This year, NASA returns to the Moon.

In space, humans become weaker. Organs even shift inside the body. Learn about NASA research to combat space-based muscle loss and improve astronauts’ balance.

NASA explores Earth more than any other planet. Take in the view from space with Karen St. Germain, director of NASA’s Earth Science Division.

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 since, scientists have been hard at work studying the fragments of asteroid Bennu. Now, they’re ready to reveal the results—our best look yet at a time capsule from the early solar system that once fostered the ingredients for life.

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 and oxygen to refuel rockets. Join Brett Denevi, Artemis III geology team lead, to learn why NASA plans to land astronauts on the Moon’s South Pole later this decade. Then with Michelle Munk, NASA space technology chief architect, meet the robot Moon landers scouting ahead of Artemis which will drill beneath the regolith and test technologies designed to help future human explorers survive the Pole’s extreme conditions.

Dr. 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—black holes.

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 hurricane hunter pilots, meet meteorologists and data scientists building AI models to improve hurricane prediction, and join the disaster response experts helping cities pinpoint their hardest-hit neighborhoods. Plus, learn how NASA is making data open to everyone—including you, with Transform to Open Science.

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 bottle, bringing a greeting from one ocean world to another. Hear how Ada Limón, the Poet Laureate of the United States, used NASA’s mission as inspiration for her poem “In Praise of Mystery: A Poem for Europa” and why she thinks everyone—even space nerds—should step back and appreciate our connections to the universe and each other.

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-Earth space, and the first step in protecting against potential impacts is spotting, tracking and managing every single one of them. Learn how NASA does just that from Joe Masiero, a scientist on the asteroid survey mission NEOWISE. Then, join friend of the show Latif Nasser, co-host of the podcast Radiolab, to untangle the mystery of a strange space rock that’s not quite a moon but not quite a normal asteroid, either.

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 solar plasma—and live to tell the tale? We'll also go inside the fleet of NASA spacecraft studying the Sun from many angles, including the rescue mission to save a wildly spinning observatory before it became lost in space forever.

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 record, an 1859 event that produced northern lights visible in the tropics and made electrical systems go haywire. This is episode fiof the Sun and Eclipse series from NASA’s Curious Universe, an official NASA podcast.
