In an unprecedented step, researchers crafted a detailed model compatible with the universe’s accelerated expansion.

To explain these observations, they proposed a new kind of energy that is responsible for driving the universe’s accelerated expansion: dark energy. Astrophysicists now believe dark energy makes up ...

Dark energy may be the most mysterious substance ever proposed, but many scientists are certain it exists. Why?

Scientists have identified a strange cosmic relic called Cloud-9 — a starless, gas-filled object dominated by dark matter.

Dark matter makes up most of the mass in galaxies and galaxy clusters. In fact, scientists estimate that ordinary matter makes up only about 5% of the universe, while dark matter makes up about 27%.
