At 240 million light-years away, galaxy NGC 1277 hasn't formed new stars in over 10 billion years. Could it contain the first stars' ashes?Continue reading on Starts With A Bang! »
Astronomers have sharply revised down the mass of nearby super Earth GJ 3378b, dramatically improving its prospects as a potentially habitable world for alien life.
A strange "chirping" signal from a distant supernova has revealed the birth of a magnetar, confirming that these incredibly magnetic neutron stars can power the universe's brightest stellar explosions. The discovery also marks the first time Einstein ...
