Seeing the sun set can already be a breathtaking experience, but observing the sun with a solar telescope reveals incredible details — such as sunspots and solar filaments — that we could never safely see with our naked eye. Full screen HD the video above, captured by Sweden-based astrophotographer Göran Strand. He writes:
Yesterday I went out to shoot a sunset I’ve planned since last summer. This time of the year, the Sun passes right behind a big radar tower if you stand at the Swedish National Biathlon Arena in Östersund. The radar tower is located about 10 km away from the arena in a small village called Ås. I shoot the movie using my solar telescope to capture the structures on the Sun. The timing was perfect and the Sun looked really nice since it was full of sunspots and big filaments.

Let’s move even closer. Courtesy of NASA’s Interface Region Imaging Spectrograph (IRIS), we can continue to witness the incredible power of our closest star. Recorded on May 9, 2014, this coronal mass ejection was the first giant solar eruption recorded by IRIS:
