2021 January 21 - M78 Wide Field
Channel: APOD Podcast
Date: 21/01/2021

In today's image, we see M78, a part of the Orion star forming region. The red glow is due to emission from hydrogen gas. The blue nebula is due to the refection of starlight off of dust grains and the darkest areas are denser regions of dust obscuring regions of star formation.
