When NASA’s Juno spacecraft performed its closest approach to Jupiter‘s moon Europa in September 2022, it captured evidence not only for pockets of briny water connected to the world’s deep subsurface ocean, but also for potential scars formed by towering plumes of water vapor — and it caught that evidence on camera The majority of imagery from the Juno mission is taken by an instrument called JunoCam, which scientists revealed was able to take four high-resolution images of Europa’s surface as it raced past the icy moon at an altitude…

Dusty galaxy looks like a cosmic net in gorgeous new Hubble Telescope photo
A new Hubble image highlights the intricacies of a distant galaxy glowing with a bright white core surrounded by complex dust structures. A new image from the Hubble Space Telescope captures the sharpest view yet of the lenticular galaxy NGC 4753. The photo, released on Monday (May 13), offers a nearly edge-on view of the galaxy, revealing its bright central bulge. Lenticular galaxies are a cross between spirals and ellipticals; they exhibit an elliptical shape but have ill-defined spiral arms. Given NGC 4753’s low-density environment and complex structure, this particular…
Read MoreHuge, solar flare-launching sunspot has rotated away from Earth. But will it return?
Talk about a dramatic exit! The sunspot AR3664, which is about 15 times wider than Earth, has finally rotated out of our planet’s view — but not before firing off two more big solar storms. The most recent solar flares from AR3664 were in the X class, the strongest category — an X3.4 monster that peaked today (May 15) at 4:37 a.m. EDT (0837 UTC) and an X2.9 that followed at 10:38 a.m. EDT (1438 GMT).

Read MoreHow do you forecast a solar storm? Space weather experts explain
For those who had the opportunity to see the aurora this weekend, it was quite a spectacular moment. But while seeing the aurora borealis is thrilling and exciting for us, the same coronal mass ejections (CMEs) and geomagnetic storms that make these light shows possible can also wreak havoc on some of the technology that’s part of our daily lives. There was a lot of buzz last weekend about other possible impacts when the historic geomagnetic storms reached the extreme G5 category. Companies that operate satellites like SpaceX reported on…
Read MoreArtemis 2 astronauts simulated a day in the life on their moon mission. Here’s what they learned (exclusive)
Ever have one of those nightmares where you forget your pencil, or some key item, before a big test? Astronauts flying to the moon face that situation in spades: Once everything is on the spacecraft and they’re on the way, there’s no way to add to or change anything on the Orion spacecraft. So the Artemis 2 crew practiced a “day in the life” of their moon mission, expected to fly there in 2025, to see if there were any little items they may have forgotten. The astronaut quartet literally…
Read MoreSatellite images of Rafah illustrate Palestinians fleeing the city
Satellite images taken earlier this month offer a spaceborne perspective of the ongoing Israel-Hamas war. They include scenes such as a before-and-after sequence that illustrates Palestinian civilians fleeing Rafah, a view of damaged buildings in the region and conglomerates of Israeli hardware. For the past several months, Israeli Defense Forces (IDF) have destroyed major portions of areas in which Palestinian civilians live as a response to the Oct. 7 terrorist attack in Israel, an attack orchestrated by the radical militant group Hamas. As Reuters reported on May 14, Israel says…
Read MoreBig decision! Curiosity rover keeps following possible Mars river remnant
For the past month, NASA’s Curiosity rover has been shadowing Gediz Vallis, a channel that scientists think may be the fossil of an ancient Martian river. Last week, Curiosity reached the north side of Pinnacle Ridge, part of a rock wall that looms over Gediz Vallis. In fact, after Curiosity navigated bumpy ground to do that, it found that the ridge’s south side is navigable. That left Curiosity’s overseers at NASA’s Jet Propulsion Laboratory (JPL) in Southern California with a choice: Should they keep on their planned course, continuing to…
Read MoreThis time, we take it from no one: Why opening the High Frontier of space can be different (op-ed)
As we move closer to the greatest revolution of all time, the opening of the High Frontier of space to humanity, some assert this is somehow a bad thing. Based on inaccurate understandings of history and misplaced projections of those misunderstood times to the future, they are spreading ridiculous and possibly dangerous ideas that what is happening in what I call the Space Revolution is a repeat of the conquests and colonization of history. Wrong. Aside from the fact that we are not taking space from anyone, this time, for…
Read More‘Kingdom of the Planet of the Apes’ reinvigorates an aging ‘Apes’ franchise (review)
One of the most underappreciated and longest-running franchises in Hollywood history is “Planet of the Apes,” that imaginative science fiction property which began with the Charlton Heston-led classic from 1968 directed by Franklin J. Schaffner. Adapted from the 1963 French novel by Pierre Boulle, the plotline centered around astronauts crash landing on a planet in the far future where intelligent simians rule the world and humans are mute feral creatures subjected to all kinds of cruelties. The twist ending of course is that this is no remote alien world,…
Read MoreSpaceX Starship’s next launch ‘probably 3 to 5 weeks’ away, Elon Musk says
We’re likely still a month or so away from the next launch of SpaceX’s Starship megarocket. That was the timeline Elon Musk offered in a post on X over the weekend, saying Starship’s next test flight is “probably 3 to 5 weeks” away. “Objective is for the ship to get past max heating, or at least further than last time,” the billionaire entrepreneur added. The 400-foot-tall (122 meters) Starship is the biggest and most powerful rocket ever built. It consists of two elements, both of which are designed to be…
