Image of the Day: Galaxy M82 -Home of a Mystery Signal Unlike Anything in the Known Universe
M82, a starburst galaxy was previously believed to be an irregular galaxy. However, in 2005, two symmetric spiral arms were discovered in the near-infrared (NIR) images of M82. The arms were detected by subtracting an axisymmetric exponential disk from the NIR images.
In April 2010, radio astronomers working at the Jodrell Bank Observatory of the University of Manchester reported an unknown object in M82. The object has started sending out radio waves, and the emission does not look like anything seen anywhere in the universe before. There have been several theories about the nature of this unknown object, but currently no theory entirely fits the observed data. It has been suggested that the object could be a "micro quasar", having very high luminosity, and being fairly stable. However, microquasars also produce large quantities of X-rays, whereas no X-rays have been seen from the mystery object.The object is located at several arcseconds from the center of M82.

Why does Daily Galaxy continue to post old stories as if they're new? It's misleading and it's bad journalism. This story originally came out in April of 2010.

Why do people whine about things other people do as if they have done better?

It is simply explaining the Image of the Day... I does not mention anywhere "This just in!" or "Breaking News!".
