About a hundred and forty years ago, the light from a supernova explosion in our galaxy reached the Earth, but no one saw it. The discovery of this supernova remnant helps astronomers better understand how often these stellar time-bombs go off in our galaxy.
In 3C321, a jet from a black hole in one of the galaxies is pummeling its neighbor galaxy, the first time this type of galactic violence has ever been seen. The jet could bring big trouble for any planets in its path, but could also trigger a burst of star formation in its wake.
Like the Milky Way, Sombrero is a spiral galaxy. However, we see Sombrero edge-on from our vantage point from Earth, rather than the face-down perspective that is more familiar.
The supernova explosion that created this object was witnessed on Earth about 400 ago years by many skywatchers, including the astronomer Johannes Kepler. This object, which now bears Kepler's name, is the remains of a massive star's demise.
