Galaxy Zoo: Hubble 100 Year Starship Study Signs of Hidden Ocean Underneath Titan's Crust Astronomers' mental image of Titan, the solar system's second-largest moon, used to be that of a vast swimming pool. But maybe they should have imagined a water bed instead. Last year, researchers reported that radar mapping of Titan by the Cassini spacecraft had found a peculiar shift in landmarks on the moon's surface of up to 19 miles (30 kilometers) between October 2004 and May 2007. Now investigators say the best explanation is a moon-wide underground ocean that disconnects Titan's icy crust from its rocky interior. "We think the structure is about 100 kilometers of ice sitting atop a global layer of water … maybe hundreds of kilometers thick," says Cassini scientist Ralph Lorenz of Johns Hopkins University Applied Physics Laboratory in Laurel, Md. If confirmed, Titan would be the fourth moon in the solar system thought to contain such an internal water ocean, joining Jupiter's satellites Ganymede, Callisto and Europa. There may also be other explanations for the observed shifting.
ТЕСИС - космическая обсерватория News Blog - Mike Lynch's "Exploding" Telescope Here's a cautionary story about someone who was careful with his observing gear — and still got burned. Some of you probably know (or know of) Mike Lynch, an avid amateur astronomer who hosts frequent star parties in the Minneapolis-St. Paul area. He's the author of several skywatching books, writes a column for the Twin Cities' Pioneer Press, and hosts an astronomy website. You might not know that he's been a meteorologist for radio station WCCO for nearly 30 years. A week ago Lynch headed off to the radio station after observing the night before with his 14½-inch Starmaster Dobsonian. Well, later that morning, Lynch got a frantic call from his wife. It didn't take him long to figure out what had happened. "The wind blew the cover off," he explains. Luckily, his wife caught sight of the fiercest fire she's ever seen, and her call to 911 kept the damage confined to the deck and, sadly, to the telescope.
Apollo 11 Flight Journal - Index Page National Aeronautics and Space AdministrationNASA History Division David Woods, Ken MacTaggart and Frank O'Brien Welcome to this 29 March 2011 release of the Apollo 11 Flight Journal, part of the Apollo Flight Journal series.

Plútó és Charon film a nitrogénjéggel borított fagyott égitestek felszínéről Mínusz 220 Celsius-fokos fagyott nitrogénjég tömbök borítják a távoli törpebolygó, a Plútó felszínét. Egén apró pont csak a messzi Nap, amely alig okoz halvány derengést a felszínen. Ezerszer sötétebb van délidőben a Plútó felszínén, mint a Földön. Így nézhet ki a Plútó felszínéről nézve az égbolt A fagyos égitest felszínét főleg nitrogénjég, valamint fagyott metán és néhány egyéb jég borítja. A videón az égitest fagyott felszíne látható, egén jobbra a távoli Nap, balra pedig legnagyobb holdja, a Charon figyelhető meg. Film a New Horizons-űrszonda küldetéséről
W. M. Keck Observatory Pillow Astronaut Wow! Signal - 30th Anniversary Report Introduction The "Wow!" source radio emission entered the receiver of the Big Ear radio telescope at about 11:16 p.m. In this Introduction I will first describe briefly the "Big Ear" radio telescope. The "Big Ear" Radio Telescope Here is an aerial photo of the "Big Ear" radio telescope of the Ohio State University Radio Observatory looking approximately east by northeast. The aerial photo to the right shows a view looking north by northwest. The photo to the left is a view looking almost due west. Each of the above photos was taken in 1995, about 18 years after the occurrence of the "Wow!" Below is a diagram of the design of the Big Ear radio telescope showing the path that a typical incoming radio wave takes from the source to the flat reflector, then to the paraboloidal reflector, and then into the feed horns and electronics. More information can be found about the structures of the "Big Ear", Dr. The Computer Printout The Page Layout Below are two important images. For the strongest Wow!
