Some people have noticed an odd shape, sort of a cross inside a circle, entering the field-of-view of the HI2 telescope on STEREO Ahead around February 20,2020. Eventually there is a cone shape that appears next to it. You can see the feature in question in this movie moving from right-to-left, just below the trapezoidal occulter on the right side of the image.
The answer lies on the exact opposite side of the image. At the same time as this strange-looking feature starts being visible, the very bright planet Venus enters the HI2-A field-of-view from the left. Notice that Venus and the feature stay in step almost exactly opposite each other across the middle of the detector. This is not a coincidence. The strange looking geometrical "object" is actually an internal reflection of the planet Venus within the telescope optics. This effect has been seen many times before. Here's a particularly striking example of internal reflections caused by the planet Earth as seen early in the STEREO mission, taken from our image artifacts pages.
Earth is also visible in the movie, but is not as bright as Venus. It is closer to the center of the image.
We have also gotten some questions about why the images from the most recent few days are of lower quality and are sometimes incomplete. This is because our data comes in two streams â highly compressed and lower quality but fast space weather beacon data, which are replaced after a few days with better science-quality images.
That's nothing. I saw polka-dotted elephants once while listening to Hendrix on my quadraphonic stereo...
Well one time I played Black Sabbath at 78-speed, man.
And then what happened?
I saw God.
You saw God.....well that sounds like true enlightenment to me, Bob.
All seriousness aside...
I had to look this up as the blank spot on the image was a little scary...I was thinking Romulan cloaking device.
Any object, natural or man-made, that blocks the light of an object from an observer, typically used in reference to astronomical events.
The moon is the occulter of the sun during a solar eclipse.”
My first thought is that April Fool’s Day is six days from now.
Lol, remember project Blue Book? I’m watching the TV series now.

The MiB are real!
