From rats to snow, building massive scientific instruments in harsh environments requires money, brilliant engineering, and good old-fashioned human sweat.

With the demands of gravity absent, astronauts must spend hours per day exercising to maintain the muscles they'll still need back on Earth.

Usually new tech brings us closer to understanding more of the universe, but in the field of cosmology, one uncertainty is only getting worse.

How do you launch a rocket from Mars? NASA's jaw-dropping plan involves pitching it in the air and igniting it aloft.

Now that NASA has wrangled a chunk of asteroid back to Earth, a team of scientists is busy photographing, crushing, and even shooting lasers at the dust.

Using new instruments and clever science, the Mars Insight lander left us with incredible new insight into the belly of the red planet.

Earth is surrounded by potential threats like asteroids and comets, but a team of NASA scientists is always on the lookout.

We've sent wheeled rovers and even helicopters to Mars, but to explore its hidden depths, it will take robotic legwork.

The James Webb Space Telescope only launched recently, but scientists are already plotting a planet-hunting telescope that will help find worlds like our own.

Dark matter isn’t visible to the human eye, or even telescopes, but there is an ingenious way to map its presence across the universe.

Lighting is typically more of an afterthought when it comes to space habitats, but as it turns out, it may just be the most important part

Venus is one of the most brutally inhospitable places in our solar system, but many scientists think life could have thrived there at one point. Here's why.

Most missions collect samples and analyze them in situ with relatively basic instruments. This mission takes a totally different approach.

Released months after the space shuttle Challenger disaster in 1986, SpaceCamp disappeared from pop culture despite a standout cast and legendary composer.

Slowing a spacecraft down takes tons of fuel, so scientists are eager to try something different on Venus: slowing down with the help of the planet's atmosphere

NASA has a new program that gathers data from millions of amateur astronomers, and it could be a game-changer for astronomy.

The Vera C. Rubin Observatory houses the world's largest digital camera. Here's how it'll help astronomers explore the cosmos

NASA's 1978 astronaut class was a turning point for the agency, and it set the stage for the more diverse and inclusive space program we have today

Space is full of dangerous cosmic radiation, and in order to send astronauts to Mars, we'll need to protect them from it. Here's how.

NASA doesn't just point a telescope at space and snap a photo. JWST's data needs to be translated from infrared to visible light — then it becomes an image.

Astronomers have been on the hunt for habitable planets outside of our own solar system for decades -- but what exactly counts as habitable?

Now that the James Webb Space Telescope has sent back its first images of deep space, you might be wondering what's coming next. Here's the scoop!

Venus's acidic, high-pressure atmosphere is one of the most inhospitable places in our solar system -- and NASA is building a probe that can withstand it

NASA has been monitoring Earth's sea levels from orbit for over 30 years. Here's why measuring from space is actually easier than doing it terrestrially.

Let's celebrate Earth Day with 24 stunning images of our very special planet, all shot from space.

The James Webb Space Telescope is often called the successor to Hubble, and is built to peer into deep space -- so why is NASA aiming it at Jupiter?
