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 …

Jupiter flashes pulsating southern pole, boffins understandably baffled

Jupiter’s vivid northern and southern lights flash independently from each other, a discovery that has surprised scientists. The results published in Nature Astronomy on Monday reveal that the gas giant’s x-ray emissions are erratic at its north pole; the swirling patterns of light continuously brighten and dim over time. But …

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 …

Astronomers fire up AI algorithms to hunt Milky Way's hot Jupiters

Astronomers have uncovered a potential treasure trove of hot Jupiters, a rare class of exoplanet, in our galaxy. Hot Jupiters are a type of gas giant. They are physically similar to the Jupiter in our Solar System, and stay close to their parent star, completing their orbits in about a week. It is estimated that only one per …

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 …

NASA plans seven-year trip to Jupiter – can we come with you, please?

Vid NASA has OKed two new missions to study some of the most interesting asteroids in our solar system, as part of its ongoing Discovery mission program. The first mission, named Lucy, will launch in October 2021 and will head off to the gas giant of Jupiter to explore its Trojan zones. These are two points on either side of the …

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 …

Just what Europe needs – another bungled exit: Mars lander goes AWOL

It's not a great day for space watchers. The European Space Agency's Schiaparelli Mars lander may have failed during its descent to the Red Planet. Meanwhile, NASA's Juno spacecraft orbiting Jupiter has gone into "safe mode" unexpectedly. The Schiaparelli lander was carried to Mars from Earth by the ESA's Trace Gas Orbiter ( …

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 …

Jovian moon Io loses its atmosphere every day

If you've ever resented crunching frost underfoot on a cold morning, spare a thought for Jupiter's moon Io: when it's in eclipse, the frost on the ground is a big chunk of its atmosphere. That's the conclusion of research that looked at Io's atmosphere: when it passes behind Jupiter, Io cools down from a balmy -235°F (-148°C) …

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 …

NASA peers through its SpeX: Aha! Jupiter's globe-warming hotspot

Jupiter’s Great Red Spot may be responsible for stirring an atmospheric hotspot into a frenzy, causing it to be hundreds of degrees warmer than anywhere else on the planet. Researchers from Boston University and the University of Leicester have published new evidence in Nature which shows Jupiter’s atmosphere may be driven by …
