NASA Captures August Total Solar Eclipse from Ground, Air and Space

A total solar eclipse swept across Greenland, Iceland, and Spain on August 12, briefly plunging those regions into darkness. As the Moon fully blocked the Sun, observers in the path of totality were able to see the solar corona, the Sun's faint outer atmosphere, which is normally hidden by daylight. NASA deployed researchers and photographers across multiple vantage points to document the event. The agency captured imagery and data from ground level, airborne platforms, and spacecraft to study the phenomenon. Clear skies were required for ground-based observers to witness totality, making favorable weather a key factor in the experience.

NASA Updates CEA Code, a Core Tool for Propulsion and Aerospace Analysis

NASA is modernizing its Chemical Equilibrium with Applications (CEA) code, a foundational software tool widely used for propulsion system analysis. The code supports calculations involving equilibrium chemistry, rocket performance, shock waves, and detonations. It is utilized across NASA programs as well as by the broader aerospace community. The update effort is being led by Mark K. Leader at NASA's Glenn Research Center and is overseen by the NASA Engineering and Safety Center (NESC).

Webb Telescope Captures Rare Cometary Globule in Carina Nebula

NASA's James Webb Space Telescope photographed a structure known as the 'Treasure Chest' within the Carina Nebula on August 6, 2026. The image, captured in infrared, shows a portion of the nebula that also contains the well-known Cosmic Cliffs formation. The Treasure Chest is classified as a cometary globule, a type of isolated cloud composed of gas and dust with a dense core. Carina Nebula is an active star-forming region, making it a key target for astronomers studying stellar formation. Webb's infrared capabilities allow it to peer through cosmic dust and reveal structures that are otherwise difficult to observe.
