Sun and heliosphere images by STEREO
STEREO uses two nearly identical spacecraft for stereoscopic imaging of the Sun.
STEREO - Solar TErrestrial RElations Observatory
STEREO - the Solar TErrestrial RElations Observatory is a solar observation mission using two almost identical spacecraft laboratories - one before and one after the Earth, in its orbit oround the Sun. STEREO's primary function is to make the first stereoscopic images and measurements, in the study of our Sun and the nature of its coronal mass eruptions (CME).
Below are the latest images received from the beacons of SECCHI space observatories. 24 hours a day telemetry, sent by the two spacecrafts of STEREO is a highly stream of data with low resolution, used for prediction of the space weather and magnetic storms. Because of the high compression of the observed data, these images are much lower quality.

The images above are shown in the order of the relative positions of the both viewpoints, Behind and Ahead. For the Heliospheric Imager (HI) images below, the order is reversed to reflect the fact, that the HI Ahead telescopes look to the left of the Sun, and those on Behind look to the right. Also, the HI images are not rotated to put solar north up.

Orbital location of STEREO now and the orbits of observatories
Current location of the both spacecrafts of STEREO space observatory. They are following the Earth's orbit around the Sun. Point A (the red point) is STEREO Ahead (the spacecraft before the Earth) and point B (the blue point) is STEREO Behind (the spacecraft after the Earth).
