The Allen Telescope Array The Allen Telescope Array (ATA) is a “Large Number of Small Dishes” (LNSD) array designed to be highly effective for simultaneous surveys undertaken for SETI projects (Search for Extraterrestrial Intelligence) at centimeter wavelengths. The initiative for building the ATA emerged from a series of workshops convened by the SETI Institute beginning in 1997. These workshops were charged with defining a path for future development of SETI technologies and search strategies. The SETI Institute sought private funds for such an instrument, and in 2001 Paul Allen (co-founder of Microsoft) agreed to fund the technology development and first phase of implementation, culminating in the construction of 42 antennas.
Planetary tilt could affect alien life Artist's rendition of the Milky Way's billions of planets. (credit: M. Kornmesser / ESO) An exciting announcement was made recently that suggests there could be billions of extraterrestrial-inhabited planets in our very own galaxy. A team of international scientists recently published findings in the journal Nature that conclude “stars are orbited by planets as a rule, rather than the exception,” and many of those are likely to be similar to Earth. The search for habitable planets and extraterrestrial life is gaining momentum, thanks largely to NASA’s planet-hunting space telescope Kepler. Artist's conception of Kepler-22b (credit: NASA/Ames/JPL-Caltech) Space.com reports that Heller and his colleagues recently published two papers describing how the gravitational interactions of stars and planets eventually erode the axial tilt of a planet.

Skynet University - Use Our Telescopes From Anywhere! Star trails, including the Large and Small Magellanic Clouds, over Skynet’s 32-inch diameter PROMPT-C7 telescope at Cerro Tololo Inter-American Observatory in the Chilean Andes. Skynet is a global network of fully automated, or robotic, telescopes serving professional astronomers, students of all ages — graduate through elementary school — and the public over the internet. Headquartered at the University of North Carolina (UNC) and funded primarily by the National Science Foundation, NASA, and private donations, Skynet’s telescopes span four continents. They have taken approaching 7 million images for tens of thousands of users. For the most part, access to Skynet is limited to the institutions that have contributed the telescopes (each ~$100K or more). Skynet University offers the same introductory astronomy courses that we have developed for our students at UNC to everyone everywhere. They include: Skynet University offers these courses online.

Hubble snaps stunning barred spiral galaxy image 3 February 2012Last updated at 09:35 NGC 1073 lies in the Cetus (a sea monster in Greek mythology) constellation The Hubble space telescope has captured an image of a "barred spiral" galaxy that could help us better understand our own Milky Way. Most of the known spiral galaxies fall into this "barred" category - which are defined by the pronounced bar structure across their centres. The presence of this structure may be an indication of a galaxy's age. Two-thirds of nearby galaxies have the bar, while only a fifth of more distant spirals have it. The new picture also continues the Hubble space telescope's long heritage of striking astronomical images. In the upper left of the image is a cluster showing recent star formation that is just visible to Hubble's cameras. But it is a bright source in X-ray light; astronomers believe that this IXO-5 X-ray source is actually a "binary" system comprising a star and a black hole in mutual orbit.

