This is from NASA’s YouTube description of this video:
February 11, 2015 marks five years in space for NASA’s Solar Dynamics Observatory, which provides incredibly detailed images of the whole sun 24 hours a day. Capturing an image more than once per second, SDO has provided an unprecedentedly clear picture of how massive explosions on the sun grow and erupt ever since its launch on Feb. 11, 2010. The imagery is also captivating, allowing one to watch the constant ballet of solar material through the sun’s atmosphere, the corona.
In honor of SDO’s fifth anniversary, NASA has released a video showcasing highlights from the last five years of sun watching. Watch the movie to see giant clouds of solar material hurled out into space, the dance of giant loops hovering in the corona, and huge sunspots growing and shrinking on the sun’s surface.
This new video from The SciShow on YouTube is about the Nobel Prize for medicine given to the developer of the lobotomy.
It’s of particular interest to me since my Uncle was one of a number of immigrant children from low-income families who were diagnosed with so-called behavior disorders and lobotomized. This practice took place in the 1940’s. He was institutionalized for the rest of his life following the procedure. I have vivid memories of his visits to us — from the moment he entered our home he was always looking at his watch concerned about getting back to the hospital on time.
