An artist’s concept of SpaceX’s Starship Human Landing System (HLS) on the Moon. NASA is working with SpaceX to develop the Starship HLS to carry astronauts from lunar orbit to the Moon’s surface and back for Artemis III and Artemis IV. Starship HLS is roughly 50 meters tall, or about the length of an Olympic swimming pool.

An image from a 3D simulation showing the evolution of turbulent flows in the upper layers of the Sun. The more saturated and bright reds represent the most vigorous upward or downward twisting motions. Clear areas represent areas where there is only relatively slow up-flows, with very little twisting.

NASA’s Hubble Finds Sizzling Details About Young Star FU Orionis

NASA’s Hubble Finds Sizzling Details About Young Star FU Orionis

The guitar shape in the “Guitar Nebula” comes from bubbles blown by particles ejected from the pulsar through a steady wind as it moves through space. Images from Chandra taken in 2000, 2006, 2012 and 2021 have been combined with a single image in optical light from Palomar. X-rays from Chandra show a filament of energetic matter and antimatter particles, about two light-years long, blasting away from the pulsar (seen as the bright white dot). The movie shows how this filament has changed over two decades. An inset shows a closeup of the “guitar head” from NASA’s Hubble Space Telescope also changing over time from 1994-2021.

The words “SUSAN Electrofan” and “PAX 180” are printed on a graphic along with fuselage, with a large NASA insignia in the center of the plane. The rear of the aircraft model, along with the wings and tail, are taken apart to display the inner components that make up its electrified propulsion system.
