A new theory from scientists at Harvard University posits that atmospheric sulfur resulting from volcanic activity may have led to the Earth’s first and largest ever planetary freezing. Continue reading
New images released taken by NASA’s New Horizons spacecraft indicate two of Pluto’s most distinctive mountains could be cryovolcanoes.
NASA’s Cassini spacecraft transmits images of Saturn’s icy, geologically active moon Enceladus, acquired during a dramatic flyby in which the probe passes about 30 miles (49 kilometers) above the moon’s south polar region.
NASA released a new animation of a flyover of Pluto on Saturday (September 19) that was created from a mosaic of hundreds of pictures taken by the New Horizons spacecraft as it observed Pluto in mid-July.
Stuart Robbins, a research scientist at the Southwest Research Institute in Boulder, Colorado, said on NASA’s website he made the animation using images of Pluto sent by New Horizons because he likes to figure out “how to make visualizations that convey some of the sheer beauty and power of the features New Horizons is revealing.”
(NASA TV) – Robbins says he primarily uses the New Horizon images to map craters on the surface of Pluto and its largest moon, Charon, to get a better understand of the number of impacts the orbital spheres receive from the Kuiper belt.
NASA confirms that a moon orbiting Jupiter has an ocean beneath its icy surface.
