The Synthesis of "spiral galaxy"

Explore spiral galaxies, the stunning star cities with swirling arms that are home to stars like our sun. Learn why our own Milky Way fits this type.

Discover barred spiral galaxies, a common galaxy type featuring a central bar of stars. Learn how this structure, like our own Milky Way's, impacts star formation.

Discover our home, the Milky Way. Learn about the barred spiral galaxy containing our solar system, billions of stars, and a central black hole.

Discover elliptical galaxies, the smooth, oval-shaped star cities that hold clues to the universe's history and evolution. Learn why they matter.

Discover irregular galaxies, the cosmic mavericks with no defined shape. Learn why these unique structures are vital for understanding star formation.

Discover the Andromeda Galaxy (M31), our closest major galactic neighbor, and learn about its future collision course with our own Milky Way.

What is a galaxy? Discover these vast cosmic islands of stars, gas, and dark matter held together by gravity. Explore our own Milky Way and beyond.

Discover the galactic bulge, the dense, star-packed heart of spiral galaxies like our Milky Way, and its connection to supermassive black holes.

Discover the Active Galactic Nucleus (AGN), a super-luminous region at a galaxy's heart, powered by a feeding supermassive black hole.

Explore galaxy evolution, the study of how galaxies form and change over billions of years, from early starbursts to the massive structures we see today.
