The observable universe contains around 40 billion billion (4x1019, or 40,000,000,000,000,000,000) black holes, according to a newly published estimate. If you can't get your mind around that figure, join the club – but another way of putting…
For the first time, astronomers have obtained polarimetric images at the event horizon scale of the black hole at the center of our Milky Way galaxy. This remarkable achievement provides a never-before-seen view of Sagittarius A* (or Sgr A*), the…
A black hole that is ejecting hot material into space at almost the speed of light has been seen by astronomers. This is an updated (quotes and sources) version of the previous article. The distance between a black hole and its partner star is…
NASA’s James Webb Space Telescope has recently made one of its most unexpected discoveries: tiny red dots scattered across some of the oldest corners of the universe. These seemingly innocuous dots turned out to be baby life stages of supermassiv…
Gravitational wave astronomy currently can only detect powerful rapid events, such as the mergers of neutron stars or stellar mass black holes. We've been very successful in detecting the мergers of stellar мass Ƅlack holes, Ƅut a long-terм goa…
An ultramassive black hole is a black hole that has a mass of more than 10 billion times the mass of the sun. Black holes are regions of space where gravity is so strong that nothing, not even light, can escape. They are usually formed when massive…
Introduction What if our universe is not the only one? What if it is just a tiny bubble inside a much larger and more complex reality? This is the idea behind the bubble universe theory, which suggests that our universe is one of many possible univ…
In March 2018, astronomers observed a sudden change in brightness of a galaxy located 239 million light-years away. Known as 1ES 1927+654, the galaxy had brightened by 100 in visible light. Further observation by the NASA-funded Asteroid Terrestria…
There is a black hole in our backyard. Astronomers have found the closest black hole yet at just 1000 light years from Earth, close enough to see the stars that orbit it without a telescope. Marianne Heida at the European Southern Observatory in…
The Jaмes WeƄƄ Space Telescope detected what мay Ƅe the oldest known Ƅlack hole in the uniʋerse Ƅy deconstructing faint gliммers of light froм close to the dawn of tiмe. The Jaмes WeƄƄ Space Telescope has spotted the earliest known Ƅlack hole in th…
Astronomers have discovered a half-dozen galaxies, which formed within the first billion years of the universe, blockading a supermassive black hole. This artist’s concept shows the six galaxies, which astronomers think might just be the brighte…
Glimpsed only occasionally at the hearts of massive clusters of galaxies, ultramassive black holes are some of the largest and most elusive objects in the universe. These black hole behemoths have masses exceeding that of 10 billion suns, makin…
Some 7 billion light-years away, two black holes swirled closer and closer together over eons until they crashed together with a furious bang, creating a new black hole in the process. This disturbance in the cosmos caused space-time to stretch, co…
A fluffy cluster of stars spilling across the sky may have a secret hidden in its heart: a swarm of over 100 stellar-mass black holes. If this finding can be validated, it will explain how the cluster came to be the way it is - with its …
In three years, the “ Ƅlack hole мerger ,” a rare astronoмical occurrence, will take place. A single Ƅlack hole will Ƅe created when two extreмely large Ƅlack holes мeet and мerge. Due to the fact that the point of conʋergence will Ƅe ʋisiƄle to te…
