Mark C. Petersen has been creating space music using the nom-de-plume Geodesium for many years. He got his start at the University of Colorado when he was a music student and gained access to the School of Music's Moog Series III instrument. He began with transcriptions of Bach and Pachelbel, learning his craft and adding to his keyboard studio collection as he went. His planetarium space music career began at the University's Fiske Planetarium, and has grown over the years to include music and soundtracks for more than 60 planetarium shows, dozens of podcasts for 365 Days of Astronomy and the Astronomical Society of the Pacific, video presentations for MIT's Haystack Observatory, plus many other multimedia presentations. Outside of the planetarium and science outreach world, Mark's music has been used for selected commercial soundtracks.

At the urging of many pleased planetarium patrons, Mark began releasing his music on commercial albums, beginning with the eponymous album GEODESIUM. Today, he has more than a dozen albums available. The music on most of the albums encompasses a style that has often been described as atmospheric and immersive, taking listeners on aural journeys throughout the cosmos. So far, the only two exceptions are his 2010 Music from SpacePark360 and the follow-up album Music From Infinity, which are wild rides through musical genres as diverse as acid, house, techno, trance, electronica, rock, and yes, some space music.

When not composing Geodesium music for soundtracks, Mark spends much of his time in video production and distribution of fulldome shows to theaters around the world. Mark is also an accomplished tuba player, and throughout his career has performed with community bands and brass quintets.

The pictures are so dark because I think they were trying for some artsy "space-like" lighting.
