Markarian s Chain

Near the heart of the Virgo Galaxy Cluster the string of galaxies known as Markarian’s Chain stretches across this deep telescopic field of view. Anchored in the frame at bottom center by prominent lenticular galaxies, M84 (bottom) and M86, you can follow the chain up and to the right. Near center you’ll spot the pair of interacting galaxies NGC 4438 and NGC 4435, known to some as Markarian’s Eyes. Its center an estimated 50 million light-years distant, the Virgo Cluster itself is the nearest galaxy cluster. With up to about 2,000 member galaxies, it has a noticeable gravitational influence on our own Local Group of Galaxies. Within the Virgo Cluster at least seven galaxies in Markarian’s Chain appear to move coherently, although others may appear to be part of the chain by chance. via NASA https://ift.tt/3bM7zGm

Wikipedia article of the day is Opening of the Liverpool and Manchester Railway. Check it out: Article-Link Summary: The opening of the Liverpool and Manchester Railway (L&M), often considered the dawn of modern transport, took place on 15Β SeptemberΒ 1830. Eight trains set out from Liverpool to Manchester carrying dignitaries including the Duke of Wellington, then prime minister. At Parkside the trains stopped to take on water, and former cabinet minister William Huskisson alighted and was struck by a locomotive, suffering fatal injuries. As a large crowd waiting to meet the trains in Manchester was becoming unruly, Wellington decided that the event should continue. On arrival in Manchester a hostile crowd pelted Wellington with vegetables and he ordered the trains return to Liverpool. Faults meant only three of the locomotives were still functional; the party eventually returned six and a half hours late. The accidents led to significant coverage of the opening, raising the profile of the new technology, and within a month schemes were announced to connect the industrial centres of England.
