Hubble sees a maelstrom of glowing gas and dark dust within one of the Milky Way’s satellite galaxies, the Large Magellanic Cloud. http://www.nasa.gov/sites/default/files/thumbnails/image/potw1636a.jpg

As Tropical Storm Hermine charged up the East Coast Sept. 2, the hangar at NASA Langley was able to carefully sandwich in more than a dozen Air Force fighters and offer them protection from the wind. The hangar provides 85,200 square feet (7,915 square meters) of open space and large door dimensions that allow for entry of big aircraft. http://www.nasa.gov/sites/default/files/thumbnails/image/lrc-2016-h1_p_stormprep-0902031.jpg

This image shows a portion of Lethe Vallis, an outflow channel that also transported lava. This is one of only a few places on Mars where these pristine-appearing landforms have been identified. The channel formed by catastrophic floods, during which it produced the prominent crater-cored, teardrop-shaped island in the middle. http://www.nasa.gov/sites/default/files/thumbnails/image/esp_045833_1845.jpg

This illustration shows a glowing stream of material from a star, disrupted as it was being devoured by a supermassive black hole. The feeding black hole is surrounded by a ring of dust. This dust was previously illuminated by flares of high-energy radiation from the feeding black hole, and is now shown re-radiating some of that energy. http://www.nasa.gov/sites/default/files/thumbnails/image/pia20027_updated.jpg

NASA's IceBridge, an airborne survey of polar ice, flew over the Helheim/Kangerdlugssuaq region of Greenland on Sept. 11, 2016. This photograph from the flight captures Greenland's Steenstrup Glacier, with the midmorning sun glinting off of the Denmark Strait in the background. http://www.nasa.gov/sites/default/files/thumbnails/image/steenstrup.jpeg

Pan may be small as satellites go, but like many of Saturn's ring moons, it has a has a very visible effect on the rings. http://www.nasa.gov/sites/default/files/thumbnails/image/pia20499_1041.jpg

The southern tip of Italy is visible in this image taken by the Expedition 49 crew aboard the International Space Station on Sept. 17, 2016. The brightly lit city of Naples can be seen in the bottom section of the image. A Russian Soyuz spacecraft can be seen in the foreground. http://www.nasa.gov/sites/default/files/thumbnails/image/29185512413_b2e78e5bc2_o.jpg

NASA astronaut Kate Rubins checks a sample for air bubbles prior to loading it in the biomolecule sequencer. When Rubins’ expedition began, zero base pairs of DNA had been sequenced in space. Within just a few weeks, she and the Biomolecule Sequencer team had sequenced their one billionth base of DNA aboard the orbiting laboratory. http://www.nasa.gov/sites/default/files/thumbnails/image/iss048e069879.jpg

A group of U.S. Navy divers, Air Force pararescuemen and Coast Guard rescue swimmers practice Orion underway recovery techniques in the Neutral Buoyancy Laboratory at NASA’s Johnson Space Center to prepare for the first test flight of an uncrewed Orion spacecraft with the agency’s Space Launch System rocket during Exploration Mission (EM-1). http://www.nasa.gov/sites/default/files/thumbnails/image/29759265711_c40946f688_o.jpg

This star is ending its life by casting off its outer layers of gas, which formed a cocoon around the star's remaining core. http://www.nasa.gov/sites/default/files/thumbnails/image/heic0703a.jpg

New NASA-funded research suggests that Mercury is contracting even today, joining Earth as a tectonically active planet. Images obtained by NASA’s MESSENGER spacecraft reveal previously undetected small fault scarps— cliff-like landforms that resemble stair steps. http://www.nasa.gov/sites/default/files/thumbnails/image/press_photo_4.jpg

Orbiting above eastern North America, a crew member on the International Space Station photographed a dense pattern of eddies in the Gulf of St. Lawrence. Caught briefly in the Sun’s “glint point,” reflections off the water surface show an interlinked mass of swirls and eddies in the shallow water north of Prince Edward Island. http://www.nasa.gov/sites/default/files/thumbnails/image/iss048e071829_lrg.jpg

This image of galaxy cluster Abell 2744, also called Pandora's Cluster, was taken by the Spitzer Space Telescope. http://www.nasa.gov/sites/default/files/thumbnails/image/pia20920.jpg

In this photograph taken on Sept. 1, 2016, the James Webb Space Telescope Pathfinder structure has been configured for the Thermal Pathfinder Test at NASA Johnson Space Center's giant thermal vacuum chamber, called Chamber A. The Pathfinder is a test version of the structure that supports the telescope. http://www.nasa.gov/sites/default/files/thumbnails/image/29677447760_35cb318fbb_o.jpg

The Bigelow Expandable Activity Module (BEAM) is seen attached to the Tranquility module of the International Space Station. BEAM is an is an experimental expandable habitat. Expandable habitats, occasionally described as inflatable habitats, greatly decrease the amount of transport volume for future space missions. http://www.nasa.gov/sites/default/files/thumbnails/image/29894260842_1d70c6d562_o.jpg

On September 29, 2016, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this false-color image (MODIS bands 7-2-1) showing volcanic activity in the South Sandwich Islands. Located in the South Atlantic Ocean, the uninhabited South Sandwich Islands include several active stratovolcanoes. http://www.nasa.gov/sites/default/files/thumbnails/image/southsandwich_amo_2016273_lrg.jpg

This 360-degree panorama was acquired by the Mast Camera (Mastcam) on NASA's Curiosity Mars rover . http://www.nasa.gov/sites/default/files/thumbnails/image/pia20840.jpg

On October 4, 2016, Hurricane Matthew made landfall on southwestern Haiti as a category-4 storm—the strongest storm to hit the Caribbean nation in more than 50 years. Just hours after landfall, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this natural-color image. http://www.nasa.gov/sites/default/files/thumbnails/image/matthew_tmo_2016278_lrg.jpg

The International Space Station has tracked Hurricane Matthew all week, providing images and video from low Earth orbit as the storm hit the Caribbean Sea and made its way towards Florida. In this photograph taken by Expedition 49 Flight Engineer Kate Rubins on Oct. 4, 2016, at 21:05 GMT, the hurricane's clouds extend across the frame. http://www.nasa.gov/sites/default/files/thumbnails/image/iss049e028833.jpg

Astronauts on the International Space Station captured a series of incredible star trail images on Oct. 3, 2016, as they orbited at 17,500 miles per hour. The station orbits the Earth every 90 minutes, and astronauts aboard see an average of 16 sunrises and sunsets every 24 hours. http://www.nasa.gov/sites/default/files/thumbnails/image/29529061813_6797c55422_o.jpg
