The sun emitted a significant solar flare, peaking at 1:48 p.m. EDT March 29, 2014, and NASA's Solar Dynamics Observatory captured images of the event. Solar flares are powerful bursts of radiation.

Scientists have for the first time witnessed the mechanism behind explosive energy releases in the Sun's atmosphere, confirming new theories about how solar flares are created.

In 2012, a rapid succession of coronal mass ejections - the most intense eruptions on the sun - sent a pulse of magnetized plasma barreling into space and through Earth's orbit.

In the giant system that connects Earth to the sun, one key event happens over and over: solar material streams toward Earth and the giant magnetic bubble around Earth, the magnetosphere helps keep it at bay.

On Feb. 24, 2014, the sun emitted a significant solar flare, peaking at 7:49 p.m. EST. NASA's Solar Dynamics Observatory (SDO), which keeps a constant watch on the sun, captured images of the event.

Space Weather Explosions at Venus

Researchers recently discovered that a common space weather phenomenon on the outskirts of Earth's magnetic bubble, the magnetosphere, has much larger repercussions for Venus.

NOAA Ovation Aurora Model Goes Operational

The aurora is highly correlated with a number of space weather impacts on systems making forecasting the location and intensity of the aurora important.

Sun Spits Out Mid-Level Solar Flare

The sun emitted a mid-level solar flare, beginning at 11:57 p.m. EST on Feb. 3, 2014, and peaking at midnight EST.

Unprecedented Images of the Sun

The region located between the surface of the sun and its atmosphere has been revealed as a more violent place than previously understood, according to images and data from NASA's newest solar observatory, the Interface Region Imaging Spectrograph, or IRIS.

Stunning Video: Roots of Life

This video was directed by Rajan Mehta, combining his footage of the aurora borealis with imagery from NASA's Solar Dynamics Observatory.

The sun emitted a significant solar flare, peaking at 5:12 p.m. EST on Nov. 5, 2013. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel.

Sun Continues to Emit Flares

After emitting its first significant solar flares since June 2013 earlier in the week, the sun continued to produce mid-level and significant solar flares on Oct. 27 and Oct. 28, 2013. Solar flares are powerful bursts of radiation.

A magnetic filament of solar material erupted on the sun in late September, breaking the quiet conditions in a spectacular fashion. The 200,000 mile long filament ripped through the sun's atmosphere, the corona, leaving behind what looks like a canyon of fire.

Here is a video fo today's beautiful arching prominence eruption on the north western limb of the Sun. One the prominence breaks, some of the plasma flows back to the solar surface, moving along the magnetic field lines. This view is in 304 angstroms wavelength of the extreme UV light.

The Sun Sends Two CMEs Toward Mercury

On the night of April 24 and the morning of April 25, 2013, the sun erupted with two coronal mass ejections (CMEs), solar phenomena that can send billions of tons of solar particles into space that can affect electronic systems in satellites.

Sol is the world's first interplanetary weather app. The mobile and tablet application integrates weather data from the Curiosity rover on Mars with weather data from here on Earth. The project aims to provide users with a sleek, visually appealing weather app that also incorporates information about the conditions and temperatures on Mars.

Also, a second companion app was created to augment the Sol experience. The augmented reality application offers two scenes for users to experience on Mars. The first scene allows users to a control a 3D version of the Curiosity rover as it rolls across the planet and through weather events, like a dust storm. In this scene, facts about Mars and weather on the planet appear as the rover moves around. The second scene is a 3D version of Mars that allows users to spin the planet around and read facts about the planet.

Sun Emits a Mid-Level M6.5 Flare

The M6.5 flare on the morning of April 11, 2013, was also associated with an Earth-directed coronal mass ejection (CME), another solar phenomenon that can send billions of tons of solar particles into space and can reach Earth one to three days later.

Quiet Interlude in Solar Max

Something unexpected is happening on the Sun. 2013 was supposed to be the year of "solar maximum," the peak of the 11-year sunspot cycle. Yet 2013 has arrived and solar activity is relatively low.

New Sunspots Are Producing Space Weather

On Jan. 13, 2013, at 2:24 a.m. EST, the sun erupted with an Earth-directed coronal mass ejection or CME. Not to be confused with a solar flare, a CME is a solar phenomenon that can send solar particles into space and reach Earth one to three days later.

Sun Emits a Mid-level Flare

On Nov. 13, 2012, the sun emitted a mid-level solar flare, peaking at 9:04 p.m. EST.
