• The delta plain of the Mississippi River is disappearing. The lobe-shaped arc of coastal land from the Chandeleur Islands in eastern Louisiana to the Sabine River loses a football field’s worth of land every hour. Put another way, the delta has shrunk by nearly 5,000 square kilometers (2,000 square miles) over the past 80 years. That’s as if most of

  • NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) enters the Lufthansa Technik hangar in Hamburg, Germany for its decadal inspection. Flight, aircraft maintenance, and science personnel from the Armstrong Flight Research Center worked alongside Lufthansa’s 747 specialists to perform a wide range of inspections and maintenance. Water vapor in the Earth’s atmosphere absorbs infrared radiation, preventing a large section of the

  • A dark, snaking line across the lower half of the sun in this Feb. 10, 2015 image from NASA’s Solar Dynamics Observatory (SDO) shows a filament of solar material hovering above the sun’s surface. SDO shows colder material as dark and hotter material as light, so the line is, in fact, an enormous swatch of colder material hovering in the

  • Galaxies can take many shapes and be oriented any way relative to us in the sky. This can make it hard to figure out their actual morphology, as a galaxy can look very different from different viewpoints. A special case is when we are lucky enough to observe a spiral galaxy directly from its edge, providing us with a spectacular

  • On Feb. 5. 1971, the Apollo 14 crew module landed on the moon. The crew members were Captain Alan Bartlett Shepard, Jr. (USN), commander; Major Stuart Allen Roosa (USAF), command module pilot; and Commander Edgar Dean Mitchell (USN), lunar module pilot. In this photo, Shepard stands by the Modular Equipment Transporter (MET). The MET was a cart for carrying around

  • NASA’s Curiosity Mars rover can be seen at the “Pahrump Hills” area of Gale Crater in this view from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter.  Pahrump Hills is an outcrop at the base of Mount Sharp. The region contains sedimentary rocks that scientists believe formed in the presence of water. The location of

  • Ice, wind, cold temperatures and ocean waters combined to created dramatic cloud formations over the Bering Sea in late January, 2015. The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Aqua satellite passed over the region and captured this true-color image on Jan. 23. The frozen tundra of Russia lies in the northwest of the image, and snow-covered Alaska lies in
