Using NASA's Swift telescope and the Neutron star Interior Composition Explorer (NICER) instrument onboard the International Space Station, Indian astronomers have inspected timing and spectral properties of an X-ray transient ...
Roughly a half-century ago, astronomers realized that the powerful radio source coming from the center of our galaxy (Sagitarrius A*) was a "monster" black hole. Since then, they have found that supermassive black holes (SMBHs) ...

By analyzing a large set of photometric data, astronomers have investigated KT Eridani—a nova detected in 2009. The study, published October 19 on arXiv.org, found that KT Eridani is a recurrent nova with a recurrence time-scale ...
An international team of astronomers reports the detection of a new planetary system by observing a nearby star known as HD 18599 (or TOI-179). It appears that this star is orbited by a Neptune-mass exoplanet and a massive ...
Researchers at the Institut für Astronomie und Astrophysik in Germany have found evidence that suggests the extremely tiny neutron star, HESS J1731-347, may in fact be a "strange" star. In their paper published in the journal ...
Using the Caucasus Mountain Observatory, Russian astronomers have investigated a nearby lenticular galaxy known as NGC 4324. They detected young star-forming complexes in the inner ring of this galaxy. The findings, presented ...
Using various spacecraft and ground-based telescopes, astronomers have conducted multiwavelength observations of a Type IIn supernova known as SN 2017hcc. Results of the observational campaign, published October 6 on arXiv.org, ...
