Supernova Shock Wave Blows-Away Huge Clumps of Cosmic Clutter | Video

A supernova remnant called G352.7-0.1 has swept away about 45 times the Sun's mass worth of material during its expansion. This is an unusual occurrence, leading researchers to believe that remnant interacted with a massive amount of dense material.  A Chandra X-ray telescope study of the remnant (that is about 24,000 lights years from Earth) was used to make the find.
