Astronomy and Astrophysics is a peer-reviewed scientific journal covering theoretical, observational and instrumental astronomy and astrophysics. It was published by Springer-Verlag from 1969–2000, while EDP Sciences published the companion A Supplement Series. In 2000, the two journals merged, with the combined journal known simply as Astronomy and Astrophysics and published by EDP Sciences. The journal copyright is owned by the European Southern Observatory. Astronomy and Astrophysics was formed in 1969 by the merging of several national journals of individual European countries. These journals, with their ISSN and date of first publication are as follows: The publishing of Astronomy and Astrophysics was further extended in 1992 by the incorporation of Bulletin of the Astronomical Institutes of Czechoslovakia, established in 1947.

Planck finds no new evidence for cosmic anomalies

ESA's Planck satellite has found no new evidence for the puzzling cosmic anomalies that appeared in its temperature map of the Universe. The latest study does not rule out the potential relevance of the anomalies but they ...

New catalogue of 12,000 X-ray spectral lines

X-ray sources in the sky radiate "bar codes" revealing their properties. These bar codes consist of narrow peaks and troughs within the source's spectrum. The RGS instrument on the satellite XMM-Newton was built to find these ...

Eighteen Earth-sized exoplanets discovered

Scientists at the Max Planck Institute for Solar System Research (MPS), the Georg August University of Göttingen, and the Sonneberg Observatory have discovered 18 Earth-sized planets beyond the solar system. The worlds are ...

Spring on Pluto: An analysis over 30 years

Whenever it passes in front of a star, Pluto provides precious information about its atmosphere, precious because occultations by Pluto are rare. The survey achieved by researchers from Paris Observatory over several decades ...

Suppressed star formation in the early universe

Massive clusters of galaxies, some with more mass than a hundred Milky Way galaxies, have been detected from cosmic epochs as early as about three billion years after the big bang. Their ongoing star formation makes them ...

Rare-Earth metals in the atmosphere of a glowing-hot exoplanet

KELT-9 b is the hottest exoplanet known to date. In the summer of 2018, a joint team of astronomers from the universities of Bern and Geneva found signatures of gaseous iron and titanium in its atmosphere. Now these researchers ...
