  • Landsat’s Orbit

    Landsat’s Orbit

    Jim Irons, the Project Scientist at NASA’s Goddard Space Flight Center tells you how long it takes for Landsat 8 to orbit the Earth and view the full surface of the globe. As a Landsat satellite flies over the surface of the Earth the instruments aboard the satellite are able to view a swath 185 kilometers wide and collect images along that swath as the satellite proceeds through its orbit. The spacecraft travels at approximately 4.7 miles per second. The […]

  • Saturn’s Auroras Dance!

    Saturn’s Auroras Dance!

    Saturn’s auroras glow when energetic electrons dive into the planet’s atmosphere. Sometimes a blast of fast solar wind creates an active aurora at Saturn,as occurred on April 5 and May 20, 2013. Ultraviolet and infrared images from NASA’s Cassini spacecraft and Hubble Space Telescope show active and quiet auroras at Saturn’s north and south poles. Saturn’s auroras glow when energetic electrons dive into the planet’s atmosphere and collide with hydrogen molecules. Sometimes a blast of fast solar wind, composed of […]

  • Servicing Satellites In Space

    Servicing Satellites In Space

    In this video, robotic arm operator Alex Janas introduces RROxiTT (Remote Robotic Oxidizer Transfer Test) while standing next to the robotic arm. He also teases an upcoming, longer video that will go into further detail and show footage from the actual test. NASA’s Goddard Space Flight Center in Maryland and Kennedy Space Center in Florida are joining teams and efforts to test new robotic refueling technologies that could help satellites live longer in space. During the test, a robotic arm […]

  • Youngest Galaxy And Oldest Star!

    Youngest Galaxy And Oldest Star!

    Trace Dominguez summarizes this big week in astronomy. Astronomers found both the oldest star we’ve ever seen, and also the youngest galaxy. Both were formed just after the Big Bang occurred 13 billion years ago, and Trace is here to tell you what these two findings can teach us about the origins of everything! Enjoy and share….

  • How Earth Avoided The Grim Fate Of Venus

    How Earth Avoided The Grim Fate Of Venus

    We can see the answer as the solar storm approaches Earth.Our planet has a magnetic shield to protect it.In fact this magnetic shield is our first line of defense,much of the solar energy that gets through is deflected back to space by clouds,ice and snow. Watch Earth’s magnetic shield protect the planet from a pelting by the solar wind. See how the sun’s energy drives a remarkable planetary engine, the climate. This video, originally created by NASA’s Scientific Visualization Studio […]

  • The Structure Of Dark Matter

    The Structure Of Dark Matter

    The Universe is becoming less of a mystery as time goes by. In this video Dr J explains how dark matter is structured. Here you will find the full article by SpaceRip posted with this video. Astronomers using the NASA/ESA Hubble Space Telescope have studied a giant filament of dark matter in 3D for the first time. Extending 60 million light-years from one of the most massive galaxy clusters known, the filament is part of the cosmic web that constitutes […]

  • A Comet Heads For Mars

    A Comet Heads For Mars

    Comet 2013A1 Over the years we have sent dozens of probes and rovers to explore Mars. Today there are 3 active satellites circling Mars,Mars Reconnaissance Orbiter,Mars Odyssey and Mars Express.Meanwhile 2 Rovers wheel on the Mars’s red soil below. The solar powered Rover Opportunity and the nuclear powered Curiosity. A comet is heading for Mars, and there is a chance that it might hit the Red Planet in October 2014. An impact wouldn’t necessarily mean the end of NASA’s Mars […]
