From roughly 60 miles above the Earth's surface to farther than light has traveled during the entire age of the universe, space has captured human imagination for millennia. Explore the final frontier with the best resources curated from across the internet.
Hours of research by our editors, distilled into minutes of clarity.
Space is vibrant with emissions of light and energy, and traditional observatories usually translate this data into visuals. Now you can hear the sonification of celestial objects, where researchers represent the beauty and power of distant space using different tones and volume, a project meant to provide more resources for the blind and low-vision community.
Quasars form the core of active galaxies where supermassive black holes devour unimaginable amounts of matter. You can see a map of all 1.3 million of these objects with this 3D map. It was assembled with data from the Gaia spacecraft and shows how the spread of dark matter across space matches that described by the Cosmic Microwave Background.
The sun—the giant star at the center of our solar system—is vital to earthly beings. It’s part of our daily life and affects our senses—but can it be heard? Astronomers chime in to answer this question and conclude the sun doesn’t make sounds we can hear on Earth because of the vacuum of space. Learn more about the behaviors of the sun and how sound travels in this fascinating Popular Science article.
We think of all planets as spheres, but do they have to be spheres? To be classified as a planet, an object has to be sufficiently massive to reach a spherical shape through gravity. However, this doesn't mean they're perfectly round; for example, Earth has a slight equatorial bulge caused by centrifugal force from its rotation. Other observed planets feature tear-shaped formations while theorists posit donut-shaped planets. Read more here.
How exactly does the moon move, and why does it move that way? In this ridiculously comprehensive interactive explainer, you can conduct experiments to see how the moon rotates and as it moves around the Earth, while learning how gravity works by controlling the path and speed of different objects. Dive into this beautiful, simple explainer to learn the basics on gravity and the moon.
Curious about the layout of the cosmos? This resource presents a detailed map of our galaxy, the Milky Way. Learn the basic structure and identify prominent global clusters, nebulae, main arms, spurs, and constellations. With numerous different maps and mediums, get oriented with the universe’s configuration and where exactly we fit into it.
NASA's Eyes on the Solar System allows you to track all kinds of objects in space in real time, from observatories like the James Webb Telescope to all manner of comets and asteroids. Zoom in and out, read up on space missions, and see the solar system from a totally new angle with this incredible interactive site. Jump in here.
In the same way that archaeologists excavate and analyze artifacts of human civilization, galactic archaeologists observe the light in the universe to glean lessons on its age, evolution, and more. Learn about this niche area of study with this 10-minute podcast.
On March 2, 2025, Firefly Aerospace landed its Blue Ghost craft on the Moon. The private company then operated the craft for two weeks, conducting surface operations and becoming the first private space company to have a fully successful mission on the Moon. This short video captures pristine, dramatic footage of the mission's successful touchdown.
Take one small step today and experience the historic moon-landing through VR. This video showcases how VR is allowing the public to travel through space through the eyes of those who lived through it.
