Neutron stars are incredibly dense remnants of massive stars that have undergone supernova explosions. A teaspoon of neutron star material on Earth would weigh billions of tons.
Quasars are extremely bright and energetic galactic nuclei powered by supermassive black holes. Despite their immense luminosity, quasars are often smaller than our solar system.
As of now, over 4,000 exoplanets (planets outside our solar system) have been discovered. Some of these exoplanets are located in the habitable zone, where conditions may allow for liquid water and, potentially, life.
Black holes can produce sound waves, creating a literal cosmic symphony. These waves are in the form of oscillations or vibrations in the surrounding gas, giving black holes a unique "song."
Elements essential for life, such as carbon, oxygen, and iron, are created in the intense heat and pressure of massive star explosions known as supernovae. These elements are then dispersed into space, eventually forming new stars and planets.
Jupiter's Great Red Spot is a massive storm that has been raging for at least 350 years. It is so large that three Earths could fit within its boundaries. Despite its longevity, the storm's origin and mechanisms are not fully understood.
Large galaxies sometimes devour smaller ones in a process called galactic cannibalism. Our Milky Way is expected to collide with the neighboring Andromeda Galaxy in about 4 billion years.
Auroras, like the Northern Lights, are caused by charged particles from the sun interacting with Earth's magnetic field. On Jupiter, auroras are even more spectacular, creating dancing lights near its poles.
Neptune, an ice giant in our solar system, experiences extreme pressure and temperatures. Scientists believe that within Neptune's atmosphere, carbon atoms may be crushed into diamonds, causing a "diamond rain" to fall.
