Jon Lomberg (born 1948) is an American space artist and science journalist. He was Carl Sagan's principal artistic collaborator for more than twenty years on many projects from 1972 through 1996.  In 1998, the International Astronomical Union officially named an asteroid ( 6446 Lomberg) in recognition of his achievements in science communication.  
Jon Lomberg grew up in Philadelphia, Pennsylvania.  During a visit to Toronto, Ontario, after college, he was invited by science fiction author Judith Merril to display his artwork at a conference she organised for the Ontario Institute for Studies in Education.  Lomberg moved to Toronto later that year and, after assisting Merril in a radio documentary for the CBC Radio One program Ideas, went on to create many documentaries on topics such as NASA's Viking program and Halley's Comet for the program.   
In 1972, Lomberg showed some of his paintings to astronomer Carl Sagan,  who then asked him to illustrate his book The Cosmic Connection (1973). This was the beginning of their quarter century of collaboration on many projects, including the Cosmos series (for which Lomberg created the talent pool  and as chief artist   won a Primetime Emmy Award); the Cosmos book; Broca's Brain;   NASA's interstellar Voyager Golden Record;    the original cover art for Sagan's 1985 novel Contact;  and the opening sequence from Earth through the Solar System and its galaxy and beyond for the 1997 Contact film.   At Sagan's request,  Lomberg designed the original sailing ship logo for the Planetary Society in 1981. 
The Smithsonian Institution commissioned Lomberg in the early 1990s to paint "A Portrait of the Milky Way", a scientifically accurate artistic representation of the Milky Way galaxy as seen by a hypothetical observer from a vantage point 10 degrees above the galactic plane and 60,000 light years from the galactic center.   The 6 ft (1.8 m) by 8 ft (2.4 m) painting, which was described in a peer reviewed academic paper in 1994 as "the best representation of our galaxy to date" and "a first map like those of explorers long ago",  was displayed in the National Air and Space Museum from 1992 through 2002 and remains part of its permanent collection of aviation and space art.  Lomberg also designed the Galaxy Garden, a three-dimensional walk-through Milky Way scale model which is part of the Paleaku Peace Gardens Sanctuary in Kailua-Kona, Hawaii.  
Lomberg co-designed the MarsDial   aboard the Mars Exploration Rovers Spirit and Opportunity, and was the project director and editor-in-chief  for the Visions of Mars CD-ROM and mini- DVD aboard the spacecraft Phoenix, which landed on Mars in May 2008. He was also on the Waste Isolation Pilot Plant planning teams with Frank Drake, Ben Finney, Ward Goodenough, Louis Narens, Frederick Newmeyer, Woodruff Sullivan and others.   
Jon Lomberg is a founding member of the International Association of Astronomical Artists,  a member of the Planetary Society advisory council,  and designs exhibits and gives presentations for the Mauna Kea Astronomy Education Center in Hilo, Hawaii for the Mauna Kea Observatory and Gemini North.    He lives in Hawaii with his wife and two children.

Artist John Lomberg and astrophysicist Jeff Goldstein spent a year plotting the positions of nebulae and star clusters we can see in the night sky. They also drew upon the latest research about the galaxy's structure. They used radio observations to plot the broad sweep of its spiral arms, for example. Lomberg then set up a six-foot-by-eight-foot canvas in a hut on the island of Hawaii. He painted with airbrush and acrylics. At night he covered the forming galaxy to keep the geckos away…

[Image caption.] Installation of the map in 1992. Note the cutout in the light baffle wall on the right. It held a backlit Milky Way portrait by Emmy Award winning space artist Jon Lomberg. The portrait faced outward and served as a Stellarium introduction. Research by the museum's astrophysics department gave the renowned artist the basis for the most accurate portrait possible. It also gave the first evidence that our galaxy is a barred spiral.
