Stars are younger: 'Reionization' is more recent than predicted

The highly anticipated update of the analysis of data from the European Space Agency's Planck satellite starts with a first paper published in Astronomy and Astrophysics, which already holds in store a few major surprises. ...

Quantum foam

Quantum foam. It may sound like the name of a new craft beer, but it's something even more amazing.

The universe, where space-time becomes discrete

In quantum gravity, classical physics and quantum mechanics are at odds: scientists are still uncertain how to reconcile the quantum "granularity" of space-time at the Planck scale with the theory of special relativity. In ...

The kilogram gets a makeover

In Sèvres, a small commune on the outskirts of Paris, lies a gleaming lump of metal the size of a palm. Le Grand K, or Big K as they call the platinum and iridium alloy, sits underground in a high-security vault. It is held ...

Iron in the sun: A greenhouse gas for X-ray radiation

(Phys.org) —Scientists from the Heidelberg Max Planck Institute for Nuclear Physics (MPIK) in cooperation with DESY (Hamburg) at the synchrotron PETRA III have investigated for the first time X-ray absorption of highly ...

Image: The magnetic field along the galactic plane

While the pastel tones and fine texture of this image may bring to mind brush strokes on an artist's canvas, they are in fact a visualisation of data from ESA's Planck satellite. The image portrays the interaction between ...
