CLOSE UP Scientists have found an exoplanet 11 times the mass of Jupiter cuddling up to a young star (similar to one illustrated here). The newfound planet, which orbits its 2-million-year-old star once every nine days, could help scientists understand how large planets form near their stars.
TECTONIC TIMETABLE Plate tectonics will grind to a halt in a few billion years, researchers predict. A computer simulation calculated how heat flows through a planet’s interior, including this snapshot during a period of active plate tectonics.
