Animation of eruption from Tvashtar Paterae, taken from imagery from the New Horizons probe in 2007

Two images taken by Gallileo over the course of three months showing the shifting regions of lava flow. New Horizons is a Robotic spacecraft mission by NASA currently underway The Galileo probe observed a lava curtain erupting from the small patera in the centre of the image, and the lava lake from the larger one above it. Lava is molten rock expelled by a Volcano during an eruption When first expelled from a volcanic vent it is a Liquid at Temperatures

Tvashtar Paterae compose an active volcanic region of Jupiter's moon Io located near the moon's north pole. This is a sub-article to Io (moon Volcanism on Io, a moon of Jupiter, produces Lava flows volcanic pits and plumes TemplateInfobox Planet.--> Io (ˈaɪoʊ, or as Greek It is a series of paterae, or volcanic craters. A volcanic crater is a circular depression in the ground caused by volcanic activity It is named after Tvashtar, the Hindu god of blacksmiths.

Galileo was an Unmanned spacecraft sent by NASA to study the Planet Jupiter and its moons Named after the Astronomer During this time, a 25 km long, 1 to 2 km high curtain of lava was seen to erupt from one patera, a lake of superheated silicate lava erupted in the largest patera, and finally a plume of gas burst out, rising 385 km above the moon and blanketing areas as far away as 700 km. The kilometre ( American spelling: kilometer) symbol km is a unit of Length in the Metric system, equal to one thousand The Chemical compound silicon dioxide, also known as silica or silox (from the Latin " Silex " is an Oxide ^[2]

An eruption on Tvashtar on February 26, 2007 was photographed by the New Horizons probe as it went past Jupiter en route to Pluto.

New Horizons is a Robotic spacecraft mission by NASA currently underway The probe observed an enormous 290 km (180 miles) high plume from the volcano, with an as-yet unexplained filamentary structure made clearly visible by the background light from the sun. ^[3]
