The bilateral symmetry is a good indicator of gravitational lensing. The diametrically opposing red features are typical of perfect lensing. If the lens was offset these features would be smeared.

Looking for real life environments for the start of life on earth is futile because modern day bacteria, algae etc. would immediately colonize and modify that environment. Sterile lab investigations are the way to go.

Rather little detail on the detection technique used. I suspect that all is being done is to detect the resulting gamma ray intensity. A much easier thing to do than detect cosmic ray intensity, and not novel. Just take a Geiger counter up with you on your next flight and observe the results. My...

Interesting phenomenom. I have seen this effect to some extent on more visible stars. Variations in infrared sensitivity of CCD detectors can cause variations in image brightness. Older CCD detectors were more sensitive to infrared than modern detectors. Photographic emulsions also show...
