Insights on "Hubble sequence"
Discover elliptical galaxies, the smooth, oval-shaped star cities that hold clues to the universe's history and evolution. Learn why they matter.
Discover the Hubble Space Telescope, a revolutionary observatory that has transformed our understanding of the cosmos for over three decades of service.
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.
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 the main sequence, the longest stage of stellar evolution where stars like our Sun fuse hydrogen into helium, providing stable energy.
Discover Cepheid variables, the pulsating stars that act as cosmic yardsticks, allowing astronomers to measure vast distances across the universe.
Discover the James Webb Space Telescope (JWST), NASA's infrared observatory revolutionizing our view of the early universe and distant worlds.
Discover how space telescopes like Hubble and James Webb orbit above Earth to capture stunning, unobstructed views of the universe's greatest wonders.
Explore the Hertzsprung-Russell diagram, the cornerstone chart astronomers use to classify stars by temperature, luminosity, and evolutionary stage.
Discover cosmological redshift, the key evidence for the expanding universe. Learn how light from distant galaxies stretches as space itself expands.
