Partial Solar Eclipse Seen By Proba-2

ESA's Sun-watching Proba-2 satellite experienced three partial solar eclipses on 13 September 2015.

NASA's Solar Dynamics Observatory, which watches the sun constantly, captured these images of a significant solar flare as seen in the bright flash on the left peaking at 6:11 p.m. EDT on May 5, 2015.

The sun's surface is blisteringly hot at 10,340 degrees Fahrenheit -- but its atmosphere is another 300 times hotter.

Groundbreaking images of the Sun captured by scientists at NJIT's Big Bear Solar Observatory (BBSO) give a first-ever detailed view of the interior structure of umbrae -- the dark patches in the center of sunspots -- revealing dynamic magnetic fields responsible for the plumes of plasma that emerge as bright dots interrupting their darkness.

At any given moment, our sun emits a range of light waves far more expansive than what our eyes alone can see: from visible light to extreme ultraviolet to soft and hard X-rays.

SDO Sees The Sun's Two Coronal Holes

NASA's Solar Dynamics Observatory, or SDO, captured this solar image on March 16, 2015, which clearly shows two dark patches, known as coronal holes.

Proba-2 Views The Sun's Corona

This snapshot of our constantly changing Sun catches looping filaments and energetic eruptions on their outward journey from our star's turbulent surface.

SDO Sees Giant Filament on the Sun

A dark line snaked across the lower half of the sun on Feb.10, 2015, as seen in this image from NASA's Solar Dynamics Observatory, or SDO.

Magnetic Field Lines on the Sun

Scientists have developed a way to produce models of where the magnetic field lines are several times each day.

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

Loss of Contact with STEREO Behind

Communications with the STEREO Behind spacecraft were interrupted on October 1, 2014 immediately after a planned reset of the spacecraft performed as part of a test of solar conjunction operations.

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

NASA's Interface Region Imaging Spectrograph (IRIS) has provided scientists with five new findings into how the sun's atmosphere, or corona, is heated far hotter than its surface, what causes the sun's constant outflow of particles called the solar wind, and what mechanisms accelerate particles that power solar flares.

NASA's Solar Dynamics Observatory, or SDO, which watches the sun 24 hours a day, has observed this gigantic filament for several days as it rotated around with the sun.

On Sept. 30, 2014, a sounding rocket will fly up into the sky - past Earth's atmosphere that obscures certain wavelengths of light from the sun -- for a 15-minute journey to study what heats up the sun's atmosphere. This is the fourth flight for the Very high Angular Resolution Ultraviolet Telescope, or VAULT, will launch from the White Sands Missile Range near Las Cruces, New Mexico.

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.

Sun Emits Large X2.2 Flare

The sun emitted a significant solar flare, peaking at 7:42 a.m. EDT on June 10, 2014.

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.
