Using ESA's XMM-Newton space telescope, astronomers have spotted bright X-ray outbursts emitted by a Be/X-ray binary known as A0538−66. The discovery marks the ending of an over three-decade-long period of quiescence of ...
Using a set of various ground-based telescopes, European astronomers have conducted photometric and spectroscopic observations of a symbiotic binary known as AG Draconis. Results of this observational campaign, presented ...
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 ...
On March 11, an instrument aboard the International Space Station detected an enormous explosion of X-ray light that grew to be six times as bright as the Crab Nebula, nearly 10,000 light years away from Earth. Scientists ...

Brazilian astronomers have performed photometric observations of the dwarf nova V2051 Oph during its quiescent period, which revealed important insights into the nature of this object. The results were presented in a paper ...
European astronomers have spotted an unusual outburst activity of a binary star system known as AG Draconis. New observations reveal that the recent changes of brightness of this star are slightly different than the changes ...
Researchers from Niels Bohr Institute, University of Copenhagen, Denmark, studied satellite photographs of Lake Catalina, an ice-dammed lake in East Greenland – and were truly amazed: Unnoticed by science as well as people ...
