Where is the sun in its current 11-year solar cycle? | Space
Solar cycles are not exactly 11 years long; they can range from around nine to 13 years. Stronger solar cycles — those with a higher sunspot peak — tend to be shorter in duration, and
What Is the Solar Cycle? | NASA Space Place – NASA Science for Kids
The Sun''s magnetic field goes through a cycle, called the solar cycle. Every 11 years or so, the Sun''s magnetic field completely flips. This means that the Sun''s north and south poles switch
Solar System
Inside the Sun''s core hydrogen is fused into helium for billions of years, releasing energy which is over even longer periods of time emitted through the Sun''s outer layer, the photosphere. This creates the
The life cycle of a star: How will our Solar System end?
About five billion years from now, the Sun will have reached the end of the main sequence of its lifespan, and will have used up all the hydrogen in its core. With no fusion process to
Explainer: What is the solar cycle?
One of the most striking features of the sun''s activity is what astronomers call the solar cycle. This is an epic rise and fall in the sun''s level of activity that repeats every 11 years or so.
14.1.3: The Solar Cycle
We now know that the Sun is in a perpetual state of change: its surface is a seething, bubbling cauldron of hot gas. Areas that are darker and cooler than the rest of the surface come and go. Vast plumes of
The Lifecycle of the Solar System: From Here to Eternity
Will it go supernova or collapse into a black hole? The answers to these questions are largely speculation for now, but there are some things we do know about how our solar system will
Our Solar System and the Life Cycle of a Star
This section covers the planets in our solar system and the life cycle of stars. The study of our Solar System and the life cycle of stars is key to understanding the fundamental processes that govern the
The Lifecycle of Our Sun
In about 5.4 to 6.4 billion years, the Sun will run out of hydrogen, ending its main sequence phase, and causing drastic changes to the sun and the solar system.
