NASA's $10 billion space telescope studied the third interstellar object to enter the solar system, measuring the chemical contents of its halo.

New telescope images deliver sharpest-ever view of powerful solar flare. Astronomers have zoomed in on small loops of plasma within a powerful solar flare for the first time, potentially revealing the fundamental building blocks of the sun's violent storms. Images, captured with new Daniel K. Inouye Solar Telescope in Hawaii, reveal arcs of hot gas just 10 to 30 miles wide follow sun’s magnetic fields. Earlier instruments could only resolve loops 60 to 100 miles wide. Inouye's images are 2.5 times sharper. Scientists believe so-called "coronal loops" may in fact most basic pieces of solar flares — sudden explosions of energy hurl a torrent of radiation into space & toward Earth.

The discovery is giving a new window into how our host star makes flares in the first place. Gathering insight may lead to better space weather forecasts, & preventing future solar storms from wreaking havoc on satellites, power grids& radio signals.
"Knowing a telescope can theoretically do something is one thing," said Maria Kazachenko, a co-author in the study, in a statement. "Actually watching it perform at that limit is exhilarating." The solar observatory sits atop a dormant volcano, Haleakalā, towering over Maui at 10,000 feet above sea level. Fittingly, name Haleakalā means "house of the sun" in Hawaiian. But why site was selected for the telescope, summit special environmental conditions allow astronomers to better view sun's corona outer layer of its atmosphere. For study is published in The Astrophysical Journal Letters.
