We tuned in to a cosmic background hum, JWST upended our ideas about the early universe, and the new Moon race heated up.

The James Webb Space Telescope has detected the oldest black hole ever seen, feeding voraciously about 400 million years after the Big Bang.

Scientists have reported the first evidence that our Earth and the universe around us are awash in a background of spacetime undulations called gravitational waves. The waves oscillate very slowly over years and even decades and are thought to originate primarily from pairs of supermassive black hol

LIGO confirmed the existence of gravitational waves in 2015, detecting one-time perturbations of spacetime from the merger of large black holes. There should be a background of gravitational waves permeating space due to other cataclysmic events in the cosmos, perhaps dating from the Big Bang. The NANOGrav consortium reports evidence from pulsar timing arrays that space is filled with such waves. Simulations suggest the cosmic gravitational wave background is likely caused by the merger of hundreds of thousands of supermassive black holes over the history of the universe.

A collaboration including Cornell astrophysicists has found the first evidence of low-frequency gravitational waves believed to be generated by merging pairs of supermassive black holes.
