The GBM consists of 12 sodium iodides (NaI) detectors (8 keV–1 MeV) and two bismuth germanate (BGO) detectors (20 keV –40 MeV)²⁵, which has three different data types: continuous time (CTIME), continuous…

Satellites are increasingly a global-communications lifeline, allowing people in remote areas, even…

In the next few months, from its perch atop a mountain in Chile, the Vera C. Rubin Observatory will begin surveying the cosmos with the largest camera ever built. Every three nights, it will produce a map of the entire southern sky filled with…
