The National Science Foundation’s (NSF) Daniel K Inouye Solar Telescope (DKIST) in Hawaii captured the clearest photo of the Sun yet.

The clearest photo of the sun

New images reveal the sun’s surprising surface grain structure as a plasma that resembles gold, with each grain having an area similar to that of France’s Grand Prince.

These plasma columns, whose temperature rises to nearly 6,000 degrees Celsius, violently release energy and sink through the gaps between particles after cooling. This kind of complex observational details will help humans improve their understanding of solar activity and make more accurate predictions.

It is reported that the original name of DKIST was New Technology Solar Telescope (ATST), but in December 2013, in order to commemorate the death of Hawaii State Senator Daniel Ken Inouye (Daniel Ken Inouye), the team changed its name to Daniel K Inouye Solar telescope. Daniel Inoue passed away on December 17, 2012.

DKIST’s primary mirror is 4.24 meters wide and 75 millimeters thick. It uses a special adaptive optical system and is paired with a smaller secondary mirror to observe the surface of the sun very clearly. Its magnification is equivalent to seeing the outline of a one-inch coin from 100 kilometers away.
