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.

Space & Astronomy Preliminary evidence
JWST observations point to a black hole wrapped in dense gas at cosmic dawn
An unusual source 660 million years after the Big Bang fits a proposed rapid-growth configuration, but the interpretation is model-based.

Pristine asteroid samples contain complex nitrogen-rich organic material
Bennu’s chemistry expands the inventory of compounds that formed before planets matured. It does not show that life existed on the asteroid.
