The greening Arctic: Using almost 30 years of data from our satellites, scientists track changes in vegetation in Alaska and Canada. Of the more than 4 million square miles, 30% had increases in vegetation (greening). Temperatures are warming faster in the Arctic than elsewhere, which has led to longer seasons for plans to grow and changes in the soil.

Our planet-hunting Transiting Exoplanet Survey Satellite (TESS) has discovered 66 worlds, observed exploding stars, and watched a black hole shred a star like our Sun. And that's just part of the story. Now in its extended NASA Exoplanets mission, TESS is surveying the universe better and faster than ever before.
