  • Astronomy DVD Astronomy DVD essentials: - ======================= A large number of astronomy DVDs contain images, videos, and fascinating facts about the universe. If you are enthusiastic about astronomy or if your kids are enthusiastic about astronomy, how would you select an interesting astronomy DVD that educates and entertains at the same time, given the vast choice of DVDs that are available on the topic of astronomy? Here are the top 3 features of a great astronomy DVD that you might want to consider: - 1.) Genuine Astronomy Data and Images ================================ The first thing to consider is the genuineness of the images and astronomical data on the DVD. Space exploration missions of NASA and ESA, the Hubble Telescope, and other unmanned deep space probes have collected vast amounts of fascinating information about the Universe. The representation of the Universe on any interesting astronomy DVD is based not only on real and high resolution images of the celestial bodies, but also on the precise positions, motions, and luminosity of the celestial bodies. Between 1989 and 1993, European Space Agency's "Hipparcos Project" (High Precision Parallax Collection Satellite Astrometric and Photometric Project) pinpointed the accurate positions, motions, and luminosity of over 100000 stars and heavenly bodies. A good DVD about astronomy uses this data to create a realistic representation of the heavenly bodies in time and space. 2.) Guided Virtual Tours ...

  • Direct Image Of Extrasolar Planet NASA's Hubble Space Telescope has taken the first visible-light snapshot of a planet circling another star. Estimated to be no more than three times Jupiter's mass, the planet, called Fomalhaut b, orbits the bright southern star Fomalhaut, located 25 light-years away in the constellation Piscis Australis, or the "Southern Fish." Fomalhaut has been a candidate for planet hunting ever since an excess of dust was discovered around the star in the early 1980s by NASA's Infrared Astronomy Satellite, IRAS. In 2004, the coronagraph in the High Resolution Camera on Hubble's Advanced Camera for Surveys produced the first-ever resolved visible-light image of the region around Fomalhaut. It clearly showed a ring of protoplanetary debris approximately 21.5 billion miles across and having a sharp inner edge. This large debris disk is similar to the Kuiper Belt, which encircles the solar system and contains a range of icy bodies from dust grains to objects the size of dwarf planets, such as Pluto. Hubble astronomer Paul Kalas, of the University of California at Berkeley, and team members proposed in 2005 that the ring was being gravitationally modified by a planet lying between the star and the ring's inner edge. Circumstantial evidence came from Hubble's confirmation that the ring is offset from the center of the star. The sharp inner edge of the ring is also consistent with the presence of a planet that gravitationally "shepherds" ring particles. Independent researchers have ...

  • UPDATE 2009 BD NEO Near Earth Object Asteroid Has Solar Radiation My Be From Moon 2009 BD was discovered on January 16, 2009 by the Mt. Lemmon Survey in Arizona. This object has an absolute magnitude of only 28.3, suggesting a diameter of roughly 10 meters. It's notable because it remains close to Earth for months at a time and is actually a co-orbital object with a very low delta-V relative to Earth. As such, its origin is of acute scientific interest. A recurring question about objects with very low delta-V values is whether they may be ejecta from the Moon. Recent work by Micheli, Tholen, and Elliott (2011 Planetary Defence Conference) indicates that solar radiation pressure has been detected for this object, one of the first instances where that has occurred. If we detect it with radar, our constraints on the object's size coupled with the radiation pressure detection could be used to estimate the asteroid's mass and bulkd density, information that is very important but unavailable for the vast majority of near-Earth objects. 2009 BD will approach within 0.0023 AU (~0.90 lunar distances) on June 2, 2011, and will remain within 10 lunar distances of Earth for two months starting in early May. Due to the close approach, 2009 BD should be a strong radar target, and the short round-trip travel times will require us to observe bistatically by transmitting with DSS-14 and receiving with DSS-13. Other than its absolute magnitude, nothing is known about the physical properties of this object. 2009 BD will remain too close to the Sun for optical ...
  • All Your Sins This faint audio-visual signal was detected at the approximate location of the Colonial Federal Emergency Administration GHQ on St. Arke, Luna. While Sol and the contents of it no longer exist, the transmission persists from the same volume of empty space. Via astrometric logs, we can determine that the position of Luna based on the point of transmission was its orbit at approximately midnight FST, June 12, 2633. The landscape depicted in the video, however, does not match up to any known colonial terrain. Additionally, the corpse in the footage appears to be that of former TCF President John Mikhailovich, though his last known location was before cameras at the CFEA GHQ on St. Arke - nowhere near the desert depicted in this video. The armored vehicles behind him appear of no known make or model, and the supports and lights below him are of an unknown source. There is no obvious evidence of editing or VGUI simulation of the image, leaving the ultimate setting of this gruesome video a mystery. The message, however, is altogether clear.

  • Gaia The main goal of the Gaia mission is to make the largest, most precise three-dimensional map of our Galaxy by surveying an unprecedented one per cent of its population of 100 billion stars. During the mapping, Gaia will detect and very accurately measure the motion of each star in its orbit around the centre of the Galaxy. Much of this motion was imparted upon each star during its birth and studying it allows astronomers to peer back in time, to when the Galaxy was first forming. By constructing a detailed map of the stars, Gaia will provide a crucial tool to study the formation of our Galaxy, the Milky Way. While surveying the sky, Gaia is bound to make many other discoveries. During its anticipated lifetime of five years, Gaia will observe each of its one billion sources about 100 times, resulting in a record of the brightness and position of each source over time. Together with the unprecedented accuracy of the astrometric measurements, this will lead to the discovery of: planets around other stars, asteroids in our Solar System, icy bodies in the outer Solar System, brown dwarfs, and far-distant supernovae and quasars. The list of Gaia's potential discoveries makes the mission unique in scope and scientific return.
