NASA Ultra-Black Nano-Coating to Be Applied to 3-D New Solar Coronagraph

10.22.2014
An emerging super-black nanotechnology will be applied to a complex, 3-D component critical for suppressing stray light in a new, smaller, less-expensive solar coronagraph.

NASA's SDO Observes an X-class Solar Flare

10.20.2014
A solar flare surges off the lower left hand of the sun in this image captured by NASA's SDO on Oct. 19, 2014.

Coronal Loops, Anyone?

10.20.2014
SDO captured a splendid example of expanding coronal loops seen in profile at the edge of the Sun (Oct. 14-15, 2014).

IRIS Helps Explain Mysterious Heating of the Solar Atmosphere

10.16.2014
The Interface Region Imaging Spectrograph was launched with a specific goal: track how energy and heat courses through a little understood region of the sun called the interface region.

NASA SDO Image: Jack-o-Lantern Sun

10.14.2014
Active regions on the sun combined to look something like a jack-o-lantern’s face on Oct. 8, 2014.

SDO Watches Giant Filament on the Sun

10.03.2014
A snaking, extended filament of solar material currently lies on the front of the sun-- some 1 million miles across from end to end.

NASA Releases Images of a Mid-level Solar Flare

10.02.2014
The sun emitted a mid-level solar flare, peaking at 3:01 p.m. EDT on Oct. 2, 2014. NASA's Solar Dynamics Observatory, which watches the sun 24-hours a day, captured images of the flare.

NASA's Releases Images of a Mid-level Solar Flare

09.29.2014
The sun emitted a mid-level solar flare, peaking at 10:58 p.m. EDT on Sept. 27, 2014, and NASA's Solar Dynamics Observatory captured images of the event.

SDO POTW: Lots of Spots

09.29.2014
Over the past month (Aug. 25 - Sept. 25, 2014) the Sun has produced quite a few sunspot groups, with some of them being significantly large.

A Twisting Blob of Plasma

09.26.2014
A twisted blob of solar material – a hot, charged gas called plasma – can be seen erupting off the side of the sun on Sept. 26, 2014.

CME Week: How NASA Watches CMEs

09.25.2014
These images were produced from a space weather model known as ENLIL named after the Sumerian storm god. It shows the way a coronal mass ejection (CME) on March 5, 2013, was expected to travel.

NASA's SDO Sees an Autumnal Lunar Transit

09.25.2014
On Sept 24, 2014, from 2:50 a.m. to 3:20 a.m. EDT, the moon crossed between NASA’s Solar Dynamics Observatory and the sun, a phenomenon called a lunar transit.

CME Week: Mapping the Journey of a Giant Coronal Mass Ejection

09.24.2014
Scientists clocked a July 2012 CME as traveling between 1,800 and 2,200 miles per second as it left the sun. NASA STEREO's helped scientists create models of the entire July 2012 event.

CME Week: The Difference Between Flares and CMEs

09.22.2014
There are many kinds of eruptions on the sun. Solar flares and coronal mass ejections both involve gigantic explosions of energy, but are otherwise quite different.

Media Invited to See NASA’s MMS Spacecraft Prior to Shipment for Launch

09.22.2014
MMS will provide the first ever three-dimensional view of the reconnection process, which is one of the most important drivers of space weather events.

Extensive Arch

09.19.2014
A giant arch of plasma rose up out of the Sun and then stretched itself until it had reached back to a point behind our view of the Sun (Sept, 17-18, 2014).

NASA Releases IRIS Footage of X-class Flare

09.17.2014
On Sept. 10, 2014, NASA's newest solar observatory, the Interface Region Imaging Spectrograph, or IRIS, mission joined other telescopes to witness an X-class flare.

Earth-directed X-class Flare

09.17.2014
An active region just about squarely facing Earth erupted with an X 1.6 flare (largest class) as well as a coronal mass ejection on Sept. 10, 2014.

A Significant Flare Surges Off the Sun

09.10.2014
