The Day of the Trifid Nebula

NASA celebrates Hubble’s 36th anniversary with a new image of the Trifid Nebula, a star-forming region it first captured in 1997. The telescope leveraged almost its full operational lifetime to show us changes in the nebula on human time scales with an improved camera. via NASA https://ift.tt/GZAn6PL

NASA's SPHEREx Observatory Maps Interstellar Ice in Milky Way

An observation made by NASA’s SPHEREx mission reveals vast frozen complexes in the Cygnus X star-forming region of the Milky Way galaxy. The chemical signature of water ice is shown as bright blue structures, while polycyclic aromatic hydrocarbons are in orange. via NASA https://ift.tt/F5JudxA

At the Edge of Light
