Let's Talk Space Exploration Resources

One of the greatest hazards that humans in space face is cosmic radiation. Learn what cosmic radiation is, why it's dangerous, and ways that we are looking at protecting humans in deep space.

Astronauts can experience bone loss in space. To understand why, you need to know a bit about how bones are formed and maintained in your body.

Earth is covered in rocks. So are Mercury, Venus, Mars and the Moon. Does that mean the rocky planets are all the same?

Litter isn't just a problem on Earth. When litter ends up in space, it can cause collisions and other consequences for satellites, the International Space Station and even for people on Earth!

In planetary science, astronomers have found planets that orbit other stars, just like Earth orbits the Sun. Some of them might even be able to support life.

In 2019, scientists discovered that our galaxy, the Milky Way, is not the shape they thought it was. How do astronomers use astronomical distance to understand the shapes of galaxies?

Gamma rays might make you think of cancer, harmful radiation or superheroes. But gamma rays have lots of uses: food safety, manufacturing and even medicine!

Physicists are a bit like chefs, except they’re trying to figure out the recipe for the universe.

Learn what quantum mechanics is, the history of its development and the ways we use it today.

Melissa Valdez talks about her exciting work on antimatter at CERN when she was a graduate student at York University.

The life and death of stars form the chemical elements that make up Earth, making stars critical to life as we know it.

Learn about a new material for spacesuits and the engineer who designed it.

Find out how asteroids, space debris, and cosmic radiation can be dangerous, and how to monitor them and protect ourselves from these space hazards.

If an asteroid were to hit the Earth it could be disastrous. Here are some ways we could protect ourselves.

NASA engineers apply kinematics and dynamics to test parachutes designed specifically to help space probes land safely using aerodynamics.

Why do a baseball and a rocket need the same launch speed to get from Earth into space? It has to do with physics and gravitational force.

Canadian astronauts Jeremy Hansen and David Saint-Jacques explain how learning to fly an aircraft prepared them for the challenges of living in space.
