Why is the mysterious object Cygnus X-3 so bright? Astronomers may now find the answer

A binary system containing a massive star and possibly a black hole, together being a source of intense X-rays, has been shown to be a smaller-scale example of some of the brightest quasars on Earth. Universe. New findings from an international team used NASA‘S Imaging X-ray Polarimetry Explorer spacecraft (IXPE), approximately 24,000 images of an… Read More »

Supermassive black hole winds blowing at 36 million miles per hour could shape entire galaxies

A bright quasar powered by a supermassive black hole is blasting radiation that pushes surrounding gas clouds to produce winds reaching speeds of about 36 million miles per hour (58 million kilometers per hour). Oh, and the quasar is almost as old as the universe itself. The discovery, made by a team of scientists led… Read More »

How could 2 quasars from the beginning of time be Rosetta stones for the early universe?

Just 900 million years after the Big Bang, a pair of quasars have been discovered spiraling towards a massive merger, illuminating the “cosmic dawn”. They are the first quasar The couple was detected this far back in cosmic time. Quasars are growing rapidly supermassive black holes in the nuclei of the hyperactive galaxies. Showers of… Read More »

12 billion years of black hole history revealed by X-rays and simulations

As astronomers chronicle the growth of galaxies by combining X-ray observations with detailed supercomputer models, the history of the dark hearts of galaxies has been told almost completely for the first time. supermassive black holes More than 12 billion years of cosmic history. By doing this, scientists showed that there is a black hole at… Read More »

The star that exploded like a nuclear bomb still raises questions half a century later

What happened after the thermonuclear explosion? binary star System observed approximately 3,400 light-years away Hubble space telescope. HM Sagittae, or HM Sge for short, is a system known as the symbiotic system. white dwarf feeding on a friend red giant star. The stolen material forms an accretion disk orbiting the white dwarf. If too much… Read More »

Turbulent spacetime and destroyed stars help reveal how fast supermassive black holes spin

The “shaking” remains of a star that suffered a grisly death at the maw of a supermassive black hole have helped reveal the spin rate of the cosmic predator. Supermassive black holes are believed to be born through successive mergers of smaller black holes; Each of these brings with it angular momentum that accelerates the… Read More »

Scientists use XRISM spacecraft to predict fate of matter around monster supermassive black hole

Black hole week is in full swing at this point, and to celebrate, NASA has released stunning observations of the heart of a distant spiral galaxy, as well as the monster supermassive black hole that lives within that heart. The observations were carried out by the X-ray Imaging and Spectroscopy Mission (XRISM), led by the… Read More »

Scientists use artificial intelligence to recreate energetic explosion from Milky Way’s supermassive black hole

Scientists used artificial intelligence to create a three-dimensional model of an energetic explosion, or flare, occurring around the Milky Way’s central black hole, Sagittarius A* (Sgr A*). This 3D model could help scientists develop a clearer picture of the turbulent environment that generally forms around supermassive black holes. The material orbiting Sgr A* is found… Read More »

Supermassive black hole’s mysterious hiccup likely originates from neighboring black hole’s ‘punch’

A hiccuping supermassive black hole has alerted astronomers to an entirely new kind of black hole behavior. In 2020, at the heart of a galaxy about 800 million light-years from Earth, a black hole with a mass equivalent to 50 million suns suddenly exploded, illuminating the material around it by a factor of 1,000. A… Read More »

Brightest quasar ever seen is powered by black hole eating ‘one sun a day’

A newly discovered quasar is a real record breaker. It is not only the brightest quasar ever seen, but also the brightest astronomical object ever seen overall. It is also powered by the hungriest and fastest-growing black hole ever seen; This black hole consumes the equivalent of the mass of one Sun per day. Quasar… Read More »
