Latest Occultation Stories
Observing a very rare occultation of a star by Pluto's satellite Charon from three different sites, including Paranal, home of the VLT, astronomers were able to determine with great accuracy the radius and density of the satellite to the farthest planet.
By watching a distant star as it passed behind Saturn's outer rings, Cornell University astronomers on NASA's Cassini-Huygens mission to Saturn have found the most direct evidence to date of patterns, called gravitational wakes, within the planet's outer rings.
The Cassini spacecraft has obtained the most detailed look ever at Saturn's rings, including the B ring, which has eluded previous robotic explorers. Its structure seems remarkably different from its two neighbors, rings A and C. The origin of Saturn's rings is a mystery.
The Cassini spacecraft is about to embark on a new mission phase that will give it a ringside seat at Saturn -- literally. After concentrating on flybys of the stately planet's moons since arriving last year, Cassini will begin five months of extensive study of Saturn's magnificent rings.
It may seem strange now, but in June, the sun didn't set until 8:45 p.m. It's six months later, and the sun sinks below the horizon shortly after 5 p.m. Our number of daylight hours clearly has shrunk. On the first day of summer, it reached its annual maximum for Roanoke at 14 hours 44 minutes.
