Why this matters

This scene highlights near-Earth objects, the night sky. The same physics that lets us photograph it also lets us predict where objects will be tomorrow — which is exactly what real-time tracking is built on.

This connects to what you can track in real time on our 3D globe — explore Asteroid tracker · Deep Space. Or open the live globe to watch flights, satellites, the ISS and spacecraft move right now.

The science, from NASA's Astronomy Picture of the Day

Put on your red/blue glasses and float next to the jagged and double-lobed nucleus of Churyumov-Gerasimenko, also known as Comet 67P . The stereo anaglyph was created by combining two images from the Rosetta spacecraft's narrow angle OSIRIS camera taken on July 25, 2015 from a distance of 184 kilometers. Numerous jets are emanating from the small solar system world's active surface near its closest approach to the Sun. The larger lobe is around 4 kilometers in diameter, joined to a smaller, 2.5 kilometer diameter lobe by a narrow neck. Rosetta's mission to the comet ended in September 2016 when the spacecraft was commanded to a controlled impact with the comet's surface . Keep those 3D glasses on though. You can check out a catalog of nearly 1400 stereo anaglyphs created from Rosetta image data on this website.Tomorrow's picture: open space
