3 days ago · Orion Arm. The Orion Arm, also known as the Orion–Cygnus Arm, is a minor spiral arm within the Milky Way Galaxy spanning 3,500 light-years (1,100 parsecs) in width and extending roughly 20,000 light-years (6,100 parsecs) in length. [2] This galactic structure encompasses the Solar System, including Earth.
Jul 3, 2024 · The Milky Way Project aims to sort and measure our galaxy. We're asking you to help us find and draw bubbles in beautiful infrared data from the Spitzer Space Telescope. Understanding the cold, dusty material that we see in these images, helps scientists to learn how stars form and how our galaxy changes and evolves with time.
