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.

Wellington, New Zealand AP —United States-born kitefoiler J.J. Rice, who was to represent Tonga at the Paris Olympics, has died in a diving accident. Rice’s father, Darren Rice, confirmed his son’s death Monday to the Matangi Tonga newspaper. Jackson James Rice was set to become the first Caucasian to represent Tonga at an Olympic Games. He was free diving from a boat when he suffered a suspected shallow water blackout, Matangi Tonga reported. “He was an amazing kitefoiler and he would have made it to the Olympics and come out with a big shiny medal.

Instead this year’s ozone hole was about average size for the last 20 years, even a bit smaller than 2022’s, according to NASA and the National Oceanic and Atmospheric Administration. From September to mid October, the ozone hole this year averaged 8.9 million square miles (23.1 million square kilometers), which is the 16th largest since satellites started tracking in 1979. It peaked this year at 10 million square miles (26 million square kilometers), about the size of North America. The ozone hole and thinning ozone layer has improved a bit thanks to the 1987 Montreal Protocol, when countries in the world agreed to stop producing many of the chemicals that deplete ozone, Newman said. The ozone hole was at its biggest in 2000 at nearly 11.6 million square miles (29.9 million square kilometers), according to NASA data.

NEW YORK — When an undersea volcano erupted in Tonga in January, its watery blast was huge and unusual — and scientists are still trying to understand its impacts. “This was a once-in-a-lifetime event,” said lead author Holger Voemel, a scientist at the National Center for Atmospheric Research in Colorado. And since water vapor acts as a heat-trapping greenhouse gas, the eruption will probably raise temperatures instead of lowering them, Toohey said. The water vapor will stick around the upper atmosphere for a few years before making its way into the lower atmosphere, Toohey said. The stratosphere stretches from around 7.5 miles to 31 miles above Earth and is usually very dry, Voemel explained.
