The temperature in the Sun's core is about 27 million degrees Fahrenheit (15 million degrees Celsius), hot enough to make fusion reactions work perfectly. 5 million gigapascals. Think about this: the ...

The Sun is mostly hydrogen and helium. Its core temperature is 27 million degrees Fahrenheit. The Sun is about 4.6 billion years old. It's a G-type main-sequence star. Key takeaways sponsored by The ...

For thousands of years, humans have worshipped the Sun. Our ancestors built monuments and temples to it, and used it to mark the annual cycle of seasons. For ancient Egyptians, their most important ...

The Sun's transition from the main sequence to the red giant phase is a gradual process, spanning approximately a billion years. This transition begins with a subgiant phase where core hydrogen fusion ...

It’s impossible to forget just how much the sun affects life on our planet. It’s overwhelmingly the source of our light and heat, providing just enough to maintain the delicate climatic balance we ...

A fun nightmare sci-fi scenario is the sun being consumed by a black hole. Fortunately the chance of a black hole randomly wandering into our solar system is pretty tiny. That’s good news. But what if ...

Our Sun, that steady burning ball of gas that has faithfully illuminated Earth for billions of years, is slowly but relentlessly growing brighter. This might sound like good news, but it's actually ...

In a remarkable feat of nanoscale engineering, scientists have developed a microscopic engine that operates at temperatures exceeding the core of the sun. This groundbreaking advancement pushes the ...

An artist’s impression of the far-future sun, swollen to become a red giant star, as seen from a molten Earth landscape. As summer settles in and temperatures climb in the Northern Hemisphere, it’s ...

A tiny, particle-sized engine that runs at temperatures approaching the innermost core of the Sun could open a window into the smallest extremes of thermodynamics. By levitating a single particle of ...

New research suggests that the sun may hold dark matter in its fiery heart, and ghostly particles called neutrinos could lead us to it. When you purchase through links on our site, we may earn an ...
