Orion: The Running Man Nebula

Image Credit & Copyright: Robert G. Lyons (Robservatory)
Explanation: What part of Orion is this? Just north of the famous Orion Nebula is a picturesque star forming region in Orion's Sword that contains a lot of intricate dust -- some of which appears blue because it reflects the light of bright embedded stars.

Ou4: The Giant Squid Nebula

Image Credit & Copyright: Massimo Di Fusco
Explanation: Difficult to capture, this mysterious, squid-shaped interstellar cloud spans nearly three full moons in planet Earth's sky. Discovered in 2011 by French astro-imager Nicolas Outters, the Squid Nebula's bipolar shape is distinguished here by the telltale blue emission from doubly ionized oxygen atoms.

Image Credit: NASA, WISE, IRSA; Processing & Copyright : Francesco Antonucci
Explanation: How do stars form? Images of the star forming region W5 like those in the infrared by NASA's Wide Field Infrared Survey Explorer (WISE, later NEOWISE) satellite provide clear clues with indications that massive stars near the center of empty cavities are older than stars near the edges.

Comet ATLAS Rounds the Sun

Image Credit: NASA, SOHO Spacecraft, LASCO C3; Processing: Rolando Ligustri
Explanation: Why does Comet ATLAS have such colorful tails? Last week Comet C/2024 G3 (ATLAS) passed its closest to the Sun -- well inside the orbit of Mercury -- and brightened dramatically. Unfortunately, the comet was then so angularly near the Sun that it was very hard for humans to see.
