YouTube - Asteroid Discovery From 1980 - 2010 - 1 views

  •  
    "View of the solar system showing the locations of all the asteroids starting in 1980, as asteroids are discovered they are added to the map and highlighted white so you can pick out the new ones. The final colour of an asteroids indicates how closely it comes to the inner solar system. Earth Crossers are Red Earth Approachers (Perihelion less than 1.3AU) are Yellow All Others are Green Notice now the pattern of discovery follows the Earth around its orbit, most discoveries are made in the region directly opposite the Sun. You'll also notice some clusters of discoveries on the line between Earth and Jupiter, these are the result of surveys looking for Jovian moons. Similar clusters of discoveries can be tied to the other outer planets, but those are not visible in this video. As the video moves into the mid 1990's we see much higher discovery rates as automated sky scanning systems come online. Most of the surveys are imaging the sky directly opposite the sun and you'll see a region of high discovery rates aligned in this manner. At the beginning of 2010 a new discovery pattern becomes evident, with discovery zones in a line perpendicular to the Sun-Earth vector. These new observations are the result of the WISE (Widefield Infrared Survey Explorer) which is a space mission that's tasked with imaging the entire sky in infrared wavelengths. Currently we have observed over half a million minor planets, and the discovery rates snow no sign that we're running out of undiscovered objects. Orbital elements were taken from the 'astorb.dat' data created by Ted Bowell and associates at http://www.naic.edu/~nolan/astorb.html"

CBC News - Technology & Science - 2 asteroids fly near Earth - 0 views

  •  
    "One transport truck-sized asteroid passed the Earth Wednesday morning and another will soar by in the afternoon, with both far closer to the planet than the moon. There is no danger of the Earth being hit and both should be visible with moderate-sized amateur telescopes, NASA reported."

Newly discovered planet may be first truly habitable exoplanet - UC Santa Cruz - 0 views

  •  
    "A team of planet hunters led by astronomers at the University of California, Santa Cruz, and the Carnegie Institution of Washington has announced the discovery of an Earth-sized planet (three times the mass of Earth) orbiting a nearby star at a distance that places it squarely in the middle of the star's "habitable zone," where liquid water could exist on the planet's surface. If confirmed, this would be the most Earth-like exoplanet yet discovered and the first strong case for a potentially habitable one."

YouTube - Bill Nye - Greatest Discoveries - 4: Geology - 0 views

  •  
    Bill Nye and the Discovery Channel give you the greatest discoveries in science. Earth is always changing, and Earth's species must continually adapt. Host Bill Nye gives an inside look at planet Earth, from its inner core to its protective magnetic field. Discover how earthquakes and volcanoes help explain plate tectonics and the dynamic geology of oceans and continents. Learn how the Earth's atmosphere gives scientific insight about weather and climate, and look at forms of radiation and the potential dangers from harmful gases and geologic changes.

BBC News - Super-Earths 'in the billions' - 1 views

  •  
    "Harps employs an indirect method of detection that infers the existence of orbiting planets from the way their gravity makes a parent star appear to twitch in its motion across the sky. "Our new observations with Harps mean that about 40% of all red dwarf stars have a super-Earth orbiting in the habitable zone where liquid water can exist on the surface of the planet," said team leader Xavier Bonfils from the Observatoire des Sciences de l'Univers de Grenoble, France. "Because red dwarfs are so common - there are about 160 billion of them in the Milky Way - this leads us to the astonishing result that there are tens of billions of these planets in our galaxy alone.""

Artificial cooling of Earth could reverse global warming - Technology & Science - CBC News - 0 views

  •  
    "A report released late Thursday in London and discussed Friday at the U.N. climate conference in South Africa said that - in theory - reflecting a small amount of sunlight back into space before it strike's the Earth's surface would have an immediate and dramatic effect. Within a few years, global temperatures would return to levels of 250 years ago, before the industrial revolution began dumping carbon dioxide into the air, trapping heat and causing temperatures to rise."
