More than a thousand years before the first telescopes, Babylonian astronomers tracked the motion of planets across the night sky using simple arithmetic. But a newly translated text reveals that these ancient stargazers also used a far more advanced method, one that foreshadows the development of calculus over a…
Juno is cruising ever-closer to Jupiter, and mission scientists are asking for your help in finding the most interesting spots on the gas giant to focus their cameras once the spacecraft arrives later this year.
Are you awake before dawn? Good. Go outside. Look east. Bask in the astronomical wonder of seeing all the brightest planets out at the same time, pinpricks of worlds drifting up from the horizon. Missed it? Try again any morning for the next month.
Juno broke the interplanetary distance record for solar-powered spacecraft on Wednesday morning. The Jupiter explorer is close to half a billion miles from the Sun, setting a new standard for using solar power for deep space exploration.
Jupiter, that blustery ball of noxious gas, is probably the last place that comes to mind when you hear the words “life supporting.” But for twenty years, astronomers have suspected Jupiter of doing just that: supporting life on Earth, by shielding us from destructive comets. Now, one scientist is saying that’s dead…
Saturn’s satellite Dione is less than half the size of our moon, and it orbits a planet which features a radius nine times that of Earth. It’s a stark contrast in size that’s beautifully conveyed in a picture recently captured by the Cassini space probe.
Our biggest planet in the solar system is also one of the best: it’s got crazy weather systems, it’s probably saved Earth from enormous impacts, and it’s got hundreds of moons orbiting it. The Atlantic goes over all the ways Jupiter is their favorite planet.
Using data acquired by the Hubble Space Telescope, scientists at NASA have updated their maps of Jupiter. The new images—shown in 4K ultra high definition—reveal changes to the Great Red Spot and rare waves not seen since the Voyager 2 mission.
Astronaut Scott Kelly has been providing us some spectacular images during his time in orbit, but this shot might be one of the coolest ones thus far: Venus, Earth, Jupiter and the Moon, all in the frame.
Astronomical conjunctions occur when celestial objects appear close to one another in the night sky—this happens all the time and they’re not particularly unusual. But a conjunction happening tonight is notable in that it involves two very bright planets—Venus and Jupiter—and they’ll be closer together than they’ve…
Last week, NASA’s Messenger spacecraft ended its 11-year mission by crashing into Mercury. Of course, Messenger was doomed anyway, but sometimes a mission’s entire point is to smash one thing into a bigger thing and watch the explosion.
Most planetary systems are made up of a few rocky super-planets orbiting extremely close to their stars, making our system — multiple, distant bodies — an oddball outlier. And according to new research, Jupiter could be to blame (thank?).
By studying the subtle shifts of aurorae on Ganymede, scientists working with the Hubble Space Telescope have concluded that Jupiter's largest moon hosts a massive subterranean ocean. Quite suddenly, the outer reaches of our solar system appear to be a very wet place, indeed.
It's not just old rock albums that get remastered when technology moves on: this image of Jupiter's ice-covered moon, Europa, has just been given a revamp by scientists from NASA.
According to exobiologists at NASA, these mysterious shrimp and its symbiotic bacterium may hold clues "about what life could be like on other planetary bodies." It's life that may be similar—at the basic level—to what could be lurking in the oceans of Europa, deep under the icy crust of the Jupiter moon.

It is not pleasant inside the core of Jupiter—or any other planet for that matter. However, gaining a better understanding of what's going on in there is key for understanding how these planets form. That's why a team of scientists at Lawrence Livermore National Laboratory recently used diamonds and lasers to recreate…
Scientists have noticed something dramatic happening in the Solar System: Jupiter's famous Great Red Spot, the crimson monster storm that once was so large that it could eat three Earths, is mysteriously shrinking at high speed. Now it's only the width of one Earth. Would it disappear in a few decades?
NASA scientists says that the largest moon in the solar system may harbor life in its inner oceans. Previously, scientists thought Ganymede only had one ocean between two ice layers, but data reveals that its structure is "ice and oceans stacked up in several layers like a club sandwich."
Jupiter is not only the largest planet in our solar system, it's also arguably the most stunning. Those massive storms—including that enormous red eye—produce quite an atmospheric show. And as a cheaper alternative to a giant telescope, this tiny desktop-sized version of Jupiter lets you stare in awe at the gas giant…
