Its original name, "Constitution", commemorated the United States Bicentennial in 1976, but a campaign led by dedicated fans of the television series "Star Trek" led President Gerald R. Ford to request that NASA change the name to "Enterprise". The shuttle flew eight captive flights on the back of a 747 to evaluate its systems in a flight environment, and five free flights tested its ability to approach a runway and land safely. With the conclusion of the space shuttle program, Enterprise and the rest of the shuttle fleet will be permanently displayed around the country.

| | | | | | | | | | | | | | | | | | | | | | | | | For more than four decades, Dame Daphne Sheldrick has devoted her life to rescuing orphaned animals in East Africa and preparing them for return to the wild on her elephant orphanage near Nairobi, Kenya. An extraordinary conservationist, Dame Daphne is the first person to successfully hand-rear newborn elephants, thanks in large part to the formula she perfected to mimic a mother elephant's milk. Her work is featured in the Museum's current IMAX feature, Born to Be Wild, playing now through June 30. On May 8, 2012, Dame Daphne spoke at the Museum and discussed her book Love, Life, and Elephants: An African Love Story. | Views: 871 18 ratings | | Time: 56:51 | More in Science & Technology |
| | | | | | | | | | | | | | | | | | | | | | | | | Months before the opening of Creatures of Light on March 31, a team of preparators at the American Museum of Natural History began developing custom models of glowing organisms that light up the exhibition. Director of Exhibition Design Michael Meister and other members of the Exhibition Department share how they conduct visual research for these unique models, work with curators to make them scientifically accurate, and meet the various lighting challenges of creating an exhibition about bioluminescence. Creatures of Light (March 31, 2012 - January 6, 2013) introduces visitors to the astonishing variety of bioluminescent organisms and explores the various ways they glow, the functions of bioluminescence, and how scientists study this remarkable characteristic. The exhibition unfolds through a series of immersive environments, beginning in a forest of bioluminescent mushrooms and taking visitors through a meadow filled with fireflies, a bioluminescent bay in Puerto Rico, coral reefs, and the deep sea to highlight the ways in which different animals use bioluminescence to attract mates and prey, and to threaten predators. Along the way, see live flashlight fish and special equipment, including a scale model of a deep-sea submersible.

| | | | | | | | | | | | | | | | | | | | | | | | | On Tuesday, March 20, 2012, over 5000 people tuned in to the live stream of the 2012 Isaac Asimov Memorial Debate from the LeFrak Theater at the American Museum of Natural History. Hosted by Hayden Planetarium Director Neil deGrasse Tyson, this year's debate pitted some of the experimentalists who claimed to have discovered faster-than-light neutrinos against their strongest critics, as well as other teams who are racing to test Albert Einstein's Theory of Relativity with unprecedented precision.

| | | | | | | | | | | | | | | | | | | | | | | | | When researchers in Brazil studied the early larval stages of the butterfly Aricoris propitia, they discovered that the larvae had solicitous caretakers—fire ants. Fire ants are a notorious invasive species and are frequently seen as pests, but A. propitia butterflies actively seek them out when choosing a location for egg-laying. The ants attend the larvae, transporting them to shelter during the day and carrying them out again at night to feed on the host plant. The ants appear to benefit from the larvae's "ant-organs," which dispense a type of nectar and a substance that produces a stimulating effect. Fire ants are extremely adaptable, especially in distressed environments, and as deforestation and development reduce the butterflies' habitats in Brazil's Amazon and Cerrado regions, this highly successful partnership may inform scientific understanding of the future distribution and success of the two species.

| | | | | | | | | | | | | | | | | | | | | | | | | 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 16000 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. | Views: 132 15 ratings | | Time: 06:31 | More in Science & Technology |
| | | | | | | | | | | | | | | | | | | | | | | | | Gamma-ray bursts—flashes of intense radiation in space that are often just seconds long—were accidentally discovered in the 1960's by satellites built to monitor nuclear bomb explosions. They've been one of the leading astrophysical mysteries ever since. This Astro Bulletin introduces you to the scientists and instruments working to unravel the origins of gamma-ray bursts. It highlights Swift, NASA's burst-detecting satellite, and PAIRITEL, one of a fleet of ground-based telescopes that point toward a gamma-ray burst in response to Swift's alert to capture the afterglow before it fades. Astrophysicists at Penn State and other institutions are analyzing these afterglows to understand what causes the most powerful explosions known. | Views: 172 21 ratings | | Time: 06:00 | More in Science & Technology |
| | | | | | | | | | | | | | | | | | | | | | | | | Several recent studies have questioned whether exposure to common pesticides might be impairing bee performance and contributing to the observed population declines. Neonicotinoids are a family of pesticides chemically related to nicotine, and are widely used in both large-scale agriculture as well as in home gardening products. This type of pesticide circulates through flowering plants and collects in nectar and pollen. Recent studies conducted by several research groups have shown that even low doses of neonicotinoid pesticides can impair bees' navigation abilities and reduce the growth of bee colonies. Insects, particularly bees, are the dominant pollinators in temperate regions worldwide. Declines of honey, bumble, and solitary bees may lead to serious repercussions, not only for crop plant production but for the reproductive success of wild flowering plants, as well.

| | | | | | | | | | | | | | | | | | | | | | | | | Brown dwarfs are cosmic objects that are intermediate between stars and planets. Scientists have spent more than a decade seeking confirmation of the coolest, faintest type of brown dwarfs—Y-dwarfs—which had been predicted but never seen. Recently, the powerful infrared vision of NASA's Wide-Field Infrared Survey Explorer, or WISE, has captured these phantoms during its sweeping survey of the night sky. | Views: 620 40 ratings | | Time: 01:36 | More in Science & Technology |
