Do you find it hard to imagine the vastness of the Solar System? This video shows how to use strings to make a scale model of the distances from the planets to the Sun and helps gain a better understanding of interplanetary distances....

👉 Learn how to solve the word problems with trigonometry. Word problems involving angles, including but not limited to: bearings, angle of elevations and depressions, triangles problems etc are solved using trigonometry. To be able to...

An explanation and model illustrating that differences in the apparent brightness of the sun compared to other stars are due to their relative distances from the Earth. Using the power of storytelling and cutting-edge technology learners...

Earth has seasons, but what about the rest of the planets in the solar system? Let’s take a tour from Mercury to Pluto and see what seasons would be like on all our planetary neighbors. Bring a sweater!

Scientists have spotted a galaxy from the early origins of the universe, and found evidence to support the existence of a 9th planet in our solar system.

2016 was a lot of things, but for astronomers, it meant the discovery of some of the farthest, faintest, and youngest objects in the universe we've seen yet.

Planets of the Solar System describes each planet’s movement, distance, size, and composition in relation to the sun.

NASA's Dawn spacecraft is currently on its way to the asteroid belt where it will eventually meet with Ceres, its largest celestial body. The dwarf planet has an average diameter of about 950 km (590 miles). Dawn captured the first image...

Scheduled to launch in the mid-2020s, the Wide Field Infrared Survey Telescope (WFIRST) will function as Hubble’s wide-eyed cousin. While just as sensitive as Hubble's cameras, WFIRST's 300-megapixel Wide Field...

This video examines details relating to the planets Uranus, Neptune and their moons. This video also looks at the dwarf planet Pluto and its moons, as well as comet formation in Kuiper Belt and Oort Cloud.

From its vantage point high above Earth’s atmosphere, NASA’s Hubble Space Telescope has completed its annual grand tour of the outer solar system – returning crisp images that are almost as good as earlier snapshots from...

Learn about Rigel -- one of the brightest stars in the universe -- with this Stars Song by KLT!

How big is our Universe? Travel from Earth through the Solar System, past our Galaxy, to the Universe beyond. Physics - Universe - Learning Points. The Universe is constantly expanding. The Universe is already billions of light years...

The video provides an overview of Earth and its characteristics. It describes the shape of the planet as a sphere and its distance from the sun, which allows for moderate temperatures and the ability to support life. The video...

This video is a review of the topics covered in the Planets series. The video is an educational presentation about the shape of the Earth, its distance from the sun, and its rotation on its axis. It also explores the planets in our solar...

Hydrothermal vents are some of the most extreme environments on the planet. But in 2000, scientists discovered a vent unlike any other, one that spews white smoke and is 10 times older. And some think it may help us understand how all...

Since November of 2000, there have always been people on board the International Space Station. That’s nearly 20 straight years of humans living in space! But the ISS isn’t just the world’s coolest playground, it’s also a...

There are many planets in the universe, but very few of them have qualities to support life Taking one celestial body at a time and determining whether it supports life would be slow and inefficient. So, astronomers look for certain...

The Milky way galaxy is composed of up to 400 billion stars, and at least that many planets. Our star, the sun is one of those billions, about a third to halfway out from the galactic center....

Remember those old space movies where spaceships had to maneuver through a bunch of asteroids scattered around and blocking the path of the ship? Well, that's not really true. The asteroid belt contains asteroids which are so far apart...
