Day 17 of the 2025 Space Telescope Advent Calendar: Distant Starbursts
Day 17 of the 2025 Space Telescope Advent Calendar: Distant Starbursts. Last year, the James Webb Space Telescope made this observation of a dwarf irregular galaxy named I Zwicky 18, some 59 million light-years away from Earth. At the heart of the galaxy are two major star-forming regions surrounded by clouds of gas that have been sculpted by the stellar winds of the hot, young stars.
