Latest Supernova remnant Stories
NASA’s Swift space observatory detected the previously undiscovered remains of a supernova during an extensive X-ray survey of the Milky Way.
As it floats around the planet Saturn, the Cassini spacecraft recently got a front row seat to what NASA astronomers are calling an “unusual strong blast of solar wind.” Shortly after this “wind” blew by, Cassini began detecting particles which had been accelerated to ultra-high energies.
For the first time, scientists working with the Cassini spacecraft have detected subatomic particles accelerated to ultra-high energies in a blast of solar wind around Saturn, hinting at the possibility that the ringed planet may have experienced the aftermath of a supernova.
NASA has released a pair of new images captured by NuSTAR – one depicting a pair of black holes lurking inside a spiral galaxy, and the other featuring a look at the supernova remnant Cassiopeia A.
Researchers may have discovered the fastest moving pulsar ever seen using NASA's Chandra X-ray Observatory and ESA's XMM-Newton.
Astronomers studying the Vela pulsar wind nebula with ESA's INTEGRAL observatory have successfully resolved its morphology in the hard X-ray band, for the first time.
In early November 1572, observers on Earth witnessed the appearance of a "new star" in the constellation Cassiopeia, an event now recognized as the brightest naked-eye supernova in more than 400 years.
The constellation Cygnus, now visible in the western sky as twilight deepens after sunset, hosts one of our galaxy's richest-known stellar construction zones.
Every three hours, NASA's Fermi Gamma-ray Space Telescope scans the entire sky and deepens its portrait of the high-energy universe.
