Astronomers used the James Webb Space Telescope to observe the first asteroid belt seen outside of our solar system and unveiled some cosmic surprises along the way.
The space observatory focused on the warm dust that encircles Fomalhaut, a young, bright star located 25 light-years from Earth in the Piscis Austrinus constellation. The dusty disk around Fomalhaut was initially discovered in 1983 using NASA’s Infrared Astronomical Satellite. But the Webb researchers weren’t expecting to see three nested rings of dust extending out 14 billion miles from the star — or 150 times the distance of Earth from the sun.
“I would describe Fomalhaut as the archetype of debris discs found elsewhere in our galaxy, because it has components similar to those we have in our own planetary system,” said lead study author András Gáspár, assistant research professor of astronomy at the University of Arizona in Tucson, in a statement.
