‘Monster stars’ 10,000 times bigger than the Sun detected for first time
Scientists have been peering into the depths of space, looking right back at the early days of the universe, and they’ve found something very interesting indeed. Researchers using the James Webb Space Telescope have come across a discovery that indicates some of the very earliest stars to ever form in the universe were staggering in scale, measuring 10,000 times bigger than the Sun. "Today, thanks to the data collected by the James-Webb Space Telescope, we believe we have found a first clue of the presence of these extraordinary stars," says astrophysicist Corinne Charbonnel of the University of Geneva in Switzerland, in research published in Astronomy & Astrophysics. These features are huge collections of between 100,000 and 1 million stars known as globular clusters, which all feature similar properties. Scientists estimate that they were all formed at the same time.

The cores of these stars are much hotter than those we see in stars today, and scientists suggest it could be down to an excess of hydrogen burning at high temperatures. It’s thought that smaller stars collided with the supermassive stars and relished their energy. However, now most of these global clusters are approaching the very end of their life spans. "Globular clusters are between 10 and 13 billion years old, whereas the maximum lifespan of superstars is two million years," said Mark Gieles, previously at the University of Surrey but now at the University of Barcelona, back in 2018. "They therefore disappeared very early from the clusters that are currently observable. Only indirect traces remain." The researcher states: "If the supermassive star scenario can be firmed up by future studies, this would provide an important step for our understanding of globular clusters and for the formation of supermassive stars in general, with numerous important implications.” Have your say in our news democracy.

Ryan Mason believes Tottenham are still an attractive proposition for managers
Ryan Mason insists the Tottenham job remains an attractive proposition despite another protracted search for the head coach role. Spurs saw another contender to permanently replace Antonio Conte exit the running this week after Feyenoord boss Arne Slot committed his long-term future to the Eredivisie club before he signed a new deal on Friday. Tottenham held an interest in Slot but no direct discussions with the 44-year-old took place, the PA news agency understands. Other managers linked with the vacancy, such as Bayer Leverkusen head coach Xabi Alonso and Burnley boss Vincent Kompany, have also pledged their immediate futures to their current clubs, but acting head coach Mason is under no illusions the top job at Spurs remains desirable. Asked if the Tottenham job was still an attractive proposition, Mason replied: “Absolutely, yes. “It is Tottenham Hotspur, it is a big club. Not just for managers or coaches, but for staff members, for players. “Anyone here should feel the privilege and honour to represent the badge. If they don’t, then they shouldn’t be here. It is as simple as that.” When Conte left his position on March 26, Tottenham were firmly in the race for Champions League qualification but they travel to relegation-threatened Leeds on Sunday with only a faint chance of securing a place in the Europa Conference League. It is Tottenham Hotspur, it is a big club. Not just for managers or coaches, but for staff members, for players Ryan Mason Mason insisted that, while European football for next season is crucial, the most important task for the club is to put a plan in place. “Obviously it has its implications and it’s not where the football club wants to be. We definitely want to be competing in Europe,” Spurs’ acting head coach stated. “Any European competition is important for a club this size but at the same time the most important thing, regardless of whether we’re in or out of Europe, is that there is a plan and there is commitment from everyone to that going forward.” During the last few weeks, Mason has repeatedly referenced the need for commitment at the club without going into specifics. Even before Conte departed two months ago, the future of the Italian was uncertain with his deal set to expire this summer anyway. Mason again refused to be drawn on whether any coaches, players or staff had lacked commitment this season, but admitted the squad had been affected by the turmoil off the pitch. He added: “The results before he (Conte) left weren’t amazing. I don’t think results have dipped a huge amount. “Obviously we were in a different position but I think you could feel it, you could feel it the weeks leading up to it there was uncertainty and it’s never great to have that uncertainty. “We’ve probably been in that situation for the last eight weeks where there’s been a lot of uncertainty. “That is why one of my main things when me and my team of people came in, I wanted to create a togetherness and make us feel part of something towards the end of the season.” Read More Charity boss speaks out over ‘traumatic’ encounter with royal aide Ukraine war’s heaviest fight rages in east - follow live Rankings don’t lie – Dan Evans believes British tennis has soul-searching to do Cameron Norrie sees Lyon title defence ended by Francisco Cerundolo Mikel Arteta braced for even harder Premier League challenge next season
