Who is the ‘Doctor Who’ villain Maestro? And what’s their relationship with the Toymaker?

NeRD

There’s a bum note at London’s Abbey Road Studios. The Beatles are recording their 1963 debut LP as planned, but their music is nothing to (twist and) shout about, and they can’t wait to finish the album and get back to Liverpool. It’s not the Fab Four’s fault, however. In “Doctor Who” episode “The Devil’s Chord”, the malevolent Maestro is sucking all the music out of the world, and even the Doctor may be powerless to stop them. (Need a guide on how to watch Doctor Who? Check out our…

NASA’s Mars sample return mission is in trouble. Could a single SLS megarocket be the answer?

NeRD

Boeing has put forward its own idea to help NASA get its Mars Sample Return project back on track and on budget. NASA issued a solicitation for new ideas to get scientifically invaluable Martian material to Earth after being told the current plan is too expensive (about $11 billion), while also being too complex and facing scheduling issues.  Former NASA Chief Scientist Jim Green presented Boeing’s vision for a rejiggered Mars sample return mission concept at the annual Humans to Mars Summit last week.  Related: NASA’s Mars Sample Return in jeopardy…

NASA’s Juno probe captures fascinating high-resolution images of Jupiter’s icy moon Europa

NeRD

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

NeRD

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…

Huge, solar flare-launching sunspot has rotated away from Earth. But will it return?

NeRD

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).  Related: Watch monster flare-spewing sunspot grow to be 15 times wider than Earth (video)…

How do you forecast a solar storm? Space weather experts explain

NeRD

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…

Artemis 2 astronauts simulated a day in the life on their moon mission. Here’s what they learned (exclusive)

NeRD

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…

Satellite images of Rafah illustrate Palestinians fleeing the city

NeRD

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…

Big decision! Curiosity rover keeps following possible Mars river remnant

NeRD

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…
