Astronomers have exposed the largest structures in the universe

A group of British astronomers exposed the largest known structures in the universe. This is a group linked by a single gravitational field of active galactic nuclei, which make bigger from one end to 4 billion light years away. Scientifically verbal communication, the structure is a large group of quasars.

ALMA makes gas flows visible on the planet formation

Astronomers using the Atacama Large Millimeter / submillimeter Array (ALMA) for the first time to directly observe how extensive gas streams overcome a gap in the disk of matter around a young star. In theory, should such gas streams arise during the growth phase of planets? This is a key stage in the birth of the gas giants. The observations are the second January 2013 published in the journal Nature.

New View of the globular cluster 47 Tucanae

Globular clusters 47 Tucanae are huge spherical cloud of old stars held together by gravity. They are turning around the cores of galaxies, and satellites orbiting Earth. These groups of stars contain very little gas and dust - it is believed that most of the cluster has been driven by winds and explosions of stars it contains, or has been torn by the interstellar gas has been interacting with the cluster. Any remaining material coalesced into stars billions of years ago.
