Russian astronomers have conducted photometric observations of a unique extremely metal-poor luminous blue variable star known as DDO68-V1. Results of the observational campaign, published Jan. 28 on the arXiv pre-print server, ...

Astronomers from Turkey and Japan have performed optical observations of a recently discovered nearby supernova remnant known as G206.7+5.9. Results of their observations, published Jan. 28 on the arXiv pre-print server, ...

Using the Keck Planet Imager and Characterizer (KPIC), astronomers have performed high-resolution spectroscopic observations of a brown dwarf known as HD 206893 B. Results of the observational campaign, presented Jan. 23 ...

Using the Gran Telescopio Canarias (GTC) and the Apache Point Observatory (APO), an international team of astronomers has detected 19 pulsation modes in an ultra-massive white dwarf known as WD J0135+5722. The discovery, ...

Using the Hubble Space Telescope (HST), astronomers from the University of California Santa Cruz (UCSC) and elsewhere have observed an ultra-diffuse galaxy known as FCC 224. Results of the observational campaign, published ...

Using the Very Large Telescope (VLT), Chilean astronomers have observed a cataclysmic variable known as V1425 Aql. As a result, they have found that this system hosts an arc-shaped nova shell. The finding is presented in ...

Chinese astronomers have investigated quasar candidates from the DESI Legacy Surveys (DESI-LS) photometry catalog. As a result, they detected 19 strongly-lensed, dual and projected quasars. The finding was reported in a paper ...

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 ...
