Waves of lava seen in Io’s largest volcanic crater
Taking advantage of a rare orbital alignment between two of Jupiter’s moons, an advantage of a rare orbital alignment between two of Jupiter’s moons, Io and Europa, researchers have obtained an exceptionally detailed map of the largest lava lake on Io, the mProfitant of a rare Orbital alignment between deux des Jupiter Monday, Io et Europa, Les chercheurs ont. Taking advantage of a rare orbital alignment between two of the moons of Jupiter, Io and Europe, the researchers have obtained an exceptionally detailed map of Io’s largest lava lake, the mProfitant of a rare orbital alignment between deux des Mon of Jupiter, Io et Europe, Les chercheurs ont une carte d’exceptionnellement du plus grand lac de lave sur le, le corps le plus volcaniquement actif du système solaire.
Le 8 mars 2015, Europe est passée devant Io, bloquant progressivement la lumière de la lune volcanique. It seems that the surface of Europe is the coating of the drop of water, it reflects very little sunlight to the infrared waves, which allows researchers to isolate with precision the despair of volcanoes on the surface of Io.
Les données infrarouges ont montré that the temperature of the surface of the fondue massif of an autre extrémité de l’autre suggests that the lave renversée dans deux vagues qui ont chacun balayé d’ouest in est a environ Kilometer (3 300 pieds) par jour .
The ad reading is a popular explanation for the periodic linking and assembly of the hot spot, called Loki Patera after dieu nordique. (The patera is a volcanic cratère in the shape of a bowl.) The volcanic site is more actif sur, which is more volcanically actif du système solaire, Loki Patera est à environ 200 kilomètres (127 milles). The region of the patera to an area of 21,500 kilometers races, larger than Lake Ontario.
When the Voyager space Voyager 1 et 2 came to 1979, it is devenu évident that cell était dû à des éruptions volcaniques à la surface. Astronomes terrestrial ont d’abord remarqué la luminosité changeante d’Io dans les années 1970, plus seulement. Malgré’s highly detailed images of NASA’s Galileo mission at the end of the 1990s and the early 2000s, astronomy continues to debate and the lights of Loki Patera – which occur every 400 to 600 days – are dues La Renée la lave dans un lave massif ou À des éruptions périodiques Wash the cabbage on a large surface.
“If Loki Patera is a worthy person, she is a man more than a million times living in a bond of nature,” a declared Katherine de Kleer, a UC Berkeley graduate student and the lead author of L ‘musical exercise. “Dans ce scénario, des pièces de crête fraîche tombent, exposant magma incandescent in dessous et provoquant an éclat dans l’infrarouge”.

On March 8, 2015, Europe passed Io, gradually blocking the light of the volcanic moon. Because the surface of Europe is coated with water ice, it reflects very little sunlight at infrared wavelengths, allowing researchers to accurately isolate the heat emanating from the volcanoes on the surface of Io.
Infrared data showed the surface temperature of Io’s massive molten lake increased steadily from one end to the other, suggesting that the lava had turned into two waves that each swept from west to east at about one kilometer (3,300 feet) per day.
Volcano lava is a popular explanation for the newspaper’s lighting and dimming hot spot, called Loki Patera after the Norse god. (A patera is a bowl-shaped volcanic crater.) The most active volcanic site on Io, which in itself is the most volcanically active in the solar system, Loki Patera is about 200 kilometers (127 miles) in diameter. The warm region of the patera has an area of 21,500 square kilometers, larger than Lake Ontario.
Earthbound astronomers first observed Io’s shifting brightness in the 1970s, but it was only when the Voyager 1 and 2 spacecraft flew in 1979 that this was due to volcanic eruptions on the surface. Despite the highly detailed images of NASA’s Galileo mission in the late 1990s and early 2000s, astronomers continue to debate whether Loki Patera’s glows – which occur every 400 to 600 days – are due to rollover of lava in a huge lava or periodic eruptions that spread the The researchers have obtained an exceptionally detailed map of the largest lava lake on Io, the mProfitant of a rare orbital alignment between deux des Jupiter Monday, Io et Europa, les chercheurs ont Rare orbital alignment between two of the moons of Jupiter, Io and Europe, researchers have obtained an exceptionally detailed map of Io’s largest lava lake, the mProfitant d’un al
