Forget the “little green men” — it’s the “little red dots” in the early universe that caught the attention of the James Webb Space Telescope (JWST). The strange red bodies, scientists say, hide stars that models suggest are “too old” to have existed in early cosmic times and black holes thousands of times more massive … Read more
How can young galaxies in the early universe have old stars? That’s the question a team of astronomers set out to answer using the JWST as a probe. They first discovered the massive objects in 2022 and are still working on an explanation for these things. The infrared-sensitive JWST recently focused on three of these … Read more

During the collision of binary neutron stars, hot neutrinos can become briefly stuck at the interface, leaving them out of equilibrium with the cold cores of the merging stars for 2 to 3 milliseconds. This interaction helps drive the particles toward equilibrium and provides new insights into the physics of such mergers. Credit: SciTechDaily.com New … Read more
Stars near the center of our galaxy could be forever fueled by dark matter, according to a team of astronomers who recently studied the distant light sources. Florida family sues NASA over home damaged by space debris The group of stars, known as S-cluster stars, are located just three light-years from the center of the … Read more
It’s the Manchester hotel that celebrities are flocking to at the moment. Nicki Minaj, David Beckham, Liam Gallagher and Olly Murs have all stayed at the luxurious Stock Exchange Hotel in recent weeks. She even booked the entire hotel for a week with her entourage when she chose the city to rehearse for the opening … Read more
“All good things must come to an end.” That saying applies both in the cosmos and on Earth. We know that stars, like everything else, must die. When they run out of the fuel needed for nuclear fusion in their cores, stars of all sizes collapse under their own gravity and die, forming a dense … Read more
When it comes to ‘wiping out’ cosmic ghosts, only the most extreme objects in the universe are capable of doing so: neutron stars. Scientists have run simulations of collisions between these ultra-dense and dead stars, showing that such powerful events can briefly “capture” neutrinos, also known as “ghost particles.” The discovery could help scientists better … Read more
In our rapidly expanding universe, the lives of stars follow well-worn tracks, fusing hydrogen and then helium before growing in size until they exhaust their nuclear fuels and collapse, no longer able to resist gravity. But some stars in the innermost part of our Milky Way, very close to the galactic center, could chart their … Read more
Scientists have directly imaged eight dim objects in Gaia’s data catalog that accompany very bright stars, including so-called “failed stars,” also known as brown dwarfs. The stars and their companions were originally identified from millions of stars in the Gaia catalog. They were considered ideal for follow-up research with the ground-based GRAVITY instrument, an advanced … Read more
