In this undated image provided by Adam Summers, a University of Washington professor in the department of Biology and the School of Aquatic and Fisheries Sciences, a scan of the Thoracocarax Stellatus species of fish is shown, with color added by computer to enhance the rendering of the structure of the bones. Summers is using a micro computed tomography, also known as "CT," scanner at a lab on Washington's San Juan Island as part of an ambitious project to scan and digitize more than 25,000 species in the world. The idea is to have one clearinghouse of CT scan data freely available to researchers anywhere to analyze the morphology, or structure, of particular species.

NASA's Voyager 1 took this photo of Jupiter's Great Red Spot in 1979. Scientists have long wondered why Jupiter’s upper atmosphere has temperatures similar to those of Earth, even though the biggest planet in the solar system is five times farther away from the sun. The answer may be The Great Red Spot, an enormous storm big enough to swallow three Earths that has been raging on Jupiter for at least three centuries, a study showed on Wednesday. Using an infrared telescope at Hawaii’s Mauna Kea Observatory, scientists discovered that the upper atmosphere above the Great Red Spot – the largest storm in the solar system – is hundreds of degrees hotter than anywhere else on the planet. The storm spans 22,000 kilometers by 12,000 kilometers (13,670 miles by 7,456 miles) and is located in Jupiter’s lower atmosphere. The top of its clouds reach altitudes of about 50 km (31 miles). By a process of elimination, the newly found hot spot must be heated from below, the study concluded. The finding provides a strong link between Jupiter’s upper and lower atmosphere, though the exact process by which heat is transferred remains unknown. The most likely energy source is acoustic waves that provide heat from below, the study said. Scientists also are unsure why the storm is brick red, nor why it has changed color over time. In a 1900 report in the Seattle Post-Intelligencer, scientists described the oval storm as salmon pink. Recent images from the Hubble Space Telescope show it has become orange tinged and more circular. (Photo by Reuters/NASA)

This handout file artist impression released on November 12, 2014 by the ESA/ATG medialab shows the European probe Philae separating from its mother ship Rosetta and descending to the surface of comet 67P/Churyumov-Gerasimenko. Ground controllers bid a final farewell on July 27, 2016 to robot lab Philae, cutting communications after a year-long silence with the tiny probe hurtling through space on the surface of a comet. The decision to cut the link was taken to save energy on mothership Rosetta, orbiting around comet 67P/Churyumov-Gerasimenko, for the final weeks of its own historic mission.
