Using NASA's Fermi Gamma-ray Space Telescope, Chinese astronomers have detected significant GeV gamma-ray emission from a supernova remnant (SNR) known as G272.2-3.2. The finding is detailed in a paper published March 29 ...
This image taken by the NASA/ESA Hubble Space Telescope revisits the Veil Nebula, which was featured in a previous Hubble image release. In this image, new processing techniques have been applied, bringing out fine details ...

Using the Australia Telescope Compact Array (ATCA) and the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have conducted a study of two magnetars known as PSR J1622−4950 and 1E 1547.0−5408. Results of ...
Astronomers may have found our galaxy's first example of an unusual kind of stellar explosion. This discovery, made with NASA's Chandra X-ray Observatory, adds to the understanding of how some stars shatter and seed the universe ...
