Close up, these images show large cell-like structures hundreds of kilometers across and, for the first time, the smallest features ever seen on the solar surface, some as small as 30km. The cell-like structures are violent motions that transport heat from the inside of the sun to its surface. Hence the need for the DKIST. What you’re seeing is Earth’s defence mechanism against space weather. For now, the warning time is about 48 minutes, but 48 hours is the ambition, which would help electricity grids to prepare and satellite operators to put their hardware into a safe mode. If the solar wind from the sun that envelopes Earth contains more charged particles than usual, it’s called a solar storm, and it can affect satellite communications and bring down power grids, causing long-lasting blackouts and disabling technologies such as GPS. In this picture taken at 789nm, we can see features as small as 30km (18 miles) in size for the first time ever. They show the surface of the Sun in the most exquisite detail we've ever seen - revealing convection granules the size of Texas, and tiny magnetic features - the roots of fields that extend far into space.The telescope that delivered these goods is the National Science Foundation's Daniel K. Inouye Solar Telescope on Haleakalā, Maui. The “NSF’s Inouye Solar Telescope will be able to map the magnetic fields within the sun’s corona, where solar eruptions occur that can impact life on Earth,” said France Córdova, NSF director. “The Inouye Solar Telescope will collect more information about our sun during the first 5 years of its lifetime than all the solar data gathered since Galileo first pointed a telescope at the sun in 1612.”Ultimately, what solar scientists want these missions to do is to help them understand not just the relationship between the sun and the Earth, but how stars and planets throughout the galaxy are magnetically connected. We can't wait to see what else it has to show us.Highest-resolution photo of the Sun's surface ever taken. That in turn causes space weather and, in some cases, raging solar storms. This handout photo, released Jan. 29, 2020, from the Daniel K. Inouye Solar Telescope shows the highest resolution image of the sun's surface ever taken. The Daniel K. Inouye Solar Telescope has produced the highest resolution image of the Sun’s surface What does the sun look like? “It’s all about the magnetic field,” said Rimmele. The corona—or crown—is the outer, and hotter, of the sun’s atmosphere. What we need is to grasp the underlying physics behind space weather, and this starts at the Sun, which is what the Inouye Solar Telescope will study over the next decades. Revealing unprecedented detail of the sun’s surface, the image marks “first light” at the National Science Foundation’s new The sun is a star 93 million miles from Earth that burns around five million tons of hydrogen fuel every second. atmosphere – is during a total solar eclipse, like this one on August 21, 2017 across the US (Photo by: VW Pics/Universal Images Group via Getty Images) “This image is just the beginning,” said David Boboltz, program director in NSF’s division of astronomical sciences and who oversees the facility’s construction and operations. The end result could be a more accurate and faster prediction of space weather. Built by NSF’s “We will be able to perform the most challenging measurements of the sun,” said Thomas Rimmele, director of the DKIST. “This telescope will improve our understanding of what drives space weather and ultimately help forecasters better predict solar storms.”The sun’s magnetic field is key to understanding its physical processes, and so predicting them—and therefore space weather “events.” These first images from the DKIST of the sun’s surface in close-up reveal the motions of the sun's plasma, which tangle and twist the star’s magnetic fields. "On Earth, we can predict if it is going to rain pretty much anywhere in the world very accurately, and space weather just isn't there yet," "Our predictions lag behind terrestrial weather by 50 years, if not more. telescope can image a region of the Sun 38,000km wide. In this picture taken at 789nm, … The US state of Texas is around 1,270 kilometres (790 miles) long.Just taking it all in is pretty amazing, but of particular interest to scientists are those magnetic fields, twisted and tangled by plasma, which can result in powerful This is what scientists are hoping the Inouye Solar Telescope will help to improve. Aurora Borealis, the Northern Lights, over the Vestrahorn mountain in the east of Iceland. Before you go and blind yourself by looking at our nearest star with your naked eyes, do yourself a favour and instead check out this image—the most detailed ever. "It is literally the greatest leap in humanity's ability to study the Sun from the ground since Galileo's time," Each granule is almost beyond comprehensively large - up to 1,600 kilometres (994 miles) across.
These first images from the DKIST show a close-up view of the sun’s surface, notably a pattern of turbulent “boiling” plasma that covers the entire star. Inouye should help solar scientists image the sun’s magnetic features and help build a model of its magnetic field. Highest-resolution photo of the Sun's surface ever taken. “On Earth, we can predict if it is going to rain pretty much anywhere in the world very accurately, and space weather just isn’t there yet,” said Matt Mountain president of AURA, which manages the DKIST.
