Fire in the dark clouds

The Atacama Pathfinder Experiment (APEX) in Chile offers a beautiful view of clouds of cosmic dust in the group Orion. In observable light, this dense interstellar cloud appears dark and solid. The LABOCA camera on APEX, however, can detect the heat radiation emitted by dust and so do the hideouts of the just emerging star locate. One of these dark clouds is not what it seems.

Dense clouds of cosmic gas and dust in space are the birthplaces of new stars. In visible light, the dust appears dark and opaque so that it hides the stars behind. 

How can A Stars is growth

Spitzer will present significant information on the structure and growth of stars and the circumstellar medium (surrounding the star). The discovery and characterization of circumstellar disks of gas and dust, signs of extra-solar planetary systems is one of the most important scientific goals of the Spitzer mission

Molecular gas

The giant molecular clouds are composed primarily of hydrogen, are the reserve materials from which stars form. 

The United States could be causing the increase in the number of earthquakes

The dramatic increase in oil and gas in the United States could be causing the increase in the number of earthquakes in that country.According to the conclusion of an investigation by the U.S. Geological Survey, the number of earthquakes has increased six times. In just three years, increased the number of earthquakes from 50 in 2009 to 134 in 2011.

Experts say some tremors may be caused by the hydraulic fracturing method. This involves injecting a fluid mixture into the ground to cause the release of natural gas, or oil .

An asteroid impact with Earth of Consequences

Geological studies conducted over the last decades have shown us that our planet has undergone a similar meteoric bombardment suffered by the Moon, and even more intense. In fact, due to its greater gravity, the impact rate on Earth is 1.5 times higher than our natural satellite. 

The size range of objects striking bodies is between a few meters to others of several kilometers across, and producing very different effects of different factors: the diameter of the shock, their speed, their density, the place to occur impact either on sea or land, etc.. An example of this was the "Tunguska Event" which little impact (June 30, 1908) has gone unnoticed, because it took place on a spot on the planet virtually underpopulated. What would have happened if the case occurred on an urban or densely populated area?
