Sonification of RS Puppis Star
NASA’s sonification of RS Puppis, a cepheid variable star located 6,500 light-years from Earth, lets you hear what one of the brightest and biggest stars in the Mihttps://www.techeblog.com/sonification-of-rs-puppis-star/lky Way galaxy could sound like. It’s 200 times larger than our Sun and draped with dust reflecting starlight, rhythmically brightening and dimming over a six-week cycle.

SMARTS 1.5-Meter Telescope Star System Kilonova
Astronomers at NOIRLab used the SMARTS 1.5-meter telescope at the Cerro Tololo Inter-American Observatory (CTIO) to detect a star system that one day will form a kilonova. The difference between a supernova and kilonova is the fact that the former occurs when a star with 8 solar masses collapses into themselves, while the former happens when 2 neutron stars in a binary system collide.

NASA Full-Scale Rotating Detonation Rocket Engine RDRE
It’s official, NASA has successfully tested the first full-scale rotating detonation rocket engine (RDRE), an advanced design that could be used for future deep space missions. Unlike traditional rocket engines that generate thrust using a supersonic combustion phenomenon known as a detonation, the RDRE design generates more power while using less fuel by incorporating a NASA-developed copper-alloy GRCop-42 with the powder bed fusion additive manufacturing process. This enables the engine to operate under extreme conditions for longer durations without overheating.
