A gorgeous shot of #Arches National Park in #Utah! James Shoemaker captured this unique shot of #DelicateArch -- one of the most photographed sites in the park. "When you enter Arches #NationalPark for the first time, you cannot be prepared for the grandeur of the rock formations, especially Delicate Arch," James says. by usinterior

In Green Company: Aurora over Norway In Green Company: Aurora over Norway
Raise your arms if you see an aurora. With those instructions, two nights went by with, well, clouds -- mostly. On the third night of returning to same peaks, though, the sky not only cleared up but lit up with a spectacular auroral display. Arms went high in the air, patience and experience paid off, and the amazing featured image was captured. The setting is a summit of the Austnesfjorden fjord close to the town of Svolvear on the Lofoten islands in northern Norway. The time was early March. Our Sun has been producing an abundance of picturesque aurora of late as it is near the time of its maximum surface activity in its 11-year magnetic cycle. via NASA http://ift.tt/1t5DMaz

November is #ManateeAwarenessMonth! Pictured here is a #manatee at the Three Sisters Springs in Crystal River National #WildlifeRefuge Complex. This #Florida refuge was established in 1983 specifically for the protection of the endangered West Indian manatee. #CrystalRiver refuge preserves the warm water spring havens, providing critical habitat for the manatee populations that migrate here each winter.

A beautiful #sunrise on a fall morning at #GreatFalls Park. Located just 15 miles outside of Washington, D.C., the park is best known for its series of falls that are created as the Potomac River flows over steep, jagged rocks and through a narrow gorge.

Titan Beyond the Rings Titan Beyond the Rings
When orbiting Saturn, be sure to watch for breathtaking superpositions of moons and rings. One such picturesque vista was visible recently to the robot Cassini spacecraft now orbiting Saturn. In 2006 April, Cassini captured Saturn's A and F rings stretching in front of cloud-shrouded Titan. Near the rings and appearing just above Titan was Epimetheus, a moon which orbits just outside the F ring. The dark space in the A ring is called the Encke Gap, although several thin knotted ringlets and even the small moon Pan orbit there. via NASA http://ift.tt/1wTn18w

The Day After Mars The Day After Mars
October 31, 1938 was the day after Martians encountered planet Earth, and everything was calm. Reports of the invasion were revealed to be part of a Halloween radio drama, the now famous broadcast based on H.G. Wells' scifi novel War of the Worlds. On Mars October 20, 2014 was calm too, the day after its close encounter with Comet Siding Spring. Not a hoax, this comet really did come within 86,700 miles or so of Mars, about 1/3 the Earth-Moon distance. Earth's spacecraft and rovers in Mars orbit and on the surface reported no ill effects though, and had a ringside seat as a visitor from the outer solar system passed by. Spanning over 2 degrees against stars of the constellation Ophiuchus, this colorful telescopic snapshot captures our view of Mars on the day after. Bluish star 51 Ophiuchi is at the upper right and the comet is just emerging from the Red Planet's bright glare. via NASA http://ift.tt/1s2Buda

Milky Way over Devils Tower Milky Way over Devils Tower
A mysterious formation known as Devils Tower rises into the dark above northeastern Wyoming's prairie landscape in this 16 frame panoramic view. Seen against the night sky's thin, pale clouds and eerie green airglow, star clusters and nebulae of the Milky Way arc toward the galaxy's central realm at right. Of course the scene contains the Milky Way's own haunting and grisly visages of halloween, including ghosts, a flaming skull, a glowing eye and a witch's broom. To find them, slide your cursor over the picture or just follow this link, if you dare. And have a safe and Happy Halloween! via NASA http://ift.tt/1zPvpcL
