It is the closest major galaxy to our own Milky Way and is one of the largest galaxies in the known universe, with a diameter of approximately 220,000 light-years. M31 contains an estimated one trillion stars and has enough gas and dust to create billions more. It is a spiral galaxy with beautiful, swirling arms dotted with bright, glowing clusters of hot, young stars. Its bright core is home to a supermassive black hole, weighing in at a staggering 70 million solar masses.

  • In terms of its appearance, the Andromeda galaxy is a stunning sight to behold. Its bright, glowing clusters of young, hot stars are blue and white, while the cooler, older stars that make up the bulk of the galaxy have a yellowish hue. The vast clouds of gas and dust that lace the galaxy are pink and red, adding to its already breathtaking beauty. When viewed from Earth, the Andromeda galaxy appears as a hazy, white patch in the night sky, but closer observations reveal its true colors and splendor. It is truly a majestic and awe-inspiring sight, a testament to the vastness and beauty of the universe we call home.
