1. 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.

  2. 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.

  3. 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.

  4. The ocean waters surrounding the South Pacific’s Solomon Islands are home to diverse communities of fish, corals, and other animals. Many of these marine species can absorb light and emit it as another color, a process called biofluorescence. American Museum of Natural History scientists dove deep to investigate creatures that illuminate the ocean, and to better understand how and why they transform light.

    In "The Expedition Begins," see underwater creatures in colors that are usually invisible to the human eye.

    Explore21 is a new Museum initiative to support scientific exploration that integrates fieldwork with emerging technologies, unlocking secrets of the natural world.

American Museum of Natural History scientists dove deep to investigate creatures that illuminate the ocean, and to better understand how and why they transform light.

    In "The Fish," Museum scientists collect and analyze hundreds of species to find out how many fish groups are biofluorescent and how they might use light to communicate.
