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, ...

Astronomers from Bulgaria and Egypt have performed multi-wavelength observations of a well-known blazar designated S5 0716+714. Results of the observational campaign, published June 23 in the Monthly Notices of the Royal ...

Using NuSTAR and XMM-Newton satellites, astronomers from New York University (NYU) Abu Dhabi have observed a pulsar known as PSR J1930+1852 and its pulsar wind nebula (PWN). Results of the observational campaign, published ...

Astronomers from the Center of Astronomical and Space Education in Moscow report the discovery of a new star, which turned out to be an eclipsing variable binary. The finding of the new star, which received designation Grigoriev ...

Astronomers from the University of Turku in Finland and elsewhere have performed a broadband spectral and timing study of an X-ray binary designated XTE J0111.2−7317, which resulted in the detection of quasi-periodic oscillations ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new super-Earth exoplanet that orbits a nearby M dwarf star. The newfound alien world, designated TOI-1846 b, ...
