We want to raise interest for   this interesting field of research,     maybe even raise enthusiasm.   External guests are cordially invited as well.[[BR]]     [[BR]]     Parts 1 - 4 took place in the last semester ([https://intranet.mpia.de/intranet/en/lecture-series all recordings can be found here]).  In Part 5 and 6 of the lecture series the stars have been discussed. In this week's episode Markus Feldt will introduce planets and will take us on a journey featuring the search for exoplanets.[[BR]][[BR]]Presentation: German[[BR]][https://intranet.mpia.de/intranet/en/lecture-series Slides/Recording: German] [[BR]]Questions: German, English ||

A  novelty aboard is a powerful coronagraph system capable of direct  imaging of exoplanet systems in reflected starlight at very high  contrast ratios. The successful demonstration of such an instrument in  space will pave the way to a future space missions aimed at imaging and  characterizing faint Earth-like planets. [[BR]] [[BR]]MPIA is contributing six precision alignment mechanisms to the mission  which are essential to control the optical beam in the adaptive-optics  coronagraph instrument. All of this space hardware was designed at MPIA  and significant parts are currently being produced at MPIA's mechanical  workshop. The talk will describe the developments and tricky details of  the mechanisms, the project setup at MPIA, and the story behind a  successful collaboration with NASA's Jet Propulsion Laboratory in Pasadena.[[BR]][[BR]]Presentation: German[[BR]]Slides: English [[BR]]Questions: German, English ||
