Living On the Edge: The Mysterious Lakes of Titan (Part 4)

Titan’s colorful globe passes in front of Saturn and its rings, in this true color image taken in 2011 from NASA’s Cassini spacecraft. The moon’s opaque atmosphere hides a fascinating surface that is rich in methane lakes, water ice, and organic compounds. Image Credit: NASA/JPL-Caltech/Space Science Institute

“On Titan, the molecules that have [...]

Living On the Edge: The Icy Plains of Enceladus (Part 3)

Lit by reflected light from Saturn, Enceladus appears to hover above the gleaming rings with its well-defined ice particle jets spraying a continuous hail of tiny ice grains, in this image taken by NASA’s Cassini spacecraft in 2006 from a distance of 1.303 million kilometers. The 500-km-wide moon has excited the scientific community and [...]

Living On the Edge: The Inviting Waters of Europa (Part 2)

Jupiter’s moon Europa, as seen by NASA’s Galileo spacecraft. A long line of evidence has shown that Europa has an underground ocean of liquid water, which for many scientists constitutes the best place in the Solar System to search for alien life. Image Credit: NASA/JPL/Ted Stryk

“Since ’tis certain that Earth and Jupiter have [...]

Living On the Edge: Life Under the Ice (Part 1)

After drilling through the 800-meter-thick ice sheet that covers subglacial Lake Whillans in western Antarctica, a U.S. research team discovered a thriving microbial ecosystem on the lake floor that hasn’t been reached by sunlight possibly for up to a million years. The image shows the view down the bore hole as the drill melted [...]

Passing the Torch: Twenty-Five Years After Voyager 2, New Horizons Crosses Neptune's Orbit On Its Way to Pluto

Artist’s concept of the New Horizons spacecraft during its planned encounter with Pluto and its moon Charon in 14 July 2015. New Horizons has just completed a major milestone in its mission by crossing the orbit of Neptune on Aug. 25, exactly a quarter-of-a-century after Voyager 2 flew by the ice giant planet in [...]

They Came From Outer Space! The Mystery of the Fast Radio Bursts

The spacecraft tasked with carrying out NASA’s first mission devoted to understanding the Martian upper atmosphere is now just 30 days out from the Red Planet, having so far covered 405 million miles over the last nine months, as it quietly cruises the [...]

Where's the Kaboom? Astronomers Detect No X-Ray Emission From Recent Supernova Explosion

The supernova SN 2014J, as imaged by NASA’s Chandra X-ray Observatory. This image contains Chandra data, where low-, medium-, and high-energy X-rays are red, green, and blue respectively. The boxes in the bottom of the image show close-up views of the region around the supernova in data taken prior to the explosion (left), as [...]

A Troubled Start to a Triumphant Mission: 37 Years Since the Launch of the Voyagers

Voyager 2 begins its journey of exploration, 37 years ago today (20 August), with a rousing liftoff atop a Titan IIIE-Centaur booster from Launch Complex (LC)-41 at Cape Canaveral. Photo Credit: NASA

A quarter-century ago, this week, NASA’s Voyager 2 spacecraft became the first machine fashioned by human hands to travel close to the [...]

Dust in the (Interstellar) Wind: Seven Particles of Possible Interstellar Origin Identified in Samples Returned by NASA's Stardust Spacecraft

A team of researchers has identified seven dust particles that were returned to Earth in 2006 by NASA’s Stardust spacecraft, which might have originated in the interstellar medium. This false-color image shows a diffraction pattern created by one of these particles, named Orion. Image Credit: Zack Gainsforth

Following a preliminary analysis of the dust [...]
