Insanely High-Resolution Images of the Sun Show its Chromosphere in Vivid Detail

New images of the Sun’s chromosphere – the lower region of the solar atmosphere — have been released, and to say they are ‘stellar’ is an understatement. Simply, they are stunning. The high-resolution images were taken with the now-fully-operational Daniel K. Inouye Solar Telescope, located on the summit of Haleakala, Maui, in Hawai‘i. Scientists say the new observatory — with its large 4-meter (13-ft) primary mirror — will enable a new era of solar science, and provide a leap forward in understanding the Sun and its impacts on our planet.

A Sunspot Seen by the Most Powerful Solar Telescope in the World

This is the first sunspot image taken on January 28, 2020 by the NSF’s Inouye Solar Telescope’s Wave Front Correction context viewer. The image reveals striking details of the sunspot’s structure as seen at the Sun’s surface. Image credit: NSO/AURA/NSF

A new image from the world’s largest solar observatory shows a spectacular, high resolution view of a gigantic sunspot. The sunpspot measures about 16,000 km (10,000 miles) across, large enough that Earth could fit inside.

This is the Highest Resolution Image Ever Taken of the Surface of the Sun

The Sun’s activity, known as “space weather”, has a significant effect on Earth and the other planets of the Solar System. Periodic eruptions, also known as solar flares, release considerable amounts of electromagnetic radiation, which can interfere with everything from satellites and air travel to electrical grids. For this reason, astrophysicists are trying to get a better look at the Sun so they can predict its weather patterns.

This is the purpose behind the NSF’s 4-meter (13-ft) Daniel K. Inouye Solar Telescope (DKIST) – formerly known as the Advanced Technology Solar Telescope – which is located at the Haleakala Observatory on the island of Maui, Hawaii. Recently, this facility released its first images of the Sun’s surface, which reveal an unprecedented level of detail and offer a preview of what this telescope will reveal in the coming years.
