Using the Lijiang Observatory, astronomers from the Chinese Academy of Sciences (CAS) have inspected a gamma-ray blazar known as S5 0716+714. The observations provided important insights into the spectral behavior of this ...
The detection more than a decade ago by the Fermi Gamma Ray Space Telescope of an excess of high-energy radiation in the center of the Milky Way convinced some physicists that they were seeing evidence of the annihilation ...

When a massive star reaches the end of its life, it can explode in a process known as a supernova. The massive star—much more massive than our sun—runs out of fuel in its core. Gravity forces the core to collapse on itself, ...
