NASA's Curious Universe

NASA has a long history of bringing together science, engineering and art. Space exploration is a human endeavor—one that requires creativity. In this special live episode, NASA astronaut Matthew Dominick and comedian and musician Reggie Watts talk flow states, aircraft ejector seats and more. Plus, a new NASA tool that lets you make music from iconic Hubble Space Telescope imagery. 

When it launched in 1990, NASA expected the Hubble Space Telescope to last for about 15 years. Thirty-five years later, Hubble is still showing us the universe as no other telescope can. Go behind the scenes with Morgan Van Arsdall, deputy operations manager for Hubble, on an audio tour of Hubble’s control center. Morgan’s team keeps Hubble operating smoothly, and when something goes wrong, they s...

How did life begin? It’s one of science’s biggest questions, but it’s impossible to answer on Earth, where ancient clues have been buried by the planet’s shifting surface. Instead, scientists are looking beyond our own planet, to asteroids like Bennu, a distant fragment of a lost world. In 2023, NASA’s OSIRIS-REx spacecraft collected a sample of Bennu’s surface and brought it back to Earth. Ever s...

The Moon’s South Pole is a bizarre landscape. Mountain ridges glow in perpetual sunlight while deep craters freeze in billion-year-old shade. Yet hidden in the depths of those shadowed craters, under temperatures almost three times colder than the frostiest day in Antarctica, lurks something familiar–water ice. In the future, that ice could sustain human explorers or be broken apart into hydrogen...

Black holes are mysterious, far away, and can bend the fabric of reality itself—but we're learning more about them all the time. Ronald Gamble, a NASA theoretical astrophysicist, uses math, computer coding, and a dash of creativity to peer inside some of the universe's most extreme objects. We'll explore what it would feel like to get pulled into a black hole and what people get wrong about black...

As climate change drives more frequent and intense tropical cyclones and hurricanes, coastal communities desperately need better tools to predict how bad storms will be and when and where they’ll strike—and to assess the damage afterward. From the air and in space, NASA and NOAA collect critical data as storms roll in. But what happens next? Fly directly into the eye of the storm with daring hurri...

As NASA’s Europa Clipper spacecraft leaves Earth, it carries a message: we, too, are made of water. Europa—one of Jupiter’s moons—is a top candidate to support life, thanks to its ocean of liquid, salty water capped by a layer of ice. Lynnae Quick-Henderson, a planetary scientist at NASA, explains how Clipper will search Europa for the building blocks of life. The mission is also a message in a bo...

The idea of an asteroid from outer space crashing into Earth has captured the imaginations of science fiction directors for decades. But here at NASA, we take potentially hazardous near-Earth objects seriously. We have a planetary defense office that plans for every scenario—we’ve even practiced nudging an asteroid off course with spacecraft. But there are tens of thousands of objects in near-Eart...

On April 8, 2024, North America experienced its last total solar eclipse until the 2040s. As the Moon’s shadow fell across the U.S., NASA sent Curious Universe producers out into the field across the path of totality to talk to space nerds and eclipse scientists. In this special bonus episode of our Sun Series, we’ll relive the special day together.

For the first time, a NASA spacecraft is flying through the Sun's atmosphere. Nour Raouafi, project scientist for Parker Solar Probe, explains why the Sun's corona is the source of one of the biggest mysteries in all of space science. So, what does it take to build a probe that can touch the Sun—including surviving temperatures of 2,500 degrees Fahrenheit and barreling through sudden eruptions of...

From Earth, the Sun can seem steady and predictable. But when you look at our star close up, there’s a lot going on. Go behind the scenes with NASA’s Moon to Mars Space Weather Analysis Office, a team monitoring space weather—eruptions of radiation and plasma from the Sun that can wreak havoc on spacecraft and pose dangers to astronauts. We’ll also revisit the most powerful geomagnetic storm on re...
