From high above the US, you might notice strange barcode-like markings on the ground. These symbols were once used to calibrate aerial and satellite cameras back in the 20th century, painted onto concrete or asphalt in black or white. Acting like eye charts for cameras, they helped fine-tune imaging equipment and determine optical resolution limits. And they aren't the only cool and weird things you'll find in the US. Let's talk about more mysterious things with an explanation. #brightside Credit: By NASA Goddard Space Flight Center: Phytoplankton bloom: https://flic.kr/p/8sMD3K, https://commons.wikimedia.org/w/index...
