Die NASA hat aus denn Orbits des Fermi Gamma-ray Space Telescopes eine Spirograph-artige Bewegungsstudie gebastelt. Toll, ich liebe Spirographs.
NASA's Fermi Gamma-ray Space Telescope orbits our planet every 95 minutes, building up increasingly deeper views of the universe with every circuit. Its wide-eyed Large Area Telescope (LAT) sweeps across the entire sky every three hours, capturing the highest-energy form of light -- gamma rays -- from sources across the universe. […] Now a Fermi scientist has transformed LAT data of a famous pulsar into a mesmerizing movie that visually encapsulates the spacecraft's complex motion.
Pulsars are neutron stars, the crushed cores of massive suns that destroyed themselves when they ran out of fuel, collapsed and exploded. The blast simultaneously shattered the star and compressed its core into a body as small as a city yet more massive than the sun. One pulsar, called Vela, shines especially bright for Fermi. It spins 11 times a second and is the brightest persistent source of gamma rays the LAT sees.
Bonustrack: Ich hab' vor einer Weile irgendwo ein paar alte Spirograph Packaging Bilder aufgegabelt, die gibt's nach dem Klick.
