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 mission to send a spacecraft to scour Jupiter's moon Europa for signs of life appears back on track after Hurricane Milton forced a delay.

Venus, Saturn, Jupiter and Mars will appear to line up and be bright enough to see with the naked eye in the first few hours after dark. This weekend, Venus and Saturn get especially cozy.

NASA's Juno spacecraft has again captured stunning images of Jupiter and its moon Io, providing more insights into the solar system's largest planet as it nears its end.

This NASA Hubble Space Telescope image shows the planet Jupiter in a color composite of ultraviolet wavelengths. Released on Nov. 3, 2023, in honor of Jupiter reaching opposition, which occurs when the planet and the sun are in opposite sides of the sky,

Research and development is underway to create robots that can hunt for signs of life in the vast oceans that exist under the thick ice shells of bodies like Europa.

Six planets will be in alignment this weekend, with four of them shining bright in one sweeping view. What to know about the planet parade.

"There are still many things related to planetary formation and the early evolution of young planetary systems that we don't understand."

A rare parade of planets will light up the night sky throughout January. Six planets will be in alignment for the rest of the month – four of which will be visible with the naked eye, Preston Dyches, public engagement specialist at the NASA Jet Propulsion Laboratory and host of NASA's "What's Up" skywatching series, told ABC News.

Venus, Saturn, Jupiter and Mars will be visible together all month after dark, NASA reports. The four planets have been visible together since December and will be visible through February, as well. You may also catch a glimpse of Neptune and Uranus through a telescope, but they won’t be shining as brightly.

Galileo Galilei's telescopic discovery of Jupiter's four moons in 1610 revolutionized astronomy and supported heliocentric theories. Subsequent centuries saw more moons discovered and a focus shift toward Europa,
