Ceres’ Bright Spot Has a Companion

Ceres-200

Dwarf planet Ceres continues to puzzle scientists as NASA’s Dawn spacecraft gets closer to being captured into orbit around the object. The latest images from Dawn, taken nearly 29,000 miles (46,000 kilometers) from Ceres, reveal that a bright spot that stands out in previous images lies close to yet another bright area. “Ceres’ bright spot…

The Furious Winds From Black Holes

Black-Hole-150

NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) and ESA’s (European Space Agency) XMM-Newton telescope are showing that fierce winds from a supermassive black hole blow outward in all directions — a phenomenon that had been suspected, but difficult to prove until now. This discovery has given astronomers their first opportunity to measure the strength of these…

Science Documentaries

I enjoy watching documentaries on a wide variety of topics. This visual medium is more concise than reading books but imparts a lot of information through two senses simultaneously – sight and hearing. Books, at best, can provide only static images whereas documentaries provide sweeping vistas, views from a distance as well as close-up, words…

Titan-150

During 10 years of discovery, NASA’s Cassini spacecraft has pulled back the smoggy veil that obscures the surface of Titan, Saturn’s largest moon. Cassini’s radar instrument has mapped almost half of the giant moon’s surface; revealed vast, desert-like expanses of sand dunes; and plumbed the depths of expansive hydrocarbon seas. What could make that scientific…

Droughts in the U.S. Southwest and Central Plains during the last half of this century could be drier and longer than drought conditions seen in those regions in the last 1,000 years, according to a new NASA study. The study, published Thursday in the journal Science Advances, is based on projections from several climate models,…

A Comet Is Like Deep Fried Ice Cream

Bright-Comet-150

Astronomers tinkering with ice and organics in the lab may have discovered why comets are encased in a hard, outer crust. Using an icebox-like instrument nicknamed Himalaya, the researchers show that fluffy ice on the surface of a comet would crystalize and harden as the comet heads toward the sun and warms up. As the…
