Yellowstone National Park lies above a stationary hotspot deep in Earth's mantle. See how previous volcanic eruptions of the hotspot have left a trail of calderas that ends, at the moment, with Yellowstone.
Vietnam harbors an astonishing range of habitats, from rain forests and dry forests to mangroves and coral reefs. It's also home to an unusually rich array of plants and animals. Find out why.
In 1998, astrophysicists discovered a baffling phenomenon: the Universe is expanding at an ever-faster rate. Either an enigmatic force called dark energy is to blameor a reworking of gravitational theory is in order. In this new Science Bulletins video, watch a Fermilab team assemble the Dark Energy Camera, a device that could finally solve this space-stretching mystery.
Science Bulletins is a production of the National Center for Science Literacy, Education, and Technology (NCSLET), part of the Department of Education at the American Museum of Natural History. Each Bulletin is produced by AMNHs curatorial and scientific staff and a team of video producers, designers, writers, and educators using state-of-the-art technologies such as high-definition video and 3-D computer graphics to present the latest research.
Millions of gallons of water flow through New York City’s water system each day. Where does it all come from? And where does it all go? Take an interactive journey to find out.
Focus on the best books about astronomy, astrophysics, light, telescopes, digital imaging, and the 3-D universe with this list of recommended titles, suitable for older students and adults.
Considered the world's most intriguing genius, Einstein has inspired hundreds of writings. Here's a short list of some of the most enlightening looks at his life and ideas, including some he penned.
Earth's ice sheets are rapidly losing volume as humans have warmed the Arctic by over 2 degrees Celsius in the past 50 years. Could Greenland really unfreeze? And what might happen if it does?
Mount St. Elias, the third-highest peak in North America, is among the fastest growing ranges in the world, rising 3 to 4 millimeters a year. Find out what this natural laboratory is helping scientists learn about mountain building.
If technology, cost, and terrain permitted, scientists seeking key data on stars in our galaxy would have loved to construct a behemoth 330 m wide telescope atop Mount Wilson, just northeast of Los Angeles. Instead, they arranged six smaller telescopes over an identical area, synchronizing the light to achieve an equally superlative resolution. Called the Center for High Angular Resolution Astronomy (CHARA), the array uses the technique of interferometry to spot details the size of a nickel seen from 16,000 km away. Hear from project astronomers why the labyrinthine engineering required for CHARA's renowned precision is a small sacrifice for the valuable data it gleans on the properties and life cycles of stars.
Launched on December 14, 2009, the WISE space telescope is helping scientists create a Digital Universe 3-D Atlas. Take a look at WISE and the data it is capturing.
