2: Exoplanets

First some background:

Technology development is progressing, you have probably read about it since 1992 when the first exoplanet was detected, today (2017) we have detected over 3500 planets around other stars than our Sun.

One technology is based on studying the Doppler shift arising from the star as the planet "pull" on it by gravity when they go into orbit. Most of the "new" Exoplanets has been discovered by the Satellite Kepler by monitoring the brightnees of stars and how it changes when a Exoplanet passing over the stars disc.

There are other things than studying the planets indirectly that is of interest. A very interesting area to research and study is the surrounding of the stars, including how our Sun's planetary system formed and evolved.
