Fotografie + English: NGC 3627 (Hubble + Webb) (Uploaded on February 7, 2024)

• Face-on spiral galaxy, NGC 3627, is split diagonally in this image: The James Webb Space Telescope’s observations appear on bottom right, and the Hubble Space Telescope’s at top left. Webb and Hubble’s images show a striking contrast, an inverse of darkness and light. Why? Webb’s observations combine near- and mid-infrared light and Hubble’s showcase visible and ultraviolet light. Dust absorbs ultraviolet and visible light, and then re-emits it in the infrared. In Webb's images, we see dust glowing in infrared light. In Hubble’s images, dark regions are where starlight is absorbed by dust.
• In Webb’s high-resolution infrared images, the gas and dust stand out in stark shades of orange and red, and show finer spiral shapes with the appearance of jagged edges, though these areas are still diffuse.
• In Hubble’s images, the gas and dust show up as hazy dark brown lanes, following the same spiral shapes. Its images are about the same resolution as Webb’s, but the gas and dust obscure a lot of the smaller-scale star formation.

• Image description: Two observations of the galaxy NGC 3627 are split diagonally, with Hubble’s observations at top left and Webb’s at bottom right. The galaxy’s core appears just above center and largely contains Hubble’s observations. In Hubble’s image, the galaxy’s core and diagonal bar structure is a prominent oval that is pale yellow. The spiral arm that wraps to the top of the image is a mix of dark brown filamentary dust lanes and some bright blue star clusters. In Webb’s image, the spiral arm at right wraps to the bottom of the image and is in shades of orange.
