scibyte36 Saturn Dione

shared by Mars Base on 03 Mar 12 - No Cached
  • NASA spacecraft circling Saturn has discovered a wispy oxygen atmosphere on the ringed planet's icy moon Dione
  • is 5 trillion times less dense than the air at Earth's surface
  • detected by NASA's Cassini spacecraft
  • ...17 more annotations...
  • equivalent to conditions 300 miles (480 kilometers) above Earth
  • one oxygen ion for every 2,550 cubic feet (90,000 cubic meters
  • still enough to qualify as an atmosphere
  • announced Friday (March 2).
  • Dione, in addition to Saturn's rings and the moon Rhea, is a source of oxygen molecules
  • shows that molecular oxygen is actually common in the Saturn system and reinforces that it can come from a process that doesn't involve life
  • Dione is one of Saturn's smaller moons
  • 698 miles (1,123 km) wide
  • orbits Saturn once every 2.7 days
  • distance of about 234,000 miles (377,400 km)
  • roughly the same as that between Earth and its moon
  • The oxygen on Dione may potentially be created by solar photons or high-energy particles that bombard the Saturn moon's ice-covered surface, kicking up oxygen ions in the process, Tokar explained.  Another idea suggests that geologic processes on Dione could feed the moon's atmosphere, researchers added.
  • atmosphere on Saturn's moon Rhea — one similar to that of Dione — was also detected in 2010
  • Dione was discovered in 1684 by astronomer Giovanni Cassini
  • named after the Greek goddess Dione, who the ancient Greek poet Homer described as the mother of the goddess Aphrodite
  • launched the Cassini mission in 1997 and it has been orbiting Saturn since its arrival at the ringed planet in 2004
  • joint effort by NASA and the space agencies of Europe and Italy, has been extended several times, most recently until 2017

Daytime Lightning on Saturn Spotted by Cassini Spacecraft | Space.com - 0 views

shared by Mars Base on 18 Jul 12 - No Cached
  • Cassini orbiter captured the daytime lightning on Saturn as bright blue spots inside a giant storm that raged on the planet last year
  • NASA unveiled the new Saturn lightning photos Wednesday (July 18), adding that the images came as a big surprise
  • The fact that Cassini was able to detect the lightning means that it was very intense."
  • ...9 more annotations...
  • blue filter on the spacecraft's main camera recorded the lightning flashes
  • scientists then exaggerated the blue tint in order to pin down the lightning's location and size
  • analysis of the new images revealed that the energy from the visible lightning flashes alone could have spiked up to 3 billion watts over one second
  • on par with some of the strongest lightning flashes on Earth.  
  • the lightning on Saturn was spotted across a region 100 miles (160 kilometers
  • Cassini spotted eight daytime lightning flashes on Saturn, five in one part of the storm and three in an another
  • storm wrapped completely around Saturn at its peak and is the longest-lived storm ever seen on the ringed planet. It began in December 2010 and lasted about 200 days, finally sputtering out in late June 2011
  • mystery that remains is why the daytime Saturn lightning only turned up in Cassini's blue imaging filter
  • Scientists aren't sure if that means the lightning is actually blue in color, or if it's due to a short exposure time of the camera that helps the camera filter detect the lightning

  • A bright clump spotted orbiting Saturn at the outermost edge of its A ring may be a brand new moon in the process of being born
  • have not seen anything like this before
  • In images acquired with Cassini’s narrow-angle camera in 2013
  • ...7 more annotations...
  • a 1,200-kilometer-long, 10-kilometer-wide arc of icy material was observed traveling along the edge of the A ring
  • The arc is thought to be the result of gravitational perturbations caused by an as-yet unseen embedded object about a kilometer wide — possibly a miniature moon in the process of formation
  • The half-mile-wide object has been unofficially named “Peggy,”
  • According to the team’s paper, Peggy’s effects on the A ring has been visible to Cassini since May 2012
  • Eventually Peggy may coalesce into a slightly larger moon and move outward, establishing its own orbital path around Saturn
  • This is how many of Saturn’s other moons are thought to have formed much further back in the planet’s history
  • While it is possible that the bright perturbation is the result of an object’s breakup rather than formation, researchers are still looking forward to finding out more about its evolution.
