Ever since Isaac Newton and the falling apple, surprises have often pushed physics forward. Many truths about the universe we live in and the particles that make up ourselves and the world around us, as well as the forces that drive them, seemed to come out of left field when they were first discovered. For […]
Ein Forschungsteam behauptet, die ersten Sterne des Universums gefunden zu haben. Und es sind keine gewöhnlichen Sterne, sondern Objekte, die ihr Licht aus der Zerstrahlung von Dunkler Materie speisen.

The first stars were likely very different from the stars that light up our nights. The common hypothesis is that the first generation of stars were big—as much as a hundred times more massive than our Sun—and that they shone hot and bright from nuclear reactions in their cores. Another possibility is that these stars […]
In a first, the James Webb Space Telescope (JWST) might have glimpsed a rare type of star that astronomers aren’t even sure exists. These stellar objects, called dark stars, might have been fueled not by nuclear fusion but by the self-annihilation of dark matter—the invisible stuff that is thought to make up about 85 percent […]
The three objects spotted by Webb, which was launched in 2021 and began collecting data last year, were initially identified last December as some of the universe’s earliest-known galaxies but, according to researchers, instead might actually be humongous dark stars.
The big bang was the origin of everything in the universe. Or so we thought. Most – 95% no less – of the universe is dark matter and dark energy. It has long been assumed that the big bang was the origin of this dark matter and energy in the universe, as well as the […]
Since 2007, astronomers have proposed the existence of a weird type of star: one powered by the heat of dark matter. In cosmology, dark matter is a difficult thing to explain because we literally don’t know what it is. We can’t see it, hence the name “dark,” but without it factored into our equations of […]
Scientists for the past 15 years have been looking for evidence of a type of star only hypothesized but never observed – one powered not by the fusion of atoms like the sun and other ordinary stars but by mysterious stuff called dark matter.
NASA’s James Webb Space Telescope (JWST) has caught a glimpse of what could possibly be the first-ever ‘dark stars’
