    This popped up as trending on my Facebook, so it must be getting quite a bit of attention!!

    Not a hidden treasure, but is published in 2008 and also seen by reddevil013 in Galaxy Zoo forum in Sept 2007. Also known as the Cheshire Cat (from Alice in Wonderland)

    The two massive lensing galaxies at z=0.43

    There are two lensed galaxies which form 2 white arcs with a radius of 11" and have a redshift of z=0.97 and 0.14

    I wonder why it's just now getting mainstream press attention, then.

    Does it really take 7 years to translate from publication to anyone noticing? 😄

    It is not in the Hubble gallery. Maybe nobody dug it out and made an image? until now? Then good for Judy Schmidt,

    "who submitted a version of the image to the Hubble's Hidden Treasures image processing competition, where anyone can sift through the Hubble's massive data pools to highlight hitherto ignored sights from the stars."

    As they say, these images don't just appear, someone has to do the work of making a pretty picture from the raw image data.
