Leaving Pluto in the dust: New Horizons probe gearing up for epic crossing of ‘termination shock’

NeRD

NASA’s New Horizons spacecraft conducted the first and only flyby of the Pluto system, culminating at the closest approach of that distant world in July 2015. Sailing onward, the probe carried out a Jan. 1, 2019 flyby of Arrokoth, a Kuiper Belt Object, or KBO, located in a region of space beyond Neptune called the Kuiper Belt. There are scads of other icy worlds residing in the Kuiper Belt, celestial leftovers from the formation of our solar system. For New Horizons, the gathering of more exploration science is, pun intended,…

Black holes snacking on small stars create particle accelerators that bombard Earth with cosmic rays

NeRD

Using 16 years of data from NASA’s gamma-ray detecting Fermi spacecraft, astronomers have discovered that “microquasars,” systems in which a black hole is slowly devouring a star, may be small, but they pack one heck of a punch. Despite their diminutive nature, this research suggests even microquasars snacking on small stars can have an impressive cosmic influence, becoming powerful natural particle accelerators. This means black holes indulging in stellar meals of all sizes could be responsible for a higher-than-suspected amount of high-energy charged particles called “cosmic rays,” which are constantly…

Lego Marvel Logo & Minifigures set review

NeRD

Essential info: Price: $99.99/£89.99 Model number: 76313 Number of pieces: 931 Dimensions: 4 x 11 x 2.5 inches (11 x 28 x 7cm) Recommend age: 12+ I don’t think any other Lego set has been quite as ‘what you see is what you get’ as the Marvel Logo & Minifigures set. As the name suggests, this literally is a 3D box with the Marvel logo on the front. It’s not exactly inspiring. But it is a solid model, and with some interesting building techniques, it’s fairly fun to build too.…

Boeing plans to lay off hundreds of employees working on NASA’s SLS moon rocket: reports

NeRD

Boeing is preparing to issue layoff notices to roughly 200 employees working on the Space Launch System (SLS) — the massive rocket central to NASA’s flagship Artemis program — as it braces for the possibility that its contracts with the space agency may not be renewed after they end in March. Of the approximately 400 positions Boeing initially considered cutting by April “to align with revisions to the Artemis program and cost expectations,” the company managed to preserve half of the jobs after daily talks with NASA, Boeing’s Vice President…

‘Captain America: Brave New World’ introduces adamantium into the MCU, but did it come from space in the comics?

NeRD

The fourth Captain America movie, Captain America: Brave New World, is finally out and has been met with middling critical reviews. Despite that, fans are already dissecting every new character and plot development that’s transpired as they eagerly await The Fantastic Four: First Steps and Thunderbolts. Most intriguing is the introduction of adamantium in this movie, which is fascinating because of how it differs from the comic book lore. Adamantium is part of the comic book-y, ‘fun first’ science found in the long-running universe. From vibranium to recurring alien threats,…

Japan’s Resilience moon lander aces lunar flyby ahead of historic touchdown try (photo)

NeRD

The private Resilience lunar lander just got its first up-close look at the moon. Resilience, which was built by Japanese company ispace, aced a flyby of the moon on Friday evening (Feb. 14), coming within a mere 5,220 miles (8,400 kilometers) of Earth’s nearest neighbor. The lander memorialized the milestone with a photo, snapping a nice shot of the battered lunar surface from a distance of 8,972 miles (14,439 km). The close encounter was “a historic first of its type for a Japanese private, commercial lunar lander,” according to ispace.…

‘Star Trek: Section 31’ got us thinking… Should you have to do your homework before you watch a movie?

NeRD

Let’s start with a small thought experiment. It’s Saturday night and you spot a new “Star Trek” movie on your Paramount+ homepage. You’re not a hardcore fan but you enjoyed “The Next Generation“, “The Wrath of Khan” and the JJ Abrams reboot. You’re also drawn in by the fact this interstellar version of “Mission: Impossible” is headlined by Michelle Yeoh, who starred alongside James Bond in “Tomorrow Never Dies”, recently appeared in “Wicked”, and won herself an Oscar for “Everything Everywhere All at Once”. That’s got to be worth a…

‘City-killer’ asteroid 2024 YR4 could hit the moon instead of us, scientists say

NeRD

An asteroid that’s big enough to wipe out a city has a 1-in-43 chance of hitting our planet in the year 2032. But according to new calculations, there’s an even smaller chance that it might crash into the moon instead. On Feb. 7, NASA scientists increased the likelihood of asteroid 2024 YR4 colliding with Earth on Dec. 22, 2032, nearly doubling the odds from 1.2% to 2.3%. The potentially hazardous asteroid measures an estimated 180 feet (55 meters) across — about as wide as Walt Disney World’s Cinderella Castle is…

Continent-size blobs in Earth’s mantle are a billion years old, ancient crystals reveal

NeRD

Continent-size islands deep inside Earth’s mantle could be more than a billion years old, a new study finds. Known as large low-seismic-velocity provinces (LLSVPs), these blobs are both hotter and older than nearby areas of the mantle. The findings, published Jan. 22 in the journal Nature, shed light on Earth’s deep interior and could help explain how the mantle moves over time. Scientists have known about these LLSVPs for a few decades. The two giant blobs — one beneath the Pacific Ocean and one beneath Africa — lie at the…

‘Sailing’ satellites of the future could provide early warning of dangerous space weather

NeRD

NEW ORLEANS — Solar sails that allow satellites to glide on the light from the sun could soon become a reality. The technology would allow scientists to provide earlier warnings of space weather events such as geomagnetic storms, which have the potential to disrupt technological systems on Earth. “A lot of us have experienced sailing; it’s exactly like that,” Irfan Azeem, division chief of the Research to Operations and Project Planning Division at National Oceanic and Atmospheric Administration’s (NOAA) Office of Space Weather Observations, told Space.com in an interview here…
