New high-definition imagery captured of Jupiter by NASA’s Juno spacecraft is revealing colorful, lighting-like bursts of energy in the upper atmosphere of our solar system’s largest planet.

The phenomena – haunting, jellyfish-like spurts of red lightning dubbed “sprites” and glowing disks known as “elves” – are common occurrences in the upper reaches of the Earth’s atmospheres during thunderstorms, and were first discovered in 1989. Since then, they have been sighted over every continent besides Antarctica.

Scientists have theorized that any planet that has lightning would also produce these super-fast electrical bursts that occur up to 60 miles up in the Earth’s sky, reaching toward space. Researchers predicted that this would certainly be the case in Jupiter’s massive, roiling atmosphere.

However, nobody had ever seen these bright, transient luminous events dancing across alien skies – until now.

Since 2016, Juno has orbited Jupiter and collected troves of images of its aurorae through the spacecraft’s ultraviolet light, or ultraviolet spectrograph instrument (UVS). When scientists began processing some of these images, they noticed an unexpected detail: bright, narrow streaks of ultraviolet emissions that appeared in a flash before quickly vanishing.

“In the process of putting together those images, we noticed that very occasionally we saw these surprising, short-lived, bright flashes,” said Juno scientist Rohini Giles during a Tuesday press conference at the annual meeting of the American Astronomical Society’s Division for Planetary Sciences, according to Business Insider.

“We then went and searched through all of the data that we’ve taken over four years of the mission and we found a total of 11 flashes all with very similar properties,” she added. The outbursts only lasted mere milliseconds.

On Tuesday, her team published a new study on these phenomena in the Journal of Geophysical Research: Planets.

Here on Earth, sprites often resemble alienlike jellyfish-style creatures dangling from the ionosphere, or the layer that lies just above the dense lower atmosphere. In other cases, they look like vertical pillars of light with thin, curling tendrils – and these are called carrot curls due to their resemblance to the root vegetable.

Sprites were given their quasi-magical name by late University of Alaska physics professor Davis Sentman, who devised the name for this weather phenomenon due to it being “well suited to describe their appearance” and fleeting, fairy-like nature – much like the mischievous characters from English folklore.

Sprites occur when lightning strikes the ground, releasing positive electrical energy that requires balancing by an equal and oppositely charged electrical discharge into the sky. The sprites also occur much higher into the sky than regular lightning, which strikes in between electrically charged air, clouds, and our planet’s surface.

In some cases, lightning strikes also send electromagnetic pulses upward, producing glowing disks known as elves.

“On Earth, sprites and elves appear reddish in color due to their interaction with nitrogen in the upper atmosphere,” Giles noted. “But on Jupiter, the upper atmosphere mostly consists of hydrogen, so they would likely appear either blue or pink.”

The Juno team is still unable to confirm whether the events were actually caused by lightning strikes, mainly because the probe’s device that detects lightning is on the opposite side of the spacecraft from its UVS. The images from the two devices are also taken 10 seconds apart, which is far too long a period of time for both instruments to analyze the same flash of light.

However, the researchers are confident that the 11 outbursts detected were transient luminous events. In each case, they disappeared in a flash, emitted massive amounts of hydrogen, and took place 186 miles above Jupiter’s water clouds – far too high to be simple lightning.

“We’re continuing to look for more telltale signs of elves and sprites every time Juno does a science pass,” Giles said.

“Now that we know what we are looking for, it will be easier to find them at Jupiter and on other planets,” she added. “And comparing sprites and elves from Jupiter with those here on Earth will help us better understand electrical activity in planetary atmospheres.”

Dramatic dash cam footage from Pretoria, South Africa, shows the moment that the crew of an armored car narrowly escaped an attempt by armed robes to stage a heist.

The shocking video shows a pair of private security officers transporting cash in a bulletproof Toyota truck on April 22 before they suddenly come under attack by armed assailants.

For the first minute of the roughly three-minute-long video, the security guards can be seen routinely driving down a highway.

The vehicle then comes under fire as bullets can be heard slamming into the driver side of the car, with the window by the driver’s side shattering.

The driver, who maintains his calm and composure during the attack, manages to escape amid the traffic. He also seems to slam into one of the two vehicles belonging to the attackers.

“They’re going to shoot. They’re going to f**king shoot,” the driver then says, urging his colleague to pull out the rifle and prepare to defend their lives.

As gunshots continue to ring out, the two drive silently as the tension builds. The driver then shouts to his colleague: “Phone Robbie, phone Josh! Ask them where they are.”

As the video ends, the driver can be seen stopping the vehicle and grabbing his colleague’s rifle. At that point, it becomes clear that the assailants have realized that their attack was futile they had already fled the scene.

The suspects fired several shots at the [Cash-In-Transit] vehicle in an attempt to stop it during a high-speed chase,” said police spokesperson Brigadier Vishnu Naidoo , reports News24. 

“The driver of the CIT vehicle managed to evade the robbers for a while but later stopped in wait for the robbers,” Naidoo added. “The robbers fled without taking any money. No arrests have yet been made.”

Online users have praised the steel nerves of the armored car’s crew in navigating what could have been a deadly attack.

After Strong Backlash, NYPD Kicks Robotic Dog “Spot” to the Curb

The New York City Police Department decided this week to stop leasing a robotic dog from Boston Dynamics following a sustained outcry from residents and lawmakers, who denounced the use of the high-tech, four-legged device in low-income neighborhoods as a misallocation of public resources and violation of civil liberties.

