Europa’s sea-life? Just became likely with NASA’s salt ocean findings.

NASA laboratory experiments suggest the dark material coating some geological features of Jupiter’s moon Europa is likely sea salt from a subsurface ocean, discolored by exposure to radiation. The presence of sea salt on Europa’s surface suggests the ocean is interacting with its rocky seafloor — an important consideration in determining whether the icy moon […]

Chances for life on Saturn’s moon Enceladus rise dramatically.

NASA’s Cassini spacecraft has provided scientists the first clear evidence that Saturn’s moon Enceladus exhibits signs of present-day hydrothermal activity which may resemble that seen in the deep oceans on Earth. The implications of such activity on a world other than our planet open up unprecedented scientific possibilities. “These findings add to the possibility that […]

Ceres, Ho!

NASA’s Dawn spacecraft has become the first mission to achieve orbit around a dwarf planet. The spacecraft was approximately 38,000 miles (61,000) kilometers from Ceres when it was captured by the dwarf planet’s gravity at about 4:39 a.m. PST (7:39 a.m. EST) Friday. Mission controllers at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California received […]

Mars held more water than Earth’s Arctic Ocean . . . from wet world to dead planet.

A primitive ocean on Mars held more water than Earth’s Arctic Ocean, according to NASA scientists who, using ground-based observatories, measured water signatures in the Red Planet’s atmosphere. Scientists have been searching for answers to why this vast water supply left the surface. Details of the observations and computations appear in Thursday’s edition of Science […]

My Favourite Picture by Andy Bollan (article).

I love this picture. I first saw it on NASA’a APOD website http://apod.nasa.gov/apod  roughly 10 years ago. It looks like a candle on the altar of science or a giant arrow pointing onwards and upwards. Like Turner’s Fighting Temeraire, it shows the sun setting on a glorious technological period of time. This rocket is about […]

NASA’s empire of a thousand worlds.

How many stars like our sun host planets like our Earth? NASA’s Kepler Space Telescope continuously monitored more than 150,000 stars beyond our solar system, and to date has offered scientists an assortment of more than 4,000 candidate planets for further study — the 1,000th of which was recently verified. Using Kepler data, scientists reached […]

Galaxy-frying X-ray burst from Milky Way’s supermassive black hole core.

Astronomers have observed the largest X-ray flare ever detected from the supermassive black hole at the center of the Milky Way galaxy. This event, detected by NASA’s Chandra X-ray Observatory, raises questions about the behavior of this giant black hole and its surrounding environment. The supermassive black hole at the center of our galaxy, called […]

There and back again . . . NASA’s Orion flies.

NASA marked a major milestone Friday on its journey to Mars as the Orion spacecraft completed its first voyage to space, traveling farther than any spacecraft designed for astronauts has been in more than 40 years. “Today’s flight test of Orion is a huge step for NASA and a really critical part of our work […]

Clear skies and water vapour found on alien exoplanet.

Astronomers using data from three of NASA’s space telescopes – Hubble, Spitzer and Kepler – have discovered clear skies and steamy water vapor on a gaseous planet outside our solar system. The planet is about the size of Neptune, making it the smallest planet from which molecules of any kind have been detected. Now, where’s […]

The mountains of Mars.

NASA’s Mars Curiosity rover has reached the Red Planet’s Mount Sharp, a Mount-Rainier-size mountain at the center of the vast Gale Crater and the rover mission’s long-term prime destination. “Curiosity now will begin a new chapter from an already outstanding introduction to the world,” said Jim Green, director of NASA’s Planetary Science Division at NASA […]
