Two weeks ago NASA has announced its new Nexus for Exoplanet System Science, which may prove to be a major change in the way NASA will fund exoplanet science in the future. Our UA-led team was part of the first selection and I, the principal investigator of our project, joined the program’s two-day kick-off meeting at…

The Best Astrobiology and Exoplanet Books
I am often asked to recommend books on astrobiology, habitable exoplanets, and extraterrestrial life. There are many great books in these exciting fields, but there are a number of stand-outs that I highly recommend. Below is a gradually growing list of my favorite ones. Is your favorite book missing? Add other book suggestions in the…
On to A New Year and New Exoplanets!
The 2014 year has brought much excitement in the field of extrasolar planets and 2015 is set to be at least as exciting as the past year: new powerful adaptive optics systems are searching the northern and southern skies for new exoplanets and Kepler2 should start bringing a large number of new planet candidates! Just…
Grenoble and Planet Hunting with Adaptive Optics
In July I spent four exciting days at the Institut de Planetologie et d’Astrophysique de Grenoble (IPAG). Set in a picturesque green valley in the Alps where the rivers Drac and Ilsere merge, this scenic little town in Southern France is well-known for planet hunters. The Grenoble group I visited is one of the world…
Saturn’s Super Storm
If you live in the US, you will remember the great February snowstorm of 2010 – which entered history as “Snowmageddon” – that covered the East Coast in thick snow and paralyzed cities and airports. It was one of the largest winter storms in recent history. Yet, the same year in the outer solar system…
Exoplanets in the UA Daily Wildcat
The University of Arizona’s Daily Wildcat has published a nice article by Zane Johnson on our work on rotational mapping of brown dwarfs and exoplanets. It was fun talking to Zane. Good luck with the new science desk at the Wildcat!
How to Get Your Own Exoplanet?
If you have been reading about exoplanets, you know that they all have boring names, such as GJ 876b, 51 Peg b, or WASP-19b (not to speak about the likes of KOI-762.02). Up to a few days ago the official names of exoplanets had to be the catalog identifier of their host star plus a…
The Wildest Clouds in The Universe
Flying on a Delta MD90 jet on my way back from Munich, Germany to Tucson among gorgeous towering clouds glowing in exotic shades of yellow, orange, and purple. Amazing view – especially interesting is the all the different clouds we see are made of water. How would clouds on exotic other planets look? Earth is…
The Coolest Exoplanet Imaged – The Discovery of GJ 504b
Exciting news for planet hunters: Working with the 8m Subaru telescope at Mauna Kea the international SEEDS team announced the exciting discovery of a new directly imaged planet – this new planet is exciting not only because very few planets have been directly imaged yet, but also because this one is different from all others…
