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 ...

Using NASA's Chandra spacecraft and ESA's XMM-Newton satellite, astronomers have investigated the galaxy NGC 7793, searching for supernova remnants (SNRs). As a result, they discovered four new X-ray SNRs in this galaxy. ...

Using the Hard X-ray Modulation Telescope (HXMT), Chinese astronomers have observed an X-ray binary system designated IGR J19294+1816. As a result, they discovered multiple X-ray quasi-periodic oscillations in this source. ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected three new hot Jupiter exoplanets orbiting three distant K dwarf stars. The finding was reported in a research paper ...

Russian astronomers from the Sternberg Astronomical Institute (SAI) have analyzed long-term observational data of a peculiar microquasar designated SS 433. Results of the new study, published May 13 in the Physics-Uspekhi ...

Astronomers from the Aryabhatta Research Institute of Observational Sciences (ARIES) in India and elsewhere have employed the Devasthal Fast Optical Telescope (DFOT) to conduct long-term photometric observations of an open ...

Astronomers have conducted very long baseline Interferometry (VLBI) observations of an active galaxy known as Markarian 110. As a result, they detected a relativistic jet in this galaxy. The finding was reported in a research ...

Using the Low Frequency Array (LOFAR), European astronomers have investigated a galaxy cluster designated CIZA J2242.8+5301, dubbed the Sausage cluster. The observations conducted at very low radio frequencies provide more ...
