Using NASA's Chandra X-ray observatory, astronomers have carried out an X-ray proper motion study of a supernova remnant known as SNR 0509-67.5. Results of the research, published October 5 on arXiv.org, yield essential information ...
Using NASA's Chandra X-ray observatory, astronomers from the Harvard-Smithsonian Center for Astrophysics (CfA) and elsewhere have investigated an active galaxy known as Markarian 78. They report that the source exhibits termination ...
Light on, light off—this is how one could describe the behavior of the nova, which goes by the name RS Ophiuchi (RS Oph). Every 15 years or so, a dramatic explosion occurs in the constellation of the Serpent Bearer. Birthplaces ...

An international team of astronomers has carried out a comprehensive radio and X-ray monitoring of a black hole X-ray binary known as MAXI J1348–630. The observational campaign provided important insights into the evolution ...
The interstellar medium and combustion systems contain polycyclic aromatic hydrocarbons (PAHs) as fundamental molecular building blocks that form fullerenes and carbonaceous nanostructures. However, researchers have yet to ...
