﻿ 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. 2024 February 6 [2]Spiral galaxy NGC 1566 is shown with an image from Hubble primarily in visible light on the upper left, and an image from Webb in primarily infrared light on the lower right. A rollover image shows the same galaxy with the Webb and Hubble parts reversed. Please see the explanation for more detailed information. NGC 1566: A Spiral Galaxy from Webb and Hubble Image Credit & Copyright: [3]NASA, [4]ESA, [5]CSA, [6]STScI, [7]J. Lee (STScI), [8]T. Williams (Oxford), [9]R. Chandar (UToledo), [10]D. Calzetti (UMass), [11]PHANGS Team Explanation: What's different about this galaxy? Very little, which makes the [12]Spanish Dancer galaxy, [13]NGC 1566, one of the most typical and photogenic [14]spirals on the sky. There is something different about [15]this galaxy image, though, because it is a diagonal combination of two images: one by the [16]Hubble Space Telescope on the upper left, and the other by the [17]James Webb Space Telescope on the lower right. The [18]Hubble image was taken in [19]ultraviolet light and highlights the locations of [20]bright blue stars and [21]dark dust along the galaxy's impressive spiral arms. In contrast, the [22]Webb image was taken in [23]infrared light and highlights where the [24]same dust emits more light than it absorbed. In the rollover image, the other two sides of these images are revealed. Blinking between the two images shows which [25]stars are particularly hot because they glow brighter in ultraviolet light, and the difference between [26]seemingly empty space and infrared-glowing dust.
