What is Red Shift?

Back

The phenomenon where a star's light is stretched out, making it look red, as it moves away from the observer.

Front

What are absorption lines?

Back

Fingerprints of the elements that indicate the presence of specific elements in a star's spectrum.

Front

What is Gravitational Collapse?

Back

The process where a star's core collapses under its own gravity, leading to a supernova.

Front

What is a Nebula?

Back

A stellar nursery, a cloud of gas and dust where new stars are born.

Front

What type of stars fuse elements at a faster rate?

Back

High mass stars.

Front

What is Stellar Nucleosynthesis?

Back

The process by which elements are formed within stars through nuclear fusion.

Front

What is a Supernova?

Back

An explosion that occurs at the end of a star's life cycle, resulting in a bright burst of light.

Front

What is a Galaxy?

Back

A massive system of stars, stellar remnants, interstellar gas, dust, and dark matter, bound together by gravity.

Front

What is a Black Hole?

Back

A region of space where the gravitational pull is so strong that nothing, not even light, can escape from it.

Front

What is Stellar Parallax?

Back

The apparent shift in position of a nearby star against a distant background star due to Earth's movement.
