New observations of a massive neutron star provide clues about these extreme objects’ interiors.
Most galaxies are either star-forming disks or red-and-dead spheroids — but Astrobites reports on new findings that complicate this simple divide.
How can we spot supermassive black holes lurking outside of their galaxies’ centers? These wanderers may not remain lost!
