JUPITER

If it completes the crucial orbit insertion process on July 4, the solar-powered spacecraft will spend 18 months around the gas giant.

Kepler-1647b, a gas giant located 3,700 light-years from Earth, orbits two stars — one slightly larger and the other slightly smaller than our sun.

At its closest point May 30, the planet will be seen with the naked eye, appearing like a red star that will outshine Sirius, the brightest star in our sky.

The ratio of oxygen and hydrogen on Earth and Europa are surprisingly similar, bolstering chances that life may exist on the Jovian moon.

The planets, all of them Earth-sized, are locked in orbit around a faint dwarf star merely 40 light-years away.

On Tuesday, NASA released images, captured by its Chandra X-ray Observatory, showing gigantic "northern lights" on Jupiter.

The giant planet is orbiting a brown dwarf that's located 5 billion million miles away.

It's been over a decade since the five visible planets lined up in the pre-dawn sky.

The mysterious bright spots on the dwarf planet's surface that have long baffled scientists may be a mixture of salt and water-ice, a new study suggests.

The planetary trio formed by Venus, Mars and Jupiter pursuing their normal orbit around the sun will be visible until Thursday.

Images captured by NASA's Hubble Space Telescope reveal Jupiter's famous "Great Red Spot" in unprecedented detail, and the presence of a rare wave-like structure in the planet's northern hemisphere.

Europa is one of the four largest moons hovering near Jupiter and is inundated with radiation from the giant gas planet.

"The evidence says no one's out there," said world-renowned NASA scientist William Borucki.

The young exoplanet -- first to be discovered using the Gemini Planet Imager -- is the most "Jupiter-like" planet ever seen.

The space agency would used the drones to study weather patterns on gas planets, researchers say.

The exoplanet has a mass very similar to that of Jupiter, while the composition of the host star HIP 11915 is also similar to that of the sun.

The test comes after NASA's Jet Propulsion Laboratory deployed the drone known as Bruie beneath a frozen lake in Alaska.

NASA's ambitious mission to look for alien life on the Jovian moon has now officially moved from the concept stage to the development phase.

Just when you got used to Mercury Retrograde -- here comes the June full moon.

Jupiter was believed to have acted like a wrecking ball to destroy inner planets in the early solar system, a new study suggests.

Extraterrestrial life may not consist of grey creatures with large black eyes, but NASA thinks there may be different types of living organisms on Europa.
