On Dec. 27, 2024, NASA's Juno spacecraft swooped by the volcanic world Io. It witnessed a giant eruption.

Loki Patera is 202 kilometres (126 mi) in diameter, covers 20,000 sq km (7,700 sq mi), and was the largest volcanic feature found on Io until these new observations revealed the hot spot in the south polar region. The new hot spot covers 100,000 sq km (40,000 sq mi).

NASA is tracking a truck-sized asteroid which is set to hurtle by Earth today at many times the velocity of a speeding bullet. The space rock—dubbed "2025 BV5"—is estimated by NASA's Jet Propulsion Laboratory to be some 26 feet across.

Io, Jupiter’s fiery moon, just erupted with enough energy to power Earth six times over! NASA’s Juno mission captured this mind-blowing event, revealing a hidden world beneath the surface. What does this mean for space exploration?

Known as the "Parade of Planets," the celestial event will feature appearances from Mars, Jupiter, Uranus, Venus, Neptune and Saturn through the end of January, according to Farmer's Almanac. Mercury will emerge in the night sky at the end of February, replacing Saturn.

Jupiter's Great Red Spot storm, which usually appears dark-red, can be seen shining a lurid blue color in an ultraviolet image of the planet.

NASA’s Juno mission found Io’s biggest volcanic eruption ever. The explosion was stronger than all Earth’s power plants combined.

Jupiter’s moon Io is the most volcanically active world in the Solar System. The gravitational tug-of-war between Jupiter and its other large moons squeezes Io so that its interior is molten. That magma finds its way to the surface in lava lakes and volcanic eruptions.

The data used to create the image is from a Hubble Space Telescope project to capture and map Jupiter's superstorm system.

Since completing its primary science objectives in orbit of Jupiter, Juno has been conducting flybys of the Jovian moons Io, Europa, Ganymede, and Callisto. The spacecraft completed two very close flybys in 2023 and 2024,
