Summary:

• **What is Dark Matter and Dark Energy?** Scientists have discovered that most of the universe is made of invisible things called dark matter and dark energy that we can't see directly. NASA's Roman Space Telescope will help us understand these mysterious invisible parts of the universe by taking pictures of billions of galaxies.

• **How Will Roman Help Us Learn?** The Roman telescope will map out where dark matter is located by studying how its gravity bends light from distant galaxies, similar to how a magnifying glass bends light. By studying these patterns across huge areas of space, scientists can create a map showing where the invisible dark matter is hiding in the universe.
