Unlocking the Secrets of the Milky Way

✨The stars in our universe clump together to form galaxies, massive celestial systems consisting of countless stars, planets, and nebulae.

🔍Galaxies are diverse in structure, ranging from young, spiral galaxies with beautiful spiral arms, to older, spherical galaxies.

🌌The Milky Way is our galaxy, with the stars in it unevenly distributed forming a thick bar in the center and huge spirals extending from it.

🌍Our Earth is located in the Orion Arm of the Milky Way, a perfect location for the emergence and survival of life.

🔭The Gaia and UCLID telescopes are helping scientists survey and map the Milky Way, providing valuable insights into its formation and development.

What are galaxies?

—Galaxies are massive celestial systems consisting of billions of stars, bound together by gravity, and surrounded by planets, gas, and dust.

What is the Milky Way?

—The Milky Way is our galaxy, a spiral galaxy with a thick bar in the center and huge spiral arms extending from it.

What is dark matter and dark energy?

—Dark matter and dark energy are mysterious forces that make up the majority of the universe. Dark matter is responsible for the gravitational effects within and between galaxies, while dark energy drives the accelerated expansion of the universe.

What is a supermassive black hole?

—A supermassive black hole is a black hole with a mass that is millions or billions of times that of our sun. They are found at the center of galaxies, including the Milky Way.

What are the Gaia and UCLID telescopes?

—The Gaia telescope is surveying and mapping the Milky Way, while the UCLID telescope is investigating dark matter and dark energy to understand the expansion of the universe.
