A bit cheeky, as I submitted my own processing of this image to APOD a couple of weeks ago, but they decided to post someone elses' work. No problemo.
Gonna attach a couple of images from my own processing.

Some forms of like don't require oxygen (or any atmosphere really). Thermal vents, even solid rocks. There are organisms feeding off chemical composition.SpaceCadet wrote: ↑Sun Mar 01, 2020 12:37 pm How is martian life a possibility when there isn't any atmosphere to speak of?

Very cool. I think the "crater" is the result of a collapse. Here's a zoomed in view, with some enhancement of the dark part; seems like there's a pile of sand or soil at the bottom of the hole.

Re: APOD: The Orion Bullets (2019 Mar 03)
One article explains: "At the center of the giant butterfly-like feature is IRc2, a star 30 times more massive than the sun which is in the process of forming. A strong wind with a speed of more than 100 kilometers per second is blowing out from IRc2, evacuating the butterfly-like cavity and al...

Re: APOD: Earthrise 1: Historic Image Remastered (2018 Dec 24)
With the sunlit Moon and Earth in the view, you wouldn't be able to see stars there. Stars are very faint and require dark adaptation. On the topic of the image processing, this is a simple but great idea to use colour from another image for a black&white one. Surprised it hadn't been done befor...

Amazing photo! The author took two photos, and I took the liberty of stitching them together using ICE: http://ibb.co/dvOTu7 https://scontent-lht6-1.xx.fbcdn.net/v/t1.0-9/31047744_10155878130144843_7807785369843584916_n.jpg?_nc_cat=0&_nc_eui2=v1%3AAeFkF5CquSkeQn-gES5uc2BUdJMQUk1IvhRrbp4GykKM0q9a...

Re: APOD: NGC 7635: The Bubble Nebula (2018 Apr 19)
You can tell the expanding bubble encountered strong resistance at around 10-11 o'clock, hence the thick shells and strands of interstellar material. Around 2 to 6 o'clock there was little resistance and that part bubble expanded considerably further. Plus, of course, there's the proper motion of th...

Re: APOD: NGC 7635: The Bubble Nebula (2018 Apr 19)
I don't fully understand the reprocessing... process. Digital colour images are composed of the red, green, and blue channels. Hubble's narrowband images are created by assigning specific ionised gasses (like NII, Ha, and OIII) to the red, green, and blue channels respectively, resulting in a false...
