Science Stories with Joe Johnson

Our resident science guy Joe Johnson is back with science stories that caught his eye recently, including Pando, believed to be the largest, most dense organism ever found at nearly 13 million pounds and spread over 106 acres in Utah; the latest on The Parker Solar Probe, the NASA spacecraft studying the sun's outer atmosphere, or corona, and its impact on the solar wind; and Kessler Syndrome, a nightmare space scenario in which the number of satellites and orbital space junk is so high that collisions occur.
