NASA's TESS mission has given astronomers something to marvel at: two newly confirmed planets orbiting a Sun-like star called TOI-seven ninety one. These gas giants are roughly the size of Jupiter but carry only a tiny fraction of its mass, making them the lowest-density, or quote puffiest, planets ever recorded. It raises fascinating questions about how planetary systems form and what extremes nature will reach.
Shifting from the cosmos to your camera bag, Nikon has made a wireless-free version of one of its cameras available to the public for the first time. Stripped of all radio transmission capability, the camera is designed for environments where wireless signals are simply not permitted, think secure government facilities or certain research settings. It's a niche product, but it tells a broader story about how seriously some institutions take electromagnetic security.
And for developers working with AI, a new open-source tool called Promptctl is pitching itself as essentially Git for your prompts. The idea is to bring version control discipline to the often chaotic process of iterating on language model instructions, letting teams track changes, roll back, and collaborate more systematically. Whether it catches on depends on how seriously the industry treats prompt engineering as a real engineering practice.
