Dr. Ellen Ochoa on the Flight Deck of Shuttle Atlantis #NASA

On April 15, 2002, STS-110 Mission Specialist Ellen Ochoa works at the Remote Manipulator System controls on the aft flight deck of space shuttle Atlantis. Dr. Ochoa, a veteran astronaut, is currently the 11th director of Johnson Space Center. She became the first Hispanic woman to go to space when she served on the STS-56 mission. via NASA

Central Cygnus Skyscape #NASA

In cosmic brush strokes of glowing hydrogen gas, this beautiful skyscape unfolds across the plane of our Milky Way Galaxy near the northern end of the Great Rift and the center of the constellation Cygnus the Swan. A 36 panel mosaic of telescopic image data, the scene spans about six degrees. Bright supergiant star Gamma Cygni (Sadr) to the upper left of the image center lies in the foreground of the complex gas and dust clouds and crowded star fields. Left of Gamma Cygni, shaped like two luminous wings divided by a long dark dust lane is IC 1318 whose popular name is understandably the Butterfly Nebula. The more compact, bright nebula at the lower right is NGC 6888, the Crescent Nebula. Some distance estimates for Gamma Cygni place it at around 1,800 light-years while estimates for IC 1318 and NGC 6888 range from 2,000 to 5,000 light-years. via NASA

Space Station View of Mount Etna Erupting #NASA

The Expedition 50 crew aboard the International Space Station had a nighttime view from orbit of Europe’s most active volcano, Mount Etna, erupting on March 19, 2017. Astronaut Thomas Pesquet of ESA captured this image, writing, “Mount Etna, in Sicily. The volcano is currently erupting and the molten ava is visible from space, at night!” via NASA

The Aurora Tree #NASA

Yes, but can your tree do this? Pictured is a visual coincidence between the dark branches of a nearby tree and bright glow of a distant aurora. The beauty of the aurora — combined with how it seemed to mimic a tree right nearby — mesmerized the photographer to such a degree that he momentarily forgot to take pictures. When viewed at the right angle, it seemed that this tree had aurora for leaves! Fortunately, before the aurora morphed into a different overall shape, he came to his senses and capture the awe-inspiring momentary coincidence. Typically triggered by solar explosions, aurora are caused by high energy electrons impacting the Earth’s atmosphere around 150 kilometers up. The unusual Earth-sky collaboration was witnessed earlier this month in Iceland. via NASA
