Nasa sun pictures

The elemental composition of the Sun's hot atmosphere known as the 'corona' is strongly linked to the 11-year solar magnetic activity cycle, a team of scientists from UCL, George Mason University and Naval Research Laboratory has revealed for the first time.

The $850 million Solar Dynamics Observatory may help scientists find the causes of solar weather events that disrupt technologies on Earth. Here are some of the latest images from the new observatory.

The Sun is the star at the heart of our solar system. Its gravity holds the solar system together, keeping everything – from the biggest planets to the smallest bits of debris – in its orbit.

This view from the Apollo 11 spacecraft shows the Earth rising above the Moon's horizon in July 1969.

Asteroids, rogue planets, or being swallowed by the sun are just a few of the ways life on Earth could meet its ultimate demise.

when sun and moon finally meet.

Is there a middle ground between thousands and billions of years? Can the earth be hundreds of thousands of years old?

On the night 175 years ago on Sept. 23-24, 1846, astronomers discovered Neptune, the eighth planet orbiting our Sun.

Strangely, the sun showed no sunspots at the time the photo was taken.
