A new study using NASA's James Webb Space Telescope has identified the mysterious 'little red dots' as massive, short-lived stars, providing insights into the formation of the universe's first supermassive black holes and advancing our understanding of early cosmic history.
New research suggests that the mysterious Little Red Dots detected by the JWST in the early universe may be supermassive stars, which are crucial in understanding the formation of supermassive black holes, challenging previous ideas that they are galaxies or active galactic nuclei.
The Heart Nebula, also known as the Running Dog Nebula, is a colorful feature in the Cassiopeia constellation located about 7,500 light-years from Earth. Spanning an area larger than the Moon, the nebula's shape is influenced by supermassive stars in its core, with the blue colors resulting from ionized oxygen and sulfur. The image, captured by Paul Macklin, combines four separate mosaics and showcases the beauty of the universe.
Researchers from the universities of Geneva, Paris, and Barcelona have found evidence that supermassive stars existed within globular clusters when they formed 13 billion years ago. These clusters are the universe’s most massive and ancient star groupings, housing up to a million individual stars. The researchers believe that they have detected the initial chemical evidence of these stars in globular proto-clusters, which came into existence approximately 440 million years following the Big Bang. The results were obtained thanks to observations by the James-Webb space telescope.
Scientists using the James Webb Space Telescope have discovered evidence of "monster stars" that were 10,000 times bigger than the Sun and formed in the early universe. These stars were found in globular clusters, which are collections of between 100,000 and 1 million stars that were formed at the same time. The cores of these stars were much hotter than those seen in stars today, and scientists suggest it could be due to an excess of hydrogen burning at high temperatures. Most of these globular clusters are approaching the end of their life spans, but the discovery could provide important insights into the formation of supermassive stars.

A new study published in Astronomy & Astrophysics reveals that the weird composition of globular clusters may be the result of being baked by gigantic “monster stars” when the universe was young. These monster stars, 5,000 to 10,000 times the size of the Sun, quickly fused material into increasingly enriched matter, then spread that matter throughout the molecular cloud in a heterogeneous manner, which explains why some stars in a cluster will have significantly higher or lower concentrations of certain elements. The James Webb Space Telescope has confirmed high proportions of nitrogen in a globular cluster located 13.3 billion light-years away, which could only have been formed in the core of a supermassive star.
The James Webb Space Telescope has provided evidence of the presence of supermassive stars in the early Universe, with masses up to 10,000 Suns. The evidence comes from the study of globular clusters, which contain stars with similar chemical properties, suggesting they were born from the same cloud of gas. These clusters exhibit chemical abundance ratios that vary from star to star, which can be explained by hydrogen burning at extremely high temperatures in the cores of massive stars. The researchers hope to obtain more data on early galaxies from JWST to identify these early supermassive stars and resolve other mysteries, such as the formation of supermassive black holes.
NASA's James Webb Space Telescope has discovered evidence of millions of supermassive stars, 10,000 times the mass of our Sun, that existed just 440 million years after the Big Bang. These "celestial monsters" could provide insight into the early evolution of the cosmos.
The James Webb Space Telescope has discovered evidence of millions of supermassive stars up to 10,000 times the mass of the sun hiding at the dawn of the universe. These "celestial monsters" could shed light on how our universe was first seeded with heavy elements. Researchers found chemical traces of the gigantic stars inside globular clusters, many of which are among the most ancient to have ever formed in our universe. The researchers will look across more globular clusters in more galaxies to see if their discovery holds elsewhere.

The James Webb Space Telescope has helped astronomers detect the first chemical signs of supermassive stars, which are celestial monsters blazing with the brightness of millions of Suns in the early universe. The team of European researchers behind the study previously theorised the existence of supermassive stars in 2018 in an attempt to explain one of the great mysteries of astronomy. They found the chemical signs in the galaxy GN-z11, which is more than 13 billion light years away.
The James Webb Space Telescope has detected the first chemical signs of supermassive stars, which are "celestial monsters" that blaze with the brightness of millions of Suns in the early universe. The largest stars observed so far have a mass of around 300 times that of our Sun, but the supermassive star described in a new study has an estimated mass of 5,000 to 10,000 Suns. The researchers theorize that these huge stars are born from successive collisions in the tightly packed globular clusters, and they shoot out chemical "pollution" that feeds young forming stars, giving them a greater variety of chemicals.
