Asianet.id – Para astronom baru saja merilis pengamatan dari Daniel K. Inouye Solar Telescope milik National Science Foundation. Tim astronom membagikan potret dan video baru yang luar biasa dari cakram Matahari dengan detail paling jelas, menampilkan struktur sekecil 30 kilometer.

Mengutip NY Times, potret permukaan Matahari ini nampak memperlihatkan warna emas dengan bentuk mirip nugget yang terbagi dalam beberapa bagian yang kemudian menjad satu.

Para astronom menjelaskan bahwa bagian tengah Matahari ini adalah pusat pelepasan panas dengan suhu mencapai 6 ribu derajat celcius. Bagian sekeliling Matahari nampak memiliki bagian gelap yang disebut-sebut menjadi tempat plasma Matahari mendingin.

Potret detail itu dapat diambil berkat cermin setebal 4 meter di Daniel K. Inouye Solar Telescope. Terletak di gunung berapi wilayah Maui, Hawaii, dan ditempatkan di ketinggian 3 ribu meter.

This is the most detailed image of the Sun ever taken. ​ ​Astronomers have just released the “first-light” observations from the National Science Foundation’s Daniel K. Inouye Solar Telescope. The team revealed incredible new images and videos of the solar disk in unprecedented detail, showcasing structures as small as 30 kilometers (18 miles). The achievement was only possible thanks to its 4-meter (13-foot) mirror, which makes the Inouye Solar Telescope the largest solar telescope in the world. Still, the act of actually observing the Sun is not an easy task. The main mirror focuses 13 kilowatts of power, generating an incredible amount of heat. For this reason, a cooling system is in place to protect the instruments and make the observatory accessible for the researchers. The achievement is more than 20 years in the making. “Since NSF began work on this ground-based telescope, we have eagerly awaited the first images,” France Córdova, National Science Foundation director, said in a statement. “We can now share these images and videos, which are the most detailed of our Sun to date. 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. This telescope will improve our understanding of what drives space weather and ultimately help forecasters better predict solar storms.” Future observations from the Solar Telescope will reveal more about how the Sun's outer layers change over time and the underlying magnetic processes that happen deep within them. This will aid researchers in their quest to understand better our star and how it affects us. Predicting solar storms is still beyond our ability, but the data from the telescope will help in that effort. “These first images are just the beginning,” said David Boboltz, a program director in NSF’s Division of Astronomical Sciences who oversees the facility’s construction and operations. “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.” ​Image: NSO/AURA/NSF

“Sejak National Science Foundation (NSF) mulai mengembangkan teleskop berbasis darat ini, kami dengan sabar menunggu gambar pertama. Kami sekarang dapat membagikan gambar dan video ini, yang merupakan rincian paling detail dari Matahari hingga saat ini. Inouye Solar Telescope NSF akan dapat memetakan medan magnet di dalam korona Matahari, tempat terjadi letusan Matahari yang dapat memengaruhi kehidupan di Bumi,” ucap France Córdova, Direktur National Science Foundation.

Dilansir dari IFL Science, pengamatan masa depan dari Solar Telescope akan mengungkapkan, lebih banyak pengetahuan tentang bagaimana lapisan luar Matahari berubah dari waktu ke waktu dan proses magnetik yang terjadi di dalamnya.

Ini akan membantu para ilmuwan dalam memahami Matahari dengan lebih baik dan bagaimana pengaruhnya terhadap manusia.
