The Sun Produces Two CMEs

In the evening of Feb. 5, 2013, the sun erupted with two coronal mass ejections or CMEs that may glance near-Earth space.

Solving The Solar Corona Puzzle

The Sun's visible surface, or photosphere, is 10,000 degrees Fahrenheit. As you move outward from it, you pass through a tenuous layer of hot, ionized gas or plasma called the corona. The corona is familiar to anyone who has seen a total solar eclipse, since it glimmers ghostly white around the hidden Sun.

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.

Proba-2 Soaks Up Three Solar Eclipses

ESA's Sun-watching Proba-2 satellite experienced three partial solar eclipses last night while lucky observers watching from northern Australia were treated to a total solar eclipse.

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.

The sun emitted a significant solar flare on Oct. 22, 2012, peaking at 11:17 p.m. EDT. The flare came from an active region on the left side of the sun that has been numbered AR 1598, which has already been the source of a number of weaker flares. This flare was classified as an X.1-class flare.

The Sun is nearly the roundest object ever measured. If scaled to the size of a beach ball, it would be so round that the difference between the widest and narrow diameters would be much less than the width of a human hair.

One of the Fastest CMEs On Record

On July 23, 2012, a massive cloud of solar material erupted off the sun's right side, zooming out into space, passing one of NASA's Solar TErrestrial RElations Observatory (STEREO) spacecraft along the way.

One Half Million Mile Solar Filament

This image from NASA's Solar Dynamics Observatory (SDO) shows a very long, whip-like solar filament extending over half a million miles in a long arc above the sun's surface.

According to NASA it's pure science and not art. But when Nicholeen Viall, a solar scientist at NASA's Goddard Space Flight Center created a new data visualization technique, the resulting solar images were reminiscent of a Van Gogh painting.

Independence Day Solar Fireworks

This image, captured by the Solar Dynamics Observatory, shows the M5.3 class solar flare that peaked on July 4, 2012, at 5:55 AM EDT.

The first images of an upward surge of the Sun's gases into quiescent coronal loops have been identified by an international team of scientists. The discovery is one more step towards understanding the origins of extreme space storms, which can destroy satellite communications and damage power grids on Earth.

NASA's Solar Dynamics Observatory (SDO) captured approximately 18 hours of video for this dancing plasma from June 24 through June 25. Suspended in twisted magnetic fields, the hot plasma structure is many times the size of planet Earth.

The Solar Dynamics Observatory captured this image of an M1.2 class flare on June 13, 2012.

SpaceRef had the opportunity to sit down with Dr. Leroy Chiao at the 28th National Space Symposium in Colorado Springs. Dr. Chiao is a veteran of four flights into space and was the Expedition 10 commander and NASA science officer on his last mission to the International Space Station.

A New Way For People To See The Sun

NASA Awards Grant to Chabot Space & Science Center For Space Weather Exhibition

"The centerpiece of the exhibition will be compelling high resolution imagery of the Sun from NASA's SDO mission, provided to Chabot by Lockheed Martin Solar and Astrophysics Laboratory. The mesmerizing visualizations of eruptions, flares, prominences, and coronal mass ejections are all the result of colossal magnetic disturbances taking place right next to our planet. Interactive stations in the exhibition will illustrate the outcome of solar storms, displaying colorful aurora, and forecasting geomagnetic storm warnings."
