Are There Other Earths? with Lisa Kaltenegger

Alien Earths…Alien Dinosaurs.
Astrophysicist Lisa Kaltenegger, as the founding director of Cornell University's Carl Sagan Institute, leads a team of scientists in a quest to discover life on distant exoplanets using a specialized toolkit informed by Earth's own biosphere and history. In "Alien Earths," she guides us through an eye-opening exploration of unusual exoplanets, such as those with lava oceans, lone wanderers, and multi-sun systems, showcasing the best contenders for alien life. With the help of the James Webb Space Telescope, Kaltenegger demonstrates how we can detect life on other worlds, potentially even those observing us. This new era of exploration raises the question: what if we're not alone in the cosmos?

My favourite nighttime channel. Sip a camomile tea and listen to first half hour then head on pillow and light out for second half hour. Asleep around programs end. Perfect.

[@mogwahcrone3910]

Or pack a bowl 🤘👽❤️

[@pantherstealth1645]

Yep i pack a bowl too but after reading that comment, i think i now need tea.

[@estebandevile2706]

Pillow pilot.

[@SabongiRobert]

Takes me about 2 weeks of sleeps to get through it all. 😂

[@10aDowningStreet]

I tend to wake a lot, always nice to find another episode on with something interesting I can tune into again until I'm back off to sleep. Helps my sleep immensely. Rather than waking to worry about the stress ahead or getting back to sleep.

[@ishmiel21]

This doctor was one of my favorite guest you've had on in a long time. Her knowledge, joy, optimism, and imagination were such a pleasure to listen to. Thank you for bringing this amazingly intelligent person into my sphere of knowledge.

She sounded like a cross between a reader at a kids library and a yoga instructor. :) Is that a slight German accent?

[@ishmiel21]

[@ishmiel21]

@@blubard6105 What the hell are you going on about? Who's entitled? It sounds like you think all smart people have to sound like soggy old people. Heaven forbid a scientist finds joy in their work and expresses that joy when they speak. I'd really love to know what your problem is.

[@8PMFORMULA]

Sbe is annoying . Why does she speak with such phony fake enthusiasm?

[@laurencemoore3042]

I can see why she has been given Carl Sagans old office as her sense of awe and wonder is palpable and infectious. A super guest and I really enjoyed this episode. More please.

[@rodfaragini7110]

Love the enthusiasm of Dr. Lisa. So easy to listen to with her calming voice on a fantastic subject.

[@adambrain8365]

Sixteen minutes in and can already tell fantastic guest. I don’t know how you get such genus and charismatic guests. Whatever we’re doing everybody, run this train until it runs off the tracks.

[@adambrain8365]

Genius*

[@Kocan7]

Dr Lisa has absolutely amazing voice, combined with her enthusiasm and how well she communcates her knowledge it's definitely my favourite episode in a while. Amazing guest, from a top of my head only dr. Kipping can rival her.

[@toddsmith8534]

Love listening to Lisa Kaltenegger

[@8PMFORMULA]

I don't. She sounds annoying with her fake enthusiasm.

oh wow, 5mins in, and I feel love listening to Dr. Lisa Kaltenegger

[@GeneFraxby]

Dr Kaltenegger has the voice of a storyteller, and that made this amazing. Thanks to you both.

[@DarkKitarist]

"I'm sitting in Karl's office right now" is such an awesome flex.

[@PrimordialOracleOfManyWorlds]

dr. Lisa Kaltenegger is so passionate about the video subject that i can feel an energetic vibe to make you watch the video enthusiastically. i love it. i love it. tyvm for posting this splendid video.

[@EventHorizonShow]

Well said!

[@RedGandalf]

Hearing someone with such a love and knowledge of her work is a real treat. I could listen to her talk about planets all day!

[@urbanshadow777]

Holly crap this was one of the best EH episodes I have ever listened to. Its like listening to audio Nyquil. Both John and Lisa have such soothing voices I can only imagine that this is how dogs feel when their owners go out and leave the radio on.

More of this please! Her positivity and your insight…. Guhh. This. More. Much love to all.

[@Haryazz]

Let me start off by saying I'm looking through a window that has the exact view of what Carl Sagan was seeing, is such an incredibly low key hard flex. Jealousy now fills my heart beat

[@HugeGamma]

Lisa's voice is ELITE

Wow I could listen to Lisa speak all day! 2 fantastic voices and super interesting discussion.

[@facestomp88]

Such a lovely voice to learn from. Her voice is very inviting and at the same time demands your attention, and she describes things in good ways as well. Nice mate 👍

[@anaguma90]

Thank you as always JMG! Lisa is a wonderful guest, a joy to listen to.

[@SympNerv]

I really enjoy listening to Dr Kaltenegger... she is a great speaker that seems to be able to convey the wonder she feels in her voice, not just her words...

