46 Fabulous Photos of Endeavour’s Last Ever Spacewalk

46 Fabulous Photos of Endeavour’s Last Ever Spacewalk May 27th, 2011: the last spacewalk for NASA’s Endeavour astronauts. Here, a fish-eye lens attached to an electronic still camera was used to capture this image of NASA astronaut Michael Fincke (top center) during the mission’s fourth session of extravehicular activity (EVA) as construction and maintenance continued on the International Space Station.

Interactive 3D model of Solar System Planets and Night Sky

Description 3D simulation of the Solar System and night sky in real time - the Sun, planets, dwarf planets, comets, stars and constellations. - Heliocentric view with real-time positions of planets and planetary orbits - Schematic and realistic sizes of the planets and distances between them - Movement of the planets in time to see how they move in relation to each other - Virtual Orrery - Planetary exploration with info texts and additional views such as structure - Dwarf planets (Pluto, Ceres, Haumea, Makemake. Eris) and their orbits - Comets (Siding Spring, Lovejoy 2013, Lovejoy 2011, Panstarrs, ISON, Halley) - positions and trajectories - Stars and constellation of the night sky as viewed from a given location - Changes in the night sky during night, month and year - Searching of the stars and constellation, ecliptic line, grid lines and more
