Yet another result from Cassini mission. During a close flyby on March 12, the spacecraft tasted and sampled a surprising organic brew erupting in geyser-like fashion from Saturn’s moon Enceladus. New heat maps of the surface show higher temperatures than previously known in the south polar region, with hot tracks running the length of giant […]

NASA’s Cassini spacecraft has discovered evidence that points to the existence of an underground ocean of water and ammonia on Saturn’s moon Titan. The findings made using radar measurements of Titan’s rotation will appear in the March 21 issue of the journal Science.
According to Ralph Lorenz, lead author of the paper and Cassini radar […]

After more than a decade of preparation, the world’s most powerful telescope, known as Large Binocular Telescope (LBT) is now looking skyward with both of its massive eyes wide open.
Not only is it the largest binoculars but it also is the world’s most powerful telescope in the world. Located on a remote mountain […]

Ulysses, the mission to study the Sun’s poles and the influence of our star on surrounding space is coming to an end. After more than 17 years in space – almost four times its expected lifetime – the mission is finally succumbing to its harsh environment and is likely to finish sometime in the next […]

This picture taken by MESSENGER spacecraft shortly after its closest approach to Mercury on January 14, 2008. The spacecraft’s Narrow Angle Camera (NAC) on the Mercury Dual Imaging System (MDIS) instrument acquired this image as part of a mosaic that covers much of the sunlit portion of the hemisphere not viewed by Mariner 10. Images […]

Since last discovery on this month’s Mars asteroid impact, numerous tracking measurements from four different observatories has been received. Unfortunately (or fortunately to Mars), new data have led to a significant reduction in the position uncertainties during the asteroid’s close approach to Mars on Jan. 30, 2008. As a result, the impact probability has dropped […]

How do planetary systems form? How common are they? What is their architecture? How many habitable earth-like planets exist in the Milky Way? In the past decade, astronomers have clearly come closer to finding answers to these exciting questions. With the discovery of the first planet orbiting another Sun-like star in 1995, the field of […]

An asteroid estimated to be 164-feet wide is expected to cross Mars’ orbital path early next year. Observations provided by the astronomers and analyzed by NASA’s Near-Earth Object Office at the Jet Propulsion Laboratory in Pasadena, Calif., indicate the object may pass within 30,000 miles of Mars at about 6 a.m. EST on Jan. 30, […]

This composite image shows the jet from a black hole at the center of a galaxy striking the edge of another galaxy, the first time such an interaction has been found. X-rays from Chandra (colored purple), optical and ultraviolet (UV) data from Hubble (red and orange), and radio emission from the Very Large Array (VLA) […]

Though didn’t seem very sharp, this picture has amazing stories to reveal. The picture shows a baby star, 1,149 light-years away from our Earth, blowing two massive “bubbles”. But instead of bubble gum, this youngster, called HH 46/47, is using powerful jets of gas to make bubbles in outer space.
The infant star can be […]