Flawless launch of Alphasat, Europe’s largest and most sophisticated telecom satellite / Alphasat / Telecommunications & Integrated Applications Ariane 5 liftoff with Alphasat Flawless launch of Alphasat, Europe’s largest and most sophisticated telecom satellite 25 July 2013 Alphasat, Europe’s largest and most sophisticated telecommunications satellite, was launched into its planned orbit today from Kourou, French Guiana. The Ariane 5 ECA rocket, operated by Arianespace, took off at 19:54 GMT, 21:54 CEST and delivered Alphasat into the target geostationary transfer orbit about 28 minutes later. Alphasat’s signal has been picked up by an Inmarsat ground station in Beijing as expected at 20:38 GMT (22:38 CEST), confirming that the satellite is at the predicted location, powered up and transmitting. Alphasat on Sylda Alphasat is a large telecommunications satellite primarily designed to expand Inmarsat’s existing global mobile network. All the partners were present at Europe’s Spaceport to watch the 6.6‑tonne satellite take off. Alphasat partners at Le Bourget Alphasat next to Alphabus platform Alphasat TDPs in Kourou
New "Super Earth" Found at Right Distance for Life A new planet—probably a rocky super-Earth—has been found squarely within its star's habitable zone, making it one of the best candidates yet to support life, its discoverers say. The planet, dubbed GJ 667Cc, orbits a red dwarf star 22 light-years from Earth, in the constellation Scorpio. A binary pair of orange dwarf stars are part of the same system. (Related: "'Tatooine' Planet With Two Suns Could Host Habitable Moon?") The new planet has a mass 4.5 times that of Earth and orbits its host star every 28 days. The red dwarf is relatively dim, so the planet receives slightly less light from its star than Earth does from the sun. That means if the planet has a rocky surface—which is predicted for planets less than ten times Earth's mass—and an atmosphere, it could support liquid water and maybe life, said co-discoverer Guillem Anglada-Escudé, who conducted the work while at the Carnegie Institution for Science in Washington, D.C.

Journal of Cosmology The long sought "grand theory of everything" must begin where there is no beginning and end where there is no ending: patterns which repeat themselves in nature and which give rise to infinite symmetry. Similar patterns are repeated from the micro-atomic to the macro-atomic, from snail shells to spiral galaxies. There is no reason to suspect these patterns end with individual galaxies. The symmetry and patterns exhibited by elementary particles, atoms, snail shells, sea shells, whirlpools, cyclones, solar systems, and spiral galaxies, should be applied to all galaxies, collectively, and to the cosmos. What these patterns have in common is they can be predicted from formulations first proposed by Pythagoras, and secondly, all orbit an eye or hole at their center. Key Words: Big Bang, Pythagoras, Black Holes, Symmetry, String Theory, Galaxies, Universe, Cosmos, These same principles can be applied to the genetic foundations of life, the structure of DNA, the double helix.

NASA Spacecraft Captures Sun's Year-End Outburst on Video | The Sun & Space Weather | Solar Flares & Coronal Mass Ejections The sun closed out 2011 with a flurry of activity, and a keen-eyed NASA spacecraft captured the dramatic outburst on video. NASA's Solar Dynamics Observatory (SDO) watched as our star erupted in dozens of storms during a 36-hour period on Dec. 29 and Dec. 30. The probe's stunning video, taken in extreme ultraviolet light, shows spouts of plasma and intense flashes of radiation blasting from the solar surface. "Magnetic forces were violently pulling against each other, creating the frenetic activity," SDO researchers wrote in an accompanying update. The recent outburst didn't produce any truly gargantuan storms. One medium-size flare is visible as a bright white flash about halfway through the new video. CMEs that hit Earth can wreak havoc on our planet, causing temporary disruptions in GPS signals, radio communications and power grids. It's not terribly suprising that the sun ended the year with a bang, because it had a very active 2011.

Types of Stars Want to stay on top of all the space news? Follow @universetoday on Twitter Red giant Betelgeuse. Image credit: Hubble Space Telescope A star is a star, right? Protostar A protostar is what you have before a star forms. T Tauri Star A T Tauri star is stage in a star’s formation and evolution right before it becomes a main sequence star. Main Sequence Star The majority of all stars in our galaxy, and even the Universe, are main sequence stars. A star in the main sequence is in a state of hydrostatic equilibrium. The lower mass limit for a main sequence star is about 0.08 times the mass of the Sun, or 80 times the mass of Jupiter. Red Giant Star When a star has consumed its stock of hydrogen in its core, fusion stops and the star no longer generates an outward pressure to counteract the inward pressure pulling it together. Red Dwarf Star Red dwarf stars are the most common kind of stars in the Universe. Supergiant Stars The largest stars in the Universe are supergiant stars.
