This dramatic Hubble image shows the Nebula M1-67 around star WR124 as 100 billion-mile wide glowing gas blob 15,000 light-years away, located in the constellation Sagittarius. Each blob is about 30 times the mass of the Earth. Vast arcs of glowing gas surrond the star, which are resolved into filamentary, chaotic substructures. WR124 is surrounded by hot clumps of gas being ejected into space at speeds of over 100,000 miles per hour with no overall global shell structure. The massive, hot central star is a Wolf-Rayet star -an extremely rare and short-lived class of super-hot star that is going through a violent, transitional phase characterized by the fierce ejection of mass.
