Starburst galaxies are galaxies that are undergoing incredibly high rates of star formation. NGC 1569 is one such galaxy — forming stars roughly 100 times faster than our own Milky Way Galaxy for the past 100 million years or so. https://t.co/Hb9nyecYaf 17.7K views · 540 likes · 116 reposts · 6 replies 27 Aug 2026 · Open on X →
Take in this new image of the barred spiral galaxy NGC 1672 from Chandra, @NASAHubble, and @NASAWebb. Studying barred spirals in action can help reveal how gas in our own Milky Way, which is also a barred spiral, feeds its central black hole and forms new stars.🌀 https://t.co/ONV 60.6K views · 767 likes · 158 reposts · 10 replies 25 Aug 2026 · Open on X →
