Massive star explosion captured in photo
A massive star explosion was captured in a photo by NASA.
The photo shows the remnant of a supernova, Cassiopeia A, which is 11,000 light years away from Earth, NASA said.
The photo was captured by NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR), an X-ray telescope.
A supernova is caused when a large star collapses on itself.
