Green peas galaxies
WebSep 20, 2024 · Over the years, we have learned these “ (green) pea” galaxies are rare, relatively small (no bigger than 16,300 light-years across compared to our Milky Way‘s 100,000 light-years) with a density about 2/3s less than normal and very high rates of star formation. How do galaxies get their shape? We’re not exactly sure. WebJan 26, 2024 · Green peas are less than 5,000 light-years wide (compared to the Milky Way’s 100,000 light-year span), and they shine a distinctive green due to the light of doubly ionized oxygen, a signature of furious star formation.
