While no one yet knows what's needed to build a habitable planet, it's clear that the interplay between the sun and Earth is crucial for making our planet livable - a balance between a sun that provides energy and a planet that can protect itself from the harshest solar emissions.

Protecting Earth From Bad Space Weather

This week's spectacular glowing auroras in the night sky further south than usual highlighted the effect that 'space weather' can have on Earth.

SDO Collects Its 100-Millionth Image

On Jan. 19, 2015, at 12:49 p.m. EST, an instrument on NASA's Solar Dynamics Observatory captured its 100 millionth image of the sun.

Severe Space Weather Warning

NOAA has issued a space weather warning of the potential for a geomagnetic K-index of 7 or greater. Severe to extreme space weather conditions may result. Resulting aurora may be seen as low as Pennsylvania to Iowa to Oregon.

Auroras are the most visible manifestation of the sun's effect on Earth, but many aspects of these spectacular displays are still poorly understood.

The sun emitted a mid-level solar flare, peaking at 11:50 p.m. EST on Dec. 16, 2014.

Sun Emits a Mid-Level Flare

One of the two STEREO spacecraft is experiencing communication problems. [Updated]

The sun emitted a significant solar flare on Oct. 19, 2014, peaking at 1:01 a.m. EDT.

Solar Explosions Inside a Computer

The shorter the interval between two explosions in the solar atmosphere, the more likely it is that the second flare will be stronger than the first one.

Significant Flare Surges Off the Sun

The sun emitted a significant solar flare, peaking at 1:48 p.m. EDT on Sept. 10, 2014. NASA's Solar Dynamics Observatory captured images of the event.

New Clues to Determining the Solar Cycle

Approximately every 11 years, the sun undergoes a complete personality change from quiet and calm to violently active. The height of the sun's activity, known as solar maximum, is a time of numerous sunspots, punctuated with profound eruptions that send radiation and solar particles out into the far reaches of space.

NASA's twin Van Allen Probes will celebrate on Saturday two years of studying the sun's influence on our planet and near-Earth space.

On Aug. 24, 2014, the sun emitted a mid-level solar flare, peaking at 8:16 a.m. EDT.

The Sun sported a whole slew of substantial sunspots over the past 11 days (July 1-10, 2014).

Three X-class flares erupted from the left side of the sun June 10-11, 2014. These images are from NASA's Solar Dynamics Observatory and show light in a blend of two ultraviolet wavelengths: 171 and 131 angstroms. The former is colorized in yellow; the latter, in red.

Cutting-edge observations with the 1.6-meter telescope at Big Bear Solar Observatory (BBSO) in California have taken research into the structure and activity of the Sun to new levels of understanding.

A coronal mass ejection, or CME, surged off the side of the sun on May 9, 2014, and NASA's newest solar observatory caught it in extraordinary detail.

M-class Solar Flare Erupts

On April 2, 2014, the sun emitted a mid-level solar flare, peaking at 10:05 a.m. EDT, and NASA's Solar Dynamics Observatory captured imagery of the event.
