Summarize this article for a 10 year old
Iceberg A-74 is an iceberg that calved from the north side of the Antarctic Brunt Ice Shelf in February 2021. Its calving had been anticipated due to large ice rifts that opened up in September 2019 and spread in the Antarctic summer of 2020–21. The iceberg measured 1,270 square kilometres (490 sq mi) soon after calving. It has moved away from the Antarctic coast which allowed, on 13–14 March 2021, the research vessel Polarstern to complete a circumnavigation as part of a research expedition. The Polarstern has photographed the sea bed which has provided an insight into fauna that can survive up to 30 kilometres (19 mi) from the nearest daylight.
