Using the James Webb Space Telescope (JWST), an international team of astronomers has observed a distant faint galaxy designated JADES-GS-z14-1. Results of the observational campaign, published July 30 on the arXiv preprint ...

Astronomers from Wuhan University in China have employed the Insight-HXMT satellite to observe a giant outburst that occurred in the X-ray binary RX J0440.9+4431 about three years ago. Results of the observations, presented ...

Chinese astronomers have used NASA's Fermi gamma-ray space telescope to conduct a long-term study of a bright gamma-ray pulsar known as PSR J0007+7303. In their results, they identified more glitching events in this pulsar. ...

An international team of astronomers has employed NASA's Chandra X-ray observatory to perform the most detailed study of a supergiant star known as Wd1-9, which yielded important insights into the properties and nature of ...

An international team of astronomers reports the discovery of a new long-period radio transient, which received the designation ASKAP J144834−685644 (ASKAP J1448−6856 for short). The newfound transient is a crucial addition ...

Using the Hubble Space Telescope (HST), astronomers have observed a nearby ultra-diffuse galaxy designated F8D1. The new observations, presented July 17 on the pre-print server arXiv, deliver important insights into the star ...

A team of astronomers from Rhodes University and elsewhere have investigated a sample of 104 quasars detected with the MeerKAT International GHz Tiered Extragalactic Exploration (MIGHTEE) survey. The new study, published ...

Using the James Webb Space Telescope (JWST), the Hubble Space Telescope (HST) and the Gemini Observatory, European astronomers have observed a nearby cold brown dwarf known as WISE 1738. Results of the observational campaign, ...

Using various telescopes worldwide, an international team of astronomers has observed a tidal disruption event (TDE) known as AT2018hyz, which allowed them to witness a rapid brightening of this source in the radio band.

Using the Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new exoplanet orbiting a nearby star. The newfound alien world, designated TOI-2431 b, is comparable in size to Earth ...

An international team of astronomers has performed multi-band radio observations of diffuse radio emission in a galaxy cluster known as Abell 3558. As a result, the observational campaign detected that the cluster hosts a ...

Using the James Webb Space Telescope (JWST), an international team of astronomers has performed deep and high spectral resolution imaging of a distant protocluster of galaxies, designated A2744-z7p9OD. Results of the new ...

Using the TUBITAK National Observatory and ESA's Gaia satellite, astronomers from the Istanbul University in Turkey and elsewhere have conducted comprehensive observations of two open clusters, namely: Czernik 41 and NGC ...

An international team of astronomers report the discovery of a long-period radio transient, which is unusually circularly polarized and showcases an accelerating spin period. The finding of the new transient, designated CHIME ...

Argentinian astronomers have employed the upgraded Giant Metrewave Radio Telescope (uGMRT) to perform high-resolution radio observations of a nearby spiral galaxy designated NGC 4527. Results of the observational campaign, ...
