Juno finds some lightning on Jupiter is the polar opposite to bolts here on Earth

Data from the Juno spacecraft currently orbiting Jupiter has shown the highly unusual nature of lightning on the gas giant, according to two new studies published in Nature on Wednesday. We've known that Jupiter has lightning for nearly 40 years, after the first probes went out there. But Juno has discovered that these natural …

Juno's July fly-by gave NASA a close-up of the Great Red Spot

video It's at least 150 years old, one-and-a-half Earths wide, reaches 300 km (around 200 miles) into Jupiter's atmosphere – and now, thanks to data from the Juno probe, NASA's offering the chance to take a virtual dive into the famous Great Red Spot. When it made its first pass over the vast super-storm in July 2017, one of the …

Juno beams back first closeups of Jupiter's unsightly red acne

NASA has released the first closeup images of Jupiter’s Great Red Spot, the massive storm system that has been swirling on its surface for over 180 years. On July 10, the Juno space probe swooped within 5,600 miles (9,010 kilometers) of Jupiter’s surface, directly over the storm system. Now the pictures are back and the space …

Uber's New York competitor sued over driver equity scheme

Drivers of Uber-competitor Juno have taken out a class action lawsuit against the company, claiming that it ripped them off with an equity ownership scheme that was designed to attract them to the service. When it launched in early 2016, the New York City company came up with a novel way to attract drivers to its service – …

Juno's first data causing boffins to rewrite the text books on Jupiter

Scientists were expecting a lot of new data from the Juno space probe orbiting Jupiter, and they haven't been disappointed. The most massive planet in the Solar System is turning out to have a lot of surprises. In a press conference on Thursday, NASA engineers and astrophysicists detailed the first science results from the …

Jun-OH-NO! NASA's Jupiter probe in busted helium-valve drama

NASA's Juno probe will not venture any closer to Jupiter, and will stay in its current 53-day orbit for the remainder of its mission. That's due to faulty helium valves in the propulsion system, space boffins announced today. The spacecraft has been circling the gas giant since July 2016. NASA scientists had planned to fire …

Juno how to adjust a broken Jupiter probe's orbit?

NASA's revealed that its Juno probe has made another close pass around Jupiter, but sadly remains in a longer-than-planned orbit that means it spends more time a long way away from the gas giant. On February 2nd the probe sailed just 4,300 kilometres (2,670 miles) over the gas giant's cloud tops, capturing lots of lovely …

It's ALIVE: Juno back online after reboot

NASA's Juno space probe has successfully rebooted after a recent Jupiter fly-by was disrupted by an unexpected “safe-mode” event. The data-gathering on the October 19 flyby didn't happen, because a software performance monitor rebooted its computer just beforehand. The probe then entered safe mode while NASA worked through its …

Juno probe has tech trouble, cancels orbital re-adjustment

The Juno probe orbiting Juipter has some trouble with its propulsion feed system and plans for the craft's stay at the gas giant are therefore being revisited. "Telemetry indicates that two helium check valves that play an important role in the firing of the spacecraft's main engine did not operate as expected during a command …

What the hex is up with Jupiter's North Pole?

Jupiter doesn't have a colossal hexagon at its North Pole, unlike it celestial cousin Saturn. So says NASA after the six megabytes of data the Juno probe collected last weekend finally made it to Earth after requiring a day-and-a-half to download. One of the downloads was the image at top, which those of you who want more …

Jovial NASA says Juno flyby a success

It was a hats-in-the-air weekend at NASA, with the agency announcing its Juno probe's first close-up Jupiter fly-by was a success. The probe has now started the agonisingly slow process of downloading the data collected on its Sunday swoop (closest approach was 13:44 UTC, August 28; adjust as your local timezone dictates). …

Juno probe to graze Jupiter on Saturday

Strap in for a bumpy ride, Earthlings: the Juno probe will make its closest approach to Jupiter on Saturday when it comes within just 4,200km of the gas giant's uppermost clouds. Juno made it to Jupiter in early July but was busy entering orbit and fiddling with its rockets so didn't do much more than shoot some rather nice …

Juno shoots 'Marble Movie' of Jupiter

NASA has gifted blinded space fanciers another glimpse of Jupiter through its Juno cameras. The images were snapped as the Juno probe swings back towards Jupiter in the first of two long elliptical orbits it will use to slow itself down before getting down to serious snapping. NASA says it would not have ordinarily taken the …

Juno turns around and heads off to graze Jupiter's clouds

The Juno is on its way back to Jupiter after successfully reaching 'apojove', the high point of its first orbit of the gas giant. And now the craft is heading for its closest encounter with Jupiter. Juno's mission plan called for it to enter the planet's gravitational sphere of influence and slow down by making two “capture …

By Juno! NASA delivers first new snaps from Jupiter

NASA has released the first images captured by the Juno probe. The space agency says the image below was captured on July 10th from a distance of “4.3 million kilometers … on the outbound leg of its initial 53.5-day capture orbit.” The probe's “JunoCam”, a colour, visible-light camera, collected the image. While it may …

Juno probe spins up its sonic screwdrivers for Jupiter flyby

NASA is firing up the nine scientific instruments on board the Juno probe orbiting Jupiter ahead of its first data collection mission. The spacecraft successfully went into orbit around the solar system's largest resident on July 4 after a five-year trip and has used some of the instruments already to take pictures as it …

By Jove! NASA's Juno prepares to slip into orbit around Jupiter

NASA's Juno spacecraft is set to enter its most critical stage as it attempts to fly into Jupiter’s orbit. At 4:18am BST, NASA’s Juno spacecraft will begin its orbital insertion burn, a move that will decelerate its velocity – slow enough to be captured by Jupiter’s gravitational field. The burn will initiate when the …

Jupiter's throwing a firework party for Juno – and Hubble's peeking in

The Hubble Space Telescope has captured new images of Jupiter’s glowing aurora swirling around one of the planet’s poles, as part of a wider observation programme of the gas giant. NASA’s Juno spacecraft is expected to descend into Jupiter on 5 July at 0418 BST, when Mission Juno will commence. The trip to Jupiter is part of a …
