Unfortunately we can't replicate one critical feature of the peas using most of the Hubble data - we only have two filters, so we can't look for a weird "bump" in the colours that give the peas their green colour...

Hi, I am still learning about Hubble images, but I think they are cosmic rays.
They hit the CCD camera on Hubble, and make little "exposures"
They are either pure blue cyan (light blue) or pure orange (or whatever the colour is called) , and have sharp edges.
There are more cosmic rays up there above the Earth's atmosphere, and they have to be cleaned out of the images.
Here is a picture taken near the edge of the tile, and you can see the cosmic rays hits near the edge where they haven't been removed.

If I am wrong, someone please correct me.

so pointlike that there is a sort of first airy ring:  wonder if pea or faint star?
