NASA — Did comet Ison survive its trip around the sun? After several days of continued observations, scientists continue to work to determine and to understand the fate of Comet ISON: There’s no doubt that the comet shrank in size considerably as it rounded the sun and there’s no doubt that something made it out […]

Galaxy Growth Like Watching Paint Dry
NASA — Watching a tree grow might be more frustrating than waiting for a pot to boil, but luckily for biologists, there are tree rings. Beginning at a tree trunk’s dense core and moving out to the soft bark, the passage of time is marked by concentric rings, revealing chapters of the tree’s history. Galaxies […]
Russian Meteor Plume
Atmospheric physicist Nick Gorkavyi missed witnessing an event of the century last winter when a meteor exploded over his hometown of Chelyabinsk, Russia. From Greenbelt, Md., however, NASA’s Gorkavyi and colleagues witnessed the atmospheric aftermath. The explosion created a never-before-seen belt of “meteor dust” that circulated through the stratosphere for at least three months. Shortly […]
Earth From 900 Million Miles
NASA’s Cassini spacecraft captured the color images of Earth and the moon from its perch in the Saturn system nearly 900 million miles (1.5 billion kilometers) away. MESSENGER, the first probe to orbit Mercury, took a black-and-white image from a distance of 61 million miles (98 million kilometers) as part of a campaign to search […]
Solar Radiation Storms
Solar radiation storms continue. It takes about two days for the effects to reach Earth. A solar flare is a sudden brightening observed over the Sun’s surface or the solar limb, which is interpreted as a large energy release of up to 6 × 1025 joules of energy (about a sixth of the total energy […]

Human Asteroid Initiative
NASA’s FY2014 budget proposal includes a plan to robotically capture a small near-Earth asteroid and redirect it safely to a stable orbit in the Earth-moon system where astronauts can visit and explore it. Performing these elements for the proposed asteroid initiative integrates the best of NASA’s science, technology and human exploration capabilities and draws on […]
When Does an Asteroid Become a Meteor?
EARTH — NASA has been watching an asteroid, Asteroid 2012 DA14, fly near Earth; however, they missed another asteroid that became a meteor in Russia. An asteroid when it enters the Earth’s atmosphere. Usually, they burn up upon entry. Not this time. A Russian health official estimated 1,000 people were injured when a 10 ton […]
