"It's exciting because we've wondered for long a time whether giant planets like Jupiter and Saturn can form around such small stars."

Scientists: This massive gas planet should not exist

Red Dwarf Mystery

A team of astronomers spotted a gigantic Jupiter-like world orbiting a relatively tiny star. It's way too big to be orbiting the star.

Scientists: This Massive Gas Planet Should Not Exist

It's way too big to be orbiting this tiny star.

See the shadow of the moon Io fall upon Jupiter.

Juno captures stunning images of a solar eclipse on Jupiter

Moon Shot

While performing a close flyby of Jupiter, NASA's Juno spacecraft captured several stunning images of a solar eclipse on the gas giant.

Jupiter's moon Io casts a *really* big shadow.

The closest planned flyby will have the spacecraft approach Europa to an altitude of just 16 miles.

NASA is sending a probe to Jupiter's icy moon to look for life

Icy Moon Flyby

NASA has announced it's completing the final designs and planning for constructing and testing a spacecraft that will visit Jupiter's icy moon Europa.

NASA is Sending a Probe to Jupiter’s Icy Moon to Look for Life

Europa's ocean of salty water is one of the most promising places in the solar system to look for life.

An ancient collision is scientists' best explanation for the planet's unusually diffuse core.

Jupiter may have absorbed a smaller planet

Hard Science

Scientists suggest that Jupiter may have collided with and absorbed a giant protoplanet when the solar system was forming some 4.5 billion years ago.

Jupiter May Have Absorbed a Smaller Planet

Did the solar system's largest planet eat one of its siblings?

And an amateur astronomer was able to capture it on camera.

Something enormous just smashed into Jupiter

Big Hit

Jupiter got hit by something so big on Wednesday that a photographer was able to capture the impact using a telescope in his backyard.

"I've never seen anything like that before."

Blade-shaped arms are growing out of the storm as it swirls.

Jupiter's Great Red Spot is dying

Jupiter Ending

NASA scientists report that Jupiter's Great Red Spot is shrinking and that it could totally dissipate within the next 20 years.

Jupiter’s Great Red Spot Is Dying

The iconic oval storm could dissipate in a matter of decades.

"I can imagine organisms anchored to the sea floor or the ice benefiting from these waves."

The moons of Jupiter and Saturn could have Earth-like tidal waves

Off World

New calculations suggest that two of Jupiter and Saturn's moons could have active tidal waves, much like those here on Earth, under their thick icy shells.

The Moons of Jupiter and Saturn Could Have Earth-Like Tidal Waves

New finding bolsters the case for alien life.

These new planets are massive. So is what they could teach us.

Time to Shine, CI Tau

CI Tau is a small star. But new research shows that its planets are absolute units, dwarfing the largest planets in our own system by an enormous margin.

These New Planets Are Massive. So Is What They Could Teach Us.

One of them is 10 times the size of Jupiter, but whips around its star every nine days.

Here’s Why Finding Water On Other Planets is So Important

The planet could host much more water than Earth.

There's water in Jupiter's atmosphere

Based on data from two ground-based telescopes, researchers believe there's water on Jupiter, perhaps far more than on Earth.
