A diffuse nebula situated south of Orion's Belt. It's one of the brightest nebulae, visible to the naked eye in the night sky.

The Sun is a G-type main-sequence star at the center of the Solar System. It's the most important source of energy for life on Earth.

Second planet from the Sun, similar in structure but hotter than Earth. Its thick atmosphere traps heat in a runaway greenhouse effect.

The largest object in the asteroid belt and the only dwarf planet located in the inner Solar System. It was the first asteroid to be discovered.

A highly magnetized, rotating neutron star that emits beams of electromagnetic radiation. This radiation can be observed when the beam points toward Earth.

A spiral galaxy approximately 2.537 million light-years from Earth. It is the nearest spiral galaxy to the Milky Way and on a collision course with it.

The galaxy that contains our Solar System, with a bar-shaped core and spiral arms. The Milky Way is part of the Local Group of galaxies.

Originally classified as the ninth planet, Pluto is now considered a dwarf planet in the Kuiper belt. It has five known moons.

Icy bodies that release gas or dust. They are often characterized by their bright comas and long tails when near the Sun.

The explosive death of a star, resulting in a bright, short-lived astronomical event. Elements heavier than iron are created and dispersed during this event.

A type of compact star composed of neutrons resulting from the gravitational collapse of a massive star after a supernova. They are incredibly dense.

The smallest and innermost planet in the Solar System. Mercury has a very thin atmosphere and no moons.

The sixth planet from the Sun, notable for its prominent ring system. Saturn is a gas giant with many moons.

The eighth planet from the Sun, known for its striking blue color. Neptune is an ice giant and has the fastest winds in the Solar System.

The largest planet in the Solar System, known for the Great Red Spot, a giant storm. Jupiter is a gas giant with a strong magnetic field.

The seventh planet from the Sun, distinguished by its tilted rotational axis. Uranus is an ice giant with faint rings.

A region of space located between Mars and Jupiter filled with millions of rocky bodies. It's thought to be remnants from the Solar System's formation.

The fourth planet from the Sun, known for its red color. Mars has polar ice caps and the largest volcano in the Solar System, Olympus Mons.

A region of space where the gravity is so strong that nothing, not even light, can escape from it. The theory of general relativity predicts their existence.
