NASA scientists have combined data from the Spitzer and Hubble telescopes to produce an extraordinary image of two galaxies, collectively known as Arp 142, that looks weirdly like a penguin guarding its egg.
The penguin part, formally known as NGC 2936, the scientists say, was once a bog-standard spiral galaxy. Full of huge crop of newly formed stars – seen here courtesy of Hubble as blue filaments – it seems to have been twisted and deformed by the gravitational pull of its neighbour, NGC 2937, an almost featureless collection of very old stars.
