Johns Hopkins University (JHU) continues to pad its space community résumé with their interactive map, “The map of the observable Universe”, that takes viewers on a 13.7-billion-year-old tour of the cosmos from the present to the moments after the Big Bang. While JHU is responsible for creating the site, additional contributions were made by NASA, the European Space Agency, the National Science Foundation, and the Sloan Foundation.

This five-frame sequence (Repeating Sequence on this video) of New Horizons images captures the giant plume from Io's Tvashtar volcano. Snapped by the probe's Long Range Reconnaissance Imager (LORRI) as the spacecraft flew past Jupiter earlier this year, this first-ever "movie" of an Io plume clearly shows motion in the cloud of volcanic debris, which extends 330 kilometers (200 miles) above the moon's surface. Only the upper part of the plume is visible from this vantage point -- the plume's source is 130 kilometers (80 miles) below the edge of Io's disk, on the far side of the moon. The appearance and motion of the plume is remarkably similar to an ornamental fountain on Earth, replicated on a gigantic scale. The knots and filaments that allow us to track the plume's motion are still mysterious, but this movie is likely to help scientists understand their origin, as well as provide unique information on the plume dynamics. Io's hyperactive nature is emphasized by the fact that two other volcanic plumes are also visible off the edge of Io's disk: Masubi at the 7 o'clock position, and a very faint plume, possibly from the volcano Zal, at the 10 o'clock position. Jupiter illuminates the night side of Io, and the most prominent feature visible on the disk is the dark horseshoe shape of the volcano Loki, likely an enormous lava lake. Boosaule Mons, which at 18 kilometers (11 miles) is the highest mountain on Io and one of the highest mountains in the solar system, pokes above the edge of the disk on the right side. The five images were obtained over an 8-minute span, with two minutes between frames, from 23.50 to 23.58 Universal Time on March 1, 2007. Io was 3.8 million kilometers (2.4 million miles) from New Horizons; the image is centered at Io coordinates 0 degrees north, 342 degrees west. The pictures were part of a sequence designed to look at Jupiter's rings, but planners included Io in the sequence because the moon was passing behind Jupiter's rings at the time.

Jupiter?s moon Io features at least 400 active volcanoes, making it the most volcanically active world in our Solar System.
However, the location of the volcanoes on Io just doesn?t match up with scientific models that predict how the moon?s interior is heated.
?Rigorous statistical analysis of the distribution of volcanoes in the new global geologic map of Io,?
said Christopher Hamilton of the University of Maryland, College Park and the Goddard Spaceflight Center.
?We found a systematic eastward offset between observed and predicted volcano locations that can?t be reconciled
with any existing solid body tidal heating models.?
Uploaded on Apr 30, 2011 A plume erupts from the Io's Tvashtar volcanic area as the moon transits Jupiter. Io's own shadow is visible as a dark disk on the Jupiter's cloud tops. Filaments (from an as yet unexplained mechanism) are visible in the plume. The appearance of Tvashtar's plume was based on this composite of images from the New Horizons spacecraft: Rendered in real time using the VESTA engine.

Published on Apr 25, 2013 The so-called "volcanoes" on Jupiter's moon Io have long been conventionally interpreted as the effect of tidal forces acting on the moon.
But a recent scientific paper has announced that this longstanding explanation does not fit with the actual location of the plumes.
Is it possible that this failure of theory could cause planetary scientists to reconsider the electrical explanation first offered by
astrophysicist Thomas Gold and later by plasma scientists Anthony Peratt and Alex Dessler?

Of Jupiter?s four large Galilean satellites, Io is the closest to the planet.
It?s about the same size as Europa and the Earth?s Moon. It may be the strangest satellite humans have ever studied.
Voyager photos of Io revealed erupting volcanoes. This wasn?t too surprising, because Jupiter?s intense tidal forces heat
the interior of the satellite, just like on Europa. But subsequent observations show that volcanoes are always erupting
on Io - in fact, it?s the most volcanically active world in the solar system! Material shot up by the many volcanoes
rises high above the surface of the little satellite and then falls back in a lazy arc due to Io?s weak gravity.
Volcanic activity adds about 10 centimeters of new material to the surface each year.

