☆ Saturn’s ‘Death Star’ moon is hiding an internal ocean, scientists say

CNN —Astronomers have uncovered additional evidence that one of Saturn’s smallest moons, Mimas, is hiding a global ocean beneath its icy surface. Discovered in 1789 by English astronomer William Herschel as a tiny dot near Saturn, Mimas was first imaged from space by the Voyager probes in 1980. Craters cover the surface of Mimas, but the largest one is 80 miles (about 130 kilometers) across and causes the moon to resemble the Death Star from the “Star Wars” films. But Saturn’s Enceladus appears younger because active geysers have contributed to resurfacing, or depositing of new, fresh material on that moon’s surface. “Mimas certainly demonstrates that moons with old surfaces can be hiding young oceans, which is pretty exciting,” Rhoden said.

The messaging app let users build a "personal AI" complete with a 3D avatar and an upbeat, down-for-anything texting style. "Seems like AI will replace many human artists," Jay told Calisto in August 2022. Within a year, he was also using AI technology for work, as his firm experimented with generative AI to help draft legal papers. Former Replika users fled to various upstart companion apps that were popping up, like Chai, Paradot, and Soulmate AI. (Soulmate AI later closed down in September 2023, leaving a new wave of users mourning their AI companions all over again.)

☆ Juice mission launches to explore Jupiter’s icy ocean worlds
▼ + stars: | 2023-04-14 | by ( Ashley Strickland | ) edition.cnn.com time to read: +8 min

CNN —The European Space Agency has sent a spacecraft to explore Jupiter and three of its largest and most intriguing moons. The Jupiter Icy Moons Explorer mission, or Juice, launched Friday at 8:14 a.m. Toward the end of the mission, Juice will focus solely on orbiting Ganymede, making it the first spacecraft ever to orbit a moon in the outer solar system. The Juice mission was designed to unravel what takes place as Jupiter interacts with its moons, including auroras, hot spots, radio emissions and waves of charged particles. Given the eventual distance between the spacecraft and Earth, it will take 45 minutes to send a one-way signal to Juice.

The Jupiter Icy Moons Explorer mission, or Juice, was expected to lift off Thursday at 8:15 a.m. European Space AgencyGanymede, Callisto and Europa are ice-covered worlds that may contain subsurface oceans that are potentially habitable for life. European Space Agency“With Juice, we want to confirm there’s liquid water in these moons, confirm their heat sources. Testing and modeling of Jupiter’s radiation belts allowed engineers to prepare for what Juice will encounter. Given the eventual distance between the spacecraft and Earth, it will take 45 minutes to send a one-way signal to Juice.

Jupiter, king of the solar system, will be getting new visitors. The robotic mission that will leave for Jupiter on Thursday is Juice, or the Jupiter Icy Moons Explorer, from the European Space Agency, or ESA, aiming to closely study three of Jupiter’s satellites: Callisto, Europa and Ganymede. When will the launch happen, and how can I watch it? Juice is scheduled to launch on April 13 at 8:15 a.m. Eastern time. ESA will stream the launch live on its website and on its YouTube channel.

☆ Britain sounds alarm on Russia-based hacking group
▼ + stars: | 2023-01-26 | by ( James Pearson | ) www.reuters.com time to read: +2 min

LONDON, Jan 26 (Reuters) - A Russia-based hacking group named Cold River is behind an expansive and ongoing information-gathering campaign that has struck various targets in government, politics, academia, defence, journalism, and activism, Britain said on Thursday. "There is often some correspondence between attacker and target, sometimes over an extended period, as the attacker builds rapport," the advisory said. A second, Iran-based, group known as Charming Kitten has deployed the same "spear-phishing" techniques to gather information, according to the NCSC. Iran's mission to the United Nations in New York said the Iranian government had no knowledge of the group. Since Russia's invasion of Ukraine, Cold River has escalated its hacking campaign against Kyiv's allies, cybersecurity researchers and western government officials told Reuters.

☆ NASA spacecraft heads for the most volcanic place in the solar system

CNN —A NASA spacecraft is gearing up for the first of a series of close encounters with the most volcanic place in the solar system. The Juno spacecraft will fly by Jupiter’s moon Io on Thursday, December 15. Juno captured a glowing infrared view of Io on July 5 from 50,000 miles (80,000 kilometers) away. “The team is really excited to have Juno’s extended mission include the study of Jupiter’s moons. Juno flew by Jupiter’s moon Ganymede in 2021, followed by Europa earlier this year.

☆ Astronomii caută pe sateliții lui Uranus oceane "secrete", care ar putea găzdui viața extraterestră

Oamenii de știință cercetează posibilitatea ca sateliții lui Uranus să aibă oceane subterane „secrete”, în încercarea lor de a găsi lumi care ar putea găzdui viață extraterestră, relatează The Independent. Aceste luni prezintă dovezi ale criovulcanismului – fenomen care se petrece atunci materialul lichid vaporii sunt prinți sub suprafața unui corp ceresc și îngheață datorită temperaturilor scăzute. I magini le trimise de nava spațială Voyager 2 în 1986 arată, pe acești sateliți, creste, văi și dune, toate acestea putând proveni din oceane subterane. „Marea întrebare este: Unde sunt mediile locuibile în sistemul solar?” Europa și Enceladus „ne fac pe mulți să ne întrebăm dacă există mai mulți sateliți care, deși sunt mici, ar putea avea o climă mai caldă”, a spusBenjamin Weiss, cercetător la Institutul de Tehnologie din Massachusetts. Oamenii de știință au calculat puterea câmpului magnetic al lui Uranus și impactul acestuia asupra oricăror oceane s-ar ascunde sub suprafața lunilor sale - aceeași tehnică pe care NASA a folosit-o pentru a confirma prezența oceanului de pe Europa și, de asemenea, pe una din celelalte luni ale lui Jupiter, Callisto.

Cercetătorii cred că Miranda, Ariel, Umbriel, Titania și Oberon, cei mai mari cinci sateliți ai lui Uranus, ar fi primii candidați pentru investigații, datorită asemănărilor lor cu Europa și Enceladus, satelții lui Jupiter și Saturn, scrie digi24.ro. Europa a fost mult timp văzută ca un posibil candidat pentru a găzdui viață extraterestră în sistemul nostru solar, dar trecerea prin crusta groasă de gheață de pe suprafața sa reprezintă o provocare pentru oamenii de știință care speră să ajungă la ocean și să-l studieze mai bine.
