In this video lecture, the topic of infrared radiation is explained in relation to how it affects the temperature of a body. The video presents a graph representing how the energy emitted per unit area per second, or the intensity of...

Beyond molecules and atoms, how far down can we see below the wavelength of visible light? What is the smallest possible scale in the universe?

How can you use an infrared camera to see through walls? To inspect the scene of a crime? To catch a thief in hiding?! This cool device attaches to your smartphone and has an infrared/visible light camera combo that allows you to see the...

This is a lecture video on the topic of wavelength and color. The video focuses on the visible light portion of the electromagnetic spectrum, which can be split into different colors. The video explains the relationship between...

The mythic hunter Orion, son of the sea-god Poseidon, was himself mortal, but his godly lineage enabled impossible heroic feats, earning him a place in the night sky as a constellation. NASA has developed its own Orion, a hunter for...

What do night vision, thermal imaging and remote controls have in common? This animated series of short videos acts as a video glossary to define specific scientific terms or concepts in a fun, easy to understand way. In each episode...

NASA Chief Scientist Jim Green sits down with solar scientist Alex Young to discuss the Sun’s powerful explosions.

Finding black rocks in the darkness of space isn’t easy, but new methods could help spot them all.

Infrared can be divided into three separate categories - near, mid, and far, and even though we can't see it, in some cases we can detect it. Many things, including people and planets, emit infrared. We also use it to transmit...

This video provides a clear and concise explanation of how rainbows are formed through the reflection, refraction, and dispersion of sunlight by water droplets in the atmosphere. It also explores different types of rainbows, such as...

NASA's Swift satellite has acquired the highest-resolution view of the neighboring spiral galaxy M31. Also known as the Andromeda Galaxy, M31 is the largest and closest such galaxy to our own. It's more than 220,000 light-years across...

This video explains how black lights work and their various applications. Black lights emit long wave ultraviolet light, which is invisible to the human eye but causes certain objects, like phosphors, to glow.

NASA’s Nancy Grace Roman Space Telescope will be able to explore even more cosmic questions, thanks to a new near-infrared filter. The upgrade will allow the observatory to see longer wavelengths of light, opening...

The Hubble Space Telescope has been revealing the secrets of the universe for over 30 years, but it turns out Hubble has some secrets of its own!



The question is: What are forming in...

Begin a tour of the Hubble control center in the lobby, where you will learn about the orbiting spacecraft. This is part 1 of 5 of a 360-degree, virtual tour of the Hubble Space Telescope’s home for mission operations, the...

A team of astrophysicists has created a simulated image that shows how the Nancy Grace Roman Space Telescope could conduct a mega-exposure similar to but far larger than Hubble’s celebrated Ultra-Deep Field...

This video is a lecture on the colors of opaque objects and how light interacts with different surfaces to define the color of an object. It explains how white light is a combination of all visible colors and that surfaces with color...

In this video, we learn about how we perceive colors, including the beloved color pink. While pink is not part of the visible light spectrum, our eyes and brain work together to interpret the color pink from the light bouncing off...

The video is a lecture on filters and how they work. It discusses how white light is a combination of all visible wavelengths and how filters are materials that are transparent and only permit certain wavelengths of light to transmit...

A team of astronomers at The Ohio State University watched a star disappear and possibly become a black hole. Instead of becoming a black hole through the expected process of a supernova, the black hole candidate formed...

The world’s largest, most powerful telescope was launched into space on Christmas Day - it’s called the 'James Webb Space Telescope' but WHAT IS IT and WHAT WILL IT DISCOVER? I went to the UK's National Space Laboratory (RAL Space) where...

Explore how gemstones get their colors. We learn that gemstones absorb and reflect certain light waves based on their chemical structures, resulting in different colors. Some gemstones are self-colored, while others are colored by...

Every legacy has a compelling origin. The soon-to-be-launched Landsat 9 is the intellectual and technical product of eight generations of Landsat missions, spanning nearly 50 years. Episode One answers the...
