A person who has been vaccinated against COVID-19 will have a slightly different immune response to the coronavirus than someone who was previously infected, researchers say. How long does immunity last—and is it all about antibodies?

Practice making financial decisions – and overcoming common behavioral biases – in this fun but challenging game.

Astronomers estimate that in about 4.5 billion years, the Milky Way and Andromeda galaxies will collide. Here's how it'll happen.

Since its 1990 launch, the Hubble Space Telescope has allowed scientists to peer deep into space and far back in time to understand the diversity of galaxies in our universe.

Straddling the night sky, the Milky Way reminds us of our place in the galaxy we call home. But what shaped this giant spiral of stars and what will be its destiny? NOVA travels back in time to unlock the turbulent story of our cosmic neighborhood.

Green Toad Hemp Farm is the first Black-owned hemp farm in the state of Georgia. Here’s how the farm works to keep its crop below the legal limit for THC.

The chance of a star being born today is much lower than it was in the universe's past. Here's why—and how astronomers predict the age of stars will someday come to an end.

The most massive, luminous stars have the shortest lifetimes. Here's why—and how they burn out.

The sun is our life-giving source of light, heat, and energy, and new discoveries are unraveling its epic history. Join NOVA on a spectacular voyage to discover its place in a grand cycle of birth, death and renewal that makes this the age of stars.

In this five-part series, NOVA delves into the vastness of space to capture moments of high drama when the universe changed forever. State-of-the-art animation gives us astonishing, photorealistic glimpses of the birth of a star in a stellar nursery, the chaos created as two galaxies collide, and the power of a supermassive black hole as it flings a star across space.

A University of Utah study is analyzing the effects that two cannabinoids—psychoactive THC and non-intoxicating CBD—may have on the brain.

Our ancient ancestor Australopithecus likely foraged for termite larvae using tools made from bone. This source of fat could have helped brain development and growth, anthropologists believe.

Unlike mammals—including those we raise to eat—insects can't generate their own body heat. This physiological difference has a major effect on the quantity of resources they need to grow.

From crunchy crickets to nutty fly grubs, NOVA takes a tasty look at insect foods and how they could benefit our health and our warming planet.

Following days of training, the cuttlefish is faced with the decision to strike and devour one of two tempting prey: Will it wait for the live crayfish or immediately strike the shrimp? Its intriguing behavior is challenging our understanding of the origins of intelligence.

Scientists on the most ambitious Arctic research expedition of all time use remote sensing to help determine the volume of the Arctic's sea ice.

A team of scientists explore the skies to learn how the Arctic atmosphere can have global implications.

In Antarctica, scientists have built the largest neutrino detector, which can catch cosmic neutrinos from billions of light-years away.

Join scientists on the biggest Arctic research expedition of all time. Facing hungry polar bears, perilous sea ice cracks, and brutal cold, the team strives to understand the forces that are changing the region—and the world—forever.

Outnumbering atoms a billion to one, neutrinos are the universe’s most common yet most elusive and baffling particle. NOVA joins an international team of neutrino hunters whose discoveries may change our understanding of how the universe works.
