Humanity’s robot orbiting Saturn has recorded yet another amazing view. That robot, of course, is the spacecraft Cassini, while the new amazing view includes a bright moon, thin rings, oddly broken clouds, and warped shadows. Titan, Saturn’s largest moon, appears above as a featureless tan as it is continually shrouded in thick clouds. The rings […]
As its June 6 2012 transit begins Earth’s sister planet crosses the edge of the Sun in this stunning view from the Hinode spacecraft. The timing of limb crossings during the rare transits was used historically to triangulate the distance to Venus and determine a value for the Earth-Sun distance called the astronomical unit. … […]
This dramatic telephoto view across the Black Sea on June 6 finds Venus rising with the Sun, the planet in silhouette against a ruddy and ragged solar disk. Of course, the reddened light is due to scattering in planet Earth’s atmosphere and the rare transit of Venus didn’t influence the strangely shaped and distorted Sun. […]
We’re not supposed to look directly at the sun and surprisingly, the Hubble space telescope can’t either. The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency. NASA’s Goddard Space Flight Center in Maryland manages the telescope. An exciting event is about to occur: “the transit of Venus,” […]
When making its closest pass yet of Saturn’s moon Dione late last year, the robotic Cassini spacecraft snapped this far-ranging picture featuring Dione, Saturn’s rings, and the two small moons Epimetheus and Prometheus. The above image captures part of the heavily cratered snow-white surface of the 1,100 kilometer wide Dione, the thinness of Saturn’s rings, […]
By Dan Nosowitz The Russian Soyuz TMA-21 spacecraft, carrying three astronauts (Commander Andrei Borisenko and Alexander Samokutyayev, both Russian, and American Ron Garan) safely landed this morning in Kazakhstan, bringing them home after five months on the International Space Station. The landing, about 94 miles southeast of the smallish Kazakh city Zhezkazgan, wasn’t entirely flawless–mission control […]
A mournful French horn blows. An angsty Luke Skywalker stomps out of his aunt and uncle’s sand hut and peers up at Tatooine’s double sunset, his hair blowing in the breeze. It’s a memorable scene from Star Wars—but now, a precedent for such a sky with two suns has been found in our universe. Using […]
An American ‘armchair astronaut’ claims to have discovered a mysterious structure on the surface of the red planet – by looking on Google earth. David Martines, whose YouTube video of the ‘station’ has racked up over 200,000 hits so far, claims to have randomly uncovered the picture while scanning the surface of the planet one […]
A tiny world of molten rock, orbiting scorchingly close to its host star, is the smallest planet ever discovered outside our solar system, NASA announced today. And it’s likely only the first in a parade of planet discoveries to be announced this spring by the Kepler Space Telescope team. Kepler-10b, as the new world is […]
Astronomers have been busy trying to determine the spin period and composition of Venus‘ moon. December 8, 2010, results were announced by JPL/Caltech scientists, led by Michael Hicks. “Wait a minute; back up”, I hear you ask. “Venus has a Moon?” Of course it does. Well, kind of… Let me explain. It has […]
