Previously dormant supermassive black hole Ansky in galaxy SDSS1335+0728, approximately 300 million light-years away in Virgo, started emitting exceptional X-ray flares in late 2019. These quasiperiodic eruptions last 10 times longer, shine 10 times brighter, and release 100 times more energy than typical black hole bursts. ESA’s XMM-Newton and NASA telescopes have recorded 165 such events since February 2024.
Astrophysicists at Tohoku University in Japan have suggested a new theory for the origin of supermassive black holes using large computer simulations. The theory helps to further explain the massive number of black holes currently observed. Nearly every galaxy in…
Astronomers found a supermassive black hole in an active galactic nucleus producing rapid and periodic eruptions of X-rays every nine hours. The nucleus contains about 400 000 times the mass of the Sun and is about 250 million light-years from Earth. According to a…
An intriguing source has been discovered in the nearby Andromeda galaxy using data from NASA's Chandra X-ray Observatory and ground-based optical telescopes. Previously thought to be part of the Milky Way's neighbor galaxy, the new research shows this source…
For the first time ever, astronomers at The University of New Mexico say they've been able to observe and measure the orbital motion between two supermassive black holes hundreds of millions of light years from Earth – a discovery more than a decade in the…
NASA's scientists obtained images of a huge jet of particles blasted from a supermassive black hole at the center of the Pictor A galaxy. The continuous X-ray emission spread across the distance of 300 000 light years which is three times the diameter of Milky…
Black holes have always been one of the most mysterious and awe inspiring objects in space. Astronomers have known for some time that black holes periodically emit very powerful flares into space. New observations from NASA's Explorer missions Swift and the…
I have been arguing for years that the so-called black holes are nothing more than extremely powerful magnetic field regions formed in dense space plasma. These regions are similar to sunspots and coronal holes. However, in extremely dense plasma – specifically at the
A supermassive blackhole has been found inside the tiniest galaxy ever found, the M60-UCD1, located about 54 million light years away from Earth. Researchers used NASA’s Hubble and the Gemini North 8-meter optical and infrared telescope on Hawaii to observe and
No matter what your thoughts and opinions might be on the nature of our universe and Big Bang cosmology here is an interesting video, or better yet, a simulation of what astronomers call the first realistic virtual universe.The super-computer simulation, called &qu
