Chemical life may be speculated to exist in the atmospheres of brown dwarf stars, given the potential presence of essential elements and conditions. However, comparisons are drawn to the upper atmospheres of Venus and Titan, as well as the middle layers of Jupiter and Saturn, where no signs of life have been found. The lack of solid surfaces for life forms to attach and grow upon raises doubts about the viability of atmospheric life. While birds on Earth are airborne, they originated from land-based life, further complicating the notion of life evolving solely in atmospheric environments. Overall, the current evidence does not support the existence of life in such atmospheres.

It's an interesting bit of speculation in that the right elements and other condition could be present,
but then arguably the situation in the upper atmospheres of Venus and Titan are similar in some respects.
Middle atmosphere layers of Jupiter and Saturn too possibly.
There is no sign of life in the atmospheres of those, so the idea of life evolving in atmosphere so far has zero evidence to support it.
I think the absence of any solid objects which a life form could attach to and grow upon makes the idea unlikely.
We do have birds on Earth, but they are of course descendants of land based life, and are not permanently airborne.

Hi, I saw someone with an avatar on a different forum that turns out to be the sombrero galaxy. AI says, too distant to know much about, aside from billions of starts, potentially tons of planets, and a supermassive black hole in the center. I find that setup fascinating, despite knowing close to nothing about the universe. So I ask: could anyone point me in the direction of, or provide information about this galaxy? I do not trust AI beyond general information, and I like to go pretty...
