NASA captures 'Penguin and the Egg' galaxies in slow collision
NASA has released new images of Arp 142, a rare interacting galaxy pair nicknamed the 'Penguin and the Egg', captured during an active gravitational encounter. The penguin, a spiral galaxy, is being strongly distorted by its neighbour's gravity, with stretched arms and gas streams. The egg galaxy appears smooth and nearly featureless, dominated by older stars.
