Space Hurricane Seen Above Magnetic North Pole Was Raining Electrons
The first space hurricane ever was spotted in August 2014, consisting of “an eddy of plasma, a type of superhot, charged gas found throughout the solar system,” reports Business Insider. “And instead of rain, this storm brought showers of electrons.” From the report: In August 2014, satellites observed a swirling mass with a quiet center more than 125 miles above the…
NASA selects 16 futuristic space technology concepts

Lab-grown black hole behaves just like Stephen Hawking said it would
Like mad scientists, researchers are creating miniature black holes in their laboratories. Their mission? To see if a mysterious form of radiation predicted by Stephen Hawking exists. Source: https://www.livescience.com/black-hole-analog-confirms-hawking.html
The distance to the North Polar Spur
One of the largest structures in the Milky Way galaxy, the North Polar Spur, was discovered at radio and X-ray wavelengths. The Spur is a giant ridge of bright emission that rises roughly perpendicularly out of the plane of the galaxy starting roughly in the constellation of Sagittarius and then curves upward, stretching across the sky for over thirty degrees (the…
What is a quasar?
A quasar is an extremely bright and distant point-like source visible to radio telescopes. The source is a so-called Active Galactic Nucleus, fueled by a supermassive black hole. Source: https://earthsky.org/astronomy-essentials/definition-what-is-a-quasar…
The Perseverance Rover CPU Has Similar Specs To a Clamshell Ibook From 2001
An anonymous reader writes: NASA’s Perseverence rover, which is currently exploring Mars, has as it’s CPU a BAE Systems RAD 750 running at a 200 Mhz and featuring 256 Megabytes of RAM with 2 Gigabytes of storage. This is a radiation hardened version of the PowerPC G3, with specs roughly equivalent to the Clamshell Ibook that Reese Witherspoon used in Legally…
