Deep space orbits extend far beyond the planets of our solar system and include the paths of distant comets, interstellar objects, spacecraft, and stars moving within galaxies. These enormous trajectories follow the same fundamental laws of gravity and orbital motion seen in smaller systems, but…
Continue reading... Black holes are regions of space where gravity becomes so intense that nothing crossing a boundary called the event horizon can escape. Formed through the collapse of massive stars or through mergers and other extreme processes, black holes represent some of the strongest gravitational environments…
Continue reading... Exoplanets are planets that orbit stars beyond our solar system. Like the planets orbiting our Sun, they follow the same fundamental laws of gravity and orbital motion. However, observations of exoplanet systems have revealed an enormous variety of orbital arrangements that have reshaped scientific understanding…
Continue reading... Galaxies are enormous collections of stars, gas, dust, and dark matter bound together by gravity. Like smaller orbital systems, galaxies rotate around a common center, but on scales spanning tens or even hundreds of thousands of light-years. Studying galactic rotation helps astronomers understand the structure,…
Continue reading... Most stars in the universe are part of systems containing two or more stars bound together by gravity. These stellar systems can also include planets, asteroids, comets, and surrounding debris. Although far larger and more complex than planetary systems, they follow the same fundamental principles…
