An international team of astronomers has performed multi-epoch optical and near-infrared observations of a slow nova known as V2891 Cygni. Results of the study, published December 26 on the arXiv pre-print repository, deliver ...
It began, as all modern astronomical alerts seem to, with one tweet, then two. Early on the morning of Friday, March 19, we started seeing word that a nova was spotted in the constellation of Cassiopeia the Queen, near its ...

Using the Zwicky Transient Facility (ZTF) and the Caucasus Mountain Observatory (CMO), Russian astronomers have investigated a peculiar source designated ZTF18abdlzhd. The observations revealed that this object is an SU UMa-type ...
A nova, or stella nova, the Latin word for "new star," is an explosion on the surface of a star that can produce enough energy to increase the star's brightness by millions of times. Sometimes a nova, which occur in stars ...

Astronomers have conducted observations of a symbiotic star in the Large Magellanic Cloud (LMC), known as LMC S154, which provide new insights about the nature of this object. Results of these observations, presented in a ...
A San Diego State University astrophysicist has helped discover evidence of a gigantic remnant surrounding an exploding star—a shell of material so huge, it must have been erupting on a regular basis for millions of years.
