Cassini's Radar Shows Titan's Young Active Surface

"Unveiling Titan is like reading a mystery novel," said Dr. Charles Elachi, director of NASA's Jet Propulsion Laboratory, Pasadena, Calif., and team leader for the radar instrument on Cassini. "Each time you flip the page you learn something new, but you don't know the whole story until you've read the whole book. The story of Titan is unfolding right before our eyes, and what we are seeing is intriguing."

Possible Origin of Cosmic Rays Revealed with Gamma Rays

A team of UK astronomers working with international partners has produced the first ever image of an astronomical object using high energy gamma rays, helping to solve a 100 year old mystery - the origin of cosmic rays. Their research, published in the Journal Nature on November 4th, was carried out using the High Energy Stereoscopic System (H.E.S.S.), an array of four telescopes, in Namibia, South-West Africa...

Sky Survey Provides New Radio View of Universe

Astronomers using the National Science Foundation's Very Large Array (VLA) have overcome longstanding technical hurdles to map the sky at little-explored radio frequencies that may provide a tantalizing look deep into the early Universe. The scientists have released images and data covering half of the sky visible from the VLA, and hope to complete their survey within a year.

Chandra's find of lonely halo raises questions about dark matter

Dark matter continues to confound astronomers as NASA's Chandra X-ray Observatory demonstrated with the detection of an extensive envelope of dark matter around an isolated elliptical galaxy. This discovery conflicts with optical data suggesting a lack of dark matter around similar galaxies, and raises questions about how galaxies acquire and keep such dark matter halos...

First Close Encounter of Saturn's Hazy Moon Titan

Long hidden behind a thick veil of haze, Titan, the only known moon with an atmosphere, is ready for its close-up on Oct. 26, 2004. This visit by the Cassini spacecraft may settle intense speculation about whether this moon of Saturn harbors oceans of liquid methane and ethane beneath its coat of clouds.
