Using the James Webb Space Telescope (JWST), astronomers have discovered a new red galaxy at a redshift of approximately 11.45. The newfound galaxy, which received designation EGS-z11-R0, turns out to be the most distant red galaxy detected to date. The discovery was detailed in a paper published March 18 on the arXiv pre-print server.

Pulsars are ultra-dense, rapidly spinning, and highly magnetized remnants of dead stars. They act like cosmic lighthouses, sending out regular pulses of radio waves and sometimes gamma rays in beams that sweep across the sky. A special class called millisecond pulsars spins hundreds of times per second and is among the most precise clocks in […]

More than half a century after the groundbreaking Apollo program’s last crewed flight to the moon, three men and one woman are preparing for a lunar journey set to turn a new page in American space exploration.

Astronomers at the University of Warwick have validated over 100 exoplanets, including 31 newly detected planets, using a new artificial intelligence tool applied to data from NASA’s Transiting Exoplanet Survey Satellite (TESS), a space mission that monitors the sky for the subtle dimming of starlight caused when planets pass in front of their host stars. […]

Astronomers have an answer for a long-running mystery in astrophysics: why is the growth of supermassive black holes so much lower today than in the past? A study using NASA’s Chandra X-ray Observatory and other X-ray telescopes found that supermassive black holes are unable to consume material as rapidly as they did in the distant […]

Astronomers have observed two planets forming in the disk around a young star named WISPIT 2. Having previously detected one planet, the team has now employed European Southern Observatory (ESO) telescopes to confirm the presence of another. These observations, and the unique structure of the disk around the star, indicate that the WISPIT 2 system […]
