Astronomy Picture of the Day [1]Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2023 May 16 [2]A deep image of the Sun's surrounding corona during the April 2023 total solar eclipse. The central disk is dark and many bright and complex rays are seen extending out. A few hot pink filaments can be seen just around the Sun's edge. Please see the explanation for more detailed information. Total Eclipse: The Big Corona Image Credit & Copyright: [3]Reinhold Wittich Explanation: Most photographs don't adequately portray the magnificence of the [4]Sun's corona. Seeing the [5]corona first-hand during a total [6]solar eclipse is [7]unparalleled. The [8]human eye can adapt to see coronal [9]features and [10]extent that average cameras usually cannot. Welcome, however, to the [11]digital age. The featured image [12]digitally combined short and long exposures taken in [13]Exmouth, [14]Australia that were processed to highlight faint and extended features in the corona during the total solar eclipse that occurred in [15]April of 2023. Clearly visible are [16]intricate layers and glowing caustics of an ever changing mixture of hot gas and [17]magnetic fields in the Sun's corona. [18]Looping prominences appear bright pink just past the Sun's [19]edge. Images taken seconds before and after the total eclipse show glimpses of the background Sun known as [20]Baily's Beads and [21]diamond ring effect. The next total [22]solar eclipse will cross [23]North America in [24]April of 2024.
