How the Universe Works

Nightmares Of Neutron Stars. Neutron stars are violent phenomena that defy the laws of physics. New discoveries reveal they have the power to destroy planets and even other stars.

When Supernovas Strike. Supernovas are the violent death of giant stars. New discoveries reveal how these events create the elements that are essential to all life in the universe.

Twin Suns: The Alien Mysteries. Half of the star systems in our galaxy have two stars, possibly creating habitats for alien life. Here, binary stars fling entire worlds into space.

Uranus & Neptune: Rise Of The Ice Giants. New research shows the migration of ice planets may have helped start life on Earth, and stopped it being destroyed. How are they so vital?

The Quasar Enigma. Quasars are the brightest objects in space, powered by black holes, and the most mysterious. How do they shape the universe and ultimately aid in its destruction?

Cassini's Final Secrets. For 20 years NASA's Cassini spacecraft revealed Saturn's strange secrets until it vaporized in its atmosphere. Now, fresh data points to new discoveries.

When NASA Met Jupiter. NASA's Juno probe is unlocking Jupiter's secrets, answering mysteries and gathering data. Scientists and experts explain the importance of this mission.

NASA's Journey To Mars. Manned missions to Mars are the next frontier of human exploration and NASA wants to put boots on the Red Planet by 2035. But, is it mission impossible?

The Interstellar Mysteries. Interstellar space is the space between the universe's stars. New discoveries reveal that it's not empty and unremarkable as previously thought.

Did The Big Bang Really Happen?. New discoveries lead scientists to question if the Big Bang really happened. They investigate if it was the start of many multiverses.
