At the edge of our solar system in December 2004, the Voyager 1 spacecraft encountered something never before experienced during its then 26-year cruise through the solar system "” an invisible shock formed as the solar wind piles up against the gas in interstellar space. This boundary, called the termination shock, marks the beginning of our solar system's final frontier, a vast expanse of turbulent gas and twisting magnetic fields. A NASA-sponsored team is developing a way to view...

NASA's sun-focused STEREO spacecraft unexpectedly detected particles from the edge of the solar system last year, allowing University of California, Berkeley, scientists to map for the first time the energized particles in the region where the hot solar wind slams into the cold interstellar medium. Mapping the region by means of neutral, or uncharged, atoms instead of light "heralds a new kind of astronomy using neutral atoms," said Robert Lin, UC Berkeley professor of physics and lead for...

San Francisco, CA. - NASA's Voyager 2 spacecraft has followed its twin Voyager 1 into the solar system's final frontier, a vast region at the edge of our solar system where the solar wind runs up against the thin gas between the stars. However, Voyager 2 took a different path, entering this region, called the heliosheath, on August 30, 2007. Because Voyager 2 crossed the heliosheath boundary, called the solar wind termination shock, about 10 billion miles away from Voyager 1 and almost a...

DETROIT, June 27 /PRNewswire-USNewswire/ -- One of the fastest sailboats on the Great Lakes - Earth Voyager - arrived in Detroit this week as part of a 13-city tour highlighting the need to restore the Great Lakes. "We're drawing attention to how important the Great Lakes are to our economy and way of life," said Jeff Skelding, national campaign director of the Healing Our Waters-Great Lakes Coalition, the boat tour's sponsor. "Yet every day, our lakes face serious threats, which is why we...

SAN FRANCISCO--New observations from the edge of our solar system show what scientists have suspected for several years: The solar system is squashed. The edge of the solar system is roughly where the solar wind runs up against thin gas found between the stars in the rest of the Milky Way. This "wind," actually a thin gas of electrically charged particles, blows outward in all directions from the sun at between 1 million and 2 million mph, forming a bubble called the...

Scientists have discovered that our sun's 'atmosphere' is asymmetric, thanks to two champion spacecraft For the second time in history, a spacecraft still communicating with Earth has reached the solar system's final frontier, a vast region at the edge of our solar system where the solar wind smashes into the thin gas between the stars. NASA's Voyager 2 probe crossed the solar-wind "termination shock" on Aug. 30, which is 30 years and 10 days after the spacecraft launched from Cape...

A mission that was supposed to last just five years is celebrating its 30th anniversary this fall. Scientists continue to receive data from the Voyager 1 and 2 spacecraft as they approach interstellar space. The twin craft have become a fixture of pop culture, inspiring novels and playing a central role in television shows, music videos, songs and movies from the 1980s and 1990s. Many of these fictional works focus on what would happen if an alien race were able to locate Earth via Voyager's...

Images taken by Cassini's Magnetospheric Imaging Instrument (MIMI) show that Saturn's ring current is a warped disc that balloons out of the equatorial plane on the planet's dayside and remains a thin disk that rises above the plane at larger distances on the nightside.  Dr Stamatios "Tom" Krimigis, the Principal Investigator for the instrument, who is presenting images at the European Planetary Science Congress in Potsdam on Thursday 23rd August, said, "Ring currents surround planets...

PASADENA, Calif. - NASA's two venerable Voyager spacecraft are celebrating three decades of flight as they head toward interstellar space. Their ongoing odysseys mark an unprecedented and historic accomplishment. Voyager 2 launched on Aug. 20, 1977, and Voyager 1 launched on Sept. 5, 1977. They continue to return information from distances more than three times farther away than Pluto. "The Voyager mission is a legend in the annals of space exploration. It opened our eyes to the scientific...

Ancient explorers set sail expecting to encounter dragons on the world's unknown oceans. NASA's twin Voyager spacecraft are searching for dragons of a different sort as they enter the boundary of our solar system "“ cosmic "dragons" that breathe a strange fire of high-speed atomic fragments called cosmic rays. Just as mythical dragons were expected to inhabit stormy seas, these cosmic dragons could be found among turbulent magnetic fields powered by the colliding winds of stars,...

Heliopause -- The heliopause is the boundary where our Sun's solar wind is stopped by the interstellar medium. The solar wind blows a "bubble" in the interstellar medium (the rareified hydrogen and helium gas that permeates the galaxy). The point where the solar wind's strength is no longer great enough to push back the interstellar medium is known as the heliopause, and is often considered to be the outer "border" of the solar system. The distance to the heliopause is not precisely...

Saturn's moon Pandora -- Pandora [pan-DOR-uh] is the fourth of Saturn's known satellites. It was discovered from photographs taken by Voyager during its encounter with Saturn by S. Collins and others. Pandora is the outer shepherd satellite for Saturn's F-ring. It has a diameter of about 114 by 84 by 62 kilometers (71 by 52 by 38 miles) and appears to be very heavily cratered. The two largest craters are about 30 kilometers (19 miles) in diameter. No linear valleys or ridges are...

Saturn's moon Prometheus -- Prometheus [pra-MEE-thee-us] is the third of Saturn's known satellites. It was discovered from photographs taken by Voyager during its encounter with Saturn by S. Collins and others. Prometheus acts as a shepherd satellite for the inner edge of Saturn's F Ring. The moon is extremely elongated about 145 by 85 by 62 kilometers (90 by 53 by 39 miles) in diameter. It has a number of ridges and valleys on its northern side. Several craters about 20...

Saturn's moon Atlas -- Atlas, the second of Saturn's known satellites, orbits near the outer edge of the A-ring and is about 40 by 20 kilometers (25 by 15 miles) in size. It is probably a shepherd satellite for Saturn's A-ring. Atlas was discovered by R. Terrile in 1980 from photographs taken by Voyager during its encounter with Saturn. ----- Discovered by: R. Terrile/Voyager 1 Date of Discovery: 1980 Distance from Saturn: 137,670 km Radius: 18.517.213.5 km Orbital...
