This nebula is on point 👆⁣⁣ ⁣⁣ Visible from Earth’s southern hemisphere, the Keyhole Nebula lies around 8,000 light-years within the Carina Nebula, an enormous cloud of gas and dust home to some of the brightest, most massive stars in the universe, each around ten times as hot and 100 times as massive as our Sun.⁣⁣ ⁣⁣ Captured by NASAHubble, the circular Keyhole structure contains dark silhouetted clouds of cold molecules and dust, and bright filaments of hot, fluorescing gas, all moving in chaotic, rapid motion, which may condense into a star if the clouds are dense enough. The diameter of the Keyhole ring structure seen here is seven light-years, the Carina Nebula has an overall diameter of over 200 light-years.⁣⁣ ⁣⁣ Image description: Blue, gray, and black clouds color the left side of the image, at the center of the swirling wisps of gas tumble chaotically in colors of red, orange, green, brown, black, and white.
