The Mid-Infrared Instrument (MIRI) on NASA’s James Webb Space Telescope captured glowing cosmic dust heated by very young massive stars in unprecedented detail in this image of the Sagittarius B2 (Sgr B2) molecular cloud released […]

Astronomers have long debated the role of galaxy mergers in powering active supermassive black holes. Now an unprecedented dataset of a million galaxies from the Euclid telescope provides evidence that mergers play a dominant role […]

On 2 December 1995, the ESA/NASA Solar and Heliospheric Observatory (SOHO) blasted into space—on what was supposed to be a two-year mission.This post was originally published on this site

Seventy light-years from Earth, a star called Kappa Tucanae A harbors one of astronomy’s most perplexing mysteries: dust so hot it glows at more than 1,000 degrees Fahrenheit, existing impossibly close to its host star, […]

A spiral galaxy, shaped much like our Milky Way, has been found in an era when astronomers believed such well-formed galaxies could not yet exist. Two astronomers from India have identified a remarkably mature galaxy […]

Using ESA’s XMM-Newton satellite, astronomers from Stanford University and elsewhere have conducted deep X-ray observations of a nearby galaxy known as NGC 3221. The new observational campaign detected a faint active galactic nucleus (AGN) in […]

Using images from the James Webb Space Telescope (Webb), an international research team including Western’s Stanimir Metchev has discovered new answers to explain how some brown dwarfs form giant dust storms, contradicting previous assumptions. These […]

New balloon-mounted space radiation probes developed by the Surrey Space Center at the University of Surrey have captured their first measurements of a major solar storm, confirming the research team’s model, which indicates the flare […]

Ask someone on Earth for the time and they can give you an exact answer, thanks to our planet’s intricate timekeeping system, built with atomic clocks, GPS satellites and high-speed telecommunications networks.This post was originally […]

Nearly 4.5 million years ago, two large, hot stars brushed tantalizingly close to Earth’s sun. They left behind a trace in the clouds of gas and dust that swirl just beyond our solar system—almost like […]
