Cosmology: The Universe's skeleton sketched

Eric V. Linder1

Top

The deepest and clearest maps yet of the Universe's skeleton of dark-matter structure present a picture broadly in concord with favoured models — although puzzling discrepancies remain.

Astronomers use every resource at their disposal to construct an image of the Universe: from the microwave radiation of the cooling Big Bang, past the visible wavelengths of light seen by the casual viewer of the night sky, to the gamma-rays of the most powerful explosions of collapsing stars and ravenous black holes. They don't even have to see an object directly to detect its presence.
