From its creator: Are there any dangers associated with receiving an MRI and how exactly does an MRI work? Is it safe? Medical imaging, specifically magnetic resonance imaging (MRI), has come so far that we can create high resolution images of the entire body. The technology utilizes a cylindrical cavity surrounded by a giant electromagnet, and the magnetic field though the cavity is used to image body tissue.

During the afternoon of March 9, 2016, a total solar eclipse was visible in parts of southeast Asia. An eclipse occurs when the moon passes directly between Earth and the sun. The MODIS instrument on NASA's Aqua satellite captured this image of the total solar eclipse moving across the south Pacific Ocean at 03:05 UTC on March 9, 2016. via NASA http://ift.tt/1W99nJh
