This photo was taken on July 11, 2011. Neptune's happy anniversary! It's taken Neptune a whole year to make an orbit around the sun...but that's a Neptune year of 165 Earth years! Read more below, and I also wanted to share this great link from Goddard Space Flight Center: www.nasa.gov/mission_pages/hubble/science/neptune-circuit....
Gravity bends more than just space. It bends time. The early results from Gravity Probe B, one of NASA’s most complicated satellites, confirmed ‘to a precision of better than 1 per cent’ the assertion Einstein made 90 years ago - that a massive object such as the Earth does indeed distort the fabric of space and time. This explains why GPS satellites must correct for time distortion: it passes more quickly in orbit than on the Earth.
A binary black hole system, viewed edge-on. This pair of extremely dense objects twists and warps spacetime as the two black holes spiral in toward one another.

M81 by nasa.gov: This lovely spiral galaxy's arms curl all the way down into its center. It is one of the brightest galaxies that can be seem from earth and is located 12 million light-years away in the Ursa Major constellation.
