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...

signature and the accompanying light from the coalescence of two neutron stars. This dual observation pinpointed the host galaxy, making the event especially valuable for cosmological calculations. Visualization of the GW170817 afterglow based on...

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...

Hubble observations reveal that powerful galactic winds from exploding stars may unexpectedly trap radiation, hindering the early universe’s reionization. New research using the Hubble Space Telescope suggests that the mechanisms allowing radiation to...

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...

its successes in matching overall source counts and angular sizes, the model highlights a notable tension regarding host galaxy redshifts. While the simulation predicts relatively nearby rings with a median redshift below 0.1, the putative host galaxies...

NASA’s Roman Space Telescope moves into final Falcon Heavy integration, nine months early, aiming for an August launch. NASA’s Nancy Grace Roman Space Telescope is moving through a critical stage of its launch campaign at Kennedy Space Center, as...

A mysterious chemical discovery within a giant cloud near the Milky Way’s core is challenging current theories about how distant regions of space evolve. Astronomers have uncovered a massive, chemically diverse gas cloud near the galactic center that...

Astronomers have discovered a mysterious new world orbiting a distant star, revealing a unique planetary system that defies everything we know about space. Astronomers have identified HD 176071 b, a remarkable water-rich exoplanet locked in a perilous,...

A mysterious rocky exoplanet once thought to break the laws of physics may be an illusion, as new data challenges our understanding of its true size. The existence of “mega-Earths”—massive, dense rocky worlds that seem to defy standard planetary...

Rubin Observatory’s new camera reveals a deep‑field image of over 500,000 galaxies, offering an unprecedented view of the cosmos. Vera C. Rubin Observatory has released its inaugural ultra‑deep exposure captured by the 3.2‑gigapixel camera, unveiling a...
