Moški Rokometni Klub Krka (English: Men's Handball Club Krka), commonly referred to as MRK Krka or simply Krka, is a team handball club from Novo Mesto, Slovenia. Currently, it competes in the Slovenian First League of Handball.
MRK (Markos Kay) is a visual artist, creative director, illustrator and lecturer based in London, best known for his artificial life video art experiment "aDiatomea" (2007), a permanent exhibit at the Phyletic Museum in Jena, Germany. His 3D generative short "The Flow" (2011) has been shown internationally as part of "Resonance" a collaboration of over 30 independent visual artists and sound designers. MRK's films have been exhibited worldwide, including OFFF Barcelona, Pause Fest Melbourne, Onedotzero London, Stroke Artfair Berlin and Viedram Rome.
MRK graduated with a Master of Arts in Communication Design from Central St. Martins in 2007 and is currently working as a creative director, motion designer and lecturer.
In 2008, MRK released “aDiatomea,” an experimental piece that simulates diatoms consisting of realistic 3d generated diatoms. Each variant of these mathematical creatures is classified in actual taxonomies, giving Victorian diatom art a 21st-century redux.Granular sound is 'injected' into the diatoms affecting their form and movement, creating a dynamic system. In 2012, "aDiatomea" was part of the official selection at Imagine Science Films in New York.

Markarian 421 (Mrk 421, Mkn 421) is a blazar located in the constellation Ursa Major. The object is an active galaxy and a BL Lacertae object, and is a strong source of gamma rays. It is about 397 million light-years (redshift: z=0.0308 eq. 122Mpc) to 434 million light-years (133Mpc) from the Earth. It is one of the closest blazars to Earth, making it one of the brightest quasars in the night sky. It is suspected to have a supermassive black hole (SMBH) at its center due to its active nature, and has a companion galaxy (Markarian 421-5) that is fueling the gas jets observed pointing away from the galaxy.
It was first determined to be a very high energy gamma ray emitter in 1992 by M. Punch at the Whipple Observatory, and an extremely rapid outburst in very high energy gamma rays (15-minute rise-time) was measured in 1996 by J. Gaidos at Whipple Observatory
Markarian 421 also had an outburst in 2001 and is monitored by the Whole Earth Blazar Telescope project.
Due to its brightness (around 13.3 magnitude, max. 11.6mag. and min. 16mag.) the object can also be viewed by amateurs in smaller telescopes.
