NASA's Dragonfly spacecraft, a rotorcraft the size of a small car, is set to explore Titan, Saturn's largest moon. Rich in organic compounds, Titan offers a rare window into the kinds of chemical conditions that may have existed on Earth long before life began.

Currently, flying faster than the speed of sound over land is prohibited for commercial flights because it creates disruptive sonic booms. NASA's experimental X-59 plane will research how to turn those booms into "sonic thumps," about as loud as a slamming car door. Lead pilot Nils Larson explains how the X-59 could usher in the next era of commercial supersonic flight.

On September 17, 2025, NASA announced that the number of exoplanets, planets outside our solar system, tracked by NASA has reached 6,000. In the three decades since the groundbreaking detection of exoplanet 51 Pegasi b, the first confirmed planet orbiting a Sun-like star, astronomers have concluded that exotic worlds are everywhere.

A steel vacuum chamber 50 stories deep at NASA’s Glenn Research Center lets researchers simulate near-weightlessness by letting test hardware freefall for 5.18 seconds.

From black holes to star clusters, scientists are turning space data into sound with a process called sonification. Dr. Kimberly Arcand, visual scientist with the Harvard-Smithsonian Center for Astrophysics, joins us to explore how data sonification lets more people experience the cosmos and give researchers a new way to interpret science one note at a time.

The Hubble Space Telescope has changed humanity’s understanding of the universe. Now in orbit for 35 years, it remains a remarkable feat of engineering.

Fighting wildland fires by air at night is especially hazardous. NASA’s ACERO Project aims to make firefighting safer, day or night, with drones and smarter airspace management.

IXPE, or the Infrared X-ray Polarimetry Explorer, is NASA’s first space telescope dedicated to studying X-ray polarization from extreme objects like black holes and quasars.

Big or small, we all take risks nearly every day. But how does NASA manage it? Dr. Mary Skow, NASA’s first agency risk management officer, explains.

NASA’s Air Traffic Management-eXploration Project aims to accommodate the growing demand of traditional and emerging aircraft that share the friendly skies.

NASA's SPHEREx mission will map 450 million galaxies like we’ve never seen before.
