Our #HubbleTopImage features a galactic bullseye! 🎯⁠ ⁠ Bright pink nebulae almost completely encircle a spiral galaxy in this NASA/ESA Hubble Space Telescope image of NGC 922. The ring structure and the galaxy’s distorted spiral shape result from a smaller galaxy scoring a cosmic bullseye, hitting the centre of NGC 922 some 330 million years ago.⁠ ⁠ As the small galaxy passed through, it caused ripples that disrupted the clouds of gas, triggering the formation of new stars whose radiation then lit up the remaining gas. The bright pink colour of the resulting nebulae is a characteristic sign of this process!⁠ ⁠ For more information check the link in bio.⁠ ⁠ 📷 NASA, ESA⁠ ⁠ #ESA #Hubble