[@cykkm]

You can _hear_ in Prof's voice how her eyes light up. And when your Prof's eyes light up, yours do too! She lectures a level 2 course in planetary astrophysics and herds two 4/6 IS courses. Ah, the happy few! Don't miss her Xwitter: there are both science-how about a stable 6-star system, a planet where CO₂ and H₂O rotate at different speeds (a liquid ocean?!!), Europa's iron core or the poor Ingenuity still working as a stationary observer and a future platform test-bed?-and art, and not only lesser known artsy PR images, but also space-themed paintings by one of her grads!

[@aprylvanryn5898]

That "Quark" star made me smile. Thanks for that

[@itsfonk]

Thank you, John and Lisa. I felt like I was out back relaxing with friends around the fireplace, stretched into one of the hammocks, slowly drifting off to visions of a splendid discussion. 😊🤙

[@MARILYNANDERSON88]

Very exciting guest, enjoying the enthusiasm

[@hollycook1419]

I adore this guest! Dr Kipping has a great interview with her on his Cool Worlds podcast too! Great interview John!

[@John-ou4rm]

I watched Carl Sagan documentaries as a child. His passion, empathy and wonderment is what made him a giant. I remember him with some numbers with zeros on them trying to give some numerical rationalisation of planets and thus the potential for life.... So many zeros.

[@travisgrant5608]

First heard of him when I saw him on the Johnny Carson's Tonight Show when I was a kid. I was fascinated by him and his explanations of science and space. Then when he hosted that "Cosmos" documentary on PBS I became a fanatic about science and space! Thank goodness for today's technology because we can still have him with us to hear and see besides reading his books!

[@brunov958]

I could listen to her for hours ❤

[@EpicFail1946]

Wonderful Episode John. Definitely Dr. Lisa Kaltenegger is one of my new favorite guests.

[@StevenBara]

JMG might have found his match. If both made a conversation with a constant back and forth, I'd only not be cold out in seconds because it was so highly interesting!

[@DavidEvans_dle]

The way Dr. Lisa Kaltenegger describe earlier alien Earth with fascination - is inspiring. While I (hear/feel) amazing -> death, amazing -> death, amazing ->death...

[@5chitzo]

I can not imagine anyone more suited to sit in Carl Sagan's office. She has the exact same allure when explaining. Can't wait to hear more from her in the future.

[@sighfly2928]

@@MrIamestrangeddon’t mean to sound offensive, but that’s a bit of a far-fetched question for this channel lol. That comment is more appropriate for channels like “Bright Insight”, you know, the channels who are comfortable taking anecdotal and subjective evidence and present it as fact, often accompanied by their own spin (as if it wasn’t far-fetched enough).

[@AnthonyGiallourakis]

Finally, some truly long form content from my favorite KZbin channel. Sweet! 🎉🎉🎉

[@vorticalhook5794]

“Are there other earths?” Is such a simple and short question, but it shakes me to the core.

[@utu1818]

In my opinion, to think that we sit on the only earthlike planet is impossible. With what is probably an infinite universe with more galaxies than grands of sand, im sure their or many of every size you can imagine. It is mind-blowing.

John, an excellent interview and audio 👍, a comment for the algorithm 😉

[@SPACERAYTHESAIYANWARRIOR]

I must ask this question so, the discovery of one of the planets orbiting a dwarf star assuming the planet survived the explosion of the star would it be possible that the dwarf star simply adopted a rogue planet?

I started re-writing my big SF. Novel in ‘91, finishing the TV-pilot manuscript in 99, by the time my setting had evolved into a post collapse star-system, still orbiting their White Dwarf star, two surviving gas giants (Xerxes and Daedalus) , each with a single inhabited (human colonized) moon; much closer in I left one “surviving” rocky world, now a blasted lava rock named Blaspheron. The gas giants had migrated inwards and were now well within the iron-rich nebula, the magnetic fields of which well encompassing their moons. That nebula is glowing with the dying light of their Star Solara, though a low level of lightning, never knowing a complete darkness. …until the (human) villains’ attack causes a “nuclear winter,” that is.

at about 22:54 discussing life on an explanet of white dwarf . . . in the far future could a star spanning civilization - even with sublight starships - build a Dyson Swarm there? They could if asteorids and comets survived or a gas giant remnant still with plenty of hydrogen. Life does need water.

[@ParameterGrenze]

I was really worried when she started using her talking-science-to-toddlers-voice, but about 10 min in you managed to bring her back to talk like a scientist again. I understand why scientists in a public outreach position are prone to do this, but it is off putting to me. The most fun I have is when your guests not only talk in scientific terms, but also just right out use their domain specific lingo as if we where all PHDs from their institute. Your channel is where I like to hear about new things, about the little specific things that those scientists have to figure out and what the current challenges are.

at about 52:16 discussing oxygen level . . . at about 36% too easy for ""forrest fires" so that's maximum but minimum? New rocks - plate tectonics / volcanism crreates minerals needing oxygen to form. That was the other contributor to the K/T (also called Cretaceous-Paleogene or K/Pg) extinction, the Deccan Traps, with SO2 and CO2 as well to mess with the climate even more.

[@idorion9096]

If there aren't other planets very similar I suggest that implies a very diverse make up of planets and that we are more likely to discovered life on planets not so much like earth.
