By analyzing data from ESA's XMM-Newton spacecraft and NASA's TESS telescope, German astronomers have inspected a highly variable polar known as V496 UMa. Results of the study, published May 20 on arXiv.org, deliver more ...
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), astronomers have observed a young planetary nebula known as IC 4997. Results of the observational campaign, presented in a paper published May 12 on ...
New chemistry "forensics" indicate that the stone named Hypatia from the Egyptian desert could be the first tangible evidence found on Earth of a supernova type Ia explosion. These rare supernovas are some of the most energetic ...
