Using NASA's Chandra X-ray Observatory, an international team of astronomers has conducted deep imaging observations of a high-redshift radio galaxy known as 4C 63.20. The observational campaign has revealed an extended X-ray ...
An international team of astronomers including Stella Offner of the University of Texas at Austin has proposed a new method for the formation of aluminum-26 in star systems that are forming planets. Because its radioactive ...
