startswithabang:Exoplanets: From Fluke To Fact“In the last decades, exoplanets have become one of the most rapidly developing research areas in physics. One of the biggest lessons we have learned is that planetary systems like ours are much more common outcomes of stellar formation than had previously been expected. The properties of distant solar systems can now be measured to a precision high enough to let physicists infer properties of the planet’s atmosphere and to index any new planet for potential habitability. Yet even with all we’ve discovered to date, we’re only just beginning to understand what else is out there.”With the big news about Proxima b and Kepler’s haul of over 3,500 new planets since its launch, the idea that planets orbit stars other than our own is so mainstream that the alternative seems crazy. Yet from the 1950s through the 1990s, the situation couldn’t have been more different. A myriad of claimed detections – followed by press releases and failed follow-ups – led to exoplanet studies being considered an illegitimate scientific area of inquiry. Yet the early stories of discovery and the advances in the radial velocity technique not only paved the way for the rich scientific field we have today, that very method is indispensable for exoplanet confirmation. We’ve come so far that today, even the reverse of a transit, where a planet dips behind its parent star, can be detected.Come let Sabine Hossenfelder take you on the journey of how exoplanets went from fluke to fact over an incredible few years! -- source link
