Stellar Diversity: There are over 100 billion stars in our Milky Way galaxy alone, and there are billions of galaxies in the observable universe, each with its own set of stars.
Twinkling Stars: Stars appear to twinkle due to the Earth’s atmosphere distorting their light as it passes through.
Nuclear Fusion: Stars shine because of nuclear fusion in their cores, where hydrogen atoms combine to form helium, releasing immense energy in the process.
Color Varieties: Stars come in different colors, from red (cooler) to blue (hotter), with yellow (like our Sun) falling in between.
Supernova Explosions: Some stars end their lives in spectacular explosions called supernovae, briefly outshining entire galaxies.
Black Holes: Massive stars can collapse into black holes, where gravity is so strong that nothing, not even light, can escape.
Neutron Stars: Extremely dense remnants of massive stars, neutron stars can spin hundreds of times per second and have incredibly strong magnetic fields.
Stellar Nurturers: Stars, through their lifecycles, create and distribute elements, including carbon, oxygen, and iron, which are essential for life.
Hubble’s Law: The universe is expanding, as Edwin Hubble discovered, which means galaxies are moving away from each other, including our Milky Way.
White Dwarfs: Sun-sized stars end as white dwarfs, incredibly dense objects with the mass of a star packed into a sphere the size of Earth.
Binary Stars: Many stars exist in binary or multiple star systems, where two or more stars orbit each other.
Red Giants: Stars like our Sun will expand into red giants in their later stages, eventually shedding their outer layers.
Stellar Nurseries: Nebulas are vast clouds of gas and dust where new stars are born. The famous Eagle Nebula is one such stellar nursery.
Speed of Light: The light from the closest star to Earth (besides the Sun), Proxima Centauri, takes over four years to reach us.
Age of Stars: Some stars in the Milky Way are estimated to be over 13 billion years old, making them almost as old as the universe itself.
