Rigorous Analysis Confirms NASA’s Artemis II Heat Shield Performance NASA’s Artemis II mission sent four astronauts around the Moon and brought them safely back to Earth, laying a foundation for crewed flights to the Moon’s surface. Additional engineering data analysis of the Orion spacecraft’s heat shield confirmed initial data showing the heat shield performed as expected. In particular, NASA measured whether the thermal protection […]
Chandra Finds Possible Origin of ‘Treble Clef’ WavesA formation of radio waves looks remarkably like a treble clef in this Oct. 14, 2026, image from NASA’s Chandra X-Ray Observatory. Researchers used Chandra to find that the Treble Clef is likely caused by an outburst from a supermassive black hole, followed by a collision of two galaxy clusters. Read more about this discovery.

NASA’s Chandra Breaks Down ‘Treble Clef’s’ Galaxy Cluster CollisionAstronomers have used NASA’s Chandra X-ray Observatory to break down the cause of a remarkable formation of radio waves they have nicknamed the “Treble Clef” because its distinct shape strongly resembles the musical symbol. The researchers discovered the Treble Clef is likely caused by an outburst from a supermassive black hole, followed by a collision […]
NASA’s Space X CRS-35 Launch JellyfishSunlight illuminates the exhaust plumes of a SpaceX Falcon 9 rocket carrying the company’s Dragon spacecraft on Oct. 13, 2026. This visual phenomenon is known as a “jellyfish”; it happens near sunrise or sunset when the exhaust plume from the rocket becomes brightly illuminated, creating a glowing shape resembling a jellyfish. The mission lifted off […]
NASA Develops Batteries to Power Humanity’s Return to MoonIf you’ve ever had your car start sluggishly, or not at all, on a particularly frigid winter morning, you know standard batteries do not like extreme cold. That’s why NASA researchers are working to develop a battery that could function in the brutal cold of the Moon’s South Pole, where nighttime temperatures plunge to minus […]
