The Andromeda Galaxy is the closest large galaxy to our Milky Way and one of the most fascinating objects in the night sky. Located about 2.5 million light-years away from Earth, Andromeda is so massive that it contains nearly one trillion stars — far more than our own galaxy. On clear dark nights, it can even be seen with the naked eye as a faint glowing patch in the sky. Scientists have discovered that Andromeda and the Milky Way are slowly moving toward each other at incredible speed. Althoug

The Andromeda Galaxy in 5 types of light. 🌀 This new image shows the Andromeda Galaxy in 5 different types of light (X-ray, UV, optical, infrared, and radio) from some of the world’s most powerful telescopes, including NASA’s Chandra X-ray Observatory. Andromeda, also known as M31, is the closest spiral galaxy to the Milky Way at a distance of about 2.5 million light-years. This image is being released in tribute to the groundbreaking legacy of Dr. Vera Rubin, whose observations transformed our

Zoom into the Andromeda galaxy The largest NASA Hubble Space Telescope image ever assembled, this sweeping view of a portion of the Andromeda galaxy (M31) is the sharpest large composite image ever taken of our galactic neighbor. Though the galaxy is over 2 million light-years away, the Hubble telescope is powerful enough to resolve individual stars in a 61,000-light-year-long section of the galaxy's pancake-shaped disk. It's like photographing a beach and resolving individual grains of sand. An
