A new book brings together breathtaking photos taken by Apollo astronauts, many of which were previously unpublished.

Not a Falcon 9 rocket launch after sunset, the Cat's Eye Nebula (NGC 6543) is one of the best known planetary nebulae in the sky. Its haunting symmetries are seen in the very central region of this composited picture, processed to reveal an enormous but extremely faint halo of gaseous material, over three light-years across. Made with data from ground- and space-based telescopes it shows the extended emission which surrounds the brighter, familiar planetary nebula. Planetary nebulae have long been appreciated as a final phase in the life of a sun-like star. But only more recently have some planetaries been found to have halos like this one.

Jupiter looks a bit different in ultraviolet light. To better interpret Jupiter's cloud motions and to help NASA's robotic Juno spacecraft understand the planetary context of the small fields that it sees, the Hubble Space Telescope is being directed to regularly image the entire Jovian giant. The colors of Jupiter being monitored go beyond the normal human visual range to include both ultraviolet and infrared light.

First came the trees. In the town of Salamanca, Spain, the photographer noticed how distinctive a grove of oak trees looked after being pruned. Next came the galaxy.

By combining the power of four telescopes, an international team of astronomers has captured the most detailed image yet of a distant star—an observation that’s meshing well with pre-existing theories about the physical characteristics of giant stars.

Bright dots that look like snow are in fact stars.

On March 13, 2006 Cassini's narrow-angle camera captured this look at Saturn and its rings, seen here nearly edge on. The frame also features Mimas and tiny Janus (above the rings), and Tethys (below the rings). "Above" and "below" the rings is mostly a matter of perspective here. All three moons and the rings orbit Saturn in roughly the same plane.

One Day a Year… for the Salad. Yeah. John De Crevecouer Go for it.

After a more than nine-year, three-billion-mile journey to Pluto, it’s show time for NASA’s New Horizons spacecraft, as the flyby sequence of science observations is officially underway. In the early morning hours of July 8, mission scientists received this new view of Pluto—the most detailed yet returned by the Long Range Reconnaissance Imager (LORRI) aboard New Horizons. The image was taken on July 7, when the spacecraft was just under 5 million miles (8 million kilometers) from Pluto.

If you gaze long enough into space, space will gaze back into you

Doesn't look much different than a desert on Earth.

These clouds - sometimes called night-shining clouds - are thought to be made of ice crystals that form on fine dust particles from meteors.

M2 is a globular cluster located in the constellation Aquarius.

There's many star trail pics out there, but this is the first panoramic one I've seen.

On July 11, 2015, New Horizons captured this image, which suggests some new features that are of keen interest to the Geology, Geophysics and Imaging (GGI) team now assembled at the Johns Hopkins University Applied Physics Lab in Laurel, Maryland. For the first time on Pluto, this view reveals linear features that may be cliffs, as well as a circular feature that could be an impact crater.

It doesn't look that red in this pic. Changes color every now and then.

NASA said it was giving Instagram an hour-long head start on the first image, posting it to the social media service before officially releasing it on its public website.

“Hello #Pluto! We’re at closest approach. Congrats to all! Follow our story & view new images using #PlutoFlyby.”

Pluto is a dwarf planet now, but pluto has a heart and still loves us. New Horizons saw pluto's love for us today
