Euclid found 31 exceptionally early quasars—including two new record holders
The objects were already blazing when the universe was about 670 million years old, sharpening the puzzle of early black-hole growth.
Black holes, galaxies, exoplanets, missions and the early universe—observation first, speculation labeled.
These hubs combine the newest records with method guidance and live counts from the database.
From quiet stellar-mass companions to the earliest quasars, this hub separates direct measurements from model-dependent mass and growth estimates.

An unusual source 660 million years after the Big Bang fits a proposed rapid-growth configuration, but the interpretation is model-based.
NASA rover observations revealed a broad polygonal pattern whose geometry could preserve clues about ancient fluids and rock alteration.
Ultraviolet observations revealed a trail through the red supergiant’s extended atmosphere, offering indirect evidence for a close companion.
Infrared spectra of the interstellar comet revealed a volatile composition that can be compared with material formed around other stars.
Archival data suggest outgassing torques slowed comet 41P and then pushed its rotation through a stop into the opposite direction.
Spacecraft imaging of Donaldjohanson showed a contact-binary shape and non-simple rotation that record a complicated collision history.
The compact hydrogen cloud appears dominated by dark matter yet contains no detected stars, potentially representing a long-predicted type of object.
Astronomers used small variations in a stellar companion’s timing signal to infer a planet in a configuration difficult to find with standard transit searches.
Bennu’s chemistry expands the inventory of compounds that formed before planets matured. It does not show that life existed on the asteroid.
