I love Dr. Kipping's attitude when experts say something can't be done because it's too ambitious or unrealistic. Whether it's childhood dreams, finding exomoons or using the solar gravitational lens as a telescope, the only appropriate response to doubters who tell you not to pursue these grand ventures is "well, bollocks to that" as he said in a previous video. Keep up the amazing content, sir.

Jackson already has a better understanding of the Universe than 50% of the adults I know. Thank you, Doctor! You've never put out a video from which I've not learned something. Always enjoyable, Sir.

When I first heard of galactic habitable zones, I remember it being about background radiation from the stars in an area so dense, that it would be difficult for life to begin.

I have to admit, I'm not the brightest when it comes to astrophysics, quantum mechanics, and the science realm in general. But channels like yours have really helped me to pique my interest and keep me updated on various topics about the universe. It's respectable and something that all of us want - to make a difference.

Thank you Jackson for breaking down the Habitable Zone for us!

You’re telling me there are inhabitable parts of the galaxy right now?

Baby Kipping is my new favorite astronomer.

G'day Prof. Kipping! 👋 I'm currently completing my BA of Archeology. As part of my archaeology degree, I'm doing some electives in Astronomy, as not only is it a personal passion, but ties into archaeoastronomy; which can be used in some regards to give further insight into ancient cultures. The other week I was privileged to take part in a public lecture with Dr. Jessie Christiansen, who is also researching exoplanets and who I believe you may be familiar with. I just wished to express my heartfelt gratitude for people such as yourself and Dr Christiansen who share this knowledge and passion with the rest of us in our pursuit of understanding our cosmos. The idea of supernovae playing a part in extinction events is something I also consider as a budding archaeologist. When i hear your sign off words in these videos, I am always reminded of the late Carl Sagan and the same values of knowledge, curiosity and love he shared with the world. Thank you 🙏

I'm about halfway through buuuuut I'm gonna have to rewind back to the beginning. Because everything after David showing off how clearly proud he is of his son, Jackson, has gone through one ear and out the other.
It was just so sweet, and I know I'd be beyond proud too 🩵

I really appreciate your calm, level-headed approach to this stuff. I am SO tired of channels making the dumbest clickbait titles full of lies and spreading a bunch of nonsense to people who don't know any better. So, thank you.

The only thing better than these informative and fascinating cosmological subjects is that they're so scholarly, professionally and stylistically covered and presented by Dr. David Kipping and his Cool Worlds lab!!
Please do carry on Dr. Kipping!! We never tire of your information, explorations and presentations.

Thank you for introducing us to Jackson! He seems super bright and even more curious. Jackson, you could be the first person to step foot on Mars! Keep looking up and wondering!

Love your guest expert, Jackson Kipping! ❤

I actually took an elective course in college called “Searching for Life in the Universe.” I absolutely love things like this, absolutely fascinating! We covered many of these same concepts, albeit on a more entry level.

If only I had people like him teaching me! hung on every word Dr Kipping you're a master communicator.

Do you know what the most frustrating thing is...? Being able to recognize and understand what is being discussed...but at the same time...being unable to remember what you have just heard. It is my unfortunate privilege to have once had a capable mind...but before I was able to do anything useful with it my brain came down with an extremely rare form of tumor that was about 1/5th my total brain in size. I had some incredible doctors...but there are some things that even skill can not overcome. The most frustrating aspect for myself though...the loss of languages. I used to be able to read and speak in...I think...eight different languages. Now I am down to only portions of english. Even food items in exotic tongues have lost meaning for me. Being aware of the incredible pace of advancement...but being unable to contribute to it myself. Even so, thank you for sharing these videos even if I will forget in short order having watched it.

This was a really cool video! When I was taking a senior level astrophysics course I did a project where I calculated metallicity changes in the sun if it was placed at the current location of the ejecta from SN 1987a using some basic assumptions. Even then the change was relatively small compared to the mass of the sun, so I’m not surprised that most of the galaxy is habitable in that regard. Seeing the galactic habitable zone when considering gamma ray events was quite terrifying in contrast to be honest.

I like our quiet neighborhood out here in the suburbs of the Orion-Cygnus galactic spiral arm. The core is too busy for me...

I wonder if we could scale this up to Universal Habitable Zones. Some galaxies are too big and have too many dangers, high rates of supernovae, and close encounters with other stars. Some galaxies are too small, with a low percentage of heavier elements needed for life. Some Galactic clusters have too many members that collide with each other, which could disrupt stars within each galaxies. Too few members might be a problem, with few galactic encounters that would not add new gas to existing galaxies. Just a thought, thanks for another great video.

Super job making this layman-accessible. You're a highly effective science communicator.
