Astronomers first observed dark galaxies in the early universe

Astronomers have observed first dark galaxy, an early stage of galaxy formation, said the European Southern Observatory (ESO) from its headquarters in the German city of Garching, to the south. The Scientists used the long-range telescope (VLT, for its acronym in English) Cerro Paranal Observatory in Chile, which managed to detect these gas-rich galaxies that do not contain stars, noting its brightness when illuminated by the light of a quasar.

Extensive before that scientists began to wonder about the origin of water on Earth . And so far the official maintained that the volatile elements (such as hydrogen, nitrogen or carbon), and even the first organic matter, arrived here from abroad , contributed by comets and meteorites by class of origin very old, the carbonaceous concretes . Both classes of objects are formed beyond the orbit of Jupiter and "migrated" then into the Solar System.

A large solar flare reaches Earth

The huge AR 1520 spot with a diameter ten times that of Earth, launched an X-flare 1.4, within the highest level in the intensity scale (there are A, B, C, M and X, points which is a number from 1 to 9). Whiplash has caused a coronal mass ejection (CME), a fiery cloud of particles and radiation that could affect Earth, as explained by the Space Weather Observatory.

The blaze has had consequences in South America, Central America and parts of the Caribbean, where there have been radio blackouts R2 level (high level).
