Last year, researchers from the Carnegie Institution for Science announced they had discovered 12 new moons in orbit around Jupiter. Jupiter is blessed with an abundance of moons, and these new discoveries brought the total number to 79. In order to name these newly-discovered bodies, Carnegie Science turned to the public for suggestions, and now it has announced the new names for five of the moons.

There will be no naming the moons Moony McMoonface, however. Astronomers have a strict naming scheme when it comes to Jupiter’s moons that the researchers wanted to respect.

“There are many rules when it comes to how we name moons,” Carnegie’s Scott Sheppard, leader of the team who discovered the new moons, explained in a statement. “Most notably, Jovian naming conventions require its many moons to be named after characters from Greek and Roman mythology who were either descendants or consorts of Zeus or Jupiter.”

The names were gathered from suggestions on Twitter under the hashtag #NameJupitersMoons and were passed on to the International Astronomical Union for approval. The approved names are as follows:

S/2017 J4 is now Pandia, daughter of Zeus and the Moon goddess Selene. She is the goddess of the full moon, making her the ideal choice for naming a lunar body.

S/2018 J1 is now Ersa, appropriately enough the sister of Pandia and the goddess of dew.

S/2003 J5 is now Eirene, daughter of Zeus and Themis and the goddess of peace.

S/2003 J15 is now Philophrosyne, granddaughter of Zeus and sister of Eupheme, who is the spirit of welcome and kindness.

S/2003 J3 is now Eupheme, granddaughter of Zeus and sister of Philophrosyne, who is the spirit of praise and good omen.

Overall, the researchers are delighted with the creativity and engagement of the public in this naming process, and happy with the final names that were chosen. “I was blown away by the enthusiastic response for this contest,” Sheppard said. “I hope the thought of these moons let everyone ponder the wonder and amazement that is our universe.”

There's a scene in Mission Impossible 3 that you might recall. In it, our hero Ethan Hunt (Tom Cruise) tackles the movie's villain, holds him at gunpoint, and forces him to read a bizarre series of sentences aloud.

"The pleasure of Busby's company is what I most enjoy," he reluctantly reads. "He put a tack on Miss Yancy's chair, and she called him a horrible boy. At the end of the month, he was flinging two kittens across the width of the room ..."

Digital Trends’ Top Tech of CES 2023 Awards

Best of CES 2023 Awards Our Top Tech from the Show Feature

Let there be no doubt: CES isn’t just alive in 2023; it’s thriving. Take one glance at the taxi gridlock outside the Las Vegas Convention Center and it’s evident that two quiet COVID years didn’t kill the world’s desire for an overcrowded in-person tech extravaganza -- they just built up a ravenous demand.

From VR to AI, eVTOLs and QD-OLED, the acronyms were flying and fresh technologies populated every corner of the show floor, and even the parking lot. So naturally, we poked, prodded, and tried on everything we could. They weren’t all revolutionary. But they didn’t have to be. We’ve watched enough waves of “game-changing” technologies that never quite arrive to know that sometimes it’s the little tweaks that really count.

Digital Trends’ Tech For Change CES 2023 Awards

Digital Trends CES 2023 Tech For Change Award Winners Feature

CES is more than just a neon-drenched show-and-tell session for the world’s biggest tech manufacturers. More and more, it’s also a place where companies showcase innovations that could truly make the world a better place — and at CES 2023, this type of tech was on full display. We saw everything from accessibility-minded PS5 controllers to pedal-powered smart desks. But of all the amazing innovations on display this year, these three impressed us the most:

Samsung's Relumino Mode
Across the globe, roughly 300 million people suffer from moderate to severe vision loss, and generally speaking, most TVs don’t take that into account. So in an effort to make television more accessible and enjoyable for those millions of people suffering from impaired vision, Samsung is adding a new picture mode to many of its new TVs.

Relumino Mode, as it’s called, works by adding a bunch of different visual filters to the picture simultaneously. Outlines of people and objects on screen are highlighted, the contrast and brightness of the overall picture are cranked up, and extra sharpness is applied to everything. The resulting video would likely look strange to people with normal vision, but for folks with low vision, it should look clearer and closer to "normal" than it otherwise would.
Excitingly, since Relumino Mode is ultimately just a clever software trick, this technology could theoretically be pushed out via a software update and installed on millions of existing Samsung TVs -- not just new and recently purchased ones.
