An international team of scientists led by the University of Arizona used the latest technology in remote sensing to measure plant biodiversity from the Amazon basin to the Andes Mountains in Peru to better understand how tropical forests will respond to climate change. The researchers used Arizona State University’s Global Airborne Observatory, or GAO, to

Images of the four candidate sample collection sites on asteroid Bennu: Nightingale, Kingfisher, Osprey and Sandpiper. One of these four sites will ultimately be the location on which NASA’s OSIRIS-REx spacecraft will touch down to collect a sample.

This illustration shows the white dwarf WDJ0914+1914 and its Neptune-like exoplanet. Since the icy giant orbits the hot white dwarf at close range, the extreme ultraviolet radiation from the star strips away the planet’s atmosphere. While most of this stripped gas escapes, some of it swirls into a disc, itself accreting onto the white dwarf.

In complex physical systems, the interaction of internal elements is unavoidable, rendering entropy calculation a computationally demanding, and often impractical, task. The tendency of a properly folded protein to unravel, for

Indian artists, once erased from history after immortalizing the wonders of the natural world in paint, are finally getting their due. A new exhibition at the Wallace Collection in London showcases 109 paintings of people, plants and animals commissioned by East India Company officials between the 1770s and 1840s. Titled “Forgotten Masters: Indian Painting for

And while the dynasty’s regalia was glittery and their palaces splendid, the royals themselves were markedly less
