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.

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,

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.

Amateur Astronomer Stumbles Upon Something Strange That Contradicts Previous Models of Jupiter's Atmospheric Composition An amateur astronomer's innovative use of old traditional observation techniques has challenged long-held beliefs about Jupiter's cloud composition,

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.

Six planets will form a rare planetary alignment in the night sky on Jan. 21; here is everything you need to know about the 'planet parade' including how to watch it at night.

Mars, Venus, Jupiter, and Saturn can be spotted without special equipment, with Uranus and Neptune requiring a telescope.

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

These are the planets that will be visible with the naked eye. 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,

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.

A six-planetary alignment will occur around Jan. 21. Venus, Mars, Jupiter, Saturn, Uranus, and Neptune will appear in one ecliptic plane in the southern and eastern sky after sunset; however, only Mars, Jupiter, Venus, and Saturn will be visible to the naked eye. You will need a telescope to see Uranus and Neptune.
