It was Aug. 14, 2017, just one week before the Moon would cross paths with the Sun and Earth, casting its shadow across the United States.

Measuring Solar Energy Input to Earth

We live on a solar-powered planet. As we wake up in the morning, the Sun peeks over the horizon to shed light on us, blanket us with warmth and provide cues to start our day.

At any given moment, as many as 10 million wild jets of solar material burst from the sun's surface.

ALMA Reveals The Sun in New Light

New images from the Atacama Large Millimeter/submillimeter Array (ALMA) reveal stunning details of our Sun, including the dark, contorted center of an evolving sunspot that is nearly twice the diameter of the Earth.

Improved Real-time Views Of The Sun

A groundbreaking new optical device, developed at NJIT's Big Bear Solar Observatory (BBSO) to correct images of the Sun distorted by multiple layers of atmospheric turbulence, is providing scientists with the most precisely detailed, real-time pictures to date of solar activity occurring across vast stretches of the star's surface.

Tracking Waves From Sunspots

While it often seems unvarying from our viewpoint on Earth, the sun is constantly changing. Material courses through not only the star itself, but throughout its expansive atmosphere.

Towering Magnetic Arches On The Sun

Arches of magnetic field lines towered over the sun's edge as a pair of active regions began to rotate into view in this video captured by NASA's Solar Dynamics Observatory on April 5-6, 2016.

This eerie coloured orb is nothing less than the life-giver of the Solar System. It is the Sun, the prodigious nuclear reactor that sits at the heart of our planetary system and supplies our world with all the light and heat needed for us to exist.

SDO Sees An Unraveling Solar Prominence

An elongated solar prominence rose up above the sun's surface and slowly unraveled on Feb. 3, 2016, as seen in this video by NASA's Solar Dynamics Observatory, or SDO.

On March 9, 1989, a huge cloud of solar material exploded from the sun, twisting toward Earth.

Understanding The Magnetic Sun

The surface of the sun writhes and dances.

NASA-Funded Balloon Launches to Study Sun

On Jan. 18, 2016, the GRIPS balloon team sent their instrument soaring towards the stratosphere above Antarctica, suspended underneath a helium-filled, football-field sized scientific balloon.

The geomagnetic storming watch for 30 December has been upgraded to a G3 (Strong), with a G1 (Minor) storming watch still in effect for 31 December.

A Mechanism That halts Solar Eruptions

Among the most feared events in space physics are solar eruptions, massive explosions that hurl millions of tons of plasma gas and radiation into space.

Reviving STEREO-B

On Oct. 1, 2014, NASA mission operations lost communication with one of the two spacecraft of the Solar and Terrestrial Relations Observatory, or STEREO, mission, just as the spacecraft was about to orbit around the other side of the sun.

For scientists studying the impacts of space weather, one of the central mysteries of solar flares.

The Sun demonstrates the potential to superflare, new research into stellar flaring suggests.

Partial Solar Eclipse Seen By Proba-2

ESA's Sun-watching Proba-2 satellite experienced three partial solar eclipses on 13 September 2015.

NASA's Solar Dynamics Observatory, which watches the sun constantly, captured these images of a significant solar flare as seen in the bright flash on the left peaking at 6:11 p.m. EDT on May 5, 2015.

The sun's surface is blisteringly hot at 10,340 degrees Fahrenheit -- but its atmosphere is another 300 times hotter.
