Jupiter and Saturn will come within 0.1 degrees of each other, forming the first visible "double planet" in 800 years
Before 2020 comes to a close, Jupiter and Saturn will be so close that they will appear to form a "double planet." The great conjunction, as the planetary alignment has come to be known, hasn't occurred in nearly 800 years. When their orbits align every 20 years, Jupiter and Saturn get extremely close to one another. This occurs because Jupiter orbits the sun every 12 years, while Saturn's orbit takes 30 years — every couple of decades, Saturn is lapped by Jupiter, according to NASA.

A rare conjunction of Jupiter and Saturn will be visible to the naked eye for the first time in 800 years
Jupiter and Saturn are due to converge in their orbits on Monday, appearing as a double planet in the night sky — the first such occurrence in almost 800 years. The two planets have been near one another throughout the year, according to Rice University astronomer Patrick Hartigan. They will reach their closest approach, passing within 0.1 degrees of each other during the winter solstice on December 21, the longest night of the year.

Jupiter could make an ideal dark matter detector
So you want to find dark matter, but you don't know where to look. A giant planet might be exactly the kind of particle detector you need! Luckily, our solar system just happens to have a couple of them available, and the biggest and closest is Jupiter. Researchers Rebecca Leane (Stanford) and Tim Linden (Stockholm) released a paper this week describing how the gas giant just might hold the key to finding the elusive dark matter.

Something big just hit Jupiter
In 1994, the Comet Shoemaker-Levy 9 (SL9) impacted Jupiter, which had captured the comet shortly before (and broken apart by its gravity). The event became a media circus as it was the first direct observation of an extraterrestrial collision of Solar System objects. The impact was so powerful that it left scars that endured for months and were more discernible than Jupiter's Great Red Spot.

Jupiter's Great Red Spot is even deeper than scientists had thought
It's hard to imagine the sheer scale of Jupiter's Great Red Spot from here on Earth, because the storm is so big that it could swallow our planet. Now, it turns out, the Great Red Spot isn't just wide: it's deep too, quite a bit deeper than anybody expected. Data from NASA's Juno spacecraft has shown that the behemoth storm extends as much as 310 miles (500 kilometers) beneath Jupiter's cloud tops. And the Jupiter maelstrom is linked to jets that go far deeper, hinting that the giant planet's upper and lower atmospheres are tied together.

NASA's Juno probe reveals secrets of Jupiter's atmosphere in 3D
A NASA spacecraft is giving the best-ever 3D model of the largest planet of our solar system. The Juno mission is using its second extended phase to peer far into the clouds of Jupiter, using a polar-orbiting view that no previous spacecraft was able to access.

NASA’s Juno Spacecraft ‘Hears’ Jupiter’s Moon
An audio track collected during Jupiter mission’s Ganymede flyby offers a dramatic ride-along. It is one highlights mission scientists shared in a briefing at American Geophysical Union Fall Meeting. Sounds from a Ganymede flyby, magnetic fields, and remarkable comparisons between Jupiter and Earth’s oceans and atmospheres were discussed during a briefing today on NASA’s Juno mission to Jupiter at the American Geophysical Union Fall Meeting in New Orleans.

NASA space telescope spots most powerful light ever seen on Jupiter, helps solve 30-year-old mystery
NASA has detected the most energetic light ever seen on Jupiter and, in the process, solved a 30-year-old mystery. In a new study, researchers using NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) space observatory were able to spot the highest-energy light ever seen on Jupiter. The light, which is X-ray radiation, is also the highest-energy light ever seen on a planet in our solar system other than Earth.

A “hot Jupiter’s” dark side is revealed in detail for first time
MIT astronomers have obtained the clearest view yet of the perpetual dark side of an exoplanet that is “tidally locked” to its star. The planet is WASP-121b, a massive gas giant nearly twice the size of Jupiter.

‘Incredible’ Jupiter images revealed by NASA’s James Webb telescope
Stunning images taken by NASA’s James Webb Space Telescope show Jupiter in new glory. Fifth in line from the sun, Jupiter is the largest planet in our solar system — more than twice as big as all the others combined. If Earth were the size of a grape, Jupiter would be the size of a basketball, NASA says.

Scientists stumped by strange polygon-shaped cyclones on Jupiter
Enormous polygon-shaped cyclone systems at Jupiter’s north and south poles have left scientists baffled over how they maintain their bizarre but beautifully geometric shapes for years. The hurricane-force storms — each the size of the continental United States — have remained inexplicably stable in their strange configurations since they were first discovered by the Juno spacecraft in 2017.

Jupiter is flinging rocks at Earth 'like a sniper', scientist reveals
Jupiter is flinging dangerous comets and asteroids at Earth rather than acting as its shield, a scientist has revealed. A popular theory suggests that Jupiter acts like a gigantic protector in the solar system, sucking or deflecting dangerous debris with its tremendous mass.
