Planetary Nebula A6639 approx. 5ly across. The nebula consists of an expanding shell of ionized gas—predominantly oxygen, which gives it a distinct blue-green or teal glow. Discovered in 1955 by Abell and Wilson in the Palomar Observatory Sky Survey. #astronomy #stellarastronomy #astrophotography
The Pleiades, or "Seven Sisters" (Messier 45), is a prominent open star cluster in the Taurus constellation. Comprised of young, hot blue stars, easily visible to the naked eye. 91min stack #SASPro #SVBONY #SC571CC #Stellarmate #astrophotography #DSO #space #astronomy #stellarastronomy

IC 405, AKA the Flaming Star Nebula, is an emission and reflection nebula in the constellation Auriga, about 1,500 ly away, famous for its fiery appearance caused by the hot, blue star AE Aurigae at its center. The red color comes from energized hydrogen gas. #stellarastronomy #IC405 #astronomy

Formation and evolution of the Solar System (Planetary science 🪐)
There is evidence that the formation of the Solar System began about 4.6 billion years ago with the gravitational collapse of a small part of a giant molecular cloud. Most of the collapsing […]

Color-Magnitude Diagram (CMD) of globular cluster M55. Each dot represents a star, its color indicating temperature (red=cool, blue=hot), and position showing brightness and color index (B-V). The diagram reveals distinct stellar populations: main sequence, red giant branch, and blue giants, illustrating stellar evolution and cluster age.

Hubble Space Telescope image of RS Puppis, a Cepheid variable star 6,500 light-years away, surrounded by a dazzling reflection nebula. The star's pulsations create a light echo visible in the nebula, allowing astronomers to precisely measure its distance and luminosity. This contributes to a more accurate cosmic distance scale.
