This episode of the Hubblecast explores the violent world of galactic mergers, as shown by the cosmic duo Arp 142 in a stunning new image from the NASA/ESA Hubble Space Telescope. Galaxies spend most of their life drifting through the cosmic expanse in isolation. But, every so often, two unfortunate galaxies stray a little too close to one another — as is the case with Arp 142. Showcased in a stunning new image from Hubble, these two galaxies uncannily resemble a penguin guarding its egg. The galaxies are in middle of a violent merger, with clouds of gas and dust colliding at breakneck speeds and triggering bursts of star formation.
