Using the MeerKAT radio telescope, an international team of astronomers has performed observations of a galaxy cluster designated SPT-CLJ2337−5942. The observational campaign revealed the presence of an ultra-steep spectrum ...

Using the James Webb Space Telescope (JWST), astronomers have detected what appears to be a faint and small star-forming complex. The discovery of the new complex, which received the designation LAP2, is detailed in a research ...

Astronomers from Ruhr University Bochum in Germany and elsewhere have conducted radio spectropolarimetric observations of a recently identified odd radio circle designated ORC J0356–4216. Results of the observational campaign, ...

Using radial velocity measurements, an international team of astronomers has identified a second planet orbiting a nearby M-dwarf star known as Gliese 536. The newfound alien world turns out to be at least a few times more ...

An international team of astronomers reports the discovery of a new pre-main-sequence eclipsing binary system. The newfound binary, designated MML 48, consists of two young low-mass stars. The finding will be published in ...

Using the Hubble Space Telescope (HST), Italian astronomers have observed five blue straggler stars in the globular cluster 47 Tucanae. Their results show that one of these stars has a white dwarf companion. The discovery ...

Using ESA's INTEGRAL spacecraft, astronomers have detected exceptionally bright X-ray flares from the Cygnus X-1 X-ray binary system. This is the first time that such strong flaring activity has been observed in this system ...

Using the upgraded Giant Metrewave Radio Telescope (uGMRT), astronomers have performed radio observations of the Ophiuchus galaxy cluster. Results of the observations, published August 26 in The Astrophysical Journal, deliver ...

Astronomers from Yonsei University in Seoul, South Korea, and elsewhere report the discovery of a new isolated early-type dwarf galaxy, which appears to have run away from the group environment. The finding is detailed in ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered two rocky exoplanets orbiting a nearby K-type star, known as TOI-2322. The newfound alien worlds are comparable in size to Earth and have ...

Astronomers have performed radio observations of WTP 14adeqka—a tidal disruption event discovered a decade ago. Results of the observational campaign, published August 22 on the pre-print server arXiv, provide crucial insights ...

By analyzing the available optical spectroscopic data, astronomers have investigated a nearby planetary nebula designated IC 418, also known as the Spirograph Nebula. Results of the study, published August 20 in The Astrophysical ...

By analyzing the data from the American Association of Variable Star Observers (AAVSO) international database and the Small and Medium Aperture Telescope System (SMARTS), astronomers have inspected a nova in the Large Magellanic ...

By analyzing the data from the MeerKAT International Giga-Hertz Tiered Extragalactic Exploration (MIGHTEE-HI) survey, astronomers have discovered a new rotating galaxy filament. The newfound filament is about 5.5 million ...

Using the James Webb Space Telescope (JWST), astronomers have conducted spectroscopic observations of a high-redshift galaxy known as XMM-VID1-2075. Results of the observational campaign, presented August 14 on the pre-print ...
