Google’s new Earth Engine, powered by NASA’s landsat satellites, gives a time lapse view of (pretty much) every land surface on earth over the last 25 years. The view is amazing, and inspiring, and at times terrifying. Hank Green reports.
This 4k video features some of the most astonishingly beautiful images from the Gateway to Astronaut Photography based at NASA’s Johnson Space Center. How can anyone ever tire of gazing on the gentle curvature of mother Earth as seen from the International Space Station.
Hank Green has some good news about NASA, which has now been assigned a new mission to capture an asteroid.
While you can’t look directly into the sun without damaging your eyes, the Solar Dynamics Observatory posts a dazzling array of solar images on its website. Alex Dainis of Bite Sci-zed offers an overview of what you’ll find if you visit http://sdo.gsfc.nasa.gov/
A new study using observations from NASA’s Fermi Gamma-ray Space Telescope reveals the first clear-cut evidence that the expanding debris of exploded stars produces some of the fastest-moving matter in the universe. This discovery is a major step toward meeting one of Fermi’s primary mission goals. H/T SpaceRip
Calling Bruce Willis.
This coming Friday, a 130,000-ton asteroid is set to pass perilously close to Earth. NASA has been tracking the asteroid and believes it won’t strike the planet. But what if NASA is wrong about this projectile, known as 2012 DA14? Robert Lee Hotz from The Wall Street Journal runs down what you need to know.
Meanwhile, new evidence has emerged that another asteroid — although a much larger one — wiped out the dinosaurs.
Conspiracy theorists still allege that astronauts never landed on the Moon, that NASA staged the spectacle in a TV studio. But, in reality, video technology was too primitive in the 1960s to orchestrate such an elaborate hoax. Watch and learn. H/T IMAO
Astronaut Jerry Carr knows space. As commander of Skylab, he spent more than 2,000 hours in space, orbiting the Earth over 1,000 times. Recounting his life story, Carr remembers the enchanting years he spent at NASA in an animated video from TEDEducation.
NASA has beamed a digitalized image of Leonardo Da Vinci’s painting Mona Lisa to the Moon and beyond into space. The transmission was used to test long-range laser communication systems, which could someday overtake radio and allow for HD streaming from deep space. But in the event aliens receive the broadcasts, should we be sending the docile and smiling Mona Lisa or perhaps a more fierce icon, say, Sheena Queen of the Jungle?
Composer Robert Alexander is helping NASA make new discoveries by turning raw data into music through a process called Data Sonification. Alexander, a classically trained composer, charts the sun’s cycles and patterns, transcribing the data into audio equivalents that he uses as the basis for his music.
