Using ESA's XMM-Newton and NASA's NuSTAR space telescopes, a team of astronomers from Germany has detected a new ultra-luminous pulsar in the galaxy NGC 300. The finding of this pulsar, which received designation NGC 300 ...
Collisions between galaxies, and even less dramatic gravitational encounters between them, are recognized as triggering star formation. Observations of luminous galaxies, powered by starbursts, are consistent with this conclusion. ...
