Black Hole

According to scientists, the engine that powers energetic and short-lived gamma-ray bursts must always come from a newly formed black hole. However, a new study contradicts this scientific orthodoxy. The study by Dr. Nuria Jordana-Mitjans at the University of Bath suggests that some short-duration GRBs are triggered by the birth…

LONDON (AP) — Britain’s Treasury chief warned Sunday of a coming spending crunch and tax increases for cash-strapped Britons as he bids to fill the “black hole” in the country’s finances. Billing himself as a Scrooge figure ahead of Thursday’s Autumn Statement, when he will update Parliament on the government’s…

Gamma-ray bursts (GRBs) have been detected by satellites orbiting Earth as luminous flashes of the most energetic gamma-ray radiation lasting milliseconds to hundreds of seconds. These catastrophic blasts occur in distant galaxies, billions of light years from Earth. A sub-type of GRB known as a short-duration GRB starts life when…

Massive black holes (BHs) at the centers of massive galaxies are ubiquitous. However, their population in dwarf galaxies remains elusive. Identification of these systems has historically relied on detecting light emitted from accreting gaseous disks close to the black holes. Without this light, they are difficult to detect. An international…

Zamani) Astronomers have discovered the nearest known black hole to Earth, and it’s twice as close as the previous record holder. The space-time singularity, named Gaia BH1, is 1,566 light-years…

        | Published: Tuesday, November 8, 2022, 14:04 Astronomers have discovered our newest celestial neighbor in the form of a massive black hole. The newly discovered black hole is ten times bigger than our Sun, and is located around 1,600 light-years away in the constellation Ophiuchus, The…

Black holes are awesome and powerful and can seem a bit scary thanks to their reputation for gravitational pulls so strong not even light can escape. So let's give a big welcome to Gaia BH1, the new closest black hole to Earth. It was hard to find, but a team…

WEBWIRE – Friday, September 23, 2022 Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have spotted signs of a ‘hot spot’ orbiting Sagittarius A*, the black hole at the centre of our galaxy. The finding helps us better understand the enigmatic and dynamic environment of our supermassive black hole. “We…
