How the Universe Works

Cosmologists say there are black holes throughout the Universe, but they've never seen one and it's almost impossible to study them directly.

Dark matter and dark energy are locked in an epic battle for control of the cosmos, and the winner will determine the fate of the universe; new discoveries might reveal which force will emerge victorious.

For twenty years, NASA's Cassini spacecraft revealed the strange secrets of Saturn until it vaporized in its atmosphere in a blaze of glory; but today its legacy lives on, as fresh data from the probe helps scientists make brand-new discoveries.

New discoveries cause astronomers to question if the Big Bang really happened; using the latest science, they investigate if it wasn't just the start of the universe but many mysterious multiverses.

New discoveries have revealed thousands of exoplanets beyond the solar system, and some resemble earth enough that one could be a new home for humanity; with cutting-edge technology, finding the perfect one is the scientific challenge of the age.

Black holes are not the violent monsters people think they are, and new discoveries reveal that they might have been essential to creating stars, giving light, and building the universe itself.

The latest discoveries suggest life beyond this planet; scientists investigate if earth's life began elsewhere in the universe, and whether humans need to evolve to know for sure.

Neutron stars are strange and violent phenomena that defy the laws of physics, and new discoveries reveal that these bizarre nightmares are far more deadly than previously believed, with the power to destroy planets and even other stars.

Nebulas are the strange structures of cosmic gas and dust where stars are born and die, and new discoveries reveal the secrets of these mysterious places.

Our solar system is home to hundreds of strange, tiny worlds called dwarf planets, and new discoveries reveal the secrets of these mysterious places.

Discoveries about interstellar space, the space between the universe's stars, reveal that it's not empty and unremarkable as previously thought, but filled with weird objects and strange phenomena that might hold the darkest secrets of the cosmos.

Mars is infested with robots, orbiting the planet and roaming the Martian surface on a mission to uncover its secrets; now, Perseverance joins this dedicated group of machines to uncover if there is, or was ever, life on the Red Planet.

In a fictional scenario set in 2029, an asteroid hurtling towards Earth at 40,000 mph will reduce New York to ashes; examining the hypothetical, experts weigh in to determine what could happen, and how it might be stopped.

Earth's history is marked by one cosmic disaster after another, forging the path of human evolution; now, experts explore how the Earth has teetered on the verge of destruction.

Dark Matter is thought to be the cosmic glue that holds the universe together, yet the search for it continues to eluded scientists today.

Determining the age of the universe continues to be an elusive endeavor for scientists as their results are conflicting, and without a definitive answer, everything that's known about the cosmos could be completely wrong.

The collision of two supermassive black holes is the most violent event that can occur in the universe; experts explore where a black hole's energy originates and what really happens when the two most powerful objects in the cosmos clash.

With more than 80 moons, Saturn could rank among the most dynamic planetary system in Sol's neighborhood; with its giant underground oceans and protective magnetic fields, experts explore how Saturn's moons offer new insight into the Solar System.

As the two Voyager spacecraft reach interstellar space, experts explore their astonishing discoveries and how their extended operation has transformed into the ultimate mission.

Exploring new discoveries that rewrite the history of the solar system, revealing a complex and violent story that begins with the birth of the sun from the debris of a massive galactic collision to its eventual fate as a lone zombie star.

Scientists use technology to stop an asteroid apocalypse; mankind comes closer to keeping Earth safe from killer space rocks.

Examining the ways the universe could come to an end.

Exploring the real-life Death Stars in the cosmos that could snuff out Earth without much effort; the science of the destructive power behind six of the deadliest stars; vampire stars; supernovas; rogue stars.

Quasars are the brightest and most powerful objects in the universe, and though they have shaped the cosmos, they might ultimately destroy everything that exists.

Star systems with binary stars, once relegated to science-fiction, may actually exist and serve as ideal places for alien life to thrive.
