The Universe

Researchers say they have detected remnants of a universe that existed before our own.

The hungry star, known as RW Aur A, is located around 450 light-years from Earth.

Astronomers previously thought these events only occurred around 3 billion years after the Big Bang, but they were happening when the universe was only half that age.

The discs contain gas, dust and even young planets that are still in the process of forming as the building blocks of planetary systems.

The pictures have helped researchers to identify an elusive object, known as an isolated neutron star, outside our own galaxy for the first time.

The strange events were identified by a project set up to investigate dark energy, an unexplained force that scientists think is accelerating the universe's expansion.

Cosmic voids are gaps left behind during the universe's billions of years of expansion.

When massive stars come to the end of their life cycles, they self-destruct in a cataclysmic final explosion.

More than half of these "ultramassive" black holes have a mass 10 billion times greater than the Sun.

The discovery could help scientists work out how fast the universe is expanding.

A new study of distant galaxies confirms the theory that the energy produced by the universe’s stars and galaxies is decreasing over time

Physicist Brian Greene explains why the world is actually kind of like a garden hose.
