Scientists think they have found an explanation for what scientists thought was a “runaway” black hole speeding through the universe. Last month, scientists reported that they had seen what appeared to be an object unlike anything seen before. What originally appeared to be scratches on Hubble images was actually a black hole that had been thrown out from its home galaxy and was now speeding through the cosmos, scientists said. Astronomers had come to that conclusion after spotting a long trail of stars, formed 8 billion years ago. It was a stretched out, narrow shape, roughly the same size as our own Milky Way. Last month’s study suggested that those stars were the wake left behind from that runaway black hole. As the black hole travelled through a gas cloud, it left behind the right conditions to start forming stars, that study suggested. It was shock and a breakthrough for a number of reasons: it was unprecedented, and required a number of different conditions for it to be true. That led astronomers both to celebrate and question the theory, and in the time since other researchers have been working on their own ideas. Now scientists at the Instituto de Astrofísica de Canarias (IAC) have suggested their own, more ordinary explanation of the unusual, long star structure. They suggest that it is in fact just a flat or thin galaxy – one without a bulge that makes it wider – that is being seen from its side. “The motions, the size, and the quantity of stars fits what has been seen in galaxies within the local universe,” said Jorge Sanchez Almeida, an IAC researcher who is the first author of the article, in a statement. “It’s a relief to have found the solution to this mystery, the new proposed scenario is much simpler. In one sense it is also a pity, because the existence of fleeing black holes is expected, and this could have been the first one to be observed.” The team compared the mystery structure with another, much better known galaxy, named IC5249. That is near to us, has a similar mass of stars, and doesn’t have a galaxy either. They found that it was surprisingly similar. The stars were moving in similar ways to those found in closer, comparative galaxies, researchers said. That led scientists working on the new paper to suggest that it is a relatively normal and expected galaxy, rather than an out-of-control black hole. But they hope that further observations will shed further light on what exactly it is doing – and could still allow the galaxy to prove of interest to astronomers. “We also looked at the relation between the mass of the assumed galaxy and its maximum velocity of rotation, and discovered that indeed it is a galaxy which behaves like a galaxy,” said Ignacio Trujillo, an IAC researcher who worked on the study. “It is an interesting object, because it is quite a large galaxy at a very large distance from Earth, where the majority of the galaxies are smaller.” The proposal is reported in a paper, ‘Supermassive black hole wake or bulgeless edge-on galaxy?’, published in the journal Astronomy and Astrophysics.

Day 4 of the 2023 FIBA World Cup was a regression to expectations but still delivered plenty of basketball excitement thanks to Luka Doncic, Team USA, and a very physical showdown between Brazil and Spain.

Killer whales have sunk yet another boat in southwestern Europe, marking the fourth such incident in the region in the last two years. The latest attack saw a pod of orcas target a yacht in the Strait of Gibraltar for about 45 minutes, Polish cruise company Morskie Mile said in a Facebook post on 31 October. The boat’s operator said the relentless attack focused on the yacht’s steering fin and caused extensive damage and leakage. “Despite attempts to bring the yacht to the port by the captain, crew and rescuers from the SAR (Search and Rescue), port tugs and the Moroccan Navy, the unit sunk near the entrance to the port of Tanger Med,” the company said, while adding that the crew was “safe, unharmed, and sound”. The attack is the latest reported case of killer whales targetting boats in Gibraltar – a phenomenon that has intrigued animal behaviour scientists. Cases of orcas harassing boats passing by in the Strait of Gibraltar, which runs between Spain and Morocco and connects the Atlantic Ocean to the Mediterranean Sea, began being reported in 2020. The strange behaviour has perplexed scientists, with some theorising that the killer whales may be teaching each other to attack boats passing by in the region. Researchers have floated a number of theories to explain the behaviour of the aquatic mammals. These explanations range from food scarcity and the disruptive resumption of post-pandemic nautical activities to playful interactions. There have been documented cases of “play behaviour” among different orca populations as some killer whales in previous studies were shown to “harass” porpoises. Researchers suspect these were likely orchestrated by orcas as a form of social play to bond, communicate or simply for fun among themselves, and that the behaviour would provide benefits such as improved group coordination and teamwork. But scientists have also begun to investigate whether the Gibraltar attacks are linked to past trauma. Whatever the orcas’ motivation, such incidents have highlighted the more widespread concerns of scientists around the impact of human nautical activity on intelligent marine mammals.

Erik ten Hag will be hoping to improve on Manchester United’s third place finish in the Premier League last season and get the new campaign off to a winning start when his side host Wolverhampton Wanderers tonight. United have been busy this summer with the manager deciding to overhaul the squad ahead of the new season. David De Gea, the last player remaining from Sir Alex Ferguson’s era, has been released with the likes of Fred, Alex Telles, Anthony Elanga and Phil Jones also moved on. The arrivals of Andre Onana, Mason Mount and Rasmus Hojlund should bring an extra layer of dynamism and creativity to the team which should in theory help them close the gap on rivals Manchester City. Wolves, meanwhile, are hoping that a change of manager will not hinder their progress. The midlands team comfortably finished 13th last year but key players like Ruben Neves and Adama Traore have left the team. New boss Gary O’Neil kept Bournemouth in the top flight last year and may have a relegation battle on his hands again this term unless Wolves get off to a good start.
