On July 5th the SOlar and Heliospheric Observatory (SOHO) captured video of a comet, known as a sungrazer, in route to collide with our star. SOHO is equipped with an occluding coronograph that blocks direct sunlight and reveals the corona, but also prevents direct study of the terminal impact of sungrazers. But on July 6th, with the help of the Solar Dynamics Observatory (SDO), astronomers were able to observe the comet (slyt) streaking in front of the surface of the sun for the first time in history. It likely disintegrated before impact due to extreme heat and radiation.
