Did you know that one of the most notorious poisons is also a key ingredient for life as we know it? Join space chemist Karin Öberg and learn how she scans the universe in search of this paradoxical chemical using ALMA, the world’s largest radio telescope, to detect hotbeds of molecular activity and the formation of life-sustaining planets.

In a discussion of this topic, one must first decide how the universe began.
If one approaches the subject in terms of a Creator, then the entire premise changes

But aren’t we presuming that life can only exist in the form we see it as. That life can only exist in an earth like planet?

We are not presuming it *only* exists in that form, but we have to start somewhere, otherwise the possibilities would be endless and we’d have no idea where to start looking!

Thank you Karin Öberg. That’s the first time I’ve seen such a positive assessment. One billion planets spread randomly about our galaxy. I make that about one every 10-20 light years or so on average.

It’s just an assumption that planets form by accretion in discs. There is much more evidence that planets are formed inside stars and are ejected during recurring Nova events.

Much more evidence?
Bearly Listening
May 5, 2020 at 11:21 pm
a Yes. No one has ever witnessed a planet formed by accretion of molten rocks slamming into each other. The SAFIRE project has created a star in a laboratory though and one of the byproducts is the consolidation of spherical metallic bodies in the outer shell of the plasma reactor. We’ve also witnessed novas where dust clouds are ejected and the star remains, which disproves the idea that stars only explode at the end of their lives. Why do you think planets are always orbiting stars and not just floating around randomly in space?

Well, yes but the most important ingredient is missing here. CO2. In other words: If there is a planet with only water, nothing will happen unless there is abundance of C.

Ingredient 4. Magnetic field. Detecting that may be harder than detecting atmospheric molecule composition, though it could be inferred. Without a magnetic field, much of an atmosphere would be stripped away. Other lesser ingredients may be… have days (not tidally locked), or gravity strength, etc.

This seems a filler tedtalk. Because there was no conclusion. All we know is that there is a recipe for an habitable planet and that there is a lot of out there. This didn’t have to be so long. This could have been done in 3 minutes to state the simple recipe.

Wow, I never thought of real possibility to have a lot of living planets out there. In my mind, life was a rare and pretty much random thing to happen, but this woman gave me a lot to think about.
Thank you for this talk.

How many of these living planets have their inhabitants evolve beyond that of a colony of unspecialised cells?
A slimeball planet is just as interesting to me as a dead planet. Microbes are everywhere on the surface of Earth but they are very boring.
Anastasiya Bernackaya
May 8, 2020 at 9:32 pm
@Don Hyon Life evolved from the bacteries themselves, so at least having them is a gift, not a given, even if you think they are boring. The whole point is to find any life, that would mean we are not the only organics here.

What about having enough gas giants in the planet’s solar system to protect the planet against regular asteroid impacts, allowing time for life to develop? What about the planet’s solar system’s position in the galaxy, as outer solar systems are less turbulent (fewer asteroids, fewer supernova gamma-rays, etc)? What about the condition of the planet’s magnetosphere/if the planet has an active dynamo, won’t solar radiation destroy life without it? I think the recipe for life might require more ingredients than just being in the Goldilocks Zone, earth-like geography, and the right chemicals. No expert, just wondering if she could have included these as possible requirements for life in her presentation.

Why does the speaker assume that finding life on other planets is “good news”? I can imagine a scenario when we locate and contact them, and then they come and kill us all. Read Douglas Adams to fully get this idea. It seems far more likely than the ‘friendly hypothesis’ to me, looking at current and past species here on planet Earth!
Dustin Nelson
May 10, 2020 at 8:08 pm
“life” doesn’t necessarily mean “intelligent life.” And it definitely doesn’t mean intelligent life capable of traveling hundreds or thousands of lightyears to come annihilate us. That’s literal science fiction. No one is hypothesizing that’s the case. She’s talking about microscopic life and plant and animal life. There is no reason to assume intelligent life capable of advanced space travel is at all common or even exists at all.

Bison Bolzelow

I wonder why she always says, such a planet must have liquid water on it for supporting life. Why aren’t they at least considering the possibility of life emerging from other systems?
For example a planet, that is a bit colder and has big amounts of liquid ammonia on it? It has similar traits compared to water and with the right other molecules, i guess the organic chemistry on such a planet could also be pretty interesting.
Does anyone know if there’s a reason why this doesn’t need to be considered?
