This image shows conditions observed by Cassini during a flyby on December 1, 2013, when the magnetosphere of Saturn was highly compressed, exposing Titan to the full force of the solar wind. In analyzing data from the encounter, the researchers observed that the moon interacted with the solar wind much like the planets Mars and Venus, or a comet. Specifically, they saw that the solar wind draped itself around Titan, creating a shockwave that formed around Titan where the full-force solar wind rammed into the atmosphere of the moon. Previously, scientists had thought Titan would have a different sort of interaction with the solar wind because of the complex atmospheric chemistry of the moon. Image credit: NASA / JPL-Caltech.

This is an artist's concept of NASA's New Horizons during its planned encounter with Pluto and its moon, Charon: the craft's miniature cameras, radio science experiment, ultraviolet and infrared spectrometers and space plasma experiments would characterize the global geology and geomorphology of Pluto and Charon, map their surface compositions and temperatures, and examine Pluto's atmosphere in detail; the spacecraft's most prominent design feature is a nearly 2.1-m dish antenna, through which it would communicate with Earth from as far as 7.5 billion km away.

Hot stars burn brightly in this image from NASA's Galaxy Evolution Explorer, showing the UV side of a familiar face. At 2.5 million light-years away, the Andromeda galaxy is our Milky Way's largest galactic neighbor. The galaxy spans 260,000 light-years across. The bands of blue-white making up the galaxy's striking rings are neighborhoods that harbor hot, young, massive stars. Dark blue-grey lanes of cooler dust show up starkly against these bright rings, tracing the regions where star formation is currently taking place in dense cloudy cocoons. Eventually, these dusty lanes will be blown away by strong stellar winds, as the forming stars ignite nuclear fusion in their cores. Meanwhile, the central orange-white ball reveals a congregation of cooler, old stars that formed long ago. When observed in visible light, the galaxy’s rings look more like spiral arms. The UV image shows that these arms more closely resemble the ring-like structure previously observed in infrared wavelengths with NASA’s Spitzer Space Telescope; astronomers interpreted these rings as evidence that the galaxy was involved in a direct collision with its neighbor, Messier 32, more than 200 million years ago.
