Best Evidence Yet For Coronal Heating Theory Detected by NASA Sounding Rocket

08.01.2014
Scientists have recently gathered some of the strongest evidence to date to explain what makes the sun's outer atmosphere so much hotter than its surface.

NASA's SDO Observes a Lunar Transit

07.28.2014
On July 26, 2014, from 10:57 a.m. to 11:42 a.m. EDT, the moon crossed between NASA’s Solar Dynamics Observatory and the sun, a phenomenon called a lunar transit.

Peering through the Layers

07.28.2014
This collage of images shows an active region on the Sun taken at almost the same time in four wavelengths of extreme ultraviolet light (July 24, 2014 at about 17:56 UT).

Spun and Confused

07.23.2014
A long arch of plasma (called a prominence) was pulled this way and that by magnetic forces for a week before it finally dissipated (July 10-16, 2014).

Spots Galore

07.18.2014
The Sun sported a whole slew of sunspots over the last 11 days (July 1-10, 2014). Sunspots are darker, cooler regions on the Sun created by intense magnetic fields poking through the surface.

Sun's Plasma Burst

07.10.2014
A stream of plasma burst out from the sun, but since it lacked enough force to break away, most of it fell back into the sun (May 27, 2014).

NASA MESSENGER and STEREO Measurements Open New Window Into High- Energy Processes on the Sun

07.09.2014
MESSENGER is near enough to the sun to detect solar neutrons that are created in solar flares. How far they travel into space depends on their speed with an average lifetime of 15 minutes.

NASA's SDO Spots a Summer Solar Flare

07.09.2014
On July 8, 2014, an eruption of solar material was seen arcing up and away. After it left the sun, this became a coronal mass ejection, a giant cloud of solar material, headed toward Mars.

NASA's STEREO Entering New Stage of Operations

07.03.2014
The STEREO spacecraft's are about to enter a new phase of their journey: a time when the bright light and heat of the sun (Superior Conjunction) will stand in the way of sending data back to Earth.

Q & A for Operations of STEREO During Superior Conjunction

07.03.2014
Questions and Answers for Operations of STEREO mission during its upcoming Superior Conjunction period.

Puffing Sun Gives Birth To Reluctant Eruption

06.27.2014
On Jan 17, ESA and NASA (SOHO) spacecraft observed puffs emanating from the base of the corona and rapidly exploding outwards into interplanetary space. The puffs occurred roughly once every 3 hours.

NASA's STEREO Maps Much Larger Solar Atmosphere Than Previously Observed

06.25.2014
Using NASA's STEREO, scientists have found that the sun's atmosphere, called the corona, is even larger than thought, extending out some 5 million miles above the solar surface.

Sun Emits 3 X-class Flares in 2 Days

06.11.2014
Three X-class flares erupted from the left side of the sun on June 10-11, 2014. These images are from NASA's SDO and show light in a blend of two ultraviolet wavelengths: 171 and 131 angstroms.

NASA's SDO Sees 2 Solar Flares

06.10.2014
The sun released a second X-class flare, peaking at 8:52 a.m. EDT on June 10, 2014. This is classified as an X1.5 flare.

Coronal Hole Squared

05.13.2014
A coronal hole, almost square in its shape, is one of the most noticeable features on the Sun of late (May 5-7, 2014). A coronal hole is an area where high-speed solar wind streams into space.

Mid-level Solar Flare Erupts from the Sun

05.08.2014
The bright light on the left side of the sun shows an M5.2-class solar flare in progress on May 8, 2014.

Mid-level Solar Flare Erupts from the Sun

05.08.2014
The sun emitted a mid-level solar flare, peaking at 6:07 a.m. EDT on May 8, 2014, and NASA's Solar Dynamics Observatory, or SDO, captured images of it. Solar flares are powerful bursts of radiation.

NASA Telescopes Coordinate Best-Ever Flare Observations

05.07.2014
On March 29, 2014, an X-class flare erupted from the right side of the sun... and vaulted into history as the best-observed flare of all time.

Carrington-class CME Narrowly Misses Earth

05.05.2014
n July 23, 2012, a plasma cloud or "CME" rocketed away from the sun as fast as 3000 km/s, more than four times faster than a typical eruption.

Dark Lift-Off

05.05.2014
A small, hovering mass of twisted strands of plasma shifted back and forth before erupting into space (Apr. 29-30, 2014) over a period of just one day.

Spasmodic Active Region

04.29.2014
An active region that was rotating out of view off the sun's western limb, displayed a dazzling variety of dozens of spurts and eruptions in about 2.5 days (Apr. 19-21, 2014).

X-class Flare Erupts from Sun on April 24

04.25.2014
The sun emitted a significant solar flare, peaking at 8:27 p.m. EDT on April 24, 2014. Images of the flare were captured by NASA's Solar Dynamics Observatory.

Sun Emits a Mid-level Solar Flare

04.18.2014
A mid-level flare burst from the sun on April 18, 2014, as seen as a bright spot in the center of this image. The image was captured by NASA's Solar Dynamics Observatory in 304 angstrom.

Bright Points in Sun's Atmosphere Mark Patterns Deep In Its Interior

04.17.2014
New research that uses data from SDO, to track bright points in the solar atmosphere and magnetic signatures on the sun's surface offers a way to probe the star's depths faster than ever before.

Solar Gusher

04.15.2014
An active region blew out a flare (bright flash) and a dark rush of plasma spewing above the Sun (Apr. 4, 2014). Then the semi-transparent plasma seemed to turn and shift in planes.
