NASA’s Chandra Observatory reveals 16 stunning new galaxy images, showcasing the powerful cosmic forces currently shaping our universe. NASA has unveiled a stunning new collection of 16 galactic portraits, offering a multi-wavelength perspective on the...

our Milky Way – © ESA During such mergers, gas clouds can interact and the evolving gravitational field can reshape the host galaxy’s structure and tilt its disc. In Batrakov’s Auriga‑based simulations, systems that experienced Gaia‑Sausage‑like mergers...

± 0.5. In plain terms, these correspond to roughly 80 million, 0.6 million, and 2 million solar masses, respectively. The host galaxy’s stellar mass is approximated at 1.3 billion M☉, meaning the black holes together constitute a substantial portion of...

A new computer simulation of a Milky Way‑like galaxy reveals an unexpected phenomenon deep within its core, reshaping our view of galactic centers. A recent high‑resolution simulation of a Milky Way‑type galaxy demonstrates that the dense nuclear star...

have recorded a brilliant outburst that marks a supermassive black hole shredding a star far from the center of its host galaxy. The detection offers solid proof that these colossal objects can wander through galactic outskirts rather than staying fixed...

spectroscopy. By breaking down the light into specific wavelengths, scientists hope to differentiate the light of the host galaxy from that of the central engine and analyze the chemical composition and physical states of the surrounding gas. Finding...

spot, they typically trace only a minor fraction of the total wind mass and often blend into the bright background of the host galaxy. To capture the dominant mass reservoir of these winds, astronomers look to neutral gas tracers. In the local Universe,...

roam through space. Astronomers have uncovered a massive black hole lurking 3,500 light-years away from the center of its host galaxy, a discovery made possible only after the gravity of the hidden object shredded a passing star. The finding, documented...

Observations of the distant system GHZ8 reveal an interacting pair of young galaxies with extreme star-formation rates and high escaping radiation. Astronomers using the James Webb Space Telescope have spotted an unexpected cosmic duo shining brightly...

NASA’s Hubble Space Telescope has captured a stunning new image of a distant galaxy, revealing fascinating details that offer a closer look at our universe. The Hubble Space Telescope has returned a striking new portrait of NGC 1827, an intermediate...

axes of the two black holes provided the necessary gravitational recoil to slingshot the merged object out of its host galaxy. “I was initially surprised by how extreme this sounds, but then I realized it probably had to be the case in order to have...

that a pair of colliding ultramassive black holes is carving out the emptiness as they spiral toward each other. The host galaxy sits at the core of the Abell 402 cluster, an assemblage located about 4 billion light‑years from Earth according to Sky &...

black hole, heating up into a radiant accretion disk that outshines the combined light of all the stars in the host galaxy. Detecting such objects from the first billion years of cosmic history has long been hampered by their extreme distance and the...

we observe today. Follow‑up observations of one of the newly identified quasars have already revealed a dusty, gas‑rich host galaxy undergoing vigorous star formation, suggesting that massive black‑hole growth and intense galaxy assembly occurred in...

Researchers deploy probabilistic models to decode the complex structural signatures of disturbed galaxies across millions of wide-field images. Galaxies constantly evolve in response to their surrounding environments, changing their shapes as they...

known as precession, is necessary to produce a recoil kick powerful enough to eject the black hole from its host galaxy. “The two black holes had to be spinning fast, and their spins had to be misaligned,” explained lead author Tousif Islam of the Kavli...

These puzzling, crimson specks in the early universe appeared to hold impossibly large black holes. New research suggests they are actually young giants swaddled in dense, light-scattering cocoons that have misled astronomers for years. When the James...

Astronomers have uncovered a rare, decades-long flare from the Perseus Cluster’s central black hole, finally solving a mystery hidden in years of data. Astronomers tracking the behavior of a supermassive black hole at the heart of the Perseus Cluster...

concerns to be unfounded. Led by Phil Wiseman of the University of Southampton, the researchers demonstrated that once host galaxy characteristics are properly accounted for, the data continues to confirm that the universe is speeding up in its...

JWST observations of a mysterious red dot reveal that dense gas around a hidden engine, not ancient stars, creates the strongest Balmer break ever seen. Astronomers hunting the early Universe with JWST have repeatedly turned up compact, very red...
