By conducting a blind search for large amplitude mid-infrared variables in the Wide Infrared Sky Explorer (WISE) archive, Chinese astronomers have serendipitously discovered a giant mid-infrared outburst from a distant young ...

Astronomers have reported the discovery of a new galaxy using the James Webb Space Telescope (JWST) as part of the JWST COSMOS-Web survey. The newfound object, designated JWST-ER1 is a massive and compact quiescent galaxy. ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new exoplanet orbiting a distant star. The newfound alien world, designated TOI-1420 b, has an exceptionally low ...

Using the James Webb Space Telescope (JWST), an international team of astronomers has observed the galaxy cluster PLCK G165.7+67.0. The observational campaign resulted in the detection of a new Type I supernova. The finding ...

Using the Neutron star Interior Composition Explorer (NICER) onboard the International Space Station (ISS), European astronomers have performed spectral analysis of a low-mass X-ray binary known as XTE J1810–189. Results ...

Using data from ESA's Gaia satellite, astronomers from the Istanbul University have inspected a Galactic open cluster known as NGC 2509. Results of the study, published September 10 on the pre-print server arXiv, deliver ...

An international team of astronomers reports the detection of a new faint ultra-diffuse dwarf galaxy as part of a systematic wide-area search for faint dwarf galaxies using the Dark Energy Survey (DES). The newfound object, ...

Using various spacecraft, astronomers from India and Chile have performed X-ray observations of a peculiar intermediate polar known as TX Columbae. Results of the observational campaign, published September 7 on the pre-print ...

Using the Large Phased Array (LPA) radio telescope of the Lebedev Physical Institute (LPI) in Pushchino, Russia, astronomers have detected two new rotating radio transients (RRATS). The finding is reported in a research paper ...

Astronomers from the University of Alabama in Huntsville have investigated the galaxy cluster Abell 3558 using ESA's XMM-Newton spacecraft. In their results, they detected two large-scale sloshing cold fronts in the outskirts ...

Astronomers from the University of Maryland and the Michigan Technological University, have inspected a mysterious ultra-high energy gamma-ray source known as LHAASO J2108+5157. Results of the study, published August 31 on ...

Using the Nuclear Spectroscopic Telescope Array (NuSTAR) spacecraft and the Neutron star Interior Composition Explorer (NICER) instrument onboard the International Space Station, astronomers have inspected an ultracompact ...

Astronomers report the discovery of a new massive and quiescent galaxy at a high redshift. The galaxy, which received designation COSMOS-1047519, was detected using the Keck I telescope. The finding was detailed in a paper ...

By analyzing the data from the Dark Energy Camera Legacy Survey (DECaLS), astronomers from the Christ University in Bangalore, India, have serendipitously discovered a new ring galaxy, which received designation DES J024008.08-551047.5 ...

Using NASA's Kepler and ESA's Gaia spacecraft, an international team of astronomers has conducted an astroseismic investigation of six giant stars in the open cluster NGC 6866. The study, presented August 24 on the pre-print ...
