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 ...

Using the Very Large Array (VLA), an international team of astronomers have observed a nearby galaxy merger known as CIZA J0107.7+5408. Results of the observational campaign, presented December 20 on the preprint server arXiv, ...

Using the James Webb Space Telescope (JWST), an international team of astronomers has detected a new grand-design spiral galaxy as part of the PANORAMIC survey. The newfound galaxy, named Zhúlóng, is extremely massive and ...

Indian astronomers have performed a multiwavelength study of a gamma-ray emitting compact symmetric object known as DA 362. Results of the study, presented in a research paper published December 17 on the pre-print server ...

An international team of astronomers has reported the discovery of a new pulsar, which received the designation PSR J1631–4722. The newfound pulsar, which is young and energetic, turns out to be associated with a supernova ...

An international team of astronomers has reported the discovery of two exoplanets orbiting a nearby star known as HD 101581. The newfound alien worlds are slightly smaller than Earth and orbit its host very closely. The discovery ...

Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China, astronomers have discovered a new pulsar with a spin period of about two seconds. The newly detected pulsar, designated PSR J1922+37, was found ...

An international team of astronomers has analyzed multi-color photometric and spectroscopic observations of the star Gaia20bdk. As a result, they found that Gaia20bdk is a FUor-type young stellar object. The finding is presented ...
