever, the company’s chief scientist and one of the board members, expressed “deep regret” over the decision to remove Mr Altman. Employees at the company’s headquarters reportedly refused to attend an emergency all-hands meeting with new OpenAI boss Emmett Shear that was scheduled on Sunday. Some had responded to a Slack announcement with a middle-finger emoji, according to reports. Mr Nadella also said “it’s clear something has to change around the governance” at OpenAI. “We’ll have a good dialogue with their board on that, and walk through that as that evolves,” he said. Mr Altman said on X that his “top priority” remains to “ensure OpenAI continues to thrive”. “We are committed to fully providing continuity of operations to our partners and customers,” the ousted tech boss said on Monday. “We have more unity and commitment and focus than ever before. We are all going to work together some way or other, and I’m so excited. one team, one mission,” Mr Altman said.
