No one has been able to observe Jupiter and its moons for some time as it is too close to the Sun, but that did not stop the STEREO (Behind) COR1 coronagraph from capturing it and its four major ...

Normally we reject images contaminated with pieces of debris flying in front of the lens. However, this debris storm made such a striking image, looking like a flashback to the sixties, that we t...

An erupting prominence glows brightly in this COR1-Ahead image from April 9, 2008. This is by far the brightest prominence seen by COR1 since the start of the mission. Complex twisting motions ar...

An outward bound piece of space debris is captured in these successive COR1 polarization sequences. Occasionally, small pieces of the thermal blanket material surrounding the spacecraft are dislo...
The MkIV data at these heights are noisier than the COR1 data, but one can see that the same CME appears in all images. Some smoothing has been applied to the MkIV data to help bring out the CME.

This composite STEREO EUVI-A/COR1-A image from 2007-April-01 was provided by Dr. Huw Morgan at the University of Wales. He has removed the background from the original images using the normalizin...

This is a 2D histogram of the intensity in COR1-A versus COR1-B (a pixel-by-pixel comparison). If the cross-calibration between the two telescopes was exact, you'd expect the points to lie along ...
