- NASA is Developing Solutions for Lunar Housekeeping’s Biggest Problem: Dust!by Matt Williams on December 22, 2024 at 1:22 am
Through the Artemis Program, NASA will send the first astronauts to the Moon since the Apollo Era before 2030. They will be joined by multiple space agencies, like the ESA and China, who plan to send astronauts (and “taikonauts”) there for the first time. Beyond this, all plan to build permanent habitats in the South … Continue reading "NASA is Developing Solutions for Lunar Housekeeping’s Biggest Problem: Dust!"

- Where’s the Most Promising Place to Find Martian Life?by Paul M. Sutter on December 22, 2024 at 12:32 am
New research suggests that our best hopes for finding existing life on Mars isn’t on the surface, but buried deep within the crust. Several years ago NASA’s Curiosity rover measured traces of methane in the Martian atmosphere at levels several times the background. But a few months later, the methane disappeared, only for it to … Continue reading "Where’s the Most Promising Place to Find Martian Life?"

- Can Entangled Particles Communicate Faster than Light?by Paul M. Sutter on December 21, 2024 at 12:29 am
Entanglement is perhaps one of the most confusing aspects of quantum mechanics. On its surface, entanglement allows particles to communicate over vast distances instantly, apparently violating the speed of light. But while entangled particles are connected, they don’t necessarily share information between them. In quantum mechanics, a particle isn’t really a particle. Instead of being … Continue reading "Can Entangled Particles Communicate Faster than Light?" The post Can Entangled Particles Communicate Faster than Light? appeared first on Universe Today.

Stardate Podcast: The winter solstice is the shortest day of the year – the shortest gap between sunrise and sunset. After the solstice, the days gradually get longer, all the way until summer solstice, in June. But the weather doesn’t begin to warm up right after the solstice. On average, in fact, the coldest […] Winter will spring on the northern hemisphere in the wee hours of tomorrow morning – the winter solstice. That makes today and tomorrow the shortest days of the year – the shortest interval from sunrise to sunset. That makes the nights the longest of the year.
Over the centuries, many cultures […] Space agencies have been sending missions to the Moon for more than six decades. More than a hundred of them have succeeded. And each success has told us a little bit more about our satellite world.
One of the more recent lessons came from a Chinese mission. Chang’e 5 landed in the Ocean of […] If you were camping on Mars right now, you’d see a couple of bright lights low in the west at nightfall. The brighter and higher of the two is Venus. Just as it does for those of us on Earth, it shines as Mars’s brilliant Evening Star. It’s the brightest object in the planet’s night sky […] It’s generally a good idea to make sure your potatoes are dirt-free before you dig in. If you’re on Mars or the Moon, though, it might be good to mix them with dirt. The combination might make an especially strong form of concrete.
Scientists and engineers have spent years thinking about ways […]
