First-ever image of cool gas disk surrounding Milky Way's black hole
..., or shifted, to the “redder” portion of the spectrum; the blue color represents gas moving toward Earth, so the radio waves are slightly scrunched, or shifted, to the “bluer” portion of the spectrum. Image: ALMA (ESO/NAOJ/NRAO), E.M. Murchikova...

Neutron star natal kicks could be the catalyst for binary formation and new gravitational wave sources
... results in a supernova explosion. Some neutron stars turn into rapidly rotating stars that emit regular pulses of radio waves (and other types of electromagnetic radiation) at rates of up to one thousand pulses per second. These are known as pulsars...
