Astronomers using the James Webb Space Telescope (JWST) have taken a fresh look at the distant edges of our solar system — and found that, once again, Pluto is defying expectations.
When NASA's New Horizons spacecraft flew past Pluto in 2015, it shattered the notion that the dwarf planet was a dormant ball of ice, instead revealing it to be rich with icy plains and jagged mountains. But one of the biggest surprises floated above it all: a bluish, multi-layered haze blanketing the world's sky, stretching more than 185 miles (300 kilometers) above the surface — far higher and more intricate than scientists had predicted.
