Allesfitter: one code to fit them all
Over the last year I developed an extensive tool set that I bundled up in this public code, with the hope that it can be useful to fellow exoplaneteers and stellar astronomers. Read more.

TESS' first Earth-sized planet, HD 21749 (New York Times)
Unmasking hidden exoplanets with novel techniques
Measuring stellar light to 1/4000th image pixel precision

The Transiting Exoplanet Survey Satellite (TESS) is set to discover thousands of new exoplanets. Launched in April 2018, TESS now monitors millions of stars for temporary drops in brightness, which are caused by planetary transits. It will identify planets ranging from Earth-sized to gas giants, around a wide range of stellar types and orbital distances - and maybe even Earth 2.0.
MIT Space Exploration Initiative
With humanity at the cusp of interplanetary civilization, the Space Exploration Initiative (SEI) is actively building the technologies, tools, and human experiences of our Sci-Fi Space Future. In doing so, we build on the spirit of the Media Lab, uniting artists, scientists, engineers, and designers, supporting parabolic flights, suborbital and orbital launch research deployments, and a team of 50+ students, staff, and faculty.
The SPECULOOS mission (Search for habitable Planets EClipsing ULtra-cOOl Stars) consists of four Ritchey–Chrétien telescopes of 1-meter primary aperture, and is based in Paranal, Chile. It's prime mission is to study planets around the coolest of all stars, and find many more systems like the famous TRAPPIST-1 - which was discovered by the SPECULOOS prototype.
The Next Generation Transit Survey (NGTS) is an exoplanet hunter based in Paranal, Chile. With its 12 fully robotized 20 cm telescopes, NGTS covers a total field of view of almost 100 sq. deg. on the sky at once. The main goal of NGTS is to find transiting Neptunes that will be suitable for RV follow-up and mass measurements using current and future instruments such as HARPS and ESPRESSO.
