How do we discover more exoplanets? Neil deGrasse Tyson and comedian Matt Kirshen explore telescopes, exoplanets, and more with professor of astrophysics and Principal Investigator of HATNet Exoplanet Survey, Gáspár Bakos.
At what rate are we discovering exoplanets? Learn about the HATNet and how ground telescopes are helping the search for exoplanets. Learn how light detectors find their subjects and how low earth orbit objects impact exoplanet detection.
We discuss the difference between light pollution and light pollution from satellites. Discover models of what starlink will look like in the night sky and what simple ways we could decrease light pollution. Also learn first-hand the ways that astronomy is being impacted in the age of proliferating satellites.
Could an exoplanet have life like us in a binary solar system? What can we learn about exoplanets using their transits? We discuss biomarkers, planets without stars, and how many stars we have access to. Plus, could we someday use gravitational waves to detect exoplanets?

Not a fan of matt… to be honest I can’t watch it if he is on the video. I love all the videos that Chuck is on. The banter between Neil and Chuck is so much more natural.
Yeah, Starlink is moving forward because of it's military utility, no astronomer is going to stop that.
Great episode! Thanks!
If there was no business case for Satellite internet, they (Starlink, OneWeb, etc.) would not be building satellites for internet coverage. So I'm not sure I agree that almost everyone has useable internet. The Demand or need is there.
Fun fact: I'm from Nigeria but from the defunct Eastern Region now known as the South East. The North East of Nigeria has been ravaged by Bokoharam insurgency in recent memory so I completely understand when NDT shouted wow 😲. Here's hoping that peace 🕊️ returns back to the region. The whole world needs it
Yesterday neil sir meet with prime minister of india pm modi
Would it be possible that a binary star system rotate like the axel of a top with the planets rotating around this axis? That would be interesting.
Cosmic Queries without Chuck is like The Beatles without Ringo Starr 🙁
I love hearing people living in cities saying that starlink isn't needed. I live in the country and Starlink is the only available broadband internet. And it would be very expensive to supply me with anything other than satelite internet here in Rural Quebec
“We will just find an uninhabitted planet to camp on!” – “Major Sheppard, we both know they are uninhabitted for a reason!”
Completely unflappable! Brilliant
where's Chuck
Neil thank you we Love you!
Hey Neil, I have a potential discussion topic for you to cover if you haven't. I caught an article about the damage to our retinas from 'BLUE' energy photons, the history of LED light, and how we developed a blue emitter. our eyes have not yet adapted to direct blue light, only reflected, and macular degeneration is the result. And am I an idiot when I turn on the lamp when my sweetie is playing on her tablet at night, and wakes up with bleary eyes?
Where is Chuck!? 👎
How come light does not accelerate, but jumps instantly to the max speed?!
Yeah, that thing your iPhone does with all those varying exposures is called an HDRI (High Dynamic Range Image). We've been using that in VFX and photography for about 20 years now. You can take an HDRI of a mirror ball (like you use in a garden) and get all of the lighting information for adding CGI to a live action scene and in photography you can eliminate hot spots and/or dark spots by adding in the details from the exposures that accurately capture those areas of the photograph.
Who is we Tyson. 😂😂 I am in Namibia & the night sky is still lit 🔥
How do or did we pollute our atmosphere with a gas that is heavier than air? Freon doesn't float up in air.
Does Gáspár Bakos have a Scandinavian accent? I tried to google his ethnic background but failed
Thanks for inviting Lars von Trier
The comedian was the only one that looked like they actually wanted to be there.
wouldn't any data collected about exoplanets be outdated by millions or even billions of years?
Yeah, but what can we find out about Endoplanets?
How are they working on raising the resolution for distant exoplanets etc?
Are you ever going back to all being together i one room again?
Is he Hungarian? 😁 Huge hi5 from Hungary!
This is so out of date. Where the local government has switched to better designed street lighting any gain has more than been (vastly) overwhelmed by the stuff added to homes, gardens, and businesses. Even vehicle lights have become seriously brighter. The capacity of people to create problems for people hundreds of yards away is now cheap to install and run. It is going to get much worse.
However LIGHT POLUTION may annoy astronomers and hamper their work, but it is a serious problem for the natural world. Nature needs the night. There is a price to pay.
Yeh, there seems a phase between these archz that produces moisture!
I can’t believe Neil knew about the way iPhones take pictures! As a tech nerd I only though us nerds knew about it but Apple calls it “Deep Fusion”
always nice to see a Hungarian face in science, hurray for Gaspar 🙂
Could a planet have a figure 8 orbit around binary stars?
Where’s Chuck?
Matt is annoying
"…they have no star, you know you have some weird civilization somehow developed those planets…" Sorry here I quit the show.
So years ago I was driving transport truck through Pennsylvania at night in the rain and a deer leapt out real close and I hit it. I was being tailgated at the time and the car behind I think was doing it because of all the deer in the area. Anyways it passed me all covered in blood. I straightened my bumper and continued on, kind of paranoid and trying to look extra hard. So a bit later I saw in the oncoming headlights a deer standing on the road. As the car got closer, the deer tried to jump off the highway and fell down. Twice, before it finally got off the road. I decided this meant the rain was turning to ice so i coasted to a slower speed and looked for a place to park. That's the first time I actually used the principle of a transit for a practical purpose. Birdwatchers count the birds transiting the full moon per hour and multiply by 347.4 to estimate nightly migration populations. I wonder if all the extra satellites will affect this. A great episode, lovely guest!
It's cool because the Tureans in mass effect. Have the same type of telescope set up in the cosmos. With a bunch of small telescopes placed away from each other. Connected threw sub space. May be sifi but that's where radio or binary light pulses come in. To transmit data giving a lense of over 100 light years. We do this on earth with multiple telescopes in different contenents all swinging to the desired space when the earth turns. So there is always more than 3 sucking in light.
I want to know if neil likes mass effect
Do you think we'll ever find an exoplanet with life like us? Are we truly alone in the universe, or are there other inhabited planets that we haven't discovered yet?
Can you see plantlife from space? like is earth green from space or are those renderings. Planets closer to the sun might have some type of "plant" life that asorbs more blue light and planets farther away will have them asorb more red light.
*Planets*. The word you're looking for is planets.
Exoplanets are the outer planets of a given star system. Hence the name.
If the planets in question are extra-Solar ones, you're free to specify that.
Yo for a second I thought it was David Duchovny I.e Fox mulder from X files !
Awesome as always. Thank you for the info, and for bringing it to a level in which we are able to understand.
