NASA's Mars Curiosity rover took this photo of the rock named Duluth on May 15. The block is about 3 feet long. This isn’t the first time “Duluth” has appeared on Mars. The name was first used on a ChemCam laser target several years back. Normally names are used just once, but the mission team made an exception. NASA / JPL-Caltech

After removing the observatory dome shutter, sheet metal workers, including supervisor Kevin Holappa (left), lower it to the ground at the home of former UMD planetarium director Glenn Langhorst in Moose Lake earlier this week. The crew worked to disassemble the dome one "slice" at a time, crated it and then hauled it back to UMD, where it will one day be reassembled and house a new telescope. Bob King /

The Milky Way and three bright stars of the Summer Triangle stand out in dark, light-pollution-free skies well north of Duluth. Within and near the city, lights can make it difficult to see the stars well. Bob King /
