🌌 Small but mighty! Sextans A, a dwarf galaxy just 5,000 light-years wide, forms stars in a gumdrop-shaped region 4.5M light-years away. Proof that spirals don't get all the fun.

📸 Irregular Dwarf Galaxy Sextans A
This tiny galaxy, just 5,000 light-years wide, glows with young blue stars and pink star-forming regions. It lies 4.5 million light-years away in Sextans, on the edge of our Local Group.

A deep-space image of the irregular dwarf galaxy Sextans A, located near the center of the frame. The galaxy appears as a small, faint, gumdrop-shaped cluster with bright blue and pink patches indicating young star clusters and star-forming regions. It is surrounded by a dense field of stars, including several bright yellow and white foreground stars from the Milky Way, which have diffraction spikes from the telescope optics. The background is filled with countless faint stars and distant galaxies.

Image of Sextans A, an irregular galaxy located 10 million light-years away in the Local Group. The gumdrop-shaped galaxy displays bright, young blue star clusters against a backdrop of yellowish Milky Way foreground stars. This image showcases the beauty and star-forming activity of a less-celebrated type of galaxy.
