Northern Lights Alert: Best Viewing Spots in the U.S. Tonight

The northern U.S. may witness the aurora borealis on Saturday night, with states like Michigan, Wisconsin, and Washington having a chance to see the northern lights due to a Kp index of three, as forecasted by NOAA. This auroral activity is expected to continue through Monday, with potential disruptions to radio communications and power grids due to solar radiation. The best viewing times are between 10 p.m. and 2 a.m. local time, away from light pollution. The increased visibility of the northern lights is linked to recent solar activity and a recent supermoon event.

"Reflective 'Cooling Glass' May Combat Climate Change by Bouncing Back Solar Rays"

Scientists have developed a "cooling glass" coating capable of reflecting 99 percent of solar radiation back into space, potentially helping to combat climate change by cooling the Earth. This durable, ceramic-based paint can withstand extreme temperatures and exposure to various elements, offering a long-lasting solution with a lifespan of at least 30 years. The technology leverages the atmospheric transparency window to release heat into space without warming the atmosphere, which could reduce reliance on air conditioning and contribute to global cooling efforts. The research has been published in the journal Science.
