Geomedia: Performance: Bella Gaia is a show in orbit and Earth is the star

On the screen, images of the far reaches of the cosmos — galaxies, stellar nebulae and supernovae — loom high over a stage. The words, “The Living Universe,” appear and the view zooms in: first on our galaxy, then on our solar system and, finally, on Earth. Bella Gaia, a live performance piece featuring dance and music set in front of a large projection-screen displaying images of Earth from space, begins.

Down to Earth With: Solar physicist Thomas Berger

Growing up in California during the Space Race, Thomas Berger was fascinated with aeronautics and aviation, so when he arrived at the University of California at Berkeley, physics seemed like the natural choice. After graduating with a degree in engineering physics, Berger took a job with Lockheed Aircraft in Burbank. But he soon decided it was not for him and returned to graduate school at Stanford, where he discovered a new passion: solar physics.

Benchmarks: April 22, 1995: GLOBE is launched

Studying the global environment requires collecting numerous detailed observations. And although it may seem today like we’re awash in such data, relevant observations — collected at the right time and place — are often unavailable. For example, scientists studying precipitation must rely on just a handful of sampling stations: All of the world’s raingages gathered together would only cover an area the size of two basketball courts.

Lunar atmosphere more active than we thought

LADEE — pronounced “laddie” and short for Lunar Atmosphere and Dust Environment Explorer — was among the shortest-lived of NASA’s successful satellites. Launched on Sept. 7, 2013, it crashed onto the moon’s surface, as intended, on April 17, 2014, after six months orbiting the moon. Data collected by LADEE have already greatly expanded our understanding of the atmosphere of the moon and other bodies in the solar system; the spacecraft also made a number of unexpected discoveries, some of which were presented at the fall meeting of the American Geophysical Union (AGU) in San Francisco last December.

Benchmarks: February 1962 and 1984: John Glenn and Bruce McCandless make space flight history

On the morning of Feb. 20, 1962, John H. Glenn sat inside the Mercury Friendship 7 space capsule, perched atop a rocket that had initially been designed to deliver nuclear warheads to the far ends of the world. That rocket would propel Glenn into space, and into the history books, as the first American to orbit Earth.

Map shows where lightning zaps most

Lightning strikes far more often over land than sea and is more concentrated closer to the equator — both testaments to the greater atmospheric instability over those parts of the planet.

Nanoflares power the sun's superheated corona

The sun’s outer atmosphere, or corona, reaches temperatures of more than 1 million degrees Celsius, hundreds of times hotter than its visible surface. The reason for this has puzzled scientists, who so far have only been able to theorize explanations.

New satellite maps carbon dioxide sources and sinks in high definition

A recently launched satellite is now measuring atmospheric carbon dioxide with greater precision than ever before. Launched on July 2, the Orbiting Carbon Observatory-2 (OCO-2) is already mapping levels of carbon dioxide, the presence of which in the air constantly varies by region and over time. It has also validated a new technique of analysis that was not even contemplated when the mission was planned, according to scientists who discussed the mission at a press conference during the annual meeting of the American Geophysical Union (AGU) in San Francisco.

Red Planet Roundup: November 2014

As Curiosity and Opportunity rove around Mars, the Mars Reconnaissance Orbiter (MRO), Mars Express and Mars Odyssey orbit above, and scientists on Earth study the Red Planet from afar, new findings are announced almost weekly. Here are a few of the latest updates.
