April is the Cruelest Month
April 13, 2012
One year after the historic tornado outbreak of April 27-28, 2011, researchers say they've learned a few things about deadly twisters. Today's story from Science@NASA presents some of the scientific findings that emerged from the swath of destruction.
Mysteries of the Sun
April 10, 2012
NASA has just released five new videos called "Mysteries of the Sun". The videos describe the science of the sun and its effects on the solar system and Earth.
A Spiral Galaxy in Hydra
April 10, 2012
This image from the NASA/ESA Hubble Space Telescope shows NGC 4980, a spiral galaxy in the southern constellation of Hydra. The shape of NGC 4980 appears slightly deformed, something which is often a sign of recent tidal interactions with another galaxy.
NASA Extends Kepler, Spitzer, Planck Missions
April 6, 2012
NASA extended Spitzer and Kepler for two additional years; and the U.S. portion of Planck, a European Space Agency mission, for one year.
Dark Heart of a Cosmic Collision
April 6, 2012
The peculiar galaxy Centaurus A as seen in longer infrared wavelengths and X-rays. Inner structural features seen in this image are helping scientists to understand the mechanisms and interactions within the galaxy, as are the jets seen extending over thousands of light years from the black hole believed to be at its heart.
Venus Invades the Pleiades
April 2, 2012
This week, Venus and the Pleiades star cluster will meet in the sunset sky for a rare and beautiful conjunction.
Getting to Know the Goldilocks Planet
March 29, 2012
With NASA's Kepler spacecraft discovering alien worlds at a record pace, it seems to be just a matter of time before an Earth-sized planet is found in the "Goldilocks zone"--that is, in an orbit sized just right for liquid water and life. In today's story from Science@NASA, researchers discuss how they'll explore a cousin of Earth many light years away.
Is it Snowing Microbes on Enceladus?
March 27, 2012
Is it snowing microbes on Enceladus? The idea is not so far-fetched, say researchers, as evidence mounts for a "uniquely accessible" habitable zone on Saturn's icy moon.
Closest Pass Yet over Enceladus South Pole
March 27, 2012
NASA's Cassini spacecraft is preparing to make its lowest pass yet over the south polar region of Saturn's moon Enceladus, where icy particles and water vapor spray out in glittering jets. The closest approach, at an altitude of about 46 miles (74 kilometers), will occur around 11:30 a.m. PDT (2:30 p.m. EDT) on March 27.
Hubble Sees Glittering Jewels of Messier 9
March 26, 2012
The NASA/ESA Hubble Space Telescope has produced the most detailed image so far of Messier 9, a globular star cluster located close to the center of the galaxy. This ball of stars is too faint to see with the naked eye, yet Hubble can see over 250,000 individual stars shining in it.
