Examples of A-type exoplanet host stars are HR 8799 (e.g., Marois […]

First results on the Pluto system by New Horizons

More remarkable is the complex geology and geomorphology which characterize both Pluto and Charon. Pluto is by far a non-dead planet as resurfacing […]

Planetary imaging from Skinakas telescope

Although not aware of what problems to expect we finally didn’t encounter any (as Manos had been really working on this with great care and caution) but for the weather and seeing. So, […]
