Astronomers have discovered the closest known black hole to Earth, which is 1,600 light-years away and is 10 times larger than the sun, according to a new study published on Nov. 4. The stellar-mass black hole, dubbed “Gaia BH1,” is located in the constellation Ophiuchus, according to the U.S.-based National Optical-Infrared Astronomy Research Laboratory (NOIRLab)….
Astronomers Discover Closest Black Hole to Earth, Say It’s 10 Times Bigger Than the Sun
Scientists Find an Exotic Black Hole Deemed a ‘Needle in a Haystack’
WASHINGTON—Astronomers have spotted in a galaxy adjacent to our Milky Way what they are calling a cosmic “needle in a haystack”—a black hole that not only is classified as dormant but appears to have been born without the explosion of a dying star. Researchers said on Monday this one differs from all other known black…
Astronomers Capture 1st Image of Milky Way’s Huge Black Hole
WASHINGTON—The world got a look Thursday at the first wild but fuzzy image of the supermassive black hole at the center of our own Milky Way galaxy, with astronomers calling it a “gentle giant” on a near-starvation diet. Astronomers believe nearly all galaxies, including our own, have these giant black holes at their center, where…
Black Hole Hunters Cast Gaze at Center of the Milky Way Galaxy
WASHINGTON—Residing at the center of our spiral-shaped Milky Way galaxy is a beast—a supermassive black hole possessing 4 million times the mass of our sun and consuming any material including gas, dust, and stars straying within its immense gravitational pull. Scientists have been using the Event Horizon Telescope (EHT), a global network of observatories working…
Astronomers Spot Black Hole ‘Giving Birth’ to New Stars in ‘Stellar Nursery’ Galaxy—Instead of Destroying Them
Black holes—like monstrous, cosmic super villains—habitually wreak havoc in space, tearing stars to pieces, consuming anything that comes too close, even preventing light from escaping their clutches. The role black holes play on the universal stage is mostly a destructive one. But foiling this villainous depiction, researchers recently discovered a cluster of newly forming stars…
Hubble Space Telescope Captures Mysterious ‘Dead Galaxies’ 11 Billion Light-Years Away
Extraordinary images captured by Hubble Space Telescope and ALMA observatory—utilizing unique natural gravitational lensing—revealed a remarkable phenomenon which occurred in space 11 billion years ago. Early in the life of the universe, when it was just 3 billion years old and stars were forming abundantly, a cluster of galaxies mysteriously died out and stopped producing stars for some unknown…
Cosmic Gulp: Astronomers See Black Hole Swallow Neutron Star
Talk about a heavy snack. For the first time, astronomers have witnessed a black hole swallowing a neutron star, the most dense object in the universe—all in a split-second gulp. Ten days later they saw the same thing, on the other side of the universe. In both cases, a neutron star—a teaspoon of which would…
Exceptional Cosmic Explosion Challenges Established Theory of Gamma-Ray Bursts
Scientists have obtained the best view so far of the most powerful type of cosmic explosion, which happened this time in our cosmological “backyard.” Using the High Energy Stereoscopic System (H.E.S.S.), the research team recorded the most energetic radiation and longest gamma-ray afterglow of a gamma-ray burst (GRB) ever observed. The results challenged the established…
First Polarized Image of Black Hole Hints at Its Magnetic Field Structure
Astronomers from the Event Horizon Telescope (EHT) collaboration have produced the first-ever polarized picture of a black hole. In 2019, the same team obtained the first-ever image of a black hole. Both images were taken of the same object in the center of the M87 galaxy. The 2019 image, which shows a bright ring-like structure…
Astronomers Discover By Far the Most Distant Known ‘Radio-Loud’ Quasar
Quasars are among the most extreme astrophysical objects in our universe. They contain supermassive black holes and lie at the centers of galaxies, where they quickly consume nearby materials and emit enormous amounts of energy. A small percentage of quasars also drive powerful radio jets, which can travel at nearly the speed of light. Now…
