Did you know that our solar system is located within the Milky Way galaxy, which is just one of billions of galaxies in the universe? The Milky Way is estimated to be over 100,000 light-years in diameter and contains around 100 billion stars. Another fascinating fact is that black holes are regions in space where gravity is so strong that nothing, not even light, can escape. They are formed when massive stars collapse at the end of their life cycle. Despite their name, black holes actually emit radiation and can be detected by telescopes. In terms of size, the largest known star is UY Scuti, which is a red supergiant located in the constellation Scutum. It is estimated to be over 1,700 times larger than the Sun and would engulf all the inner planets in our solar system if it were placed at the center. Speaking of planets, did you know that Venus is the hottest planet in our solar system? Despite being the second closest planet to the Sun, it is hotter than Mercury due to its thick atmosphere that traps heat. The average surface temperature on Venus is about 900 degrees Fahrenheit. Lastly, the famous Hubble Space Telescope has provided us with stunning images of distant galaxies and nebulae since its launch in 1990. It orbits Earth at an altitude of about 340 miles and has revolutionized our understanding of the universe.
