Big Bang theory
A theory that claims the universe was created more than 13 billion years ago by a massive expansion of space.
Two stars circle around a shared gravitational center.
The core of a collapsing star, whose gravity is so strong that nothing, not even light, can escape.

A named group of stars that make a pattern in the sky.
A crater is a bowl-shaped depression or hollowed-out area caused by a meteorite, volcanic activity, or an explosion.
A crescent shape is a sign or emblem used to represent the first quarter lunar phase or, more broadly, the moon itself.
This stuff, which cannot be seen but can be detected by its gravitational effect, makes up the vast majority of the cosmos.
A small planet-like object that does not fulfill the definition of a planet. Dwarf planets include Pluto, Eris, and Ceres.
With only a few million stars, it is the most common form of the galaxy in the universe.
An astronomical event occurs when an astronomical object or spacecraft becomes momentarily hidden, either by passing into another body’s shadow or by another body passing between it and the viewer.
A planet that is not part of Earth’s solar system and revolves around a star.
A quick explosion of energy is emitted by a star such as a sun.
The sun, Earth, and moon create a line when the moon has advanced 180 degrees from its new moon position. The moon’s disc is as near to being entirely illuminated by the sun as it can go.
A galaxy is a massive gathering of stars that spans billions of light-years. Galaxies usually form spiral or oval shapes.
They are enormous planets, sometimes known as failed stars, primarily composed of hydrogen and helium. Jupiter, Saturn, Uranus, and Neptune are all gas giants.
A densely packed spherical group of ancient stars in a galaxy’s outer regions.
Dwarf satellite galaxies surround a giant spiral galaxy. Hypergalaxies include the Milky Way and Andromeda.
Planets in our solar system are located between the sun and the Earth. Mercury and Venus are examples of planets in this category.
The region of space between galaxies.
High-velocity winds that blow in the highest levels of the Earth’s atmosphere and influence weather.
One can find many comets in this region of our solar system beyond Neptune’s orbit. Pluto is one of the most massive planets in this belt.
The maximum distance that light may travel in a single year. Light years is how space distance is measured. One light-year is approximately 9.5 trillion kilometers long.
A phenomenon created by the Earth passing between the sun and a full moon, casting a shadow on the moon.
A space rock that enters the Earth’s atmosphere and burns away as a bright streak. It’s also known as a shooting star.
Our solar system and hundreds of billions of stars are housed in this spiral-shaped galaxy. It can be seen as a brilliant band across the sky with the naked eye.
A solar system astronomical body that orbits a planet, dwarf planet, or other body.
This vast cloud of dust and gas in space contains the raw materials from which stars are formed.
A star burns brilliantly for a few months after a nuclear explosion before reverting to its original state.
A celestial object’s curving journey around a star, moon, or planet.
A visible shift in the position of a celestial object when viewed from two different angles. Scientists use it to calculate the distances between stars and the Earth.
When the Earth passes between the sun and the moon, the three celestial bodies do not make a straight line in space, resulting in a partial lunar eclipse.
