Solar Wind, Moon Dust and Martian Lights
Apr 16, 2012 09:13 AM E
The Canadian Space Agency has funded a University of Alberta-led project to study the effects of solar winds on Earth's moon and on Mars. The results are anticipated to influence design of spacecraft for robotic and human exploration.

Designing the Interplanetary Web
Apr 14, 2012 16:26 PM E
Reliable Internet access on the Moon, near Mars or for astronauts on a space station? How about controlling a planetary rover from a spacecraft in deep space? These are just some of the pioneering technologies that ESA is working on for future exploration missions.

Hubble Sees Messier 70: Tight and Bright
Apr 14, 2012 15:57 PM E
In this image, the NASA/ESA Hubble Space Telescope has captured the brilliance of the compact center of Messier 70, a globular cluster. Quarters are always tight in globular clusters, where the mutual hold of gravity binds together hundreds of thousands of stars in a small region of space. Having this many shining stars piled on top of one another ...
NASA's Swift Sees Comet Garradd
NASA's Swift Monitors Departing Comet Garradd
Apr 13, 2012 16:32 PM E
An outbound comet that provided a nice show for skywatchers late last year is the target of an ongoing investigation by NASA's Swift satellite. Formally designated C/2009 P1 (Garradd), the unusually dust-rich comet provides a novel opportunity to characterize how cometary activity changes at ever greater distance from the sun.
Yuri Gagarin
Yuri Gagarin – Hero of the Soviet Union and First Ambassador to the Cosmos
Apr 13, 2012 11:20 AM E
On 12 April 1961 marks the 51st anniversary of one of the most historic moments in human history. It was on this day in 1961, that Soviet cosmonaut Yuri Gagarin became the first human to take a journey into outer space. Aboard his Vostok spacecraft, not only did Gagarin become the first person in space, he also was the first to orbit the Earth - so...

Teamwork: IBEX and TWINS Observe a Solar Storm
Apr 13, 2012 10:23 AM E
On April 5, 2010, the sun spewed a two million-mile-per-hour stream of charged particles toward the invisible magnetic fields surrounding Earth, known as the magnetosphere. As the particles interacted with the magnetic fields, the incoming stream of energy caused stormy conditions near Earth. Some scientists believe that it was this solar storm tha...

Webb Science: The End of the Dark Ages: First Light and Reionization
Apr 13, 2012 09:04 AM E
Until around 400 million years after the Big Bang, the Universe was a very dark place. There were no stars, and there were no galaxies. Scientists would like to unravel the story of exactly what happened after the Big Bang. The James Webb Space Telescope will pierce this veil of mystery and reveal the story of the formation of the first stars and galaxies in the Universe.

Do Solar Storms Cause Heat Waves on Earth?
Apr 13, 2012 06:59 AM E
Although solar flares, and associated coronal mass ejections, can bombard Earth's outermost atmosphere with tremendous amounts of energy, most of that energy is reflected back into space by the Earth's magnetic field. Because the energy does not reach our planet's surface, it has no measurable influence on surface temperature.

Poor spring Rain Projected in Africa
Apr 12, 2012 14:38 PM E
Spring rains in the eastern Horn of Africa are projected to begin late this year and be substantially lower than normal. From March - May, the rains are expected to total only 60 to 85 percentage of the average rainfall in this region. This is a significant deterioration compared to earlier forecasts.

NASA to Fly Deep Space Atomic Clock to Improve Navigation Technology
Apr 12, 2012 12:31 PM E
When people think of space technologies, many think of high-tech solar panels, complex and powerful propulsion systems or sophisticated, electronic guidance systems. Another critical piece of spaceflight technology, however, is an ultra stable, highly accurate device for timing - essential to NASA's success on deep-space exploration missions.

World's Greatest Piggyback Ride
Apr 11, 2012 13:06 PM E
Imagine flying from Florida to D.C. with nowhere to sit, no air conditioning, no place to store your bags -- not even a bathroom. Imagine flying anywhere under those conditions.
Linear Dunes of the Caprivi Strip
Linear Dunes of the Caprivi Strip
Apr 11, 2012 10:40 AM E
In far northeastern Namibia, there is a skinny stretch of land sandwiched between Angola, Botswana, and Zambia. The Caprivi Strip receives more than 600 millimeters (24 inches) of mean annual rainfall and experiences periodic floods, making it almost moist compared to the much drier parts of the country.
Wildfire Spreads Smoke Across Florida
Wildfire Spreads Smoke Across Florida
Apr 10, 2012 13:17 PM E
A large fire in Osceola National Forest has burned more than 10,000 acres and sent smoke wafting across Northeast Florida. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA's Aqua satellite captured this view of the County Line Fire and its smoke on April 7, 2012.
