A region in space where gravity is so strong that nothing, not even light, can escape from it.

The distance that light travels through space in one Earth year, approximately 9.46 trillion kilometers.

A colossal, luminous explosion that marks the violent end of a massive star's life.

A planet that orbits a star outside our solar system in another distant star system.

A gigantic interstellar cloud of gas and dust where new stars and planetary systems are born.

A massive gravitational system consisting of billions of stars, planets, gas, and dark matter bound together.

A rocky, airless remnant left over from the early formation of our solar system, usually orbiting the Sun between Mars and Jupiter.

A cosmic snowball of frozen gases, rock, and dust that warms up when near the Sun, displaying a glowing coma and spectacular tail.

The one-way causal boundary surrounding a black hole where the spacetime escape velocity strictly equals the speed of light in vacuum, preventing any causal signal or matter from escaping outward.

The unseen, mysterious components that constitute approximately 95% of the total cosmic mass-energy budget. Dark matter binds galaxies gravitationally, while dark energy drives the accelerating cosmic expansion.

A hyper-dense, highly magnetized rotating neutron star that sweeps collimated beams of electromagnetic synchrotron radiation across the cosmos like a lighthouse as it spins.

The primordial thermal relic radiation permeating the cosmos, originating 380,000 years after the Big Bang during the epoch of recombination when neutral hydrogen atoms first formed.

The gravitational deflection and magnification of light rays traveling from a distant luminous source through the curved spacetime created by an intervening massive cluster, galaxy, or black hole.

An exceptionally luminous active galactic core fueled by a supermassive black hole accreting gas and dust at relativistic velocities, radiating vast amounts of energy across the spectrum.

A standard unit of astronomical measurement approximately representing the mean orbital distance between the center of Earth and the center of the Sun.
