A UK team of astronomers report the first detection of matter falling into a black hole at 30% of the speed of light, located in the centre of the billion-light year distant galaxy PG211+143. The team, led by Professor Ken Pounds of the University of Leicester, used data from the European Space Agency’s X-ray observatory

Quantum jumps are usually regarded to be instantaneous. However, new measurement methods are so precise that it has now become possible to observe such a process and to measure its duration precisely — for example the famous ‘photoelectric effect’, first described by Albert Einstein. It was one of the crucial experiments in quantum physics: when

A team led by researchers from the Institute of Cosmos Sciences of the University of Barcelona (ICCUB, UB-IEEC) and the University of Groningen has found, through the analysis of Gaia data, substructures in the Milky Way that were previously unknown. The findings, which appeared when combining positions and speed of 6 million stars from the

Black holes form when stars die, allowing the matter in them to collapse into an extremely dense object from which not even light can escape. Astronomers theorize that massive black holes could also form at the birth of a galaxy, but so far nobody has been able to look far enough back in time to

Among the TV series Star Trek’s many charms are its rich universe of characters and planets. Now, the Dharma Planet Survey, in a new study led by University of Florida (UF) astronomer Jian Ge and team including Tennessee State University (TSU) astronomers Matthew Muterspaugh and Gregory Henry, has shown that science fiction may be a

An unusual infrared light emission from a nearby neutron star detected by NASA’s Hubble Space Telescope could indicate new features never before seen. One possibility is that there is a dusty disk surrounding the neutron star; another is that there is an energetic wind coming off the object and slamming into gas in interstellar space

In August of 2016, astronomers from the European Southern Observatory (ESO) confirmed the existence of an Earth-like planet around Proxima Centauri – the closest star to our solar system. In addition, they confirmed that this planet (Proxima b) orbited within its star’s habitable zone. Since then, multiple studies have been conducted to determine if Proxima

While last year’s discovery of gravitational waves from colliding neutron stars was earth-shaking, it won’t add extra dimensions to our understanding of the universe—not literal ones, at least. University of Chicago astronomers found no evidence for extra spatial dimensions to the universe based on the gravitational wave data. Their research, published in the Journal of

An international group of astronomers, including physicists at the University of St Andrews, has revived a previously debunked theory of gravity, arguing that motions within dwarf galaxies would be slower if close to a massive galaxy. The research team examined a theory previously published in the journal Nature which claimed that modified Newtonian dynamics (MOND)
