Optical frequency comb allows more accurate astronomical observations

Solar Orbiter (ESA) will travel around the Sun to study both solar physics and the Sun’s influence on the interplanetary medium, using instruments of local measurement as well as remote surveyal

GLORIA, which uses copyleft licenses for the free distribution of its contents and materials, is supported by the Ciziten Science program of the European Union

Apart from very distant, ultraluminous quasars -evolving rapidly and associated with galaxy mergers - there is likely another population of quasars that evolves slowly

The second data release of the international project CALIFA - a survey of galaxies carried out at Calar Alto observatory – will take place today

Young star HD169142 displays a disk of gas and dust with two annular gaps possibly due to the formation of planets

Study discards possibility that type Ia supernovae might stem from explosions of white dwarfs nourished by normal stars. Were these conclusions to become generalized, type Ia supernovae might no longer serve as “standard candles” to measure astronomical distances

Comet 67P/Churyumov-Gerasimenko, destination of ESA’s Rosetta mission, seems to consist of two parts

Venus’ atmosphere rotates up to sixty times faster than its surface, a phenomenon known as superrotation whose origin hast yet to be satisfactorily explained

Imaging at optical/infrared wavelengths is a novel technique that has been developed during the last ten years
