ESA’s new Herschel Space Observatory and NASA’s Spitzer Space Telescope combine to show the Milky Way at its coldest and hottest. From NASA/JPL/Caltech’s Hidden Universe series.
Last year, Saturn moved into a rare position that allowed the Hubble Space Telescope to image its northern and southern aurorae at the same time. From ESA’s HubbleCast, with the famous Dr. J.
Earth’s landmasses were not always what they are today. Continents formed as Earth’s crustal plates shifted and collided over long periods of time. This video shows how today’s continents are thought to have evolved over the last 600 million years, and where they’ll end up in the next 100 million years.

NASA scientists used radar data to reconstruct surface features on Titan, Saturn’s largest moon. They found that this frigid methane world has some striking similarities to places on Earth. From NASA’s Jet Propulsion Laboratory.
Fascinating account of how technicians remove a giant telescope mirror at the Very Large Telescope Array in Chile and then clean and refinish it.
This is a flight down into a data visualization of the undersea mountains and trenches of the Pacific Ocean, ending up in the deepest part of the ocean, the Marianas Trench. The “Challenger Deep” is measured at 35,813 feet below the surface, or 10,915 meters. Courtesy of NOAA’s Marine Geology and Geophysics Division.
The last decade has been measured as the hottest on record all around the globe. This overall result is derived from a patchwork of readings with widely varying effects on local climates. Scientists agree that the change is being spurred by rising levels of carbon dioxide in the atmosphere. This clip was produced by NASA’s Goddard Space Flight Center.
Saturn Cassini mission team members from NASA’s Jet Propulsion Lab recount their observations of lightning bolts flashing in the outer regions of Saturn’s atmosphere.
The famous Dr. J. stages an awards ceremony for the Hubble Space Telescope. He summarizes Hubble’s major achievements and its central role in a revolution in our understanding of the universe.
