Astronomers have performed a comprehensive chemical study of a Galactic globular cluster known as Terzan 6. Results of the study, presented in a research paper published June 11 on the pre-print server arXiv, could advance ...

Using the James Webb Space Telescope (JWST), astronomers from the Space Telescope Science Institute (STScI) have discovered a new supernova. Designated SN 2023adsy, the newfound stellar explosion is the most distant Type ...

An international team of astronomers reports the discovery of a new Earth-sized exoplanet that orbits an ultracool dwarf star located just 54.6 light years away. The newfound alien world, designated SPECULOOS-3 b, is slightly ...

Using the Very Large Telescope (VLT) in Chile, astronomers have observed the halo of a nearby giant elliptical galaxy known as Centaurus A. Results of the observational campaign, published June 1 on the pre-print server arXiv, ...

Chinese astronomers report the discovery of a new high-velocity star about 4,200 light years away. The newfound star, designated J0731+3717, turned out to be ejected from the globular cluster Messier 15 by an intermediate-mass ...

Using the Neutron Star Interior Composition Explorer (NICER) onboard the International Space Station, astronomers have observed a distant X-ray binary known as EXO 2030+375. The observational campaign allowed them to explore ...

Astronomers from New Mexico State University (NMSU) and elsewhere report the discovery of a new galaxy of a rare class, dubbed "green bean." The finding, made with the Karl G. Jansky Very Large Array (VLA), was presented ...

Using the Atacama Large Millimeter/sub-millimeter Array (ALMA), an international team of astronomers has performed high-resolution observations of a nearby galaxy known as NGC 613. Results of the observational campaign, published ...

Using the Five-Hundred-meter Aperture Spherical radio Telescope (FAST), astronomers from the Guizhou University in China and elsewhere have discovered eight new millisecond pulsars in the globular cluster NGC 6517. The finding ...

An international team of astronomers has performed follow-up observations of a nearby alien world known as TOI-1685 b. Results of the observations, published May 21 on the pre-print server arXiv, indicate that TOI-1685 b ...

Astronomers from the Stanford University in California have performed joint X-ray and optical observations of a massive "spider" pulsar designated PSR J2215+5135. Results of the observational campaign, presented in a paper ...

Using the Very Long Baseline Array (VLBA) and the Long Baseline Array (LBA), astronomers have observed a black hole low-mass X-ray binary known as Swift J1727.8-1613. As a result, they found that the system hosts a highly ...

Using ESA's Gaia satellite and the MMT Observatory, astronomers have investigated a peculiar stream of stars in our galaxy named Theia 456. Results of the study, published May 21 on the pre-print server arXiv, deliver important ...

By analyzing the data from NASA's Chandra X-ray observatory, astronomers from India and South Africa have investigated a massive galaxy cluster known as Abell 2566. They detected sloshing cold fronts in the intracluster medium ...

Using the National Astronomical Observatory (OAN) in Mexico, astronomers have observed an open cluster known as NGC 1513. Results of the observations, presented in a paper published May 16 on the pre-print server arXiv, yield ...
