A research team led by Professor Woong-bae Zee at Sejong University has uncovered compelling evidence that the distinctive warped shapes of many disk galaxies are closely tied to both their surrounding satellite systems and the […]

A team of astronomers including George Washington University physics Ph.D. student Eliza Neights recorded an extraordinary cosmic outburst this July which likely heralds a new kind of stellar explosion. With a flood of data from […]

Gamma-ray bursts (GRB) are some of the most perplexing phenomena in nature. Even though astronomers have detected about 15,000 of them, with a new one each day, they’re still mysterious. They’re the most luminous, energetic […]

An international team of researchers has used knowledge of historical geography to reexamine the earliest datable total solar eclipse record known to the scientific community, enabling accurate measurements of Earth’s variable rotation speed from 709 […]

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 […]
