A new study by a group of researchers at the University of Birmingham has found that collisions of supermassive black holes may be simultaneously observable in both gravitational waves and X-rays at the beginning of the next decade.The European Space Agency (…

Simultaneous spectral and temporal observations of the newly detected black hole X-ray binary (BHXB) MAXI J1820+070 using the AstroSat spacecraft, have delivered more insights into the properties of this source. Results of the study, presented in a paper publ…

The popular mobile video app TikTok is a gold mine, featuring everything from dancing to angry voicemails, snappy rants, and brilliant sketch comedy. Only problem: You have to wade through a lot of rough lip syncs to get to them.   The app's elusive "For You…

Climbing out of the black hole called credit card debt seems impossible. Since credit cards have such high interest rates, making the minimum payment can feel like the cards will never get paid off. Many of us have thousands of dollars in credit card debt. …

The jets emanating from a famous black hole are cruising along at about 99% the speed of light, according to new observations. Researchers spotted the speedy jets emanating from a black hole in the galaxy Messier 87 (M87) — the same black hole that was image…

One morning I woke up to see the front page of every newspaper across the world covered with pictures of what looked like a big orange doughnut. What could this represent? I learned that the doughnut picture was rendered by combining images taken from telesco…
