This is the best tl;dr I could make, original reduced by 97%. (I'm a bot)
> Major changes are coming in 2022 across the atmosphere and the oceans, creating different weather patterns into the second half of the year, and especially in the cold season later in the year.
> Lower pressure over Greenland helps to keep the jet stream more to the north, allowing a high-pressure area to expand over much of Europe.
> You can notice the warmer temperatures over much of Europe, which would suggest a pattern change to a more westerly flow in early 2022.
> Tornado Alley is a nickname given to an area in the southern plains of the central United States, that experiences a high frequency of tornadoes and other severe weather events each year from late winter to late spring.
> The outcoming jet stream can then merge with the systems in the North Atlantic, helping to create a whole new weather pattern for Europe.
> Looking at the snow anomalies below, we can see the above-average snowfall over much of the eastern United States and also Europe.

Hi DTG reddit, this is my first post here! I had this thought a little bit ago and was like "oh my god but what IF--"
So, context...you can google "europa subsurface ocean" to get a lot of neat popular science articles and also some journal articles about this, but long story short, there's a lot of indirect/circumstantial evidence that Europa has a saltwater ocean down beneath its ice surface. Estimates are something like 80-170 km of water topped by several km of ice. While I doubt the DSC would be at the very BOTTOM of that - though it would be amazing if it was, who knows what we became capable of in the Golden age? - I mean, it being down there in general would explain why hasn't been found.
I unfortunately have pretty much no evidence for this beyond the fact that it's called the /Deep/ Stone Crypt. In fact it seems more likely that the DSC is deep in the ice itself to judge by the Beyond Light gameplay trailer. But as an astrophysicist - though this is more planetary science and astrooceanography, which are very not my specialties - I think it would be SUCH a cool setting for Destiny. So maybe this is really just me pleading for us to be given another, proper, ocean setting since we can't really. Do anything with the methane oceans on Titan other than die in them. Which is disappointing.
ETA: THE EXPANSION IS CALLED BEYOND LIGHT WHAT'S MORE BEYOND LIGHT THAN A SUBSURFACE OCEAN THAT'S BASICALLY ONE BIG ABYSSOPELAGIC ZONE. also sea monsters.
...I don't know how much discussion this will generate or if it might get tagged as low-effort/low-quality so if you also want to ask questions about space and astronomy-related things in Destiny I'm game to have that discussion too.
What would the implications be of multiple moons having some form of life outside of Earth?
Long title, but I had to capture your attention :-)
I am working on a hard sci-fi short story about a probe we launched to dig through the icy crust of Enceladus to get to the ocean below. We know from data collected by the Cassini probe that ocean have organic compounds, because we found several when Cassini passed through a geyser plume in 2017 if I'm correct. This story is much more about describing how would be a culture of such an isolated civilization would be, and I have absolutely no idea on how to end it.
Evolving in a subsurface ocean, without a sky to look at night and wonder about the stars and without a light cycle of day and night, this civilization has no concept whatsoever neither of time or about other stars and planets. Being completely in dark, creatures there do not have eyes, and rely on their hearing and echolocation for everything.
So far, no matter how I think on this story, I can only describe how amazing and unique their biology, culture and science are, but I can't think of a proper plot to it. The best I can think is structuring this story akin to Clarke's Rendezvous With Rama, which is essentially a descriptive work with a somewhat shoehorned drama in the end, before the Rama ship simply zips away.

In this thread, design your own creature or ecosystem to answer the prompt. You may illustrate or write a post for your response.
The Prompt Of The Week is Creatures of Subsurface Oceans.
-
What if alien life were discovered on Europa, Ganymede, or Enceladus? How would life develop with its source of energy being tidal heating in a subsurface ocean?
-
Post your interpretation of what creatures might evolve in the eternally dark oceans of such worlds.
-
Single celled or complex, bioluminescent or eyeless, radial or bilaterian, divergent or convergent with Earth, it is up to you.
-
A fictional planet similar to these Jovian and Saturnian moons is also allowed.
I already tried this a few days ago, but my starting point was a bit unclear, so let's give us a definitive base to work with. The story so far: Humans have colonised the subsurface oceans of the moon Europa in drifting underwater habitats, growing their algae and animal life (taken from earth, with some minor genetic modifications, which we will get to later) in insulated aquacultures under artificial UV light. Eventually, some of of these critters escape from their safe confines and live in the open waters around the habitats. Eventually, due to their scientific curiosity, humans build stationary, fission-powered artificial reefs with light and the necessary flora as wildlife sanctuaries.
We start with these organisms:
Arctic char, atlantic cod, halibut, european lobster, blue mussel, european abalone and some squids (due to contamination, some jellyfish and sessile organisms of your choice also made the cut).
... as well as the necessary microflora and -fauna to keep them alive. The biomes they will be exposed to are: the open kelp farms of the habitats, the illuminated open water immediately near the habitats, the increasingly dark open waters further away, the surface of the habitats themselves and eventually the artificial reefs, including rock clefts, as well as the underside of the surface ice sheet.
And lastly, the general characteristics of Europa and the initial genetic modifications of our starting organisms: We are talking about cold, nutrient-poor waters (oxygenation and salt concentration could however be entirely normal) and due to the reduced gravity, you need to go 75 m deeper to experience a pressure increase of 1 bar, instead of the 10 m on earth. Due to the 15 km ice sheet above, there is no source of natural light and at the top of the subsurface ocean, pressure is comparable to a depth of ca. 1900 m on earth. Therefore, imported fish have been modified to have no swim bladder, more desaturated fatty acids in their cell membranes and higher levels of TMAO in their bloodtream, to make them more restistant to the pressure.
That would be all from me. I am looking forward to see what you make of this. What would be likely adaptations to occur from this point on and what kind of ecosystem would emerge starting from these animals?
