Yeah, I can't wait to find out what's going on-- and why they've never been noticed till now.

There's cotton growing on the Moon!

I wonder how much the tee shirt they make from it will cost. :D

Actually, it sounds like the plant experiments are not doing too well so far. I wonder which of the culprits listed in the article are responsible. I think we can discount the launch and the low gravity. I'm a bit dubious about the radiation, too, although I wouldn't be surprised to see mutations if the cotton continues to grow and the other plants sprout. I think the temperature swings are probably the most likely reason, although the article doesn't specify how extreme those swings are-- and you'd think they would have done as much as possible to protect the plants from all these hazards.

Yeah, they didn't make it. :no:
Though reading the article the experiment did seem a little half-hearted as no heater was included. Plant seeds sent to Lunar orbit have done well before as many of the Moon Trees are still alive.

Aww, the poor plants. :( What did they expect to happen with no heater? They essentially sent them to their doom.

An interesting follow-up on the oddities of Oumuamua:

This looks quite interesting. I'll see if I can watch it over a jug of tea in the morning.

Not a JUG of Twisted Tea, I hope.

Oh well, allowing for seasonal adaptation (definitely missing this year), this may be the first good snowstorm we've had since 2017. Go for it.

(However, looking at the snapshot that YouTube chose, I can't help but recall that "Thought" was my nickname from '83-'86.)

That certainly contained a lot of food for thought as to how the data can be interpreted in multiple ways, which alter the size and shape of Yomama-- even turning it into a light sail. And it's kind of weird that it can be at rest relative to the local group, but still manage escape velocity from the Solar System. I'm not sure if I quite understand that part. Unfortunately the scientist spent a lot of time making irrelevant arguments, like Einstein's reluctance to accept quantum theory, which gave him kind of a von Daniken vibe.

Yeah, and I have tomorrow off. Why not? :lol:

Some new evidence that complex life on Earth could be much older than previous thought.

Well, that's fascinating and could definitely be interpreted as good news for the possibility of multicellular life on other worlds, if those little guys were indeed linked to that brief oxidization event that he talks about. On the other hand, it may indicate that life may not diversify and evolve as quickly when it achieves multicellularity as we thought it did, giving complex life another hurdle to overcome.

I would go with the oxidation event though as an explanation. Earth's environment was likely pretty hostile yet. I have often wondered though if there had been previous dynasties of life on Earth.

It's too bad we can't know the microscopic details of their anatomy-- I'd be surprised if they didn't have DNA, but what about chromosomes and internal cell structure. They could have been quite alien.

I imagine that they'd have DNA but it's possible that they didn't have a cell structure considering their age.

That's true, at least not very complex structure. But it makes you wonder what the possible variations are.

Considering how many of the (up to now) very first organisms survived, from sharks to lobe-finned fish and from slime fungi to archaebacteria, I wouldn't be surprised if those ancient tube-diggers would still be around in some form or other. Quite frequently, biologists discover "new" species, simply because previousely nobody thought of looking in that particular place.
And fine silt or mud is a habitat that usually gets overlooked, particularly if it's somewhere at the bottom of the sea.

Yeah, the deepest trenches of the ocean could hold survivors of an earlier abiogenesis that survived the mass extinction. I wonder if there are even subterranean environments under the deepest trenches of the ocean floor, or would the pressure make that unlikely?

Devil Worms live pretty far down so it might be possible.

"It scared the life out of me when I first saw them moving." :lol:

I wonder if they've sequenced the DNA of these things. I find it interesting that it resembles "certain unnamed species of the genus." That sounds a little... evasive. And borderline Lovecraftian. :lol:

Looks like Earth was hit by a meteor last December. :tomato:
It's odd though. Even as remote as Bering Sea is, you'd think that somebody would have noticed it. :conf:

Especially with all that megatonnage. Just goes to show, as small as the Earth feels to us these days, it's a pretty big place. :yes:

Looks like SpaceX successfully launched and retrieved its new crew-rated module. They say it will fly with actual astronauts aboard in just a few months. We're getting closer to critical mass.

I want to retire to a space habitat. Or at least a space terrarium.

Well, we may be about to get our first glimpse of a Black Hole. Of course, you can't really see a Black Hole, so it will probably just be the chaos surrounding the Black Hole. Probably. Or else it might be a window into time or a doorway to another dimension. Or we might just see the back of the scientist's head who's looking through the telescope.

There appears to be a new species of human. Since it seems to share some characteristics with Homo floriensis I imagine that they're both descended off the same ancestors.
