Quiz: Cellular or Celestial — can you tell the difference? Continuing with Day 3 of the week-long challenge.
They get more beautiful, but harder to crack.

Quiz: Cellular or Celestial — can you tell the difference? Continuing with Day 3 of the week-long challenge.

madame scientist's not-so-mad musings 
left is a nebula I think and the right a cell.
William Tatum I had it the opposite.
I’d agree they are getting tougher to figure out, depending on how they are cropped. However both of these images are gorgeous.
Answers revealed at midnight, Kimberly Brosnan . They do give details of what they are and links to the original images. I’ll post them on this thread tomorrow am.
I’m going with the left being celestial and the right being cellualr.
I went with left celestial and the right cellular. Thanks for sharing this, it’s fun playing with science.
Left is cellular, right is celestial.
Celestial left?
Left is cellular, and right is celestial (a white dwarf?)
Remember, just because it looks starry/grainy doesn’t mean that it’s celestial.. Most micrographs &c look the.same.. Though the first one DOES look cellular(could be a gas cloud also)
ANSWERS : we were all wrong, at least partly! Both images are cellular! Left is a cell labeled with red for lysosomes (garbage bins of cell) and green for a receptor protein. See: http://www.cellimagelibrary.org/images/13700
Right is also a cell: labeled with three colors (hence the white) for laminins and integrins. See http://www.cellimagelibrary.org/images/12288
There is a galaxy that looks like an eye ( http://t1.gstatic.com/images?q=tbn:ANd9GcSe9tjPSJjIUwVJ2RYMr5yAjpg80YXfYDoPOpcAloTgo_VnLE2T2w). Image on the right looks similar to it. Suppose if the img on the left has nebula(galactic cloud) and stars then it is strange that there are sections of nebula as intense as the green dots (stars according to this assumption). I would expect intensity of radiation from nebula to be less than stars.
Oops.. didn’t read the answer above 🙂
I’ll put up another pair of images, Jatin Lodhia – without the answers 🙂
I have always enjoyed your postings, please keep up the good work…!!!
Thank you, William Phillips 🙂
