Low-E windows have reduced the amount of energy required to heat and cool our buildings, a critical step in fighting climate change. But new research suggests we've lost something beneficial in the process.

SOFIA or The Stratospheric Observatory for Infrared Astronomy is coming to an end, but let's look back on some of the amazing discoveries of this flying telescope.

The Most Unbelievable Image Ever Captured by Hubble Space Telescope

Why are trees and other plants green? Seems like a simple question. But the answer is full of surprises. Using a special camera that can pick up light just beyond the visible range, into the near-infrared, you’ll get to see trees like...

In this video Paul Andersen explains how the greenhouse effect and greenhouse gases keep our planet warm enough to be habitable. He explains how greenhouse gases keep heat closer to the surface. He finally shows how increases in...

The James Webb Space Telescope has launched! But it was a very long road to get to this point, and we’ve been following the progress for a decade!

In a series of mind-bending demos, inventor Mary Lou Jepsen shows how we can use red light to see and potentially stimulate what's inside our bodies and brains. Taking us to the edge of optical physics, Jepsen unveils new technologies...

You've probably heard that carbon dioxide is warming the Earth. But how exactly is it doing it? Lieven Scheire uses a rainbow, a light bulb and a bit of quantum physics to describe the science behind global warming.

This week scientists invented futuristic technologies that sound made up by Hollywood’s spy movies, and we might be able to have infrared supervision without goggles...soon.

This video is about how life arose and what its main function or purpose in the universe seems to be. Thanks to Sean Carroll for collaborating on it!

There are creatures who get some super important and recognizable part of their biology from their diets.

The telescopes of tomorrow will see in infrared and ultraviolet. They will peer through space and scan across time. They will allow us to find new supernovae, spot potentially hazardous asteroids, better understand dark energy and peer...

Each of these contestants has won against the other on Quiz Show before. But this time, we will truly find out who is the best!

James Webb wouldn’t be equipped to look in the infrared if not for the previous missions that have allowed us to see the universe in wavelengths that the human eye can’t see!

Astronomers study a lot of gorgeous things, but nebulae might be the most breathtakingly beautiful of them all. Nebulae are clouds of gas and dust in space. They can glow on their own or reflect light from nearby stars. When they glow...

At least some advanced civilizations might be producing tons of waste heat by now. And researchers are looking for them.

According to two new papers, Mars may have gigantic drinkable glaciers and we might have found the reason that galaxies glow.

Thanks to NASA's James Webb Space Telescope (JWST) project and the Space Telescope Science Institute for supporting this video.



This video is about the line between Brown dwarfs and gas giant planets (aka...

You’ve probably heard a lot about how climate change is affecting our planet, but did you know a warming climate also affects objects in space?

2022 is looking like a great year for space exploration! Let's dig into three of the missions that we're really excited to watch unfold!

In this video Paul Andersen explains why light is important in probing matter. Light travels in photons and the energy of individual photons is determined by Planck's equation. Infrared spectroscopy is useful in detecting the...

Some works of art can be worth thousands, even millions, of dollars. But what if you aren't so sure that Van Gogh you just bought to hang over your toilet is the real deal? Luckily, we can use science to sniff out fakes!

Paul Andersen explains how natural selection is a major mechanism in evolution. The video begins with a discussion of Charles Darwin and the details of natural selection. The data of the peppered moth during the industrial revolution...

It's an increasingly common sight in hospitals around the world: a nurse measures our height, weight, blood pressure, and attaches a glowing plastic clip to our finger. Suddenly, a digital screen reads out the oxygen level in our...
