A Black Hole can Tear a Neutron Star Apart in Less Than 2 Seconds

Almost seven years ago (September 14th, 2015), researchers at the Laser Interferometer Gravitational-wave Observatory (LIGO) detected gravitational waves (GWs) for the first time. Their results were shared with the world six months later and earned the discovery team the Noble Prize in Physics the following year. Since then, a total of 90 signals have been observed that were created by ...

A Star Came too Close to a Black Hole and was Torn Apart. Surprisingly Little Actually Went In

What happens when a star wanders too close to a supermassive black hole? The obvious story is that it gets sucked in, never to be seen again. Some of its material gets superheated on the way in and that gives off huge amounts of radiation—usually X-rays. That’s not a wrong explanation, just incomplete. There’s more to the story, thanks to ...

Do Supermassive Black Holes Prematurely end Star Formation in Some Galaxies?

Some galaxies, like the Milky Way, have maintained regular star formation for billions of years. Others, like large elliptical galaxies, are “red and dead.” Star formation in those galaxies shut off long ago. Astronomers have long suspected the nefarious influence of supermassive black holes, and new research has found the smoking gun. An international team of astronomers led by Kei ...

Astronomers unveil first image of the Milky Way’s central black hole

The Event Horizon Telescope collaboration unveiled the first image of the super massive black hole at the heart of the Milky Way, showing a ring of blazing, super-heated material just outside the shadow of its event horizon, the gravitational point of no return for anything falling in.

A Nearby Dwarf Galaxy has a Surprisingly Massive Black Hole in its Heart

Since the 1970s, scientists have known that within the cores of most massive galaxies in the Universe, there beats the heart of a Supermassive Black Hole (SMBH). The presence of these giant black holes causes these galaxies to be particularly energetic, to the point where their central regions outshine all the stars in their disks combined – aka. Active Galactic ...

Astronomers Discover an Intermediate-Mass Black Hole as it Destroys a Star

Supermassive black holes (SMBH) reside in the center of galaxies like the Milky Way. They are mind-bogglingly massive, ranging from 1 million to 10 billion solar masses. Their smaller brethren, intermediate-mass black holes (IMBH), ranging between 100 and 100,000 solar masses, are harder to find. Astronomers have spotted an intermediate-mass black hole destroying a star that got too close. They’ve ...
