"A Galaxy Scores a Bullseye": Irregular Spiral Galaxy NGC 922 in Fornax | Hubble FriendsofNASA.org: NGC 922 is a galaxy that has been hit square-on by another. Ripples of star-formation are still propagating out across thousands of light-years of space over 300 million years after the collision, making it a prime example of what astronomers call a collisional ring galaxy.

Panning across Dwarf Irregular Galaxy I Zwicky 18 | Hubble FriendsofNASA.org | Summary: A companion galaxy can be seen above and to the left of I Zwicky 18. Gravitational interactions between the two galaxies may have triggered I Zwicky 18's recent star formation that is responsible for its youthful appearance. I Zwicky 18 is 59 million light-years from Earth and is located in the Ursa Major constellation. Called I Zwicky 18, this galaxy has a youthful appearance that resembles galaxies typicall

Panning over Starstruck Image of Irregular Galaxy Arp 263 | Hubble FriendsofNASA.org: The irregular galaxy Arp 263 lurks in the background of this image from the NASA/European Space Agency Hubble Space Telescope, but the view is dominated by a stellar photobomber; the bright star BD 17 2217. Arp 263—also known as NGC 3239—is a patchy, irregular galaxy studded with regions of recent star formation, and astronomers believe that its ragged appearance is due to its having formed from the merger of t
