Slow motion of a spiral magnet.🔥

Since the forces that generate our magnetic field are constantly changing, the field itself is also in continual flux, its strength waxing and waning over time. This causes the location of Earth's magnetic north and south poles to gradually shift, and to even completely flip locations every 300,000 years or so.

A nova explosion is predicted to happen anytime between now and September 2024, which will look like a brand new star in the sky!☄️

Published March 15, 2024, 4:03 p.m. ET. Call it the Skytanic. Engineers have unveiled plans for the world's largest airplane, dubbed the WindRunner, which could revolutionize renewable energy by transporting gigantic wind turbine blades from point A to B.

Space doesn't have a smell in the traditional sense because it's a vacuum with no air to carry odors. However, astronauts returning from spacewalks have reported a distinct odor on their suits and equipment. This smell is often described as being similar to burnt or fried food, hot metal, or welding fumes. The source of this smell is believed to be from polycyclic aromatic hydrocarbons (PAHs), which are a byproduct of the incomplete combustion of organic material. These PAHs can be found throughout the universe and are thought to originate from stars and interstellar dust. When astronauts return from the vacuum of space and re-enter the airlock spacecraft, these molecules can cling to their suits and equipment. Once back in the oxygen-rich environment of the spacecraft, these molecules can oxidize, releasing the distinctive burnt smell. Additionally, the high-energy particles and vacuum of space can lead to the breakdown of materials on the spacecraft, spacesuits, and other equipment, contributing to the unique smell experienced by astronauts.

GPS satellite team work! Part of this was working towards getting GPS on the moon! Here’s the technical stuff🛰

Near-Earth asteroid Bennu is a rubble pile of rocks and boulders left over from the formation of the solar system. On October 20, 2020, NASA’s OSIRIS-REx spacecraft briefly touched down on Bennu and collected a sample for return to Earth. During this “TAG event,” the spacecraft’s arm sank far deeper into the asteroid than expected, confirming that Bennu’s surface is incredibly weak. Now, scientists have used data from OSIRIS-REx to revisit the TAG event and better understand how Bennu’s loose upper layers are held together.

The asteroid Bennu keeps bringing us new science! Astronomers think it might be a piece of an ancient ocean world! ☄️

With an average surface temperature around -81 F (-63 C), Mars has a lower speed of sound, around 540 mph (~240 meters per second), compared to about 760 mph (~340 meters per second) on Earth. You probably wouldn't notice up close, but over longer distances you might.🔊
