Sun

A new study indicates that shockwaves from the young Sun would have caused the planets of our solar system to form at different times.

The Sun is nearly the roundest object ever measured...but why?

Researchers may have discovered a new method to predict solar flares more than a day before they occur.

Super tornadoes on the Sun may one day help scientists develop ways of produce clean, free energy here on Earth.

New research shows that the Moon has a far-reaching influence on the solar wind.

A new study shows how the solar storms of March 8th through 10th dumped enough energy in Earth's upper atmosphere to power every residence in New York City for two years. Studying how the Sun affects the Earth is important in understanding our planet's habitability.

To deal with the faint young Sun paradox, researchers are taking a fresh look at an old idea: that the Sun started out larger and more luminous than we thought.

Roughly 5 billion years from now, the Sun will begin to swell as a red giant. But life on Earth will feel the effects of an aging Sun long before then. What can we do to survive?

A coronal mass ejection from the Sun could deliver a glancing blow to Earth's magnetic field this week.

A new study suggests that scientists may soon be able to predict sunspots before they're visible to the human eye. Sunspots are the starting point for coronal mass ejections - powerful bursts of energy that sometimes hit the Earth.
