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 it’s “stellar” is an understatement. Simply put, it’s amazing. The high-resolution images were taken with the currently fully operational Daniel K. Inouye Solar Telescope, located atop Haleakala, Maui, in Hawaii. Scientists say the new observatory – with its large 4 meter (13 ft) primary mirror – will enable a new era of sun science, and provide a leap forward in understanding the sun and its effects on our planet.

The image above shows a region 82,500 kilometers wide with a resolution of 18 kilometers, and it shows a region on the Sun where temperatures can reach 7,200°C (13,000°F). The photos were taken on June 3 this year and released to the public this week. The National Science Foundation (NSF) says the Inoue Solar Telescope is nearing completion of its first year of Operations Commissioning Phase (OCP), and it is “fulfilling its promise to detect the Sun in ways never seen before.”

The Inouye telescope is currently the largest solar telescope in the world. While previous images were taken with the new telescope, full operations have been delayed due to the COVID-19 pandemic. Previous images included an impressive display of a sunspot and the highest resolution image of the sun ever taken, but we can expect to see more high-resolution images in the coming years. Scientists say advanced optics for the telescope and basic mirror Scientists will give the best view of the Sun from Earth throughout the next solar cycle.

With the telescope now operating at full capacity, the NSF held a ceremony on August 31, 2022, with science officials, dignitaries in Congress, members of the scientific and Native Hawaiian communities, as the telescope is located on a mountain of spiritual and cultural significance to him. Native Hawaiian people.

“With the world’s largest solar telescope now in scientific operations, we are grateful to everyone who made this remarkable facility possible,” said Matt Mountain, President of the Association of Universities for Research in Astronomy (AURA). Hawaii for the privilege of working from such a wonderful location, to the National Science Foundation and the US Congress for their continued support, and the Inouye Solar Telescope team, many of whom have tirelessly dedicated more than a decade to this transformative project. A new era of solar physics has begun.”

One of the primary goals of the Inouye Solar Telescope is to gain a better understanding of solar dynamics. This, in turn, will help scientists predict and prepare for solar storms, called coronal mass ejections (CME). The ejected coronal masses send hot plasma from the sun’s corona and, if Earth were in the path, could damage satellites in Earth’s orbit and interfere with the planet’s power grids. Scientists hope to be able to improve their predictions of major weather events. Nowadays, space agencies can anticipate events 48 minutes ahead of time. But with the new telescope, they hope to make predictions 48 hours in advance.

“NSF’s Inouye Solar Telescope is the most powerful solar telescope in the world that will forever change the way we explore and understand our sun,” said National Science Foundation director, Sethuraman Panchanathan. “Her visions will change how our nation and the planet anticipate and prepare for events like solar storms.”

The telescope His name was the late Hawaii senator Daniel K. Inoue. Haleakal means “house of the sun.”
