SPACE: What If Black Holes Aren’t Black – Or Holes?

by
black holes - deposit photos

Black holes, those gravitational monsters so named because no light can escape their clutches, are by far the most mysterious objects in the universe. But a new theory proposes that black holes may not be black at all. According to a new study, these black holes may instead be dark stars home to exotic physics at their core. This mysterious new physics may cause these dark stars to emit a strange type of radiation; that radiation could in turn explain all the mysterious dark matter in the universe, which tugs on everything but emits no light. Dark Stars Thanks to … Read more

SPACE: new Theories on the Mysterious “Planet Nine”

We have not one but two new theories for you about the solar system’s long-theorized and mysterious Planet Nine: Does the solar system have a big, dark ninth planet drifting somewhere far beyond the orbit of Neptune? Planet 9 Probably Doesn’t Exist Since 2016, many astronomers have said it’s possible, pointing to evidence for a large gravity source in deep solar space. But a new paper argues that this gravity source is nothing more than a statistical mirage, the consequence of where in the night sky astronomers point their telescopes. The first physical(CK) hint of this hypothetical Planet Nine was … Read more

SPACE: Proxima Centauri’s Giant Flare Could Be Bad News for Possible Alien Life

Scientists have spotted one of the largest stellar flares ever recorded in our galaxy. The jets of plasma shot outward from the sun’s nearest neighbor, the red dwarf star Proxima Centauri. The flare, which was around 100 times more powerful than any experienced in our solar system, could change the way scientists think about solar radiation and alien life. Proxima Centauri is a red dwarf — the smallest, dimmest and most common type of main sequence stars in the galaxy — located approximately 4.25 light-years from Earth. Its mass is only one-eighth of the sun’s, and it is orbited by … Read more

MARS: NASA Extracts Breathable Oxygen From Thin Martian Air

by
Mars

NASA has logged another extraterrestrial first on its latest mission to Mars: converting carbon dioxide from the Martian atmosphere into pure, breathable oxygen, the U.S. space agency said on Wednesday. The unprecedented extraction of oxygen, literally out of thin air on Mars, was achieved Tuesday by an experimental device aboard Perseverance, a six-wheeled science rover that landed on the Red Planet Feb. 18 after a seven-month journey from Earth. In its first activation, the toaster-sized instrument dubbed MOXIE, short for Mars Oxygen In-Situ Resource Utilization Experiment, produced about 5 grams of oxygen, equivalent to roughly 10 minutes’ worth of breathing … Read more

MARS: Ingenuity Takes Its Maiden Flight

by
Ingenuity

The aerial exploration of Mars has begun. NASA’s Ingenuity helicopter lifted off on the Red Planet early this morning (April 19), performing the first-ever powered flight on a world beyond Earth. The 4-lb. (1.8 kilograms) chopper was scheduled to rise from the floor of Mars’ Jezero Crater at 12:31 a.m. EDT (0431 GMT) today, get a maximum of 10 feet (3 meters) above the red dirt and land after roughly 40 seconds aloft. At about 6:15 a.m. EDT (1015 GMT), data came down from Ingenuity — via its much larger partner, NASA’s Perseverance rover — that the little rotorcraft had … Read more

SPACE: Russia Planning Moon Landing in October

Russia is revisiting its Soviet space heritage for a new series of missions that will take the nation back to the moon. The first of those missions, dubbed Luna 25, is scheduled to launch this October, ending a 45-year drought of Russian moon landings with the nation’s first arrival at the south pole, where, like everyone else targeting the moon, Russian scientists want to study water locked below the surface in permanent ice. “The moon is the center of our program for the next decade,” Lev Zelenyi, scientific advisor for the Russian Space Research Institute, said during a virtual presentation … Read more

SPACE: Mars Odyssey Snaps Beautiful Color-Enhanced Photo of North Pole

NASA astronomers just shared a colorful new view of Mars that proves the Red Planet also looks great in blue. Using a special infrared camera aboard the Mars Odyssey orbiter, which has been soaring over the Red Planet since 2001, researchers snapped a thermal image of the Martian north pole, digitally colored to highlight the wide-ranging temperatures there. Areas tinted in blue represent colder regions, while warmer areas are tinted in yellow and orange, according to a NASA statement. In this image — which covers an area of the pole about 19 miles (30 kilometers) wide — vast sand dunes … Read more

SCIENCE: Spaceflight Shrinks Your Heart

What do extreme long-distance swimming and spaceflight have in common? They can both shrink the heart, according to a new study. Both activities reduce the pressure of gravity on the heart, making it so that it doesn’t have to work as hard to pump blood upwards through the body. The heart is a muscle, and just like any other muscle in the body, if it’s not used as much as it used to be, it will shrink. To understand what effect weightlessness has on the heart, a group of researchers analyzed health data from retired astronaut Scott Kelly’s year aboard … Read more

SPACE: There’s a Green Rock on Mars

Green Rock on Mars - NASA

Perseverance’s laser hasn’t yet penetrated the mystery of a strange Martian rock near the rover’s new digs. NASA’s rover is waiting for its companion, the Ingenuity helicopter, to make the first-ever powered flight on another planet. Meanwhile, its instruments targeted a greenish-looking rock on the Red Planet’s surface that has the science team “trading lots of hypotheses,” according to the rover’s Twitter feed — but please don’t pick aliens as one of them. “Is it something weathered out of the local bedrock?,” a tweet the account posted on Wednesday (March 31) wondered. “Is it a piece of Mars plopped into … Read more

Martian Polar “Spiders” Finally Explained

by
Martian Polar "Spiders - NASA

Ziggy played guitar, and scientists in the U.K. played with a big chunk of dry ice to try to figure out what’s behind the strange alien patterns known as the “spiders on Mars.” Those patterns, visible in satellite images of the Red Planet’s south pole, aren’t real spiders, of course; but the branching, black shapes carved into the Martian surface look creepy enough that researchers dubbed them “araneiforms” (meaning “spider-like”) after discovering the shapes more than two decades ago. Measuring up to 3,300 feet (1 kilometer) across, the gargantuan shapes don’t resemble anything on Earth. But in a new study … Read more
