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...

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...

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...

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...

New observations suggest that active supermassive black holes play a key role in shaping star formation across their host galaxies. Active Galactic Nuclei May Foster Rather Than Hinder Star Formation A new investigation into nine nearby galaxies...

relative to their host galaxies. By a redshift of 8, the simulated black holes accounted for approximately 1% of their host galaxy’s stellar mass—an order of magnitude higher than the ratio observed in the modern local universe. This alignment between...

Sixty years of hunting for alien worlds has revealed exoplanets more bizarre than fiction, from iron-raining skies to vast, mysterious water worlds. Six decades after Star Trek first captured the public imagination with depictions of alien worlds,...

archival imaging (see Appendix C). The transient explosion site (red crosshairs) is offset by 3‑4 from the center of the host galaxy (blue cross), corresponding to 2.5 kpc at z = 0.0344.Credit: The Astrophysical Journal Letters Expanding the sample of...

AI sifts through 100k+ distant objects to spot rare quasar lens candidates A machine‑learning pipeline has sifted through the Dark Energy Spectroscopic Instrument (DESI) catalog and identified seven new quasars that may also serve as strong...

Astronomers have discovered a rare exoplanet orbiting in the opposite direction of its host star, challenging everything we know about planetary formation. Astronomers have uncovered a celestial oddity that defies the standard models of planetary...
