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

Important news about the Stellar Astronomy feed: we have removed #stars as a way to post to this feed due to false positives - as with the other subtopic feeds, it's only intended for scientific posts!

You can now only post to it with #stellarastronomy or #stellarastro.

Did you know that some stars are born in pairs or even larger groups, called multiple star systems? These stars orbit each other, their gravitational dance a beautiful and complex ballet across the cosmos. #BinaryStars #StellarAstronomy #SpaceFacts

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 precise distance measurement. This contributes significantly to understanding cosmic distances.

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

The chemical composition of a star can change over its lifetime due to nuclear fusion processes in its core and mixing within the star's interior. Studying these changes helps astronomers understand the nuclear processes at play and the star's evolutionary history.

The distribution of stars within a galaxy is influenced by the galaxy's spiral arms, with young, massive stars predominantly found within the spiral arms, while older, less massive stars are more distributed throughout the galactic disk and halo.

The habitable zone around a star, where liquid water could potentially exist on a planet's surface, is not a fixed distance but depends on the star's luminosity and temperature. Larger, hotter stars have more distant habitable zones compared to smaller, cooler stars.
