Behold the volcano-blanketed moon, Io.
After swooping by Jupiter’s tortured moon on Feb. 3, NASA‘s Juno spacecraft beamed again a few of the closest-ever pictures of this distinctive world. The company’s deep house probe got here inside simply 930 miles (1,500 kilometers) of Io, following an analogous cross simply over a month in the past. Planetary scientists hope these much-anticipated flybys will reply basic questions concerning the mysterious, lava-spewing moon.
“The dual flybys are designed to supply new perception into how Io’s volcanic engine works and whether or not a worldwide magma ocean exists beneath Io’s rocky, mountainous floor terrain,” mission operators wrote after the primary pictures got here again.
Io accommodates tons of of volcanoes, lots of that are energetic and scorching sufficient for Juno to detect their warmth on the moon’s floor. A few of the distinguished mound-like volcanoes are simply seen within the pictures beneath, as are darker areas the place lava could have considerably just lately flowed.
These spectacular views are processed (eradicating noise and distortion, and so on.) by each skilled and novice picture processors, a few of whom work for NASA or associated house analysis applications. These are the closest views of Io captured in over 20 years. (Extra pictures might be added as they grow to be accessible.)

Io is blanketed in erupting volcanoes as a result of it is relentlessly locked in a tug-of-war between close by objects, together with the colossal Jupiter. “Not solely is the most important planet within the photo voltaic system perpetually pulling at it gravitationally, however so are Io’s Galilean siblings — Europa and the most important moon within the photo voltaic system, Ganymede,” NASA defined in a press release. “The result’s that Io is constantly stretched and squeezed, actions linked to the creation of the lava seen erupting from its many volcanoes.”
In current months, the Juno craft has noticed clear indicators of exercise on Io, together with a hazy plume it noticed over the volcano Prometheus. NASA’s Galileo mission additionally captured a plume above these fields of lava within the yr 2000.
“It’s the purest type of discovery.”
Planetary scientists will pour over these newest pictures within the coming weeks, months, and years. The brand new views and knowledge may reveal whether or not or not a lava ocean sloshes beneath Io’s hardened lava crust.
“It’s the purest type of discovery,” Ashley Davies, a planetary scientist at NASA’s Jet Propulsion Laboratory who researches Io, advised Mashable in November 2023. “We’re seeing issues that we’ve by no means seen earlier than.”
This story was up to date with extra new pictures of the Jovian moon Io.
