listening to the sun

Kasha Patel, NASA’s Goddard Space Flight Center Robert Alexander spends parts of his day listening to a soft white noise, similar to water falling on the outside of a house during a rainstorm. Every once in a while, he hears an anomalous sound and marks the corresponding time in the audio file. Alexander is listening to the sun’s magnetic field and marking potential areas of interest. After only ten minutes, he has listened to one month’s worth of data. Alexander is a PhD...

NASA/JPL NASA's Pluto-bound New Horizons spacecraft has traversed the orbit of Neptune. This is its last major crossing en route to becoming the first probe to make a close encounter with distant Pluto on July 14, 2015. The sophisticated piano-sized spacecraft, which launched in January 2006, reached Neptune's orbit -- nearly 2.75 billion miles (4.4. billion kilometers) from Earth -- in a record eight years and eight months. New Horizons' milestone matches precisely the 25th anniversary...

Voyager 2 Triton Map

redOrbit Staff & Wire Reports - Your Universe Online In honor of the 25th anniversary of Voyager 2’s first up-close look at Neptune and Triton, NASA has “restored” footage obtained by the probe and used it to construct the highest-quality global color map of the moon to date. According to the US space agency, the map was produced by Dr. Paul Schenk, a scientist at the Houston-based Lunar and Planetary Institute (http://www.lpi.usra.edu/) (LPI), and has also been used to...

Hubble Shows Great Red Spot On Jupiter Is Smaller Than Ever Measured

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...

Voyager Celebrates 36 Years In Space
2013-08-20 15:40:23

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
2013-07-15 15:30:53

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...

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...

humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
