Read article 'Exoplanet hunters find rich planetary systems'
The time when isolated extrasolar planets were discovered is over, with the detection of two entire systems of six and possibly even seven planets orbiting nearby stars. These recent discoveries by tw...

The INPC 2010 meeting reveals a healthy and dynamic research field.
Read article 'Cosmic accelerators may be at work in the Milky Way'
Measurements by the Pierre Auger Observatory may provide evidence of natural nuclear accelerators at work in the local galaxy, the Milky Way.
Read article 'Colliding galaxies formed giant black holes'
Like Ben Johnson’s explosive jump out of the starting blocks for 100 m, the growth of supermassive black holes had a “jump start” in the early universe. What triggered this fast...

The first scientific results obtained by the Herschel infrared observatory have been published in a special issue of the journal Astronomy & Astrophysics. Based on data collected during the first ...
Read article 'X-rays reveal missing matter in hot gas'
X-ray observations suggest that about half of the ordinary, baryonic matter in the universe is in the form of hot, diffuse gas. The detection of absorption lines from the Sculptor Wall by the two lead...
Read article 'Fermi limits the intergalactic magnetic field'
Astronomers have found evidence that the magnetic field between galaxies cannot be negligible. Otherwise, a blazar observed by the High Energy Stereoscopic System (HESS, CERN Courier January/February ...
Read article 'Astronomers miss 90% of distant galaxies'
The rate of star formation in the early universe is mainly deduced based on a specific hydrogen-emission line observed in remote galaxies. It was already suspected that this Lyman-α line is stron...
Read article 'Gravitational lensing constrains cosmology'
When two sources at various distances happen to be aligned on the line of sight, the gravitational field of the nearer galaxy distorts the image of the distant galaxy into multiple arc-shaped images (...
