Within the excessive resolution telescopic image, a colorized stack of 61 inviting video frames, a turbulent array of photospheric convection cells tile the incandescent describe voltaic surface.

For this November 11, 2019 transit of Mercury, the innermost planet’s silhouette became a mere 1/200th the describe voltaic diameter. So even below sure daytime skies it became complicated to peek with out the relief of a derive describe voltaic telescope. Following its transit in 2016, this became Mercury’s 4th of 14 transits eventually of the describe voltaic disk in the 21st century. The next transit of Mercury shall be on November 13, 2032.
