WAUKESHA, Wis. — At the beginning of each new orbit around the Sun, Astronomy magazine takes the opportunity to look back at all that’s been accomplished in the preceding year. The annual year in science issue is a reader favorite. But years like 2015 are rare, even for a frontier science like astronomy.

Within just the past 12 months, NASA’s New Horizons mission has revealed long-held secrets from Pluto, and the space agency’s Dawn mission has shown astronomers Ceres, another dwarf planet. But Rosetta also zoomed in on its comet, returning unprecedented observations. And the NuSTAR telescope found a surprising X-ray glow coming from our galactic center. Astronomers also learned that water abounds in the outer solar system, with fresh data indicating that both Enceladus and Ganymede have global oceans.

These finds and many others from 2015 will force textbooks to be rewritten. But you can learn about them already by picking up the January issue of Astronomy, on newsstands December 1.
