100 Million Exoplanets By 2050? How Will We Get There?

TL;DR

By 2050, we could know of 100 million exoplanets using advancing techniques and telescopes.

Transcript

as I'm recording this video near the end of 2019 the total number of confirmed exoplanets stands at four thousand 104 we've come a long way since the discovery of the first exoplanet orbiting a sun-like star back in 1995 with 51 pegasi B and the reality is that the race to find new exoplanets is only accelerating new ground and space-based telescop...
