Picture of the Day - The Tinker Bell Triplet

Using ESO’s Very Large Telescope, an international team of astronomers has discovered a stunning rare case of a triple merger of galaxies. This system, which astronomers have dubbed ‘The Bird’ – albeit it also bears resemblance with a cosmic Tinker Bell – is composed of two massive spiral galaxies and a third irregular galaxy.

In this image, a 30-min VLT/NACO K-band exposure has been combined with archive HST/ACS B and I-band images to produce a three-colour image of the ‘Bird’ interacting galaxy system. The NACO image has allowed astronomers to not only see the two previously known galaxies, but to identify a third, clearly separate component, an irregular, yet fairly massive galaxy that seems to form stars at a frantic rate. The final colour image was produced by Henri Boffin (ESO).
