We know the sun belches out solar winds, but the origin of these streams of charged particles remain a mystery and has been the subject of numerous studies over the past decades. The images captured last year by the Extreme Ultraviolet Imager (EUI) instrument aboard ESA’s and NASA’s Solar Orbiter, however, may have finally given us the knowledge needed to explain what powers these winds. In a paper published in Science, a team of researchers described observing large numbers of jets coming out of a dark region of the sun called a “coronal hole” in the images taken by the spacecraft. 

The team called them “picoflare jets,” because they contain around one-trillionth the energy of what the largest solar flares can generate. These picoflare jets measure a few hundred kilometers in length, reach speeds of around 100 kilometers per second and only last between 20 and 100 seconds. Still, the researchers believe they have the power to emit enough high-temperature plasma to be considered a substantial source of our system’s solar winds. While Coronal holes have long been known as source regions for the phenomenon, scientists are still trying to figure out the mechanism of how plasma streams emerge from them exactly. This discovery could finally be the answer they’d been seeking for years. 

Lakshmi Pradeep Chitta, the study’s primary author from the Max Planck Institute for Solar System Research, told Space: “The picoflare jets that we observed are the smallest, and energetically the weakest, type of jets in the solar corona that were not observed before…Still, the energy content of a single picoflare jet that lives for about 1 minute is equal to the average power consumed by about 10,000 households in the UK over an entire year.”

Chitta’s team will continue monitoring coronal holes and other potential sources of solar winds using the Solar Orbiter going forward. In addition to gathering data that may finally give us answers about the plasma flows responsible for producing auroras here on our planet, their observations could also shed light on why the sun’s corona or atmosphere is much, much hotter than its surface.

In movies, a hacker typically sits at a large desk with a slew of cutting-edge technology in front of them. In real life, it turns out all you need is an Amazon Fire TV stick, smartphone, keyboard and mouse to steal and leak clips from a game like the hotly anticipated yet to be released Grand Theft Auto IV. That’s exactly what Arion Kurtaj, a member of hacking group Lapsus$, did while already on bail for allegedly hacking NVIDIA, the BBC reports. The 18-year-old infiltrated Rockstar Games, which created GTA VI, going so far as to announce himself as an “attacker” in the company’s slack channel. The scene of the crime? A UK Travelodge hotel officials had placed him in.

Kurtaj was moved to the hotel after hackers “doxxed” him, releasing detailed information about him and his family online, and compromising his safety. While there he was allowed no internet access — something he used the Fire TV Stick to get around. 

Further details of Kurtaj’s illegal stunt became public following a seven-week trial and his being found guilty of hacking Rockstar, neobank Revolut and Uber. A 17-year-old was also convicted but, unlike Kurtaj, is still out on bail. The two individuals are autistic, and psychiatrists deemed them ineligible to stand trial. This meant that the jury only weighed in on if they believed the crimes were committed, not if they were done with criminal intent.

Lapsus$, referred to in court as a group of “digital bandits,” is believed to be comprised mostly of teenagers from Brazil and the UK — Kurtaj and the unnamed 17-year-old are two of seven members arrested in the UK. Between 2021 and 2022, Lapsus$ also allegedly hacked Samsung, T-Mobile and Microsoft. Though the group requested ransoms, it’s unclear how much it made from these exploits, if much at all.

The PSP is back! Sort of. This week, Sony announced the PlayStation Portal, a $200 handheld that can only stream games from your PS5. In this episode, Devindra and Producer Ben Ellman try to figure out what the heck Sony is doing. Is the Portal something gamers actually want? Or did Sony completely miss an opportunity to build a better portable? Also, we discuss why we’re excited for Armored Core VI and some serious big mecha action.
