☆ How Xs and Cs spotted in the ionosphere could disrupt life on Earth
▼ + stars: | 2024-08-02 | by ( Ashley Strickland | ) edition.cnn.com time to read: +13 min

Earth’s electric and magnetic fields and gravity cause charged particles in the ionosphere to flow away from Earth’s magnetic equator. Typically, plasma bubbles are long and straight because they form along Earth’s magnetic field lines. GOLD observations captured C-shaped and reverse C-shaped plasma bubbles close together in the ionosphere on October 12, 2020, and December 26, 2021. So far, GOLD has only observed two instances of the close pairings, but the C-shaped bubbles have the potential to disrupt communications. “Due to such wide view and continuous measurements, GOLD has allowed us to observe these mysteries within the ionosphere,” Karan said.

☆ NASA’s Curiosity rover makes its ‘most unexpected’ find on Mars
▼ + stars: | 2024-07-20 | by ( Ashley Strickland | ) edition.cnn.com time to read: +10 min

CNN —The Curiosity rover has made its most unusual find to date on Mars: rocks made of pure sulfur. “I think it’s the strangest find of the whole mission and the most unexpected,” said Ashwin Vasavada, Curiosity project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California. Previously, while exploring Mars, NASA’s Spirit rover broke one of its wheels and had to drag it along while using the other five to drive backward. And Vasavada says it’s what inspired the team to “look behind” the Curiosity rover — otherwise they wouldn’t have seen the crushed sulfur. To determine what process formed the sulfur rocks, the team considered nearby bedrock instead.

☆ Mars volcano the size of Mount Everest was hiding in plain sight, report says

CNN —Scientists may have pinpointed a massive, oddly shaped volcano taller than Mount Everest on the surface of Mars — and it has been hiding in plain sight for decades, according to new research. Some of the largest volcanoes on Mars lie relatively close to the proposed “Noctis volcano.” Shown here: 1) Olympus Mons, the tallest known volcano in our solar system. This NASA visualization of the Tharsis rise shows Olympus Mons, Tharsis Montes, Noctis Labyrinthus, and Valles Marineris. NASA SVSA volcano, a glacier and the history of MarsThe existence of a volcano in Noctis Labyrinthus could also help explain the creation of this bizarre landscape. The existence of a volcano in the region, Lee said, might offer more support for the latter theory.
