NuSTAR finds new clues to ‘chameleon supernova’
“We’re made of star stuff,” astronomer Carl Sagan famously said. Nuclear reactions that happened in ancient stars generated much of the material that makes up our bodies, our planet and our solar system. When stars explode in violent deaths called supernovae, those newly formed elements escape and spread out in the universe.

Pulsar with black hole could hold the ‘holy grail’ of gravity
The intermittent light emitted by a pulsar allows scientists to verify Einstein’s theory of relativity, especially when paired up with another neutron star that interferes with its gravity. According to researchers from Spain and India, this theory could be analysed much more effectively if a pulsar with a black hole were found.
