Life on Titan… plastic based?

NASA’s Cassini spacecraft has detected propylene, a chemical used to make food-storage containers, car bumpers and other consumer products, on Saturn’s moon Titan. This is the first definitive detection of the plastic ingredient on any moon or planet, other than Earth. A small amount of propylene was identified in Titan’s lower atmosphere by Cassini’s Composite […]

Cloud spotting on Kepler-7b.

Astronomers using data from NASA’s Kepler and Spitzer space telescopes have created the first cloud map of a planet beyond our solar system, a sizzling, Jupiter-like world known as Kepler-7b. The world is marked by high clouds in the west and clear skies in the east. Previous studies from Spitzer have resulted in temperature maps […]

NASA to Mars: Who (or ‘what’) is hiding the methane now?

Data from NASA’s Curiosity rover has revealed the Martian environment lacks methane. This is a surprise to researchers because previous data reported by U.S. and international scientists indicated positive detections. The roving laboratory performed extensive tests to search for traces of Martian methane. Whether the Martian atmosphere contains traces of the gas has been a […]

Earth is not alone… there’s another blue planet.

Astronomers making visible-light observations with NASA’s Hubble Space Telescope have deduced the actual color of a planet orbiting another star 63 light-years away. The planet is HD 189733b, one of the closest exoplanets that can be seen crossing the face of its star. Hubble’s Space Telescope Imaging Spectrograph measured changes in the color of light […]

NASA versus asteroids. Can humanity survive?

NASA announced Tuesday a Grand Challenge focused on finding all asteroid threats to human populations and knowing what to do about them. The challenge, which was announced at an asteroid initiative industry and partner day at NASA Headquarters in Washington, is a large-scale effort that will use multi-disciplinary collaborations and a variety of partnerships with […]

Neutron star is full of secrets…

Astronomers using NASA’s Swift X-ray Telescope have observed a spinning neutron star suddenly slowing down, yielding clues they can use to understand these extremely dense objects. A neutron star is the crushed core of a massive star that ran out of fuel, collapsed under its own weight, and exploded as a supernova. A neutron star […]

Hurricanes of Saturn.

NASA’s Cassini spacecraft has provided scientists the first close-up, visible-light views of a behemoth hurricane swirling around Saturn’s north pole. In high-resolution pictures and video, scientists see the hurricane’s eye is about 1,250 miles (2,000 kilometers) wide, 20 times larger than the average hurricane eye on Earth. Thin, bright clouds at the outer edge of […]

Surprises in star formation, finds NASA.

Researchers using the airborne Stratospheric Observatory for Infrared Astronomy (SOFIA) have captured the most detailed mid-infrared images yet of a massive star condensing within a dense cocoon of dust and gas. The star is G35.20-0.74, commonly known as G35. It is one of the most massive known protostars and is located relatively close to Earth […]

Strange new structures in space discovered by NASA.

NASA’s Van Allen Probes mission has discovered a previously unknown third radiation belt around Earth, revealing the existence of unexpected structures and processes within these hazardous regions of space. Previous observations of Earth’s Van Allen belts have long documented two distinct regions of trapped radiation surrounding our planet. Particle detection instruments aboard the twin Van […]
