The observable universe is estimated to be about 93 billion light-years in diameter, containing billions of galaxies, each with billions of stars.
Black holes are incredibly dense regions in space where gravity is so strong that nothing, not even light, can escape their grasp.
Pulsars are rapidly rotating neutron stars that emit beams of electromagnetic radiation. They can spin hundreds of times per second and act like cosmic lighthouses.
Jupiter's Great Red Spot is a massive storm that has been raging for at least 350 years, making it one of the most persistent features in the solar system.
The universe's large-scale structure resembles a cosmic web, with vast filaments of dark matter and galaxies interconnected in a network.
The afterglow of the Big Bang, known as the Cosmic Microwave Background, is a faint glow of radiation that fills the entire universe and provides valuable insights into its early stages.
Launched in 1977, Voyager 1 is the farthest human-made object from Earth and has entered interstellar space, leaving our solar system behind.
Light travels at an astonishing speed of approximately 299,792 kilometers per second (about 186,282 miles per second), making it the fastest thing in the universe.
Located in the Eagle Nebula, the Pillars of Creation are vast columns of gas and dust where new stars are forming, captured in a famous Hubble Space Telescope image.
Scientists have discovered thousands of exoplanets (planets outside our solar system), some of which are located in the "habitable zone" where conditions might support life as we know it.
