Earth has been hit by a blast from a dead star so energetic that scientists cannot explain it. The burst of gamma rays, originating in a dead star known as a pulsar, is the most high energy of its kind ever seen. It was equivalent about ten trillion times the energy of visible light, or 20 tera-electronvolts. Scientists are unable to explain exactly what kind of a scenario could lead a pulsar to emit such intense energy, and the researchers behind the breakthrough say that it “requires a rethinking of how these natural accelerators work”. Scientists hope that they can find yet more powerful energy blasts from pulsars, with a view to better understanding how they are formed. Pulsars are formed when a star dies, exploding in a supernova and leaving behind a tiny, dead star. They are just 20 kilometres across, and spin extremely fast with a powerful magnetic field. “These dead stars are almost entirely made up of neutrons and are incredibly dense: a teaspoon of their material has a mass of more than five billion tonnes, or about 900 times the mass of the Great Pyramid of Giza,” said Emma de Oña Wilhelmi, a scientist at the High Energy Stereoscopic System observatory in Namibia that detected the blast. As pulsars spin, they throw out beams of electromagnetic radiation, throwing it out like a cosmic lighthouse. That means that someone in one spot – like the Earth – will see the radiation pulses flash in a regular rhythm as they spin past. The radiation is thought to be the result of fast electrons that are produced and thrown out by the the pulsar’s magnetosphere, which is made up of plasma and electromagnetic fields that surround the star and spin with it. Scientists can search the radiation for different energy bands within the electromagnetic spectrum, helping them understand it. When scientists previously did that with the Vela pulsar examined in the new study, they found that it was the brightest everseen in the radio band, and the brightest persistent source in the giga-electronvolts. But the new research found that there is a part of the radiation with even more high energy components. “That is about 200 times more energetic than all radiation ever detected before from this object,” said co-author Christo Venter from the North-West University in South Africa. Scientists don’t know exactly how that could happen. 
“This result challenges our previous knowledge of pulsars and requires a rethinking of how these natural accelerators work,” says Arache Djannati-Atai from the Astroparticle & Cosmology (APC) laboratory in France, who led the research. “The traditional scheme according to which particles are accelerated along magnetic field lines within or slightly outside the magnetosphere cannot sufficiently explain our observations. “Perhaps we are witnessing the acceleration of particles through the so-called magnetic reconnection process beyond the light cylinder, which still somehow preserves the rotational pattern? But even this scenario faces difficulties to explain how such extreme radiation is produced.” An article describing the findings, ‘Discovery of a Radiation Component from the Vela Pulsar Reaching 20 Teraelectronvolts’, is published today in the journal Nature Astronomy.

Scientists have got to the bottom of a 5-year mystery after finally identifying a tiny sea creature captured on camera in 2018. It is the latest in a series of oceanic discoveries and experts recently observed “zombie worms” devour an alligator in an incredible experiment. For the tiny creature, the baffling question of its identity took a team of zoologists and parasitic worm specialists to solve after the small creature was pictured by an underwater photographer in 2018 off the coast of Okinawa in Japan. After photographer Ryo Minemizu captured the image, he shared it on social media asking the hive mind if they knew what the creature was, but everyone was left stumped. Minemizu was determined not to give up and instead went back to the area and was able to capture another ladybird-sized creature that was the same, or very similar, to the original one he had come across. The research team that was interested in identifying the sea creature approached him and Minemizu sent them the sample to research. Your browser does not support the video tag. Current Biology (2023) The team’s results were published in the Current Biology journal putting an end to the 5-year long mystery baffling experts. In a fascinating twist, the team found that the sample was not one, but two creatures that were clinging tightly to one another. Both were identified as types of cercariae parasitic larvae worms, with experts dubbing one as the “sailor” and the other as a “passenger” thanks to how they behave when they are connected. Passengers were much smaller than the sailors and when they were bonded together, they formed a flat-topped hemisphere shape. They squeeze their bodies together with heads facing the inside of the sphere, meanwhile, their tails latch onto one another. Experts believe the two individual creatures have created a colonial organism that suits both of their needs and according to the study's authors, “represents the first case of labor division in digenean larvae”.

Aston Villa return to Europa Conference League action as they try to get their qualification hopes back on track against Bosnian champions Zrinjski Mostar. Playing European football for the first time in 13 years and having successfully negotiated Hibernian in the play-off round, Villa’s group stage started in disappointing fashion as they twice came from behind to equalise through Jhon Duran and Lucas Digne away to Legia Warsaw but eventually went down 3-2 in the Polish capital. That means victory over eight-time Bosnian title winners Zrinjski, who have climbed back to the top of the domestic game since Krunoslav Rendulic took over as manager last November, is a must and Unai Emery’s men are in good form since that defeat in Warsaw. They have beaten Chelsea and Brighton in the Premier League – the latter in a shock 6-1 thumping at the weekend – and will be heavy favourites to triumph on home turf, although Zrinjski are currently top of Group E after stunningly coming from 3-0 down at half-time to beat AZ Alkmaar 4-3 in their Europa Conference League opener. Here’s everything you need to know ahead of the fixture; see all the latest Europa League odds and tips for tonight here. When is Aston Villa vs Zrinjski Mostar? The match kicks off at 8pm BST on Thursday 5 October at Villa Park in Aston, Birmingham. How can I watch it? Viewers in the United Kingdom can watch the match live on TNT Sports 2, with coverage on the channel from 7:45pm BST. Subscribers can stream the action via discovery+, which is also available via Amazon Prime.

Viewers using a VPN need to make sure that they comply with any local regulations where they are and also with the terms of their service provider. What is the team news? Villa were hit by the news that Boubacar Kamara, Moussa Diaby and Jacob Ramsey would all miss the match earlier this week, while Alex Moreno is out until after the international break and both Tyrone Mings and Emi Buendia are long-term absentees. Leon Bailey should be back in contention after a thigh strain, however. Krunoslav Rendulic normally favours a 4-3-3 formation with Tomislav Kis and Nemanja Bilbija in contention to lead the line and Zvonimir Kozulj pushing for a start after scoring twice in Zrinjski’s remarkable comeback against AZ last month. Predicted line-ups Aston Villa: Olsen; Cash, Konsa, Lenglet, Digne; Luiz, Tielemans; Traore, McGinn, Zaniolo; Duran Zrinjski Mostar: Maric; Corluka, Jakovljevic, Radic, Memija; Ivancic, Balic, Kozulj; Cuze, Kis, Ticinovic Odds Aston Villa win 1/10 Draw 10/1 Zrinjski Mostar win 30/1 Get the latest football odds here Prediction Villa to build on their impressive Premier League form and get their qualification hopes back on track.
