During Pioneer 10's fly-by of Io, the spacecraft performed a radio occultation experiment by transmitting an S-band signal as Io passed between it and Earth. A slight attenuation of the signal before and after the occultation showed that Io had an ionosphere , suggesting the presence of a thin atmosphere with a pressure of 1.0 × 10 −7 bar ...
Volcanism on Io, a moon of Jupiter, is represented by the presence of volcanoes, volcanic pits and lava flows on the surface. Io's volcanic activity was discovered in 1979 by Linda Morabito, an imaging scientist working on Voyager 1. [1] Observations of Io by passing spacecraft and Earth-based astronomers have revealed more than 150 active ...
Io (/ ˈ aɪ. oʊ /), or Jupiter I, is the innermost and second-smallest of the four Galilean moons of the planet Jupiter.Slightly larger than Earth's moon, Io is the fourth-largest moon in the Solar System, has the highest density of any moon, the strongest surface gravity of any moon, and the lowest amount of water by atomic ratio of any known astronomical object in the Solar System.
Io (Jupiter I) is the innermost of the four Galilean moons of Jupiter; with a diameter of 3642 kilometers, it is the fourth-largest moon in the Solar System, and is only marginally larger than Earth's moon.
Loki Patera on moon Io (artist's concept; 0:18). [1] Map of temperature and crust age of Loki Patera obtained by the Large Binocular Telescope. Loki Patera / ˈ l oʊ k i ˈ p æ t ə r ə / is the largest volcanic depression on Jupiter's moon Io, 202 kilometres (126 mi) in diameter. [2] It contains an active lava lake, with an episodically ...
On Feb. 7, several sanctuary cities, led by San Francisco and including Portland, New Haven, Santa Clara and Kings County, sued the Trump Administration, alleging that they are unlawfully coercing ...
The atmosphere of Io is the extremely thin blanket of gases surrounding Jupiter's third largest moon Io. The atmosphere is primarily composed of sulfur dioxide (SO 2), along with sulfur monoxide (SO), sodium chloride (NaCl), and monoatomic sulfur and oxygen. [1] Dioxygen is also expected to be present. Auroral glows in Io's upper atmosphere.
The names are a combination of a name of a person or place derived from the Greek mythological story of Io, Dante's Inferno, or from the name of a nearby feature on Io surface and an approved descriptive term. The descriptive terms, or categories, used for these mountains depends on their morphology, which is a reflection of the mountain's age ...
