Ring Galaxy AM 0644 741

The rim of the large blue galaxy at the right is an immense ring-like structure 150,000 light years in diameter composed of newly formed, extremely bright, massive stars. AM 0644-741 is known as a ring galaxy and was caused by an immense galaxy collision. When galaxies collide, they pass through each other and their individual stars rarely come into contact. The large galaxy’s ring-like shape is the result of the gravitational disruption caused by a small intruder galaxy passing through it. When this happens, interstellar gas and dust become compressed, causing a wave of star formation to move out from the impact point like a ripple across the surface of a pond. Other galaxies in the field of view are background galaxies, not interacting with AM 0644-741. Foreground spiky stars are within our own Milky Way. But the smaller intruder galaxy is caught above and right, near the top of the frame taken by the Hubble Space Telescope. Ring galaxy AM 0644-741 lies about 300 million light years away toward the southern constellation Volans. via NASA https://ift.tt/3f3kUvC

Wikipedia article of the day is R. A. B. Mynors. Check it out: Article-Link Summary: R. A. B. Mynors (28 July 1903 – 17 October 1989) was an English classicist and medievalist who held the senior chair of Latin at the universities of Oxford and Cambridge. He served as the Kennedy Professor of Latin at Cambridge from 1944 to 1953 and as the Corpus Christi Professor of Latin at Oxford from 1953 until his retirement in 1970. Mynors had the reputation of one of Britain’s foremost classicists. A textual critic, he specialised in the study of manuscripts and their role in the reconstruction of classical texts. He was an expert on palaeography, and has been credited with unravelling a number of highly complex manuscript relationships. His publications include critical editions of Vergil, Catullus, and Pliny the Younger. In addition to receiving honorary degrees and fellowships from various institutions, Mynors was made a Knight Bachelor in 1963. He died in a car accident, aged 86. His comprehensive commentary on Vergil’s Georgics was published posthumously.
