All plants get energy from the sun, but the giant hogweed gets another, dangerous superpower from the sun's light: the ability to burn skin with its sap.

Seasonal illnesses from infectious diseases aren’t a new concept, but a few decades ago public health experts began to notice the same behavior in some non-infectious diseases like breast cancer. These patterns have helped us learn a lot...

Nina Jablonski says that differing skin colors are simply our bodies' adaptation to varied climates and levels of UV exposure. Charles Darwin disagreed with this theory, but she explains, that's because he did not have access to NASA.

DNA damage doesn't just happen in the summer, but does that really mean we should wear sunscreen in the cloudy and chilly months?

Look alive, you! Today we’re diving into the science behind dark circles under your eyes, and all the things that might cause them – tiredness included.

In this video Paul Andersen explains how stratospheric ozone protects humans from ultraviolet light. He explains how stratospheric ozone is formed when diatomic oxygen absorbs an ultraviolet photon and is split into two free oxygen...

The Envy Sat satellite, launched in 2002, is a powerful tool for monitoring the Earth's oceans, land ice caps, and atmosphere. It specifically focuses on studying the ozone layer and its seasonal gaps that allow higher levels of...

This video highlights the ongoing threat to the Earth's ozone layer due to the impact of man-made chlorofluorocarbons (CFCs). It explains how the depletion of ozone, particularly above Antarctica, is monitored and tracked by scientists...

Everyday we experience weather. This interesting series of programs helps students understand the factors that contribute to weather formation. Real-life examples enable students to appreciate the different aspects of weather....

In this video, we learn about how sunscreen works to protect our skin from the sun's rays. It explains the difference between sunscreens and sunblocks, and how they filter or reflect the light to prevent it from burning the skin....

A news feature from NASA’s SOFIA mission originally posted on August 16, 2016.

Learn about the two main layers of the atmosphere: the troposphere and the stratosphere. The troposphere is full of weather and ‘bad’ ozone, and above that, is the stratosphere, where ‘good’ ozone protects us against dangerous UV light....

The 3 simple ingredients of sun, air and water lead to every type of weather on Earth. The atmosphere is constantly trying to balance heat from the sun with water vapor and air to create a dynamic planet. The unique properties of the...

The video discusses the concept of light as a type of electromagnetic radiation and explains the different types of radiations in the electromagnetic spectrum based on their wavelength, frequency, and energy. It also highlights the...

Nebulae get their name from the Latin word for cloud, but they're very different than the clouds we see on Earth. Learn what causes these space clouds and about different types of nebulae.

In this lecture video, the different types of electromagnetic waves are examined, and their uses and applications are explored. The video begins with an overview of the electromagnetic spectrum, starting with gamma rays and ending with...

Through telescopic video and photos combined with animated graphics, students will learn about the layers of the sun and its effects on earth, the moon and all the objects in our solar system and the universe.

Students will learn about the different layers of the atmosphere. The changes in the atmosphere are explained using examples of contemporary environmental conditions brought about by human behavior. The oxygen cycle and the carbon cycle...
