Scientists at the University of Utah explored the potential of using the lunar particles to shield sunlight before it reaches our planet.
For decades, researchers have considered using screens, objects or dust particles to block just enough of the sun’s radiation – between 1% and 2% – to mitigate the effects of global warming, a journal published Wednesday in PLOS Climate stated. Now, they have analyzed different properties of dust particles, quantities of dust and the orbits that would be best suited for shading Earth.
Ben Bromley, professor of physics and astronomy and lead author of the study, joined a team of astronomers who applied a technique to study planet formation around distant stars.
Planet formation is a “messy process that kicks up lots of astronomical dust that can form rings around the host star,” the journal stated.
“These rings intercept light from the central star and re-radiate it in a way that we can detect it on Earth,” the journal added. “One way to discover stars that are forming new planets is to look for these dusty rings.”
That was the seed of the idea, according to Bromley.
