A volcanic eruption thousands of miles away could be making sunrises and sunsets more colorful, researchers say. A team at University of Colorado Boulder sent up a high-altitude balloon to collect samples of particles in the Earth's stratosphere.
A team at the school noticed that over the summer, sunrises and sunsets have had more of a purple color to them. They sent up a high-altitude balloon to collect samples of particles in the Earth's stratosphere, according to a news release from the school last week."These particles, or aerosols, scatter sunlight as it passes through the air, which in combination with the absorption of light by the ozone layer, gives sunrises and sunsets that purple tint," the release says.
This blue light mixes with the red light already coming from the sun, giving a the sky a purple color.Lars Kalnajs, a research associate in the Laboratory for Atmospheric and Space Physics at the school, led the project and said this eruption is no cause for concern, but warns that we need to prepare for a bigger one.Why a volcanic eruption caused a 'year without a summer' in 1816 "A really big eruption would have a major impact on humanity," Kalnajs said in the news release.
