IMAGES from a powerful new telescope installed on top of a volcano in Hawaii show the surface of the sun in the closest detail yet, revealing features as small as 30km across. They were captured by the National Science Foundation’s (NSF) Daniel K. Inouye Solar Telescope, which sits at around 10,000 feet above sea level near the summit of Haleakala volcano in Maui, Hawaii.

The telescope, which features the world’s largest solar 13 feet mirror, could enable a greater understanding of the sun and its impact on our planet, according to the National Solar Observatory, a public research institute headquartered in Boulder, Colorado.

A pattern of turbulent, “boiling” gas is shown covering the sun, which is some 93 million miles from Earth. Inside visible cell-like structures, each around the size of the US state of Texas, hot plasma can be seen rising before cooling off and sinking below the surface in dark lanes, as part of a process called convection. Markers of magnetic fields are also visible with new clarity, the NSO said.

“This telescope will improve our understanding of what drives space weather and ultimately help forecasters better predict solar storms,” said France Crdova, NSF director.
