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, ...

Using the Very Large Array (VLA), astronomers have performed radio observations of a galaxy cluster Abell 2744, nicknamed Pandora's Cluster. As a result, they obtained the deepest high-resolution radio image of this cluster, ...

Using the Australia Telescope Compact Array (ATCA), astronomers have performed large-scale radio observations of a star-forming region known as the Chamaeleon cloud complex. The observational campaign, which detected five ...

An international team of astronomers has employed various satellites and ground-based telescopes to perform multiwavelength observations of a supernova remnant known as SNR J0450.4−7050. Results of the observational campaign, ...

Using the Magellan Telescopes at Las Campanas Observatory in Chile, astronomers have performed a chemical study of a globular cluster known as ESO 280-SC06. As a result, they found that ESO 280-SC06 is a tidally disrupted ...

Chinese astronomers have employed NASA's Transiting Exoplanet Survey Satellite (TESS) to observe an eclipsing binary of the Algol-type, designated V455 Car. Results of the observational campaign are published in the journal ...

Using the James Webb Space Telescope (JWST), astronomers from Canada and Switzerland have discovered a new galaxy, which received designation COSMOS2020-635829. The newfound object appears to undergo a ram pressure stripping ...

An international team of astronomers reports the detection of a peculiar merger of two similar ring galaxies that morphologically resemble an owl's face. The discovery of this galaxy merger, dubbed the "Cosmic Owl," is presented ...

By analyzing the data from the DESI Legacy Imaging Survey, Chinese astronomers have investigated a globular cluster known as NGC 5634. Results of the new study, published June 5 on the arXiv pre-print server, provide more ...
