Fermi Spacecraft : More Gamma Ray Pulsars (NASA)
|
|
|
| Ordinary pulsars are detected
by means of their narrow beam radio signals or x-ray emissions. Some
pulsars have remained hidden because they are oriented such that the
beams miss Earth. They do, however, emit more broadly in gamma rays.
Fermi finds these. |

have also increased. It is now thought to be more massive than the
well known galaxy in Andromeda though the latter has more stars.
