The First-Ever Close-Up of a Black Hole

The first-ever image of a black hole was released Wednesday by a consortium of researchers, showing the "black hole at the center of galaxy M87, outlined by emission from hot gas swirling around it under the influence of strong gravity near its event horizon."

You're looking at the brand-new, first-ever close-up picture of a black hole. This image of the black hole M87 at the center of the Virgo A galaxy is the result of an international, 2-year-long effort to zoom in on the singularity. It reveals. for the first time, the contours of

Now We Know That Dark Matter Isn’t Primordial Black Holes

For over fifty years, scientists have theorized that roughly 85% of matter in the Universe’s is made up of a mysterious, invisible mass. Since then, multiple observation campaigns have indirectly witnessed the effects that this “Dark Matter” has on the Universe. Unfortunately, all attempts to detect it so far have

Gamma Ray Telescopes could Detect Starships Powered by Black Hole

In the course of looking for possible signs of Extra-Terrestrial Intelligence (ETI), scientists have had to do some really outside-of-the-box thinking. Since it is a foregone conclusion that many ETIs would be older and more technologically advanced than humanity, those engaged in the Search for Extra-Terrestrial Intelligence (SETI) have to

Scientists detect biggest known black-hole collision

An international team of scientists have detected ripples in space and time, known as gravitational waves, from the biggest known black-hole collision that formed a new black hole about 80 times larger than the Sun – and from another three black-hole mergers.The Australian National University (ANU) is playing a lead

Black Holes Ruled Out As Universe’s Missing Dark Matter

For one brief shining moment after the 2015 detection of gravitational waves from colliding black holes, astronomers held out hope that the universe’s mysterious dark matter might consist of a plenitude of black holes sprinkled throughout the universe. UC Berkeley physicists have dashed those hopes.Based on a statistical analysis of

Black Holes Might Temporarily Bring Dead Stars Back to Life

What happens when a dead star meets a black hole? The answer appears to be a brief zombie awakening, according to a new paper. Let me explain.A team of scientists was interested in how white dwarfs—small, dense objects thought to form when bigger stars run out of fuel—interact around black
