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

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

Understanding the sun from afar isn't easy. How do you figure out what powers solar flares - the intense bursts of radiation coming from the release of magnetic energy associated with sunspots - when you must rely on observing only the light and particles that make their way to near-Earth's orbit?

This combination of three wavelengths of light from NASA's Solar Dynamics Observatory shows one of the multiple jets that led to a series of slow coronal puffs on Jan. 17, 2013.

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.

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.

The sun emitted a significant solar flare, peaking at 1:48 p.m. EDT March 29, 2014, and NASA's Solar Dynamics Observatory captured images of the event. Solar flares are powerful bursts of radiation.

The Solar Cycle As Seen by SOHO

It took 10 years to create this image of our changing Sun. Taken from space by the Solar and Heliospheric Observatory (SOHO), it shows a dramatically different picture than the one we receive on Earth.

NASA's Solar Dynamics Observatory captures images of the sun in many wavelengths of light at the same time, each of which is typically colorized in a different color.

IRIS Views Its Strongest Solar Flare

On Jan. 28, 2014, NASA's Interface Region Imaging Spectrograph, or IRIS, witnessed its strongest solar flare since it launched in the summer of 2013.

An active region of the sun just rotating into the view of NASA's Solar Dynamics Observatory gives a profile view of coronal loops over about a two-day period, from Feb. 8-10, 2014.

An active region of the sun just rotating into the view of NASA's Solar Dynamics Observatory gives a profile view of coronal loops over about a two-day period, from Feb. 8-10, 2014.

A pigment once daubed onto prehistoric cave paintings is set to protect ESA's Solar Orbiter mission from the Sun's close-up glare.

Sun Spits Out Mid-Level Solar Flare

The sun emitted a mid-level solar flare, beginning at 11:57 p.m. EST on Feb. 3, 2014, and peaking at midnight EST.

A Lunar Transit of the Sun

On Jan 30, 2014, beginning at 8:31 a.m EST, the moon moved between SDOor SDO, and the sun, giving a view of a partial solar eclipse from space.

This image, taken on Dec. 31, 2013 by the AIA instrument on NASA's Solar Dynamics Observatory at 171 Angstrom, shows the current conditions of the quiet corona and upper transition region of the Sun.

Telescopes help distant objects appear bigger, but this is only one of their advantages.
