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.

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 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.

Mysterious ‘elves’ and ‘sprites’ seen in Jupiter’s atmosphere
Strange “sprites” or “elves” have been seen on Jupiter from Nasa’s Juno mission. The supernaturally-named phenomena refer to transient luminous events – bright, unpredictable, and bizzaire flashes of light. It is the first time such events have ever been seen on another world, Nasa says. The lights on the solar system’s largest planets were predicted by scientists, who thought that they would be observed in Jupiter’s liquid-like atmosphere.

Jupiter's ocean moons raise tides on each other
Jupiter's "ocean world" moons may have strong gravitational effects on each other, raising big tides in each others' subsurface seas, a new study suggests. Surprisingly, these moon-moon tidal forces might generate more heat in the satellites' oceans than the gravitational tugs of giant Jupiter, study team members found.

Freaky ‘Active’ Object in Jupiter’s Orbit Is First of Its Kind Seen by Astronomers
It’s neither an asteroid nor a comet but something in between. It’s also parked within Jupiter’s orbit, making this object the first of its kind to ever be detected. Say hello to 2019 LD2, the only active Jupiter Trojan known to science. Trojans are a large group of asteroids located in the same orbital path as Jupiter, and they’re all dead, inert asteroids – well, except apparently this one, which now boasts a very comet-like tail, according to a press release put out by the University of Hawaii’s Institute for Astronomy.
