The Sun

Both events show the star releasing huge amounts of energy.

Prince Harry's upcoming memoir "Spare" will tell his life story and the title suggests he may have reason to return to the scandals as well the triumphs.

The smiley face pattern, which is the result of holes in the sun's atmosphere, makes the star look pumpkin-like ahead of Halloween.

The shimmering lights are not just stunning to see—they can teach scientists about the sun's ferocious outbursts.

A coronal mass ejection looks set to graze the planet, adding to a geomagnetic storm forecast for October 1.

The question has sparked a fiery Twitter debate over the true color of Earth's closest star. Even astronaut Scott Kelly weighed in.

Scientists have discovered a sunspot on the back of the sun using helioseismology—the study of the solar soundwaves.

The U.S. Space Weather Prediction Center has upgraded its geomagnetic storm watch from moderate to strong as a group of CMEs approaches.

Scientists can detect far-side sunspots and other hidden solar activity using a technique known as helioseismology.

Some 35 percent of Russians incorrectly think the sun orbits around Earth, rather than the other way around.

Sunspots, caused by the sun's tangled magnetic field, can eject solar material towards Earth resulting in geomagnetic storms.

The structure is a solar prominence—a huge loop of plasma that can be tens of times larger than the Earth.

The minor storm will be caused by a high-speed stream of particles launched from the sun through a "hole" in its atmosphere.

In June, Mercury, Venus, Mars, Jupiter and Saturn will all be visible in the sky in the same order as they orbit the sun—for the first time in 18 years.

The Northern Hemisphere's summer solstice has been marked for thousands of years by people in different parts of the world.

The June solstice marks the beginning of the Northern Hemisphere's summer in astronomical terms.

Photographers captured images of last night's full moon above the Manhattan skyline, the Hagia Sophia mosque, and the Mauna Loa volcano, among other locations.

Meghan Markle's parenting was called into question on a British newspaper website—even as Kate Middleton was defended over Prince Louis' cheeky behaviour.

The sun is starting to get more active as it moves out of a solar minimum and approaches a solar maximum.

Space weather can interfere with life on Earth as well as technological infrastructure in space and on the ground.

Space weather can have an impact on our planet, interfering with life and our technological infrastructure. But can we predict it?

While the Earth's magnetic field largely protects us from radiation and charged particles from the sun, space weather phenomena can impact our planet.

Astronomers say they're close to solving a years-old solar mystery after an up-to-date assessment of the sun's chemical make-up.

The "Late Late Show" host called the prince "incredibly brave" for his royal exit, saying "it's all right to think whatever you think about somebody."

"If Earth were the size of a nickel, Jupiter would be about as big as a basketball," says NASA.

The group of dark blots on the sun's surface are areas of intense solar activity that could flare towards our planet.

Solar activity is set to become more frequent in the coming years as the sun's 11-year solar cycle is yet to reach its peak, which is measured by the number of observed sunspots.

Solar interference with Earth's magnetic field may spark northern lights over Alaska and Canada.

Had the explosion occurred today, it would have been "catastrophic" for satellites, aircraft, and computers, said scientists.

New devices may have the ability to generate the high-temperature conditions needed to create plasma and initiate fusion, offering a pathway to fusion power.
