NASA's Voyager 1 spacecraft discovered active volcanoes on Jupiter's moon Io. Before Voyager 1 flew by Io, scientists believed the moon to be a dead world much like Earth's moon. The mission discovered the volcanoes somewhat by accident.

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,

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.

There are 8 planets in our solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Naptune. The solar system formed about 4.6 billion years ago from a cloud of interstellar gas and dust. The planets, asteroids, and comets orbit the sun in elliptical paths.

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.

"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."

Astronomers using the James Webb Space Telescope have discovered complex atmospheric shifts in SIMP 0136, a free-floating planetary object. Findings i

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.
