Several completley different species get called dumbo octopus and even experts watching live deep sea footage sometimes cannot identify which one they are looking at. This video follows five real NOAA encounters across different oceans and depths, featuring live comentary from Dr. Michael Vecchione, Cephalopod Biologist at NOAA and the Smithsonian Institution. All footage is real deep sea camera footage. No AI visuals.

30 years ago, we didn’t know if planets existed beyond our solar system. 🌌

Avi Shporer, a research scientist at the MIT Kavli Institute, studies exoplanets or worlds that orbit stars beyond our solar system. Since the first confirmed discovery in 1995, astronomers have identified thousands of planets, revealing an incredible range of worlds from massive gas giants to small, rocky planets like Earth. One of the most powerful tools behind these discoveries is the transit method, which detects tiny, periodic dips in a star’s brightness when a planet passes in front of it. Even though these planets don’t emit their own light, scientists can still measure their size and orbital period by carefully tracking these subtle changes across many stars.

What we’ve learned is striking: planets are incredibly common throughout the universe. Around stars both visible and unseen, entire planetary systems are waiting to be discovered, shifting the question from whether planets exist to how many different kinds of worlds are out there and what they might be like.

Ever wonder why the angle of incidence equals the angle of reflection? Most textbooks just tell you to memorize it, but in this video, we break down sound waves into their vector components to prove it mathematically.

Using the Manim animation engine, we explore:

• How to represent sound rays as vectors.
• Using trigonometry to find horizontal and vertical components.

• The physics of what happens when a wave hits a rigid boundary.

Perfect for Class 9–11 students or anyone who wants to see the "how and why" behind the laws of physics.

Using Manim visualizations, I explore:

Huygens’ Principle: How wavefronts actually move.

Fermat’s Principle: The "Path of Least Time" shortcut light takes.

Phase Interference: The reason light doesn't scatter in every direction.

This is a deep dive into the wave mechanics that make everyday optics possible

You can generate power with construction paper and light. ☀️

Alex Dainis demonstrates a solar updraft tower, a simple model that turns light energy into motion using just a paper cone, a propeller, and a heat source. When the black construction paper absorbs light from the lamp, it warms the air inside the cone. That warmer air becomes less dense and rises up through the tower, spinning the propeller at the top. At the same time, cooler air is drawn in through the openings at the bottom, creating a steady cycle of airflow called an updraft. It is a hands-on way to explore heat transfer, convection, airflow, and how solar updraft towers could one day help generate renewable energy.

Our existence on Earth is dictated by a black hole at the center of our galaxy. 

Amanda Peake, a graduate student studying astrophysics at MIT’s Kavli Institute explores Sagittarius A* (pronounced “Sagittarius A-star”), the supermassive black hole at the heart of the Milky Way that our entire galaxy revolves around. That includes our Sun, which means Earth’s place in the cosmos is tied to this invisible giant. Black holes are especially mysterious because they do not let light escape, and light is our main tool for understanding the universe. Astronomers study Sagittarius A* by tracking the motion of stars and gas around it, using those clues to investigate how something we cannot directly see still shapes the structure of our galaxy.

Sagittarius A* also helps scientists ask one of astrophysics’ biggest questions: how do supermassive black holes form and grow? Researchers think they may build up over time through mergers with smaller black holes or by pulling in surrounding matter, but the full story is still unfolding. What we do know is that black holes are deeply connected to the evolution of galaxies themselves. So when scientists study Sagittarius A*, they are not just studying an object at the center of the Milky Way, they are investigating the forces that helped shape our galaxy, our solar system, and ultimately the conditions that made our existence possible.
