On August 20, 2013 at 4:24 a.m. EDT, the sun erupted with an Earth-directed coronal mass ejection, or CME, a solar phenomenon which can send billions of tons of particles into space that can reach Earth one to three days later. These particles cannot travel through the atmosphere to harm humans on Earth, but they can affect electronic systems in satellites and on the ground.
Experimental NASA research models, based on observations from NASA’s Solar Terrestrial Relations Observatory, show that the CME left the sun at speeds of around 570 miles per second, which is a fairly typical speed for CMEs.

The following is a portion of a statement about the European Southern Observatory’s latest exoplanet discovery from NASA’s Science Mission Directorate Associate Administrator, Dr. John Grunsfeld.
“We congratulate the European Southern Observatory team for making this exciting new exoplanet discovery. For astronomers, the search for exoplanets helps us understand our place in the universe and determine whether Earth is unique in supporting life or if it is just one member of a large community of habitable worlds. NASA has several current and future missions that will continue in this search.”
Scientists have made a biological discovery in Arctic Ocean waters as unexpected as finding a rainforest in the middle of a desert. A NASA-sponsored expedition named ICESCAPE punched through three-feet of sea ice to find waters richer in microscopic marine plants, essential to all sea life, than any other ocean region on Earth.
The microscopic plants, called phytoplankton, are the base of the marine food chain. Phytoplankton were thought to grow in the Arctic Ocean only after sea ice had retreated for the summer. Scientists now think that the thinning Arctic ice is allowing sunlight to reach the waters under the sea ice, catalyzing the plant blooms where they had never been observed.
The finding reveals a new consequence of the Arctic’s warming climate and provides an important clue to understanding the impacts of a changing climate and environment on the Arctic Ocean and its ecology.
The findings were published in the journal Science.
On Sunday, May 20th, the Moon will pass in front of the sun, transforming sunbeams across the Pacific side of Earth into fat crescents and thin rings of light.
In the United States, the eclipse begins around 5:30 pm PDT. For the next two hours, a moon-shaped portion of the sun will go into hiding. Greatest coverage occurs around 6:30 pm PDT.
Solar Eclipse this Weekend
Winter seems to have been on hold this year in some parts of the United States. Snowfall has been scarce in places that were overwhelmed with the white stuff at the same time last year. In this ScienceCast, JPL climatologist Bill Patzert explains what’s going on.

NASA’s New Horizons mission reached a special milestone on Dec. 2, 2011, on its way to reconnoiter the Pluto system, coming closer to Pluto than any other spacecraft.
It’s taken New Horizons 2,143 days of high-speed flight – covering more than a million kilometers per day for nearly six years—to break the closest-approach mark of 1.58 billion kilometers set by NASA’s Voyager 1 in January 1986.
The action begins around 4:45 a.m. Pacific Standard Time when the red shadow of Earth first falls across the lunar disk. By 6:05 a.m. Pacific Time, the moon will be fully engulfed in red light. This event—the last total lunar eclipse until 2014—is visible from the Pacific side of North America, across the entire Pacific Ocean to Asia and Eastern Europe.

Earth is about to pass through a stream of debris from Halley’s comet, source of the annual Orionid meteor shower. Forecasters expect more than 15 meteors per hour to fly across the sky on Saturday morning, Oct. 22, when the shower peaks.

The Curiosity rover is scheduled for launch to Mars on Nov. 25, 2011. To prepare for the launch, a telecon has been scheduled so you can hear about the many resources available for you to share the excitement of launch with your students. Topics during the telecon are:
• Launch details: NASA TV rundown, scheduled press briefings and the Tweetup
• Visuals: images and video
• Educator professional development: workshops, telecons and presentations
• Spacecraft models and other items for loan
Date: Monday, Oct. 10, 2011
Time: Noon PDT (3 p.m. EDT)
Leader: Anita Sohus
Mark your calendar. On May 6th, Earth will pass through a stream of debris from Halley’s comet, producing a mild but beautiful meteor shower known as the “eta Aquarids.”
