Galaxies are enormous systems of stars, gas, dust, dark matter, and black holes bound together by gravity. They range from small dwarf galaxies containing millions of stars to giant galaxies containing trillions. Our Milky Way is only one of billions of galaxies spread throughout the…
Continue reading... Star clusters are groups of stars that formed from the same giant cloud of gas and dust. Because the stars in a cluster formed at roughly the same time and from similar material, they provide valuable insight into how stars evolve over time. Astronomers divide…
Continue reading... Nebulae are enormous clouds of gas and dust found throughout galaxies. They are closely connected to the life cycles of stars, serving as regions where stars form, evolve, and eventually return material back into space. Most nebulae consist primarily of hydrogen and helium along with…

These towering columns of gas and dust are located within the Eagle Nebula (M16), approximately 6,500–7,000 light-years from Earth in the constellation Serpens. They became world-famous after the Hubble Space…
