Galaxy Collision Creates “Space Triangle” in New Hubble Image

The video explores the interaction between spiral galaxy NGC 2445 and its companion NGC 2444. As these galaxies pass through each other, a unique triangular star formation occurs due to the rich gas content in NGC 2445. Despite this, NGC 2445 remains gravitationally bound to NGC 2444, which is pulling gas from it. This cosmic tug of war results in a peculiar triangle of new stars. By studying such galactic collisions, astronomers gain insights into the origins and evolution of ringed star formations and galaxies.

What role does gas play in the star formation process in NGC 2445?

What can studying galaxy collisions like that of NGC 2445 and NGC 2444 help us understand?
