Hubblecast 67: Of galaxies and penguins — Arp 142
The ESA astronomy podcast, bringing you the latest from the Hubble Space Telescope
20 June 2013
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.
