1. NASA’s Gravity and Climate Experiment (GRACE) is an audacious mission to track the impact of climate change on the planet’s vast tracts of freshwater, saltwater, and ice. GRACE’s pair of satellites responds to the gravitational pull of these massive stores, effectively “weighing” Earth’s shifting water resources month by month. The satellites can detect where water is accumulating and drying up on a grand scale—data that were unavailable before. GRACE’s unprecedented view of our water planet could prove critical in the effort to anticipate and manage the consequences of climate change for people worldwide.

  2. In an underwater cave in the Yucatán, divers discovered a near-complete human skeleton dating to the first wave of migration to North America. DNA evidence from these remains is helping scientists solve a long-standing mystery about whether contemporary Native Americans are descended from these first American arrivals.

  3. In the Arctic, where air temperatures are rising at about twice the global rate, scientists are seeing major shifts in plant life. Trees and shrubs are expanding by pushing northward, while the low-to-the-ground tundra plants to their north are shrinking in range. In this visualization, watch these changes and the influence they are forecasted to have on the climate system.

  4. As seismic waves from earthquakes pass through the planet, their patterns can reveal hidden dynamics—hotspots, deep-diving rock, melting mantle—in Earth’s interior. An array of seismometers that’s being installed across the United States is now allowing geophysicists to plot revelatory views of the Earth engine deep beneath our feet.

  5. Jupiter is a planet of extremes—it’s the biggest in our solar system, it spins the fastest, it hosts the most moons, and it has the most turbulent atmosphere. But one of its most recognizable features, an enormous storm known as the Great Red Spot, is coming up short. The storm has been getting smaller for decades, but recent images show that it’s now shrinking even faster.
