Astronomers have found a pulsating, dead star beaming with the energy of about 10 million greater than the Sun. A pulsar is a dense stellar remnant left over from a supernova explosion, and this one is the brightest pulsar ever recorded. The discovery was made using the Nuclear Spectroscopic Telescope Array, or NuSTAR. The pulsar is shown in pink at the center of the Messier 82 galaxy in this multi-wavelength image. NASA’s NuSTAR mission discovered the “pulse” of the pulsar using its high-energy X-ray vision.
