Since 1958, the National Aeronautics and Space Administration has brought the mysteries of the cosmos down to Earth, inspiring millions across the world to set their eyes on the final frontier.
Hours of research by our editors, distilled into minutes of clarity.
For the first time, we have clear images of the sun’s mysterious south pole. Captured in March 2025, by ESA and NASA’s Solar Orbiter, this footage reveals magnetic chaos that could unlock answers about solar storms, the sun’s strange 11-year cycle, and why its atmosphere is hotter than its surface.
Lagrange Points are special locations where gravitational forces let spacecraft "park" without constant course corrections, making them ideal for science missions. NASA’s James Webb Telescope uses Lagrange Point 2 to stay aligned with Earth while orbiting the Sun.
The field incorporates observational missions to find and classify exoplanets—planets orbiting stars besides the sun—the probing of Earth's most extreme environments to learn what conditions allow life to exist, and theoretical and lab work to identify and analyze potential biochemical signatures.
Decades in the making, JWST is designed to study the universe in infrared light, allowing it to see through cosmic dust and observe ancient galaxies, star formation, and potentially life-supporting exoplanets. The Webb will orbit the sun at a stable point 1.5 million kilometers from Earth.
To peer into the universe’s earliest moments, the Webb had to solve several immense engineering challenges: deploying a massive sun shield, surviving extreme cold, and stabilizing ultra-sensitive instruments. The telescope’s mirrors can adjust themselves in steps 10,000 times smaller than a human hair.
The Webb team has stationed its mammoth observatory in solar orbit—and brought its instruments below 40 kelvins (minus 233 ºC). Remarkably, most of the cooling has been done passively, by shielding the telescope from the sun and letting physics take care of the rest.
Established in 2016, the PDCO characterizes and tracks asteroids and comets passing within 30 million miles of Earth. Over 39,000 near-Earth asteroids have been discovered, though estimates point to about 14,000 more such objects left to be found.
The space shuttle program was initiated by President Richard Nixon in 1972, and its first launch into space came in 1981. At the time, the spaceplane was the world's most complex aircraft, featuring the most sophisticated heat shield in history. The project sought to create a permanent human presence in space for the first time. This series explores everything related to the space shuttle.
This archive includes the many steps it took to put together each Voyager probe. Photos focus on individual parts, like the 8-track tape deck, the large dish-shaped antenna, and its long arm magnetometer boom.
This 3D solar system visualization displays the positions of known asteroids, comets, and spacecraft involved in asteroid studies. Major asteroids include additional details, including orbital trajectories and discovery dates.
Since the time our ancient human relatives began using stone tools to perform tasks, humans have harnessed scientific knowledge and new technologies to advance our ability to feed ourselves, increase our health, expand the boundaries of our knowledge, and much more. From artificial intelligence and quantum computing, to optimizing the human body in pursuit of a long and healthy life, and much more—learn about these topics and more with our smart-but-digestible overviews and expert-curated resources.
