M82 Cigar Galaxy in Ursa Major

Messi­er 82 (also known as NGC 3034, Cigar Galaxy or M82) is a star­burst galaxy approx­im­ately 12 mil­lion light-years away in the con­stel­la­tion Ursa Major. As mem­ber of the M81 Group, it is about five times more lumin­ous than the Milky Way and has a cen­ter one hun­dred times more lumin­ous. The star­burst activ­ity is thought to have been triggered by inter­ac­tion with neigh­bor­ing galaxy M81. As the closest star­burst galaxy to Earth, M82 is the pro­to­typ­ic­al example of this galaxy type.

About Me

Hello, my name is Martin Rusterholz. I’m a Swiss amateur astrophotographer living near Zurich, the biggest town in Switzerland. My interest in astronomy started when I was 16. At that time, I built my first Newtonian telescope and mount. I studied physics at the Swiss Federal Institute of Technology (ETH) which was the only study including at least some aspects of astronomy and astrophysics. “Looking at the nights sky is an experience touching everybody deeply inside, something common to all human beings independent to the language spoken by the individuals”. Deep-sky astrophotography is my passion.
