Hubble Shows Great Red Spot On Jupiter Is Smaller Than Ever Measured
2014-05-15 03:13:20

NASA Jupiter's trademark Great Red Spot -- a swirling anti-cyclonic storm larger than Earth -- has shrunk to its smallest size ever measured. According to Amy Simon of NASA's Goddard Space Flight Center in Greenbelt, Maryland, recent NASA Hubble Space Telescope observations confirm the Great Red Spot now is approximately 10,250 miles across. Astronomers have followed this downsizing since the 1930s. Historic observations as far back as the late 1800s gauged the storm to be as large...

Lee Rannals for redOrbit.com - Your Universe Online Thirty-six years ago NASA launched one of the longest missions in the space agency's history, the Voyager 2. The Voyager 2 spacecraft is a sister spacecraft of the Voyager 1 and was designed to explore not only planets like Jupiter, Saturn, Uranus and Neptune, but also the edge of our Solar System. Voyager 2 was able to give NASA an up-close look at Saturn and its moons. The 36-year-old spacecraft made its first flyby of Jupiter...

New Neptune Moon

Lee Rannals for redOrbit.com - Your Universe Online According to NASA, the Hubble Space Telescope has revealed that Neptune has been hiding another moon, bringing the total count of moons orbiting the planet to 14. The new moon, named S/2004 N 1, is no more than 12 miles across, making it the smallest known moon in the Neptunian system. NASA said this moon is so small that it is about 100 million times fainter than the faintest star that can be seen with the naked eye. The moon is so...

NASA's Jet Propulsion Laboratory A gauge on the Voyager home page tracks levels of two of the three key signs scientists believe will appear when the spacecraft leave our solar neighborhood and enter interstellar space. When the three signs are verified, scientists will know that one of the Voyagers has hurtled beyond the magnetic bubble the sun blows around itself, which is known as the heliosphere. The gauge indicates the level of fast-moving charged particles, mainly protons,...

NASA Celebrates 40th Anniversary Of Pioneer 11

[ Watch the Video: Pioneer 11 Animation and Archive Footage ] Michael Harper for redOrbit.com — Your Universe Online NASA is celebrating the 40th birthday of the Pioneer 11 spacecraft. For the past four decades, Pioneer has been hurtling through space, capturing satellite images of the planets Jupiter and Saturn. As its predecessor, Pioneer 10 had launched just over a year before and was the first spacecraft to not only leave the inner Solar System, but make the trip to Jupiter as...

Voyager 1 Continues Its Journey

Lee Rannals for redOrbit.com - Your Universe Online NASA´s Voyager 1 spacecraft may have allegedly left the confines of our solar System after 35 years and more than 11 billion miles of traveling through space. Scientists writing in the Geophysical Research Letters claim that they measured drastic changes in radiation levels on August 25, 2012 while the spacecraft was sitting over 11 billion miles away from the Sun. The anomalous cosmic rays (those trapped in the outer heliosphere)...

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...
