Or perhaps you'll be sitting in an aircraft, looking out the window at its shadow, and see a circle of light, like a halo below (known as glories). Or, if you're really adventurous, maybe you'll even be out on a midnight walk with a full moon lighting your way, and see what appears to be a rainbow encircling the moon. /news/2025-08-sun-dogs-rainbows-glories-celestial.html Planetary Sciences Thu, 28 Aug 2025 15:28:03 EDT news675613681 Sea spray aerosol research highlights fundamental differences between shorelines and open oceans About 71% of Earth's surface is covered by the vast oceans. When winds blow over the sea surface, they transfer energy to the water, creating waves. Some of these waves, under the force of strong winds, break and produce tiny airborne droplets that become sea spray aerosols. This process happens across all oceans and is one of the world's largest sources of aerosols. Despite decades of research, scientists still do not fully understand the impact on the planet's climate, especially how much they contribute to particles that form clouds, known as cloud condensation nuclei. /news/2025-08-sea-spray-aerosol-highlights-fundamental.html Earth Sciences Environment Thu, 28 Aug 2025 15:02:04 EDT news675612121 Tijuana River's toxic water pollutes the air: Study shows hydrogen sulfide levels exceed air quality standards For decades, the Tijuana River has carried millions of gallons of untreated sewage and industrial waste across the U.S.-Mexico border.
