By analyzing the data from Leahy's atlas of double radio-sources and NASA/IPAC Extragalactic Database (NED), Serbian astronomers have explored an X-shaped radio galaxy designated 3C 315. Results of the new study, published ...

An international team of astronomers reports the detection of two new brown dwarfs orbiting distant stars using NASA's Transiting Exoplanet Survey Satellite (TESS). The newfound objects are about 30 times more massive than ...

Italian astronomers report the detection of a new X-ray binary (XRB), which has received the designation 4XMM J181330.1-17511 (J1813 for short). The newfound object represents the rare subclass of XRBs known as supergiant ...

Using the Australia Telescope Compact Array (ATCA), astronomers have performed high-resolution observations of a nearby pulsar wind nebula in the supernova remnant G11.2−0.3. Results of the observational campaign, published ...

Chinese astronomers investigated the spectral and temporal properties of a black hole X-ray binary system known as SLX 1746–331, during its recent outburst. Results of the study, published in The Astrophysical Journal Letters, ...

Using the James Webb Space Telescope (JWST), astronomers have observed enigmatic rings in the planetary nebula NGC 1514, visible in the mid-infrared band. Results of the new observations, published Feb. 28 on the arXiv pre-print ...

Astronomers from Poland and Germany have performed photometric and spectroscopic observations of a blue variable object designated OGLE-GD-WD-0001. As a result, they found that the investigated object is an extremely hot ...

Using the ROentgen SATellite (ROSAT), astronomers have discovered a new cataclysmic variable system of the polar subtype. The new polar, which received the designation ZTF J0112+5827, has an orbital period of approximately ...

By analyzing multiwavelength data from various space telescopes and astronomical surveys, Chinese astronomers have explored the long-term variability of a blazar known as PKS 0727-11. Results of the new study, published in ...

Astronomers have performed a multiwavelength study of nine open cluster candidates. As a result, they found that all of them are genuine open clusters and characterized by their fundamental properties. The finding was reported ...

Using the James Webb Space Telescope (JWST), an international team of astronomers has explored the atmosphere of a nearby brown dwarf binary designated WISE J045853.90+643451.9. As a result, they detected hydrogen cyanide ...

Chinese astronomers have analyzed the data from NASA's Swift observatory, which extensively observed an outburst of the cataclysmic variable system known as GK Persei. Results of the study, published February 20 on the arXiv ...
