by Holiday decorations may have come down already on Earth, but a nebula located 7,000 light-years away is keeping the festive spirit alive.
The Hubble Space Telescope captured a stunning image of a small region of Westerhout 5, also known as the Soul Nebula, glowing red.
The suffusion of red light is caused by H-alpha emission, which happens when very energetic electrons within hydrogen atoms lose energy, causing the release of this distinctive red light, Hubble representatives wrote in a description of the image.
This red light also reveals a range of fascinating features, such as a so-called free-floating evaporating gaseous globule (frEGG).
