Read article 'Galactic map sheds light on dark energy'
The map shows galaxies being pulled towards each other by dark matter, while on much larger scales it reveals the effect of dark energy ripping the universe apart.

The European Extremely Large Telescope (E-ELT) will be the largest optical/near-infrared telescope in the world.
Read article 'Neutron-star mergers create heaviest elements'
While core-collapse supernovae were thought to be the prime production site, a new study suggests that elements heavier than zinc originate from the merger of two neutron stars.
Read article 'Protons accelerated to PeV energies'
The HESS collaboration has now found evidence that there is a "Pevatron" in the central 33 light-years of the Milky Way.

The CALorimetric Electron Telescope has observed more than a hundred million events at energies above 10 GeV.
Read article 'Fast radio bursts reveal unexpected properties'
Two studies show that fast radio bursts (FRBs) have a richer phenomenology than initially thought and might originate in two different classes.
Read article 'Gamma-ray excess is not from dark matter'
Two research teams found that the gamma rays of the excess emission at the galactic centre are not distributed as expected from dark matter.