When the NYPD acquired the K-9 machine last August, officials portrayed “Digidog”—the department’s name for the camera-equipped, 70-pound robot—as “a futuristic tool that could go places that were too dangerous to send officers,” the New York Times reported earlier this week.

Inspector Frank Digiacomo of the department’s Technical Assistance Response Unit said in a television interview in December: “This dog is going to save lives. It’s going to protect people. It’s going to protect officers.”

Instead—thanks to strong backlash from critics, including people who live in the Bronx apartment complex and the Manhattan public housing building where the robotic dog was deployed in recent weeks—the department is returning “Spot,” as Boston Dynamics calls the device, months earlier than expected.

According to the Times:

In response to a subpoena from City Councilman Ben Kallos and Council Speaker Corey Johnson requesting records related to the device, police officials said that a contract worth roughly $94,000 to lease the robotic dog from its maker, Boston Dynamics, had been terminated on April 22.

John Miller, the police department’s deputy commissioner for intelligence and counterterrorism, confirmed on Wednesday that the contract had been canceled and that the dog had been returned to Boston Dynamics or would be soon.

Miller told the Times that the police had initially planned to continue testing the K-9 machine’s capabilities until August, when the lease had been scheduled to end.

The robotic dog came under increased scrutiny in February, after it was deployed in response to a home invasion at a Bronx apartment building, as Common Dreams reported at the time.

“Robotic surveillance ground drones are being deployed for testing on low-income communities of color with under-resourced schools,” Rep. Alexandria Ocasio-Cortez (D-N.Y.) tweeted in response. “Please ask yourself: when was the last time you saw next-generation, world class technology for education, healthcare, housing, etc. consistently prioritized for underserved communities like this?” 

And earlier this month, as Common Dreams reported, footage of the robotic dog walking through a Manhattan public housing building went viral, sparking additional outrage and prompting a city council investigation.

“Why the hell do we need robot police dogs?” Rep. Jamaal Bowman (D-N.Y.) asked at the time. 

While there are “people living in poverty, struggling to put food on the table, keep a roof over their head, take care of their kids, afford child care—all this going on, and now we got damn robot police dogs walking down the street,” Bowman lamented.

Bill Neidhardt, a spokesperson for New York City Mayor Bill de Blasio, who urged the police department to reconsider its use of the robot following objections from residents and lawmakers, said he was “glad the Digidog was put down.”

“It’s creepy, alienating, and sends the wrong message to New Yorkers,” Neidhardt said.

Senate Intelligence Leaders Say Mystery “Sonic Weapon” Attacks on U.S. Officials Increasing

After it was revealed Thursday that US intelligence is investigating at least two potential “directed energy” sonic attacks on White House personnel – one of which is alleged to have happened just off White House grounds – the US Senate Intelligence Committee weighed in on Friday, saying such mysterious incidents appear to be happening with greater frequency worldwide.

Senators Mark Warner (D) and Marco Rubio (R) agreed that such microwave energy attacks have gone on for “nearly five years” and have targeted “US government personnel in Havana, Cuba and elsewhere around the world.” In a joint statement the two ranking members said, “This pattern of attacking our fellow citizens serving our government appears to be increasing. The Senate Intelligence Committee intends to get to the bottom of this,” according to Reuters. 

As with the late 2016 into 2017 ‘Havana Syndrome’ attacks in which some 50 diplomatic personnel reported experiencing strange symptoms from vomiting to concussions to extreme nausea to chronic headaches, which was believed the result of some kind of undetected ‘directed energy’ weapon, the most recent incidents saw media reports speculate that Russia or China might be behind them. 

It was starting last week that the mysterious incidents returned to national media spotlight after defense officials said they believe Russia is likely behind microwave energy weapon attacks on US troops in northeast Syria. Apparently some US troops occupying the country began reporting”flu-like symptoms” which caused the DoD to investigate possible linkage to microwave or directed energy weapons on the battlefield of Syria. Politico reported that “officials identified Russia as a likely culprit, according to two people with direct knowledge of the matter.”

Despite instances of strange symptoms and even head injuries experienced by diplomatic personnel or troops abroad, no “energy weapon” has ever been found or uncovered that’s believed to have caused any of these alleged attacks. Most often US personnel report the symptoms enough time after the alleged attack took place for the “plot” and culprit to remain undetected. Naturally this has resulted in immense skepticism and pushback.

One deeply critical response to all the reporting late this week quipped: “Another day, another mostly anonymously sourced story about unidentified assailants supposedly assaulting U.S. government employees around the globe. This time, according to CNN, federal agencies are looking into something closer to home: symptoms suffered by a White House employee in Virginia and National Security Council staffer near the south lawn of the White House.”

“Although a government report later concluded the most likely cause was instead some sort of ‘directed, pulsed radiofrequency energy’ (i.e. a microwave weapon), that conclusion was primarily based on a lack of evidence for other causes and received strong pushback from many others in the scientific community.”

The commentary in Gizmodo pointed out further that “No hard evidence of any kind for the technology has ever been publicly presented by the US government. Reports citing government officials who suspect Russian intelligence to be involved have largely been anonymous and buoyed primarily by rumors the Russian government may have resumed Soviet-era research into experimental weapons.”
