6 mind-blowing NASA facts about dark matter and dark energy

Scientists first suspected dark matter’s existence 80 years ago.

It was Swiss-American astronomer Fritz Zwicky who noticed galaxies in the Coma cluster moving too fast to stay together.

In the 1970s, Vera Rubin found a similar mystery in spiral galaxies. Stars on the edges moved too fast to stay bound by visible matter, suggesting the presence of an invisible substance.

Dark matter is a mysterious, invisible substance. Its exact nature and particle mass remain unknown, making it difficult to study.

Though invisible, dark matter interacts with normal matter through gravity.

Dark matter shapes the universe. Scientists map it by studying galaxy clusters and their gravitational effects.

Light travels in straight lines, but massive objects like galaxy clusters curve space-time, bending light around them.

By studying dark matter, scientists hope to understand its nature, solving one of the biggest mysteries in modern astronomy.
