NASA’s Nancy Grace Roman Space Telescope is poised to make a major leap in the hunt for worlds outside our solar system, known as exoplanets. Scientists expect the mission to reveal around 100,000 worlds — a staggering leap compared to the nearly 6,300 found so far thanks to NASA missions working in tandem with other […]

With peak wildfire season approaching, scientists with NASA’s FireSense project have created low-cost thermal sensors to install on fire bulldozers that will alert firefighters when heat from a nearby fire reaches a dangerous level. The sensors also provide researchers with important data on what happens beneath the canopy during a fire.
