The National Science Foundation, with a 4.24 m mirror, was honored by two impressive images of a star that had not yet been produced.
The first image captures the sun's chromosphere, the outer shell of the star, which is very problematic to observe from the Earth's surface because of the high radiation of the photosphere and the lower atmosphere. You can see the chromosphere during the solar eclipse when the moon blocks the bright light of the star.
The second image reveals in more detail the image of the Sun's chromosphere, and it shows many so-called "grave", each of which is 500 to 1,500 km wide. This image was also taken during the observation of the Sun on June 3.
Due to the large spatial resolution and high sensitivity, the DKIST telescope can distinguish the relatively small details in the Sun's photosphere. By doing so, scientists can closely monitor the coronal mass emissions and determine the voltage and direction of the magnetic field in the chromosphere and the star's crown.
