NASA was founded in response to early Soviet space achievements

Although starting behind in the Space Race in 1958, NASA became a global leader in humanity's exploration of space with the Apollo program, which placed astronauts on the moon. Since then, it has been responsible for the construction of multiple telescopes, the International Space Station, and development of the Artemis program to return humans to the Moon before eventually reaching Mars.

James Webb Space Telescope aims to unlock secrets of the early universe

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.

The twenty-year effort to design the Webb's optics

Since its located 1 million miles from Earth, the Webb space observatory has to be able to repair itself—no Space Shuttles can be dispatched with astronaut engineers to repair it. That's why over two decades teams reiterated, cross-checked, and hyper-optimized the Webb's observing surface. Their efforts produced the world's largest space-based optical surface that is peering billions of years back in time. Learn the wild engineering of the telescope here.

The aesthetics of the James Webb images

The highly popular images produced by the James Webb Space Telescope are an artful collaboration between data science and visual designers. The raw data reflects real physical aspects of space, but it arrives without visual representation. Visual experts assign colors to specific wavelengths, crop and orient images in an accessible way, and consider the emotional impact of images as they incorporate design principles into the final product. Learn the fascinating details here.
