The study found two such instances. One in the 760 million light-year away galaxy cluster Abell 133. Second one found in the 3.2 billion light-year-distance Abell 1758S galaxy cluster. NASA‘s Chandra X-ray Observatory was used in a new study that tracked two pairs of supermassive black holes in dwarf galaxies on collision courses, the agency … Read more
A study claims the object is 1,560 light-years from Earth and 10 times larger than our sun. Dormant Milky Way stellar mass Gaia BH1 was confirmed. Follow-up studies proved that the pair comprises a normal star and at least one inactive black hole. The International Gemini Observatory found the nearest black hole to Earth. A … Read more
Twitter account shared video that sounds like a black hole. Most of space is a vacuum, thus there’s no sound there. We can hear sounds from a galaxy cluster’s gas. Nasa Twitter page says that they are “the NASA team looking for planets and life beyond our solar system.” We represent all of NASA’s missions … Read more
Black holes are one of Einstein’s most profound predictions in his general theory of relativity. They were first investigated as a mathematical consequence of the theory rather than as physically meaningful objects, but they quickly evolved into generic and sometimes unavoidable results of the gravitational collapse that produces a galaxy. In fact, most physicists believe … Read more
The Event Horizon Telescope (EHT), has caught a spectacular image of a black hole jet in Centaurus A. The huge virtual telescope effectively focuses a large number of dishes at the same time towards a celestial object and precisely time stamps the data from each one with an atomic clock. These are eventually reassembled using … Read more
On January 5, 2020, astrophysicists detected a chirp from 900 million light-years away in the cosmos. The brief sound was unlike anything they’d ever heard before, and it was created by a massive ripple in space-time – a gravitational wave – that spread out over the universe from over 900 million light-years away, washing over … Read more
