When a star like the Sun begins to run out of helium to burn, it will blow off huge clouds of gas and dust. These outbursts can form spectacular structures such as the one seen in the Cat’s Eye nebula. This image of the Cat’s Eye contains both X-rays from Chandra around the center and visible light data from the Hubble Space Telescope, which show the series of bubbles expelled by the star over time. To listen to these data, there is a radar-like scan that moves clockwise emanating from the center point to produce pitch. Light that is further from the center is heard as higher pitches while brighter light is louder. The X-rays are represented by a harsher sound, while the visible light data sound smoother. The circular rings create a constant hum, interrupted by a few sounds from spokes in the data. The rising and falling pitches that can be heard are due to the radar scan passing across the shells and jets in the nebula.

Messier 51 (M51) is perhaps better known by its nickname of the Whirlpool Galaxy because its face-on orientation to Earth reveals its wound-up spiral arms. This gives telescopes here a view of another spiral galaxy similar to our Milky Way, whose structure we cannot observe directly from our position within it. As with the Cat’s Eye, the sonification begins at the top and moves radially around the image in a clockwise direction. The radius is mapped to notes of a melodic minor scale. Each wavelength of light in the image obtained from NASA telescopes in space (infrared, optical, ultraviolet, and X-ray) is assigned to a different frequency range. The sequence begins with sounds from all four types of light, but then separately moves through the data from Spitzer, Hubble, GALEX, and Chandra. At wavelengths in which the spiral arms are prominent, the pitches creep upwards as the spiral reaches farther from the core. A constant low hum associated with the bright core can be heard, punctuated by short sounds from compact sources of light within the galaxy.

A cross-section of a 3D simulation replicating a scenario for the impact that formed the Moon, showing a roughly Mars-mass impactor grazing an Earth-like target at a 45-degree angle. The simulation uses over 100 million particles, colored by their internal energy, related to their temperature.

This is one of more than 300 simulations that scientists at Durham University in the United Kingdom, alongside researchers at NASA’s Ames Research Center in California’s Silicon Valley, ran to develop a way to predict how much atmosphere is lost from a wide range of collisions between rocky objects, presented in a new study.

We propose a novel spacesuit intelligent architecture for extravehicular activity (EVA) operations on Mars and other planetary environments that increases human performance by an order of magnitude on several quantifiable fronts for exploration missions. The proposed SmartSuit spacesuit, while gas-pressurized, also incorporates soft-robotics technology that allows astronauts to be highly mobile and better interact with their surroundings. The spacesuit also incorporates a soft and stretchable self-healing skin (or membrane) located in the outer layer that not only protects the astronaut but also collects data through integrated, transparent sensors embedded in the membrane. These sensors are capable of visually displaying environmental and membrane structural information, providing visual feedback to the wearer about the surroundings.

The SpaceX team attempted a high-altitude flight test of Starship serial number 11 (SN11) – our fourth high-altitude flight test of a Starship prototype from Starbase in Texas. Similar to previous high-altitude flight tests of Starship, SN11 was powered through ascent by three Raptor engines, each shutting down in sequence prior to the vehicle reaching apogee – approximately 10 km in altitude. SN11 performed a propellant transition to the internal header tanks, which hold landing propellant, before reorienting itself for reentry and a controlled aerodynamic descent.

A controlled aerodynamic descent with body flaps and vertical landing capability, combined with in-space refilling, are critical to landing Starship at destinations across the solar system where prepared surfaces or runways do not exist, and returning to Earth. This capability will enable a fully reusable transportation system designed to carry both crew and cargo on long-duration, interplanetary flights and help humanity return to the Moon, and travel to Mars and beyond.

Video shows engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, completing the welds to form the launch vehicle stage adapter (LVSA) for NASA’s Space Launch System (SLS) rocket. The launch vehicle stage adapter in this video will fly on Artemis II, the first crewed mission of NASA’s Artemis program. Upon stacking the upper and lower cones, technicians use advanced robotic tooling and an innovative process called friction stir welding, to join the cones of the LVSA to form one structure.

The next step in the manufacturing process is the installation of the pneumatically actuated frangible joint which sits atop the LVSA and helps separate the core stage and LVSA from the Interim Cryogenic Propulsion Stage (ICPS) during flight. After the core stage launches the rocket, the ICPS provides the power to send the Orion spacecraft and its crew to the Moon.
