Detection of an Echo Emitted by Our Galaxy's Black Hole 200 Years Ago

An international team of scientists has discovered that Sagittarius A* (Sgr A*), the supermassive black hole at the centre of the Milky Way, emerged from a long period of dormancy some 200 years ago. The team, led by Frédéric Marin, a CNRS researcher at the Astronomical Strasbourg Observatory ...

Never-Before-Seen Way to Annihilate a Star

Astronomers studying a powerful gamma-ray burst, may have detected a never-before-seen way to destroy a star. Unlike most GRBs, which are caused by exploding massive stars or the chance mergers of neutron stars, astronomers have concluded that this GRB came instead from the collision of stars or ...

Weigh a Quasar's Galaxy With Precision

Scientists have managed to weigh -- more precisely than any other technique -- a galaxy hosting a quasar, thanks to the fact that it acts as a gravitational lens. Detection of strong gravitational lensing quasars is expected to multiply with the launch of Euclid this ...

What Made the Brightest Cosmic Explosion of All Time So Exceptional?

Last year, telescopes around the world registered the brightest cosmic explosion of all time. Astrophysicists can now explain what made it so ...

Astronomers Detect 'Nearby' Black Hole Devouring a Star

Astronomers have discovered a new 'tidal disruption event,' in which the center of a galaxy lights up as its supermassive black hole rips apart a passing star. The outburst is the closest ...

Most Massive Touching Stars Ever Found Will Eventually Collide as Black Holes

A new study looked at a known binary star (two stars orbiting around a mutual center of gravity), analyzing starlight obtained from a range of ground- and space-based telescopes. The researchers ...

Direct Image of a Black Hole Expelling a Powerful Jet

Astronomers have observed, in one image, the shadow of the black hole at the center of the galaxy Messier 87 (M87) and the powerful jet expelled from it. Thanks to this new image, astronomers can ...

Astronomers Solve the 60-Year Mystery of Quasars -- The Most Powerful Objects in the Universe

Scientists have unlocked one of the biggest mysteries of quasars -- the brightest, most powerful objects in the Universe -- by discovering that they are ignited by galaxies ...

Medium-Sized Black Holes Eat Stars Like Messy Toddlers

In new 3D computer simulations, astrophysicists modeled black holes of varying masses and then hurled stars (about the size of our sun) past them to see what might happen. If they exist, ...

Could This Copycat Black Hole Be a New Type of Star?

It looks like a black hole and bends light like a black hole, but it could actually be a new type of star. Though the mysterious object is a hypothetical mathematical construction, new simulations by ...

A Sharper Look at the M87 Black Hole

The iconic image of the supermassive black hole at the center of M87 has gotten its first official makeover based on a new machine learning technique called PRIMO. The team used the data achieved the ...

M87 in 3D: New View of Galaxy Helps Pin Down Mass of the Black Hole at Its Core

From Earth, giant elliptical galaxies resemble highly symmetric blobs, but what's their real 3D structure? Astronomers have assembled one of the first 3D views of a giant elliptical galaxy, M87, ...

Scientists Map Gusty Winds in a Far-Off Neutron Star System

Astronomers have mapped the 'disk winds' associated with the accretion disk around Hercules X-1, a system in which a neutron star is drawing material away from a sun-like star. The findings ...

Hubble Sees Possible Runaway Black Hole Creating a Trail of Stars

There's an invisible monster on the loose, barreling through intergalactic space so fast that if it were in our solar system, it could travel from Earth to the Moon in 14 minutes. This ...

Hubble Unexpectedly Finds Double Quasar in Distant Universe

The early universe was a rambunctious place where galaxies often bumped into each other and even merged together. Using NASA's Hubble Space Telescope and other space and ground-based ...


Brightest Gamma-Ray Burst Ever Observed Reveals New Mysteries of Cosmic Explosions

Scientists believe the gamma-ray emission, which lasted over 300 seconds, is the birth cry of a black hole, formed as the core of a massive and rapidly spinning star collapses under its own ...

Scientists Find a Common Thread Linking Subatomic Color Glass Condensate and Massive Black Holes

Atomic nuclei accelerated close to the speed of light become dense walls of gluons known as color glass condensate (CGC). Recent analysis shows that CGC shares features with black holes, enormous ...

Baby Star Near the Black Hole in the Middle of Our Milky Way: It Exists After All

Scientists have detected the heaviest and youngest infant star ever discovered close to the black hole at the center of our Galaxy. They also identified the region where this 'impossible ...

A Mysterious Object Is Being Dragged Into the Supermassive Black Hole at the Milky Way's Center

An object near the supermassive black hole at the center of the Milky Way galaxy has drawn the interest of scientists because it has evolved dramatically in a relatively short time. A new study ...

New Discovery Sheds Light on Very Early Supermassive Black Holes

Astronomers have discovered a rapidly growing black hole in one of the most extreme galaxies known in the very early Universe. The discovery of the galaxy and the black hole at its center provides ...

Physicists Create New Model of Ringing Black Holes

A new analysis has modeled black hole collisions in more detail and revealed so-called nonlinear effects within gravitational waves. Nonlinear effects happen 'when waves on the beach crest and ...

Tadpole Playing Around Black Hole

A peculiar cloud of gas, nicknamed the Tadpole due to its shape, appears to be revolving around a space devoid of any bright objects. This suggests that the Tadpole is orbiting a dark object, most ...

Massive Fuel-Hungry Black Holes Feed Off Intergalactic Gas

Research has revealed how supermassive black holes (SMBHs) are feeding off gas clouds which reach them by traveling hundreds of thousands of light years from one galaxy to ...

A Star's Unexpected Survival

Hundreds of millions of light-years away in a distant galaxy, a star orbiting a supermassive black hole is being violently ripped apart under the black hole's immense gravitational pull. As the ...
