Solar System
Our solar system is a gravitationally bound collection of the Sun, its eight planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune), dwarf planets like Pluto, moons, asteroids, and comets, all orbiting the central star, the Sun. Formed from a collapsing cloud of gas and dust about 4.6 billion years ago, it’s located in the Orion Arm of the milky way, with the Sun holding most of the system’s mass and providing the light and heat that sustains life on Earth.
Satellite Roaming
NASA satellites, such as the Aqua and Terra earth-observing fleet, silently roam in low Earth orbit, orbiting the planet every 90 to 100 minutes at speeds over 17,000 mph. These orbital robots use advanced sensors to monitor climate change, track wildfires, and measure ocean health, acting as vigilant, automated sentinels.
Space Nebula
A nebula is a vast, interstellar cloud of dust, hydrogen, helium, and other ionized gases, often stretching across hundreds of light-years of space. Serving as cosmic nurseries, these vibrant, often colorful clouds are the birthplaces of new stars, where gravity pulls material together until it collapses and ignites.
