Stardust left behind from the dawn of our solar system has allowed scientists to estimate the Sun took between 10 and 20 million years to form. While there is consensus the Sun formed about 4.6 ...

"We are building arguably the most complex machine ever designed," confided Laban Coblentz. The task at hand is to demonstrate the feasibility of harnessing nuclear fusion - the same reaction powering ...

Today, we know that the sun, along with all other stars, is powered by a reaction called nuclear fusion. If nuclear fusion can be replicated on earth, it could provide virtually limitless clean, safe ...

Have you ever wondered how long it took our sun to form in its stellar nursery? An international collaboration of scientists ...

A star like the Sun is at equilibrium - gravity tends to pull it inwards, and radiation pressure from the nuclear reactions tends to expand it outwards. In other words, the gravitational collapse ...

If we figure out how to harness this effectively and efficiently, this is it. This is the end. This is the solution,” an expert tells us.

There are a number of different nuclear fusion reactions happening in the Sun. The simplest is when four hydrogen nuclei become one helium nuclei.

This releases more neutrons, which continue colliding with other atoms, setting off a nuclear chain reaction ... Fusion is the process that powers the Sun and stars. It is the opposite process ...

China's HL-3 tokamak, a leading "artificial sun" device, now features a digital twin system for real-time monitoring.
