EITHER we aren't alone, or it's nigh time NASA fixed its dodgy cameras.
For the third time this year, the Solar and Heliospheric Observatory (SOHO) has returned an image of a giant UFO hovering near, or feeding off the Sun. Maybe.
SOHO was launched in 1995 as a joint effort between NASA and the European Space Agency, with a sole aim to study the Sun. The mission was supposed to last just two years, but it is still plugging away and has approved support from ESA to continue to do so until at least December.
In recent years, SOHO has found an extended role as a predictor of solar weather activity, helping scientists on Earth prepare for radiation bursts sent our way by solar flares. . . .
