    • The galactic center is invisible in optical due to dust. If you open Aladin Lite ( https://aladin.u-strasbg.fr/AladinLite/ ) and plug in Sagittarius A*, you will find a tiny handful of stars in front of a dense dust cloud. Switching the image source to DECaPS, you can see a faint red glow as the cloud becomes less opaque in very-near-infrared. Moving just a bit further into infrared with 2MASS, you can see the galactic center showing up in the near-mid infrared bands H and K (green/red). By the time you get to proper mid-infrared observatories like WISE, the entire galactic center is a blinding white, saturating every single band.

  • I read that there are high concentrations of interstellar dust and gas near the center of the galaxy that make it difficult to resolve stars. If Earth were orbiting a planet very near to the galactic center, would space appear “hazy” instead of clear and black?