On Christmas Eve, as millions upon millions of people focused on wrapping gifts and getting ready for the holidays,
an amateur astronomer gave a small gift to the world. The person turned a telescope and camera to Jupiter and caught volcanic
Io going across the face of the gas giant. This happened just a few days after professional astronomers caught a rare eclipse
involving that very same moon.
Published on Apr 26, 2012 Io is the innermost of the four Galilean moons of Jupiter and, with a diameter of 3,642 kilometers, the fourth-largest moon in the Solar System.
It was named after Io, a priestess of Hera who became one of the lovers of Zeus. Nevertheless, it was simply referred to as Jupiter I, or
The first satellite of Jupiter, until mid-20th century. With over 400 active volcanoes, Io is the most geologically active object in the Solar System. Its surface is dotted with more than 100 mountains,
some which are taller than Earth's Mount Everest. Unlike most satellites in the outer Solar System (which have a thick coating of ice),
Io is primarily composed of silicate rock surrounding a molten iron or iron sulfide core. Although not proven, recent data from the Galileo orbiter indicates that Io might have its own magnetic field Io has an extremely
thin atmosphere made up mostly of sulfur dioxide (SO2). If a surface data or collection vessel were to land on Io in the future,
it would have to be extremely tough (similar to the tank-like bodies of the Soviet Venera landers) to survive the radiation and magnetic fields

Thanks to a mission extension, NASA’s Juno probe continues to orbit Jupiter, being only the second spacecraft in history to do so. Since it arrived around the gas giant on July 5th, 2016, Juno has managed to gather a great deal of information on Jupiter’s atmosphere, magnetic and gravity environment, and its interior structure.

Jupiter’s moon Io is in stark contrast to the other three Galilean moons. While Callisto, Ganymede, and Europa all appear to have subsurface oceans, Io is a volcanic world, covered with more than 400 active volcanoes. In fact, Io is the most volcanically active body in the Solar System.

On May 16, 2023, NASA’s Juno spacecraft flew past Jupiter’s volcanic moon Io, and then the gas giant soon after. Io is the most volcanically active body in the solar system. Slightly larger than Earth’s moon, Io is a world in constant torment. Not only is the biggest planet in the solar system forever pulling at it gravitationally, but so are its Galilean siblings – Europa and the biggest moon in the solar system, Ganymede. The result is that Io is continuously stretched and squeezed, actions linked to the creation of the lava seen erupting from its many volcanoes. This rendering provides a “starship captain” point of view of the flyby, using images from JunoCam. For both targets, Io and Jupiter, raw JunoCam images were reprojected into views similar to the perspective of a consumer camera. The Io flyby and the Jupiter approach movie were rendered separately and composed into a synchronous split-screen video. Launched on Aug. 5, 2011, Juno embarked on a 5-year journey to Jupiter. Its mission: to probe beneath the planet's dense clouds and answer questions about the origin and evolution of Jupiter, our solar system, and giant planets in general across the cosmos. Juno arrived at the gas giant on July 4, 2016, after a 1.7-billion-mile journey, and settled into a 53-day polar orbit stretching from just above Jupiter’s cloud tops to the outer reaches of the Jovian magnetosphere. Now in its extended mission, NASA’s most distant planetary orbiter continues doing flybys of Jupiter and its moons. Visit to learn more.

Jupiter’s moon Io has an extremely volatile environment. But what makes it so active? And is there a magma ocean beneath its frozen crust? Scientist Alfred McEwan is keen to unlock its incredible secrets. Best of Earth Lab: Best of BBC Earth: This is a channel from BBC Studios who help fund new BBC programmes.

Not since the Galileo mission ended 20 years ago have we seen such great images of Io. NASA's Juno spacecraft captured this image with its JunoCam instrument on October 15th from less than 12,000 km altitude. Ted Stryk processed the image. Image Credit: Ted Stryk/NASA/JPL-Caltech/SwRI/MSSS
Those characteristics alone make it interesting. But what really garners Io so much attention, and led Juno to study it more closely, is its volcanic activity. It’s the most geologically active body in the Solar System and boasts over 400 volcanoes, along with widespread lava flows.
