Jupiter

Astronomers use Hubble and Spitzer to forecast tonight's hot Jupiter weather report: cloudy with a chance of rocks.

ESA's Juice deep-space probe has captured an image of Jupiter and its four largest moons – even though it won't launch for three years.

NASA has given the official go-ahead for the Europa Clipper deep-space mission to make a detailed survey of one of Jupiter's largest moons. The unmanned mission can now proceed to its final design phase ahead of the building and testing of the spacecraft and its instruments.

Data from the Juno probe found that Jupiter's core is less dense and more spread out than expected. Now, astronomers believe they have an answer – a huge ancient planet, with 10 times the mass of Earth, crashed into the gas giant in the early days of the solar system.

The Hubble Space Telescope has captured a detailed view of the largest planet in our solar system – the gas giant Jupiter. The portrait, which was captured on June 27, highlights the complex nature of Jupiter’s cloud surface, and showcases the gas giant’s most famous feature – the Great Red Spot.

A new study by Caltech and NASA's Jet Propulsion Laboratory in Pasadena, California indicate that the subterranean world ocean on Jupiter's moon Europa may be more Earthlike than scientists believed, with the waters containing common salt.

A key element of NASA's Europa Clipper is being put through its paces as a prototype of the probe's High-Gain Antenna (HGA) undergoes testing at the Experimental Test Range (ETR). The HGA will be used to keep the Clipper in contact as it conducts a series of flybys of Jupiter's moon Europa.

As the largest planet in the solar system by a wide margin, Jupiter has a lot of sway, but its history is still a bit of a mystery. Now astronomers have put forward a new theory, suggesting that the gas giant formed much farther away from the Sun and then migrated into its current position.

Earth’s pleasant, life-giving atmosphere is turning out to be somewhat of an oddity. To get a better understanding of exoplanets, a team at NASA’s Jet Propulsion Laboratory (JPL) has recreated one of these alien atmospheres in the lab.

The Sun is setting on 2018, and with so many eyes on (and in) the skies it’s been a stellar year for space photography. From mesmerizing nebulae to historic firsts to stunning views of Earth and other planets, New Atlas rounds up some of the best space photos of the year.

A type of world dubbed a "hot Neptune" has been conspicuously few and far between in terms of exoplanet discoveries, but a new observation may explain why. Hubble has now spotted a hot Neptune named GJ 3470b that’s vanishing at a record rate.

NASA's Juno orbiter is approaching the halfway mark of its science mission. On December 21 at 8:49:48 am PST (11:49:48 am EST), the spacecraft will complete the 16th of 32 scheduled science orbits in a flyby that will bring it within 3,140 mi (5,053 km) of the planet's cloud tops.
