Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered two sub-Neptune exoplanets orbiting a subgiant star known as TOI-6054. The newfound alien worlds are nearly three ...

Using the MeerKAT telescope in South Africa, an international team of astronomers has detected 26 new Galactic radio transients. Most of them turned out to be rotating radio transients (RRATs). The finding is detailed in ...

Using NASA's Chandra and ESA's XMM-Newton spacecraft, an international team of astronomers have performed X-ray observations of a nearby low-mass galaxy cluster designated PSZ2 G181.06+48.47. The observational campaign, detailed ...

An international team of astronomers reports the discovery of a new compact galaxy group using the Atacama Large Millimeter/submillimeter Array (ALMA). The new group, designated CGG-z4, hosts two optically dark star-forming ...

Using the Cerro Tololo Inter-American Observatory (CTIO), an international team of astronomers have performed deep optical observations of a dwarf galaxy known as NGC 300. As a result, they detected a stellar stream, shells ...

Using the Transiting Exoplanet Survey Satellite (TESS) and the Next Generation Transit Survey (NGTS), an international team of astronomers has discovered a new eclipsing binary system with a relatively low mass and long orbital ...

An international team of astronomers has reported the detection of a new exoplanet orbiting a bright late F-type star. The newfound alien world, designated TOI-6038 A b, is about six times larger and nearly 80 times more ...

An international team of astronomers has conducted multiwavelength observations of a variable star designated Gaia22ayj. Results of the observation campaign indicate that this star is a magnetic accreting white dwarf. The ...

Using the James Webb Space Telescope (JWST), astronomers have characterized the atmosphere of a hot super-Neptune exoplanet designated WASP-166 b. As a result, they found that the atmosphere of this alien world contains water ...

Using NASA's Fermi space telescope, Italian astronomers have observed a radio source known as 3C 216. As a result, they detected increased gamma-ray activity from this source, including a strong outburst. The finding is reported ...

An international team of astronomers have investigated a large Galactic supernova remnant designated G278.94+1.35. Results of the study, published Dec. 30 on the pre-print server arXiv, shed more light on the properties of ...

Using the VLT Survey Telescope (VST), astronomers from Italy and Germany have observed a group of galaxies designated NGC 5018. Results of the observational campaign, published Dec. 23 on the pre-print server arXiv, yield ...

A group of astronomers from numerous institutions have investigated a recently discovered nearby tidal disruption event known as ASASSN-22ci. They detected two luminous flares from this event. The finding was reported in ...

In a recent study, an Italian astronomer has investigated the nature of a binary system known as HD 49798/RX J0648.0–4418. Results of the new research, published Dec. 24 on the preprint server arXiv, yield important insights ...

Using the X-shooter instrument at ESO's Very Large Telescope (VLT), German astronomers have detected three new pre-white dwarfs, which turned out to be strongly hydrogen-deficient. The finding was reported in a research paper ...
