Using the James Webb Space Telescope (JWST), astronomers have discovered clusters of stars in the “Cosmic Stones” arc that existed only 460 million years after the Big Bang. This marks the first discovery of star clusters in a newborn galaxy, seen when the 13.8 billion-year-old universe was less than 500 million years old. Originally discovered… Read More »
Researchers have discovered that elusive intermediate-mass black holes can form in dense star clusters containing tens of thousands to millions of tightly packed stars, called “globular clusters.” An intermediate-mass black hole has a mass between 100 and 10,000 suns. They are heavier than solar-mass black holes, which have masses between 10 and 100 solar masses,… Read More »
Astronomers have discovered one of the most powerful black hole explosions ever seen, and the massive explosion, which occurred almost 4 billion years ago, created a pattern of stars in jewel-like clusters. The starry necklace adorns a massive cluster of hundreds of galaxies called SDSS J1531; This object is located approximately 3.8 billion light years… Read More »
It’s called the Seven Sisters but in reality there are hundreds of stars in the Pleiades (Nasa) When you head out for stargazing on a dark night this month (well away from street lights), you’ll find that the sights on offer aren’t just stars and bright planet Jupiter. The shining band of the Milky Way… Read More »
