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.

Voyage to discover the sun’s place in a grand cycle of birth, death and renewal.

NOVA Universe Revealed: Age of Stars

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

The saying "live fast, die young" applies to stars, astrophysicist Grant Tremblay says.

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 age of stars is not as enduring as it might seem.

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 the sun’s place in a grand cycle of birth, death and renewal that makes this the age of stars. Witness how stars of every size and color came to populate our universe; how stars stage a dramatic exit when they explode as supernovae, which can outshine an entire galaxy; and how, billions of years in the future, the age of stars will lead ultimately to an age of darkness.

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.

Explore the wonders and mysteries of our galaxy—the giant city of stars we call home.

NOVA Universe Revealed: Milky Way

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

The Milky Way as we know it today is not eternal.

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, from its birth in a whirling disk of clouds and dust to colossal collisions with other galaxies. Finally, peer into the future to watch the Milky Way’s ultimate fate as it collides with the Andromeda galaxy, over 4 billion years from now. (Premiered November 3, 2021)

Exoplanets like OGLE-2005-BLG-390Lb, aka Hoth, seem to defy the logic of our solar system. So scientists needed to rethink the planetary rulebook.

No one predicted that planets like this were even possible.

Yes, There's Really a Frozen Exoplanet named Hoth

Ultra-sensitive telescopes have transformed alien planet-hunting from science fiction into enthralling hard fact. Join NOVA on a visit to exotic worlds orbiting distant suns to answer an age-old question with thrilling new science: are we alone?

Science fiction got some things right: On worlds in binary star systems, there are always two shadows and two sunsets.

What would life be like in a binary star system?

It’s an age-old question: are we alone? Or do other lifeforms and intelligences thrive on worlds far beyond our own? Ultra-sensitive telescopes and dogged detective work are transforming alien planet-hunting from science fiction into hard fact. Join NOVA on a visit to exotic worlds orbiting distant suns, from puffy planets with the density of Styrofoam to thousand-degree, broiling gas giants. Most tantalizing of all are the Super-Earths in the “Goldilocks zone,” just the right distance from their sun to support life, and with one of them signaling life’s essential ingredient, water, in its atmosphere. Are we on the brink of answering that haunting question. (Premiered November 10, 2021)

A supermassive black hole sits at the center of the Milky Way galaxy, scientists believe. Would life as we know it exist without this invisible enigma?

Scientists believe a giant black hole sits at the center of our galaxy.

Take a seat on the ultimate thrill ride to explore nature’s strangest and most powerful objects. Black holes can reshape entire galaxies, warp the fabric of space and time, and may even be the key to unlocking the ultimate nature of reality. A new generation of high-energy telescopes is bringing these invisible voids to light, showing that “supermassives” millions or billions of times larger than our sun lurk at the center of nearly every galaxy, including our own. But what happens if you stray too close to one? And what lies beyond the black hole’s abyss? If nothing can ever escape it, is that the end of the story? Or could they be a portal to another dimension—or another universe, full of black holes? (Premiered November 17, 2021)

Feast your eyes on one of the most important images in all of cosmology: a picture of the first light from the Big Bang.

Scientists now have a detailed image of the entire universe in its infancy.

Scientists Capture the First Light from the Big Bang

The Big Bang is when the cosmos started and time itself began. With stunning animation based on space telescope images, NOVA winds back the ages to discover new clues about this ultimate genesis and what happened in the universe’s first few seconds.

The Big Bang was less of an explosion than a transformation of energy into matter.

Energy transformed into matter during the Big Bang.

Was the Big Bang an Explosion or Something Else?

The Big Bang is when many think the universe started and time itself began. But what clues can we discover about this ultimate genesis of everything? And can we ever know what existed before the Universe’s birthday? With stunning animation based on space telescope images, NOVA explores infant galaxies filled with violent blue stars that formed just a few hundred million years after the Big Bang. Before that—before the coming of visible light itself—stretch the “cosmic Dark Ages.” But scientists haven’t stopped there; instead, they’ve come up with an incredible theory for what happened billionths of a billionth of a second from the universe’s birth. If they’re right, we’re on the brink of understanding more than we could ever have hoped about our cosmic origins.

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 so violently that it’s still traveling 10 million years later. NOVA even takes viewers back on the ultimate time travel voyage, to witness the birth of space and time itself. Informed by huge advances in scientific understanding, the series brings us face-to-face with the most surprising characters in the cosmos and reveals how their fates are intertwined with our own.
