Eta Carina
NASA’s New Horizons spacecraft took this stunning image of Pluto only a few minutes after closest approach on July 14, 2015. The image was obtained at a high phase angle –that is, with the sun on the other side of Pluto, as viewed by New Horizons. Seen here, sunlight filters through and illuminates Pluto’s complex atmospheric haze layers. The southern portions of the nitrogen ice plains informally named Sputnik Planum, as well as mountains of the informally named Norgay Montes, can also be seen across Pluto’s crescent at the top of the image.

SEMPER PARATUS ALWAYS READY The Coast Guard Marching Song (sheet music)
Space tourism is still a ways off, but NASA, everybody’s favorite government agency, released some pretty sweet posters for destinations you’ll (hopefully!) be able to visit someday.
See the full NASA collection over at their website.

It might sound like science fiction, but we already know how to make objects move at near light speed. Physicists do it all the time inside particle accelerators, where they accelerate particles to relativistic speeds just a small fraction below the speed of light (about 186,000 miles per second).
But when we try to reach these speeds on a macro scale, we run into all kinds of problems. Now researchers are saying a new kind of laser-based propulsion would eliminate the need for fuel and could accelerate spacecraft up to 26% of the speed of light. At that blistering pace, a tiny space probe could get to Mars in just 30 minutes. The technology to make it happen already exists.
