The Earth's core is hotter than the surface of the Sun.
A teaspoon of a neutron star would weigh about 6 billion tons.
The human body contains trace amounts of gold, enough to fill about 0.2 milligrams.
The coldest temperature ever recorded on Earth was -89.2°C (-128.6°F) at the Soviet Union's Vostok Station in Antarctica.
The study of plants is called botany, while the study of animals is called zoology.
The concept of the periodic table of elements was proposed by Russian chemist Dmitri Mendeleev in 1869.
The dinosaurs roamed the Earth for about 165 million years, whereas humans have been around for only about 200,000 years.
Every element on the periodic table other than hydrogen was formed in the heart of a star through the process of nuclear fusion.

The universe is approximately 13.8 billion years old, according to current scientific estimates based on the Big Bang theory.
The process by which living organisms evolve and change over time is known as evolution, first proposed by Charles Darwin in his book "On the Origin of Species" in 1859.
At the quantum level, particles can exist in multiple states simultaneously, a phenomenon known as superposition.
Black holes are regions of spacetime where gravity is so strong that nothing, not even light, can escape from them.
The Earth's atmosphere is composed of approximately 78% nitrogen, 21% oxygen, and 1% other gases such as argon, carbon dioxide, and water vapor.
The first photograph of a black hole was captured by the Event Horizon Telescope in April 2019, providing groundbreaking insights into these enigmatic cosmic objects.
