It may be two inches long, lemon yellow, and the slowest-moving fish in the sea, but it’s also one of the deadliest predators the ocean has ever seen.
With proper coaxing, molecules in microgravity can assemble themselves into forms with surprising properties. Ths new NASA ScienceCast video explores the possibilities
Get the facts about comet ISON. The manager of NASA’s Near-Earth Object Program Office shares the low-down on the stellar object’s holiday travel plans.
Storm surge and flooding can result in major loss of life. If you do not believe me, check out the Japanese tsunami or Hurricane Sandy. And also check out this incredible video that has been circulating social media this past week. It’s from Super Typhoon Haiyan, which struck the Philippines and killed roughly 4,000 people. Its powerful storm surge swallowed cities whole.
On Monday, November 18 at 1:28 p.m. EST (1728 UTC), NASA will launch its Mars MAVEN mission toward the red planet Mars.
The video is an artist’s concept showing the transition from an ancient, habitable Mars capable of supporting liquid water on its surface to the cold desert world of today.
Today Comet Encke will pass within 0.025 AU of Mercury, followed a day later by Comet ISON at 0.24 AU (1 AU is the distance between the sun and Earth, 150 million km). NASA’s MESSENGER spacecraft, now orbiting Mercury, will turn away from the sun’s innermost planet for a time, to study the two comets.

Hey EarthSky! I wanted to share my timelapse of the New Jersey shore with you. It was taken over the course of 10 months and made up of more than 5,000 photos over the course of more than 40 hours of shooting. I hope you enjoy it …
What corals are, and how some species of coral can seemingly come back… from the dead!
A cool Comet ISON interactive model. The model visualizes the comet’s current position, assumed trajectory, and many important moments as Comet ISON hurtles toward its November 28, 2013 perihelion – or closest approach – to the sun. The model also contains interesting features – such as movement in time or realistic mode. The second view shows the position of ISON in the night sky.
As Voyager 1 recedes from the solar system, researchers are hoping the spacecraft will beam back tones from plasma waves, a form of “interstellar music” that reveals conditions in the realm of the stars.
