The #Hubble #Arp #Galaxy Survey: https://iopscience.iop.org/article/10.3847/1538-4365/adfc67 -> "We present new optical F606W images and point-source photometry for 216 systems, whose sizes are well matched to the Advanced Camera for Surveys’ wide field of view. Essentially, none of the samples had been previously observed with Hubble. The resulting images display rich morphologies, revealing a variety of massive stars, H ii regions, stellar clusters, dust lanes, tidal tails, backlit galaxies, and occasional chance superpositions" -> interview with the first author: https://www.youtube.com/watch?v=eewSudl4w34

The Hubble space telescope turned 36 recently, and requested Earth send up some ibuprofen and a foot massager.
