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.

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

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.

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.

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,

As the largest planet in our solar system, Jupiter reflects a lot of the Sun’s light even though it is more than five times farther from the Sun than Earth.

Scientists studying samples that NASA collected from the asteroid Bennu found a wide assortment of organic molecules that shed light on how life arose.

Samples returned from an asteroid contain a surprising abundance of the basic ingredients of life. They were discovered to be rich in carbon, nitrogen and ammonia, with over 30 kinds of amino acids and the five nucleobases found in RNA and DNA. 1 The asteroid, Bennu, was targeted by a Nasa mission that returned a capsule to Earth in September 2023.

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