Latest Voyager 2 Stories
The journey of NASA's Voyager 1 spacecraft towards interstellar space continued over the weekend, and officials with the US space agency continue to monitor the 35-year-old probe's progress as it grows ever closer to becoming the first man-made instrument to ever leave the solar system.
Celebrating its 35th anniversary in space today, NASA’s Voyager 1 spacecraft is about to cross the threshold of our solar system, to boldly go where no man, nor machine, has ever gone before.
Monday marked the 35 year anniversary of NASA's Voyager 2 spacecraft launching from Earth, and embarking on a venture to go where no spacecraft has gone before.
The levels of high-energy cosmic rays originating from outside our solar system and the levels of lower-energy particles originating from within have been undergoing changes at a faster rate than at any other time in the past seven years.
After several decades of making a lonely journey across our solar system, Voyager 1 has signaled to NASA that it may have reached the edge of interstellar space.
Scientists have seen auroras dancing around above the giant ice planet Uranus by using the Hubble Space Telescope.
The idea of compressing water is foreign to our daily experience. Nevertheless, an accurate estimate of water’s shrinking volume under the huge gravitational pressures of large planets is essential to astrophysicists trying to model the evolution of the universe.
In order to reduce power consumption, mission managers have turned off a heater on part of NASA's Voyager 1 spacecraft, dropping the temperature of its ultraviolet spectrometer instrument more than 23 degrees Celsius (41 degrees Fahrenheit).
In 1977, Jimmy Carter was sworn in as president, Elvis died, Virginia park ranger Roy Sullivan was hit by lightning a record seventh time, and two NASA space probes destined to turn planetary science on its head launched from Cape Canaveral, Fla.
NASA's Voyager 1 spacecraft has entered a new region between our solar system and interstellar space.
Planetary Ring -- A planetary ring is a ring of dust and other small particles orbiting around a planet in a flat disc-shaped region. The most spectacular and famous planetary rings are those around Saturn, but all four of the solar system's gas giant planets (Jupiter, Saturn, Uranus, Neptune) possess ring systems of their own. The origin of planetary rings is not precisely known, but they are thought to be unstable and dissipate over the course of tens or hundreds of millions of...
Planet Triton -- Triton is the planet Neptune's largest moon, discovered by William Lassell in 1846 just 17 days after the planet itself was discovered. It is named after Triton, from Greek mythology. Triton is unique among all large moons in the solar system for its retrograde orbit around the planet (i.e., it orbits in a direction opposite to the planet's rotation). Jupiter's moons Ananke, Carme, Pasiphae and Sinope and Saturn's moon Phoebe also orbit retrograde, but all of them...
Planet Larissa -- Larissa is the fifth of Neptune's known moons. It was discovered by Harold Reitsema based on ground-based stellar occultation observations, and was photographed by Voyager 2 in 1989. Larissa is irregular (non-spherical) in shape and appears to be heavily cratered, with no sign of any geological modification. Little else is known about it. Since its orbit is below Neptune's synchronous orbit radius it is slowly decaying due to tidal forces and will one day break up...
Planet Galatea -- Galatea is the fourth known moon of Neptune, named after the the Nereid of Greek legend. It was discovered in 1989 by Voyager 2 and very little is known about it. It is irregularly shaped and shows no sign of any geological modification. Since its orbit is below Neptune's synchronous orbit radius it is slowly decaying due to tidal forces and will one day break up into a planetary ring or impact on Neptune's surface. ----- Discovery Discovered by Voyager 2...
Planet Despina -- Despina is the third known moon of Neptune. It was discovered in 1989 by Voyager 2, and very little is known about it. It is irregularly shaped and shows no sign of any geological modification. Since its orbit is below Neptune's synchronous orbit radius it is slowly decaying due to tidal forces and will one day break up into a planetary ring or impact on Neptune's surface. ----- Discovery Discovered by Voyager 2 Discovered in 1989 Orbital...
