H-ATLAS J142935.3-002836, an object seen by the Hubble Space Telescope and the Keck-II telescope on Hawaii with the help of a gravitational lens. In this image one can see the foreground galaxy that is doing the lensing, which resembles how our Milky Way Galaxy would appear if seen edge-on; but around this galaxy there is an almost complete ring - the smeared out image of a star-forming galaxy merger far beyond.

This false-color mosaic, made from infrared data collected by NASA's Cassini spacecraft, reveals the differences in the composition of surface materials around hydrocarbon lakes at Titan, Saturn's largest moon. Titan is the only other place in the solar system that we know has stable liquid on its surface, though its lakes are made of liquid ethane and methane rather than liquid water. While there is one large lake and a few smaller ones near Titan's south pole, almost all of Titan's lakes appear near the moon's north pole.
