SIMBAD Astronomical Database SIMBAD on the Web is the WWW interface to the SIMBAD database. It offers the following functionalities: Query by identifiers and around identifiers Query by coordinates, specifying the radius and the equinox Query by bibcode and partial bibcode Sampling with a set of physical criteria Query by lists of objects, coordinates or bibcodes Display charts for list of objects resulting from coordinates query Moreover, the interface provides links with many other data services : Links to the other CDS services: Tables in VizieR, giving access to the whole catalogued data, links to Aladin images, surveys and observatory logs.

Angler Fish Challenges Frog's 'Smallest' Title Sitting end to end, two recently discovered frogs couldn't straddle a dime. Still, one scientist contends these diminutive creatures aren't record setting. Instead, he champions a tiny male fish for the title of smallest vertebrate, or animal with a backbone. The contenders: A tropical frog Paedophryne amanuensis, which averages just 0.30 inches (7.7 millimeters) long, was given the "smallest vertebrate" title this week when news broke of its discovery Wednesday (Jan. 12). However, a male angler fish (Photocorynus spiniceps), which lives as a parasite on the angler-fish female and can measure as much as 0.03 in. (0.8 mm) less than the smallest of these tiny frogs, deserves the title, according to Ted Pietsch, curator of fishes at the Burke Museum at the University of Washington. The smallest of the newly identified frog species measures 0.28 in. (7.0 mm) from the tip of its snout to its anus, or vent.

If you're tired of standing by while Curiosity rolls around up there, it's time to head out on the open exosphere and explore the universe for yourself — digitally, of course. SEE ALSO: 10 Must-Follow Tumblrs for Science Lovers A handful of excellent space simulators use real astronomical data to re-create the known universe in three dimensions. Fly through the galaxy at ludicrous speeds, map out humanity's best hope for extrasolar colonization, or mess with physics to create your own cosmic recipes. Some of these simulations stick to our own solar system, while others push the boundaries of our cosmological projections, procedurally generating star systems far beyond our galactic neighborhood.

If the Moon Were Only 1 Pixel - A tediously accurate map of the solar system Mercury Venus Earth You Are Here 10 Strange Things About The Universe Space The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Theoretically, the lowest temperature that can be achieved is absolute zero, exactly ?273.15°C, where the motion of all particles stops completely. However, you can never actually cool something to this temperature because, in quantum mechanics, every particle has a minimum energy, called “zero-point energy,” which you cannot get below.

List of cat breeds The following list of cat breeds includes domestic cat breeds and domestic/wild hybrids. The list includes established breeds recognized by various cat registries, new and experimental breeds, distinct domestic populations not being actively developed and lapsed breeds. Inconsistency in breed classification among registries means that an individual animal may be considered different breeds by different registries. For example, The International Cat Association's Himalayan is considered a colorpoint version of the Persian by the Cat Fanciers' Association while the CFA's Javanese is considered a color variation of the Balinese by TICA. The domestic shorthair and domestic longhair are not breeds but terms used in cat fancy to describe cats that do not belong to a particular breed.
