ESA’s Euclid spots 31 ancient quasars, including the oldest yet, revealing the universe’s first 670 million years. The European Space Agency’s Euclid telescope has uncovered a set of 31 quasars that formed when the cosmos was only about 670 million...

pipeline has sifted through the Dark Energy Spectroscopic Instrument (DESI) catalog and identified seven new quasars that may also serve as strong gravitational lenses. If follow‑up observations confirm their status, the discovery could roughly double...

Euclid discovers 31 ancient quasars, including two from 670 million years after the Big Bang, shedding light on early black holes and galaxy formation. The ESA Euclid mission has added 31 previously unknown quasars to the cosmic record, among them two...

holes traveling across the universe for millions of years. A fresh analysis suggests that the dusty shroud surrounding quasars could serve as a beacon for identifying runaway supermassive black holes, the massive remnants that may be expelled from their...

Telescope (JWST) has forced a significant reclassification of two distant cosmic objects previously identified as faint quasars. Researchers have determined that these entities, which date back to the first billion years of the universe, are not powered...

emission line model posterior is plotted in orange (Methods). Credit: Nature The discovery tackles a long‑standing puzzle: quasars identified at very early cosmic times host black holes with masses of millions to billions of solar masses, despite the...

astronomical data strengthens the case that these objects represent the foundational, rapid growth phase of the first quasars. While these findings offer a compelling framework, the researchers note that further study is required to understand the...

probe its expansion history. DESI’s spectroscopic campaign, which has already measured more than 47 million galaxies and quasars, relies on the precise positional data supplied by the imaging survey to pinpoint objects for follow‑up observations. How...

sky to track asteroids and near-Earth objects. However, its infrared sensors also captured the fluctuating light of distant quasars, supernovae, and eclipsing binary star systems. The challenge, according to Kirkpatrick, was the sheer volume of data,...

has historically been the primary obstacle for researchers. To confirm the origin of the signal, the team utilized distant quasars as stable reference points. By mapping the MeerKAT observations against these celestial anchors, the researchers were able...

DESI data uncovers chemical fingerprints of shattered exoplanets embedded in polluted white dwarf stars. A new analysis of data from the Dark Energy Spectroscopic Instrument (DESI) provides some of the most compelling evidence to date that dying stars...

A hidden galaxy uncovered in JWST data highlights both the telescope’s discovery power and the measurement challenges within its growing public archive. Analysis of public data from the James Webb Space Telescope has revealed a highly stretched galaxy...

Astronomers have discovered a 202,000-light-year stellar wake, suggesting a violent cosmic collision may have ejected a supermassive black hole into space. Astronomers have traced the origin of a rogue supermassive black hole, identified as RBH-1,...

A record-breaking blazar observation has shed new light on ancient black hole activity and the universe’s mysterious hidden radiation field. Astronomers have achieved a landmark breakthrough in high-energy astrophysics, detecting the most distant...

New observations from DESI and LOFAR reveal supermassive black holes leave glowing trails of ionized gas that extend far beyond their host galaxies. Supermassive black holes are known to exert influence far beyond the galactic centers they occupy, yet...
