1. Tiny, faraway Pluto was first spied in 1930. This icy world is one of thousands of rocky bodies that make up the Kuiper Belt, a ring that circles our solar system beyond Neptune. Until recently, the most powerful telescopes on Earth and in space could only capture blurry impressions of Pluto and its moons. But in 2015, New Horizons became the first spacecraft to visit the Pluto system, returning detailed images and data that will bring our distant neighbor’s surface, atmosphere, and internal composition into focus for the first time.

  2. Some carnivores eat only meat, while others are more omnivorous. To understand how and when these differences in carnivore feeding may have evolved, Museum paleontologists captured X-ray scans of skulls from living and extinct species. They reconstructed the skulls as virtual models and designed feeding simulations, to test the relationship between skull biomechanics and diet, shedding light on the evolution of feeding specializations and their distribution in the carnivore family tree.

  3. Cassiopeia A is the gas cloud left behind after a star exploded, first glimpsed on Earth about 325 years ago. Its youth and proximity to us make it one of the best-studied supernova remnants in our galaxy. Recent observations have made it possible for scientists to create the first map of the star’s interior in 3D. By reconstructing the explosion and its aftermath, astronomers will better understand the death throes of massive stars.

  4. Chandra, the biggest X-ray space telescope to date, detects high-energy emissions from very hot regions of the universe. Since launching in 1999, Chandra has generated hundreds of thousands of images. But X-rays reveal only part of the picture. Researchers are combining Chandra data with other wavelengths to create images that reveal the different types of energy emitted by objects in space.

  5. Guinea worm, a painful parasite that once affected millions of people each year, may soon be relegated to the past. Thanks to improved health education and community efforts, only 148 cases were reported in 2013. In remote areas of South Sudan where guinea worm still prevails, health workers and epidemiologists track the parasite in an effort to eliminate the disease permanently.
