A 3D View of the Remnant of Nova Persei 1901

GK Per (Nova Persei 1901) nova remnant is the result of a remarkable nearby nova exploded in 1901 which reached the
brightness of the star Vega at its maximum. It was the first object around which, superluminal light echoes where observed.
The actual ejecta of the outburst became visible 15 years later in 1916. Ever since, the ejecta has been monitored in
several wavelengths in narrow- and broad-band filters. This study shows that the nova ejecta is a thick knotty shell in
which knots expand with a significant range of velocities. A movie shows the evolution of the remnant from 1953 to 2011 using data mainly from the
INT/WFC and INT/IDS.
