Amateur Astronomers Combine Data to Reveal New Images of Galaxies

April 23, 2014

0 Comments

Amateur astronomers and astrophotographers have combined their optical data with the data from some of the world’s most sophisticated space telescopes to reveal new images of galaxies M101, M81, Centaurus A, and M51. Long before the term “citizen science” was coined, the field of astronomy has benefited from countless men and women who study the […]

Human-T-Lymphocyte (T Cell)

Changes in T-cell behavior quickly occur in space, allowing researchers to more effectively study genetic and molecular changes associated with aging-related immune suppression. Telling someone to “act your age” is another way of asking him or her to behave better. Age, however, does not always bring improvements. Certain cells of the immune system tend to […]

New Technique Provides Near Real-Time Mapping of the Sun’s Interior

April 18, 2014

0 Comments

Using data from NASA’s Solar Dynamics Observatory, researchers have developed a new technique that opens the door for near real-time mapping of the sun’s roiling interior. Like a balloon bobbing along in the air while tied to a child’s hand, a tracer has been found in the sun’s atmosphere to help track the flow of […]

Kepler Discovers Earth-Size Planet Orbiting a Star in the ‘Habitable Zone’

April 18, 2014

0 Comments

Astronomers have discovered the first Earth-size planet orbiting a star in the “habitable zone,” confirming that Earth-size planets exist in the habitable zones of other stars and signaling a significant step closer to finding a world similar to Earth. Using NASA’s Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting a star in […]

Hubble Image Reveals Cross-Section View of the Universe

April 17, 2014

1 Comment

This newly released Hubble image provides a cross-section view of the Universe, showing objects at different distances and stages in cosmic history. An image of a galaxy cluster taken by the NASA/ESA Hubble Space Telescope gives a remarkable cross-section of the Universe, showing objects at different distances and stages in cosmic history. They range from […]

New Study Presents “Water World” Theory for the Emergence of Life

April 16, 2014

1 Comment

A new study describes how electrical energy naturally produced at the sea floor might have given rise to life, assembling decades of field, laboratory and theoretical research into a grand, unified picture. Life took root more than four billion years ago on our nascent Earth, a wetter and harsher place than now, bathed in sizzling […]

New Modeling Reveals that Tilted Orbits Could Make More Worlds Habitable

April 16, 2014

7 Comments

New research from astrobiologists at NASA’s Goddard Space Flight Center reveals that large amplitude, high frequency obliquity oscillations on Earth-like exoplanets can suppress the ice-albedo feedback, increasing the outer edge of the habitable zone. Pivoting planets that lean one way and then change orientation within a short geological time period might be surprisingly habitable, according […]

Researchers Discover the First Exomoon Candidate

April 11, 2014

0 Comments

By using gravitational microlensing and taking advantage of chance alignments between stars, an international team of researchers has spotted the first signs of an exomoon. Titan, Europa, Io and Phobos are just a few members of our solar system’s pantheon of moons. Are there are other moons out there, orbiting planets beyond our sun? NASA-funded […]

Cassini Views the Lakes of Saturn’s Moon Titan

April 10, 2014

0 Comments

Using a spectral filter, NASA’s Cassini spacecraft views the lakes of Saturn’s moon Titan. The Cassini spacecraft peers down through layers of haze to glimpse the lakes of Titan’s northern regions. Titan (3,200 miles, or 5,150 kilometers across) has a hydrological cycle similar to Earth’s, but instead of water, Titan’s lakes and seas are filled […]

Curiosity Image Captures Mysterious Bright Spot

April 9, 2014

0 Comments

A newly released Curiosity image shows a bright spot on the surface of Mars, which was possibly caused by the sun glinting off a rock or cosmic rays striking the camera’s detector. Images taken by NASA’s Curiosity Mars rover on April 2 and April 3 include bright spots, which might be due to the sun […]

Hubble Measures “El Gordo” Galaxy Cluster, Bigger Than Previously Thought

April 4, 2014

0 Comments

Researchers have measured the mass of the El Gordo Galaxy Cluster, calculating the cluster’s mass to be as much as 3 million billion times the mass of our sun. NASA’s Hubble Space Telescope has weighed the largest known galaxy cluster in the distant universe, cataloged as ACT-CL J0102-4915, and found it definitely lives up to […]

Fermi Data Reveal New Clues to Dark Matter

April 4, 2014

1 Comment

New maps from the Fermi-LAT Collaboration show that the galactic center produces more high-energy gamma rays than can be explained by known sources, suggesting that this excess emission is consistent with some forms of dark matter. A new study of gamma-ray light from the center of our galaxy makes the strongest case to date that […]
