The Golden Age of Exoplanet Exploration (live public talk)

Original air date: March 14 at 7 p.m. PT (10 p.m. ET, 0200 UTC)

Since the discovery of the first exoplanet orbiting a sun-like star in 1995, several thousand more have been discovered. We’ve peered into the atmospheres of some, and we’ve found whole families of planets orbiting strange stars -- many in configurations starkly different from our own. We’ve learned a lot from NASA's Kepler mission, which launched 10 years ago and ceased operations in November 2018. A new NASA planet-hunting spacecraft called TESS, which began science operations as Kepler was winding down, will give us thousands of new discoveries in the coming years. And the Spitzer Space Telescope has provided us valuable insights into what these worlds might be like. This show will look at the state of exoplanet science and give us a view of what future discoveries may be around the corner.

Speakers:
Jessie Christiansen, Research Scientist at the Caltech/IPAC NASA Exoplanet Science Institute, Caltech
Karl Stapelfeldt, Chief Scientist, NASA Exoplanet Exploration Program Office, JPL

This was a fantastic discussion. Thank you everyone who asked great questions. I had a fantastic time tuning in, see you next month.

[willinwoods]

Sound and image out of sync for me, with the image lagging behind by approx 2 seconds.

[ratatataraxia]

The fact that you can measure the composition, wind speed and temperature of exoplanets still blows my mind. 🧠 💥

[jayprakashs.chauhan]

Really, exciting & informative discussion.

[rositaayulaura]

I searched google for exo boyband without realizing exo planet OMG

[jacobboyle]

Great talk. Space exploration is truly entering the golden age and I'm glad ill be around to watch it

[ratatataraxia]

As always, thank you NASA and keep up the good work!

[treefarm]

Fantastic talk, and Jessie is a Queenslander!

[BoomedYetLush]

That was such a great presentation - thanks to all. I like the idea about the metal-poor host star study - I look forward to reading the papers. And what of the statistics on the metalicity of stars with protoplanetary nebulas?

[Tokolyser]

JPL resp. NASA never answered me to a vital question: Why do some of your astronomers on the document channels claim that the destruction of Cassini was mandatory not to contaminate the planet with microbes, whereas the Cassini-Huygens probe, including a parachute, decended on Titan. The one and only other planet with fluid in our solar system.
Same question applies for all the stuff left on Mars. It contradicts NASA's own rule of planatery protection entirely “to preserve our ability to study other worlds as they exist in their natural states; to avoid contamination that would obscure our ability to find life elsewhere — if it exists; and to ensure that we take prudent precautions to protect Earth’s biosphere in case it does.”

[АлександрНиколаев-нц]

It would be interesting to find out, in connection with the latest news from Nasa and new Moon programms, whether plans are being developed to build the Lunar Observatory? And how much more effective will it be than on Earth, or do you need to fly away?

[pumpuppthevolume]

man the amount of data we'll get about exoplanets in the next 10 years is going to be like an exploration of data

[samthegreekboy]

you aint seen nothin yet. Hugh Ross is also a PHD scientist Astrophysicist Astronomer from Cal. Tech and he is absolutely the bomb.

[gumnaam]

What year it will it be when finally alien life will be found?

[j.hanleysmith]

Starts at 10:15 I guess they are better at building rockets than editing videos!

[charlespelletier]

Sound sync reminds me of an old karate movie. Great info though.

[blackout]

Nasa what are your plans for the future

[anotherworld]

Кто понимает расскажите о чем речь. Интирестно очень

A Matemática andando na contra mão; com nome, sobrenome e denominação de origem, o passado jamais esteve tão presente por dentro da Ciências Exata, sendo a pioneira entre os pensadores e os(as) Matemáticos(as) em tempos passados, pois foi em cima de ombros de gigantes que enxerguei o horizonte na visão da Matemática, com esta grande única e majestosa descoberta sobre este enigmático número de "Pi", uma descoberta inovadora, com duas casas depois da vírgula uma medida com total precisão para os cálculos de "Pi", onde poderá mudar a história da Matemática, trazendo uma realidade acima de qualquer suspeita, provando Matematicamente que com sua precisão será uma descoberta inovadora no quesito Matemática, onde irá facilitar a explorar o espaço e o Universo, enviando sondas para todos os planetas jamais descoberto, e trazendo grandes informações de como um planeta é habitado, simples, preciso de uma simples razão para ter uma precisão jamais vista em todos os tempos, com muita investigações, muitos estudos e pesquisas cheguei ao um único número de "Pi", sendo totalmente Racional com várias razões de números inteiros e 270 fórmulas para seus cálculos, pois cada fórmula desenvolvida, tem que saber sua essência para ser tão bela com resultados surpreendentes.O Autor Sr Sidney Silva.

If they are looking for exoplanets, earth like or not, that is nice, if they are looking for planets that might harbor life, even just bacterial life there would be no sense in looking at the planet itself, looking at the star is sufficient to know. No sense in looking at a star to find planets that might harbor life if the galaxy is not the right kind of galaxy in a cluster of galaxies that will harbor a star that might harbor a planet with life. No sense in looking in the wrong kind of cluster of galaxies too. see what I'm getting at?
