Mars may have made its 2 moons by ripping an asteroid apart

NeRD

Computer simulations suggest that Mars’ puzzling moons, Phobos and Deimos, may have been formed from debris created when a large asteroid wandered dangerously close to the Red Planet. This new model proposes that Phobos and Deimos resulted from the wreckage of a larger asteroid that wandered too close to Mars and crossed its Roche limit — the distance at which gravitational tidal forces emanating from the planet became too great and tore the asteroid apart.  “It’s exciting to explore a new option for the making of Phobos and Deimos —…

Strange ‘zebra’ patterns are coming from the Crab Nebula — this physicist finally figured out why

NeRD

Historical records from around the world describe a bright star appearing in the sky in the year 1054. Today, astronomers are confident that what our ancestors were seeing was, in truth, a star that had gone supernova. But this wasn’t just any supernova. It was a supernova that would eventually lead to the formation of the Crab Nebula — a collage of interstellar gas and dust illuminated by the energy expelled during the death throes of a rapidly contracting nuclear furnace.The star in question would eventually become a pulsar —…

NASA satellites reveal Earth’s continents are getting drier

NeRD

The amount of freshwater found on our planet has dropped significantly in the last decade, NASA satellites have found. An international team of scientists reviewed observations taken by the Gravity Recovery and Climate Experiment (GRACE) satellites operated by NASA, the German Aerospace Center and the German Research Center for Geosciences. The data collected by GRACE revealed that beginning in May 2014, there was a plunge in Earth’s freshwater supply, and the planet has still not recovered. The researchers suggest that this evidence could also mean Earth is undergoing a drier…

The moon eclipses bright blue star Spica this week. Here’s how to see it

NeRD

Earlier this month, the planet Saturn was eclipsed by the moon as seen from Central America, northwest portions of South America, as well as central and southern Florida. This event, known as an occultation (derived from the Latin word occultāre, which means “to conceal”, can be a startling spectacle, especially if it involves a bright star. But unlike a planet which can take up to a minute or two to be completely covered by the moon, a star, in contrast, appears to creep up to the moon’s limb, hangs on…

Best Predator games of all time

NeRD

The Predator movie franchise is now enjoying a resurgence thanks to the big hit that was Prey (2022). With a sequel in the works and another standalone Predator movie coming in the near future, we thought we’d hunt down the best Predator games of all time. Shockingly, the Predator IP hasn’t been nearly as explored as the Alien franchise in video games, at least not on its own; most of the best Predator games ever are actually Alien vs. Predator titles. That doesn’t mean there aren’t ‘solo’ Predator games worth…

NASA tests cellphone-sized underwater robots for future ocean world missions (video)

NeRD

A swarm of tiny robots destined to search for life on a faraway moon recently began its journey in a swimming pool here on Earth. The SWIM robots — short for Sensing With Independent Microswimmers — demonstrated impressive maneuverability during recent tests in the swimming pool at the California Institute of Technology (Caltech). Pushed along by propellers, the miniature, wedge-shaped robots steered themselves to stay on course, executed a back-and-forth “lawnmower” pattern, and even spelled out “J-P-L,” according to a NASA statement.   Designed to one day search for evidence…

How a mini-team of NASA archivists is restoring astronomical history

NeRD

Precious data from space missions, going back decades, is being carefully restored and archived by scientists at NASA’s Space Science Date Coordinated Archive, allowing researchers today to make new discoveries by delving into the history books. “What’s surprising is how much of this information is either lost or at least not in a condition that anybody can use it in,” planetary scientist David Williams of the National Space Science Data Center Archive (NSSDCA) told Space.com. “We’ve got tons of photography, reels of film from various missions, a lot of microfilm…
