Astronomers report the discovery of a rare nova super-remnant surrounding the recurrent nova LMCN 1971-08a in the Large Magellanic Cloud (LMC). This is the first nova super-remnant identified in the LMC. The findings are ...

An international team of astronomers has performed photometric and spectroscopic observations of a compact stellar system around a nearby spiral galaxy known as NGC 7531. Results of the observational campaign, published September ...

Using the James Webb Space Telescope (JWST), astronomers from the University of Florida and elsewhere have performed infrared observations of a star-forming cloud known as Sagittarius B2. Results of the observational campaign, ...

An international team of astronomers has conducted detailed multicolor photometric and spectroscopic observations of SN 2022xlp—a type Iax supernova. Results of the observational campaign, published September 9 on the arXiv ...

An international team of astronomers reports the discovery of a new "spider" millisecond pulsar, which received designation PSR J1544−2555. The finding was presented in a research paper published September 11 on the arXivpre-print ...

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 ...
