Alex Young is interviewed about the current solar cycle and what a magnetic flip means for the earth and NASA's study of magnetic fields.

Our Sun releases a constant flow of charged particles & magnetic fields that creates a bubble in space (but not the soapy kind). Beyond the edge of this bubble is interstellar space, now home to the two Voyager spacecraft. Here are five...

Time in Your World explores time as it relates to our everyday lives–time to get up, time for school, lunchtime, bedtime, daytime, nighttime. The program explains how clock hands measure time in hours, minutes, and seconds and how to...

Stars are much bigger and complex than they look from Earth. Learn how they form and how they are classified.

It explains solar energy as renewable source of energy and the working of a solar cooker, solar water heater and solar cell panel.

In this video, the teacher explains the concept of the Earth's rotation and its effect on day and night. They use a toy spinning top as an analogy to demonstrate how the Earth spins on its axis, causing the sun to appear to rise and set....

To observe how winds move high in Earth's atmosphere, scientists sometimes release clouds of barium as tracers to track how the material corkscrews and sweeps around � but scientists have no similar technique to study the turbulent...

Sungrazing comets are a special class of comets that come very close to the sun at their nearest approach, a point called perihelion. To be considered a sungrazer, a comet needs to get within about 850,000 miles from the sun at...

In this video, we discuss the biosynthetic pathway for vitamin D and how vitamin D exerts its functions at the gene expression level. We also explore the clinical affect of statin therapy on vitamin D levels.

Blast off with The Bazillions on a journey of the imagination aboard a SUPER SONIC ROCKET BIKE!

The next total solar eclipse will occur over parts of North America on Monday, April 8, 2024.

What does our planet look like from space? Most are familiar with the beloved images of the blue marble or pale blue dot -- Earth from 18,000 and 3.7 billion miles away, respectively. But closer to home, within the nearest region of...

An unusual eruption on the Sun may offer clues to understanding our star’s mysterious explosions. The new research studied an event named the “Rosetta Stone'' of solar eruptions. Just as the Rosetta Stone was the key to understanding...

A countdown of the top 5 solar discoveries from the Sun-Earth Connection Education Forum. These include the discoveries of sunspots, the solar cycle, the heliosphere, aurora formation, and space weather. Number 4 in the Top 5 Solar...

This live-action video program is about the word revolution. The program is designed to reinforce and support a student's comprehension and retention of the word revolution through use of video footage, photographs, diagrams and...

Scientists have recently gathered some of the strongest evidence to date to explain what makes the sun's outer atmosphere so much hotter than its surface. The new observations show temperatures in the atmosphere so hot that only one...

Scientists believe that the solar system took billions of years to develop! This video gives an overview of solar system basics - its beginnings, gravity, planets orbits.

This video explains how the four seasons - winter, spring, summer, and autumn - are experienced differently depending on where we are located on Earth. It explores the unique characteristics, beauty, and dangers of each season and how...

On July 5, 2017, NASA's Solar Dynamics Observatory watched AR26665, an active region -- an area of intense and complex magnetic fields -- rotate into view on the sun. The satellite continued to track the region as it grew and eventually...

As you know a solar eclipse occurs when the moon is placed between the earth and the sun. But, if the moon takes about 28 days to travel around Earth... Why don’t we see eclipses every month? "Eclipse" comes from the Greek word...

What is OPAL? OPAL (Outer Planet Atmospheres Legacy) is a project to obtain long time baseline observations of the outer planets in order to understand their atmospheric dynamics and evolution as gas giants. The yearly observations from...

The number of sunspots increases and decreases over time in a regular, approximately 11-year cycle, called the sunspot cycle. The exact length of the cycle can vary. It has been as short as eight years and as long as fourteen, but the...
