On Monday, May 9, 2016, Mercury will transit across the sun. This rare event will begin at 7:11 AM EDT and will continue for more than seven hours. NASA's Solar Dynamics Observatory will watch this transit from start to finish, ultra high definition images of the event in near real time as it unfolds. This is the first time SDO has captured this transit, which hasn't occurred since 2006. It won't occur again until 2019. NASA Scientists use the transit method to learn more about planets both in our solar system and beyond. Scientists can monitor the brightness of stars, looking for dips in that brightness that signal a transiting planet. Using the transit method, scientists can determine the distance of these planets from their stars, as well as their size and composition. Upcoming missions like the Transiting Exoplanet Survey Satellite will use the transit method to search for planets orbiting nearby stars.
