Observing the image of the Parker Solar Probe https://www.nasa.gov/feature/goddard/2021/unique-solar-system-views-from-nasa-sun-studying-missions where we can see the phenomena on brightness in Venus, Earth and Mars planets which are planets with atmosphere and water, can we consider the phenomena of the brightness in planets as a biosignature for the planetary habitability?
In S4:E25 of TNG, “In Theory”, Worf enters Picard’s ready room and scans his desk. He says something along the lines of “there are clearly multiple life forms detected, but the only biosignature is your own. You didn’t...?”
Picard replies immediately, “no I did not”.
So... Worf is accusing Picard of choking the chicken meters away from the main bridge? And he’s guessing the multiple biosignatures are some grade A Picard swimmers? I’ve wracked my brain and cannot come up with another interpretation.
Small amount of phosphine has been discovered in the atmosphere of Venus. This may be of biological origin (there may be abiologial processes as well). This may mean that missions to Venus get a priority in the next decade (thoughts?). The signature is at or above 50km (which is quite OK for later human habitation as well since pressure, temperature and gravity are Earth-like, although the "air" is toxic). So can we use Starship to ship the necessary equipment (probably some kind of airship-based solution)?
Edit: spelling
Hi everyone,
I have a little "noob" question - can anyone elaborate when and how Perseverance will search for biosignatures?
P.s. From what I understood that is done by SuperCam tool, but it is not really clear "in simple words" + I dont really understand how the overall process looks like.
Thanks!
Hi all, happy holidays! I am a PhD candidate at the Center for Interdisciplinary Exploration and Research in Astrophysics and Northwestern University.
I am so excited to share with the community my recent research published in Nature Astronomy! The direct link to the article is here: https://www.nature.com/articles/s41550-020-01264-1, and you can access a free view-only version of the paper here: https://rdcu.be/ccycX
In the latest chapter of my PhD thesis, I teamed up with MIT, CU-Boulder, NASA Astrobiology Institute, and University of Chicago to study the 3D effects of stellar flares on exoplanetary atmospheres. Our study predicts atmospheric chemistry of worlds exposed to frequent flares may be different from our world, but perhaps habitable. Interestingly, in some cases, stellar flares can actually help us detect signs of life!!
Want to know more? Check out the NU press release here and IFLscience story here. Also, take a look at these illustrated videos on Youtube summarizing our paper. One with voice over (https://youtu.be/QxQjp-awlQg), and another with music and captions (ttps://youtu.be/oEZM6ZABPHA)
Have questions? Free feel to ask them here and I will try to get to them as soon as I am able.
Thanks in advance for your interest in my research!!
Sousa-Silva, an MIT astrochemist who co-authored the recent study finding phosphine on Venus, and McTier, an astrophysicist, folklorist, and science communicator, will talk about the search for life and habitable worlds through exotic biosignatures in our galaxy and beyond. What questions do you have for them?
We'll be using your questions in the live interview and link to the conversation tomorrow at 2 p.m. ET for those that want to see Sousa-Silva and McTier's responses in real time.

By biosignature I mean the specific atmospheric gases, surface reflectance features, photosynthetic pigments etc.
Of course ignoring the cases where they chose not to contact us, and they have tried contacted in the past and we aren't technologically advanced yet to understand it.
