Lucy is preparing for a close encounter with the asteroid Donaldjohanson, a key milestone before its groundbreaking journey to the Jupiter Trojans. This flyby serves as a crucial test of its optical navigation system,

CNN’s Kaitlan Collins caught up with DJ Daniel, the 13-year-old cancer survivor honored by President Donald Trump during his address to Congress. Almost everything you could want to know about Jupiter's biggest moon, Ganymede.

I showcase some of the most amazing photos you will see of Jupiter, as well as discuss it's magnetic field, core, bands, aurora, atmosphere, storms and clouds.

Previous examinations using ground-based tools as well as the Hubble and Spitzer space telescopes indicated SIMP 0136 was potentially a brown dwarf —a cosmic body with the makings of a star that nonetheless fails to gather enough mass to initiate nuclear fusion.

The world’s premier space observatory has spotted a mysterious and huge, free-floating planetary-mass object that’s “just 20 light-years from Earth,” NASA announced. Researchers recently used the James Webb Space Telescope to study the atmosphere of this “Super Jupiter,” dubbed SIMP 0136.

Mars, Jupiter and Saturn are frequently seen in the night sky. But because Venus and Mercury orbit closer to the sun than Earth, with smaller, faster orbits, it's more rare for them to make an appearance, according to NASA. Venus is visible for only a few ...

In late January this year, NASA’s Psyche spacecraft turned its cameras to the sky and captured some incredible images. The twin cameras onboard, part of the spacecraft’s imaging system, photographed the planets Mars and Jupiter, along with Jupiter’s moons - Io, Ganymede, Callisto, and Europa.

NASA’s twin Voyager probes, which launched in 1977, are the longest-running missions to send data home. But as their power supplies wane, scientists are saying goodbye to one instrument on each spacec

The first major event of Europa Clipper's journey to Jupiter takes place this weekend as a gravity assist maneuver around the Red Planet.

If there was a contest for the most interesting moon in our solar system, Callisto would be a contender. Jupiter's second-largest moon has more impact craters on its surface than any other planetary body in the entire solar system and has tons of ice on its surface.

"It's like a game of billiards around the solar system, flying by a couple of planets at just the right angle and timing to build up the energy we need to get to Jupiter and Europa."

Dust off your old telescope on a clear night and look up. If you find Jupiter, you’ll likely see four small dots to the side of the gas giant: they are the Galilean moons, four of the 95 natural satellites around the Solar System’s largest planet.
