Summary
NASA announces a three-month delay in the launch of its next exoplanet mission, now scheduled for December 2017. This adjustment is not seen as a cause for concern, as the ambitious timeline for the Transiting Exoplanet Survey Satellite (TESS) suggests that the project remains on track.
The discussion shifts to the legacy of the Kepler mission, which has significantly advanced the understanding of exoplanets. Kepler's groundbreaking work, which involved monitoring the brightness of 200,000 stars, led to the discovery of nearly 5,000 planetary candidates, with over 2,000 confirmed. This data suggests that there is at least one planet for every star in the universe, marking a profound shift in the perception of planetary formation.
Kepler's findings also revealed the diversity of planetary systems, challenging the notion that the solar system is the most common configuration. The mission identified new types of planets, such as mini-Neptunes, and confirmed the existence of planets orbiting binary stars. These revelations indicate that the architecture of planetary systems varies widely, contributing to a new understanding of the universe's structure. The speaker expresses excitement about being part of this transformative era in exoplanetary science.

There have been two scientific revolutions involving a "Kepler"- one 400 years ago and one on-going! Prof Kipping explains both and why NASA's Kepler Mission will go down in the history books as transformative.::More about this Video::► NASA's Kepler Mission website: http://kepler.nasa.gov► Burke et al.

Alien megastructures are back in the headlines after some new research published last week. It has been claimed that Tabby's Star is confirmed to be steadily dimming, which is completely unexpected behavior for a star. Prof Kipping explains what we know (and don't know) about this mysterious star and what astronomers really mean by "alien megastructures".::More about this Video::► Montet & Simon (2016), "KIC 8462852 Faded Throughout the Kepler Mission": http://arxiv.org/abs/1608.01316► Schaefer (2016), "KIC 8462852 Faded at an Average Rate of 0.165+-0.013 Magnitudes Per Century From 1890 To 1989": http://arxiv.org/abs/1601.03256► Boyajian et al.

The transit method of finding exoplanets is easier for big planets than small planets. But new work from the Cool Worlds Lab shows that transits disfavor the detection of small, Earth-sized planets even more than previously realized. Emily Sandford, a third-year graduate student with the Cool Worlds Lab at Columbia, explains our new paper which derives these biases, allowing astronomers to correct for these effects when figuring out how many Earths there really are.::More about this Video::► Kipping & Sandford (2016), "Observational biases for transiting planets": http://arxiv.org/abs/1603.05662► Outro music by Taylor Davis: https://www.youtube.com/watch?v=dl9kI1yQKZk::Playlists For Channel::Latest Cool Worlds Videos ► http://bit.ly/NewCoolWorldsCool Worlds Research ► http://bit.ly/CoolWorldsResearchGuest Videos ► http://bit.ly/CoolWorldsGuestsQ&A Videos ► http://bit.ly/CoolWorldsQAScience of TV/Film ► http://bit.ly/ScienceMovies::Follow us::SUBSCRIBE to the channel http://bit.ly/CoolWorldsSubscribeCool Worlds Lab http://coolworlds.astro.columbia.eduTwitter https://twitter.com/david_kippingInstagram https://www.instagram.com/cool.worldsTHANKS FOR WATCHING!!
