新しく撮影された太陽の画像は、これまでで最も詳細なもので、その表面が奇妙な動的な外観を見せています。これらの画像は、ハワイ州 Maui島にある国立科学財団の Daniel K. Inouye 太陽望遠鏡を使用して、研究者が太陽の明るい外殻をより高い解像度で捉えたものです。
この画像には、太陽表面に奇怪な羽のようなパターンが見られ、これは「ヴァン・ゴッホの星夜」に描かれたような印象を与えるという。研究によると、太陽表面の不規則な波は、異なる速度で移動する磁化プラズマによって引き起こされるものです。
研究者らはこの現象を観測し、「地球上や木星、土星など他の惑星でも同様の現象が見られるが、太陽表面での観測はこれまでになかった」と述べています。これらの研究成果は「ネイチャー」誌に発表されました。
An anonymous reader quotes a report from the Associated Press: Scientists have captured images of the sun's surface in the finest detail yet, revealing a strange and dynamic facade. It's dangerous to look directly at the sun without proper eye protection. But researchers were able to peek at its scorching surface with the help of the National Science Foundation's Daniel K. Inouye Solar Telescope, located on the island of Maui in Hawaii.
Scientists originally took the images for a different reason: to fine-tune and test the limits of the telescope. But when they looked at the results, they realized they'd photographed the sun's bright outer shell at higher resolution than ever before. What's more, they saw strange feathery patterns rippling across the surface. "That reminds me of famous paintings, like the swirling skies in Van Gogh's Starry Night," said solar physicist Ruizhu Chen with Stanford University, who was not involved with the new research.
Researchers saw ripples of instability on the sun's surface caused by bits of magnetized plasma moving past each other at different speeds -- similar to waves that stir when a gust of wind blows over water. It's a well-known phenomenon that guides how fluids move. This has been glimpsed on Earth and other planets like Jupiter and Saturn, but "it has not been observed ever at that level on the solar surface," according to study co-author Friedrich Woger with the National Solar Observatory. The findings were published Wednesday in the journal Nature.
