Mapping Voyager 1's Incredible 36-Year Mission Through Space [INFOGRAPHIC]
Voyager 1 spacecraft's biggest moments are shown in this chart covering the last 36 years... Voyager 1 is almost 12 billion miles away now! and moving at 36,000 miles per hour!...Voyager 1 will be the first ever object we've sent outside our solar system.
Dark, cold & whipped by supersonic winds, Neptune is a hydrogen & helium gas giant in our solar system. Over 30 times as far from the sun as Earth, it takes almost 165 Earth years to orbit our sun. In 2011, Neptune completed its first orbit since its discovery in 1846. On Neptune, one "day" (time it takes to rotate once on its axis) takes 16 hours. It makes a complete orbit @ the sun in 165 Earth years. It has 13 moons & 6 rings. Photo: the "sideways" planet with vertically orbiting rings <3
O mundo que nós conhecemos e todo o universo em torno dele pode estar cercado de uma densa e (quase) onipresente matéria escura, da qual inclusive cerca de 27% de todo o cosmo é feito. Pesquisas recentes divulgadas pela Nasa na imprensa britânica mostram que filamentos gigantes dessa substância negra estão concentrados em torno de corpos celestes, como a Terra ou Marte.
Mount Sharp is still far away! (Full: http://flic.kr/p/hgADxx) - It would be nice to have 360 panoramas with a lot more sky... almost on top of the head! Curiosity, can you do it at least once? - "Courtesy NASA/JPL-Caltech" processing 2di7 & titanio44
The Great Divide (NASA Cassini Saturn Mission Image) The 2,980-mile-wide (4,800-kilometer-wide) division in Saturn's rings is thought to be caused by the moon Mimas. Particles within the division orbit Saturn almost exactly twice for every time that Mimas orbits, leading to a build-up of gravitational nudges from the moon. These repeated gravitational interactions sculpt the outer edge of the B ring and keep its particles from drifting into the Cassini Division.
