PICTURES: THE HORSEHEAD NEBULA

Publicado en Capital Letter No. 2

In this case, we propose astronomical photos for you to see; we hope you enjoy them. In this issue we introduce you to one of the most identifiable nebulae in the sky, the Horsehead Nebula in Orion. It is part of a large, dark, molecular cloud. The darkness of the Horsehead is caused mostly by thick dust, although the lower part of the Horsehead's neck casts a shadow to the left. Streams of gas leaving the nebula are funneled by a strong magnetic field. Bright spots in the Horsehead Nebula's base are young stars just in the process of form­ing. Light takes about 1500 years to reach us from the Horsehead Nebula. The image below was taken at Kitt Peak National Observatory.

CAPITAL LETTER 7: EDITORIAL

INDIFFERENCE IS THE NAME OF THE GAME Publicado en Capital Letter No. 7 Mayo de 2005 One of the questions we usually ask ourselves is why things are the way they are. There should be more peace, more security, more courses, more processes going on, more research, more changes… and endless list of other things. What are we doing to contribute to the construction of that better society we all envision and desire? Have we contributed in the creation and provision of peace, security, study opportunities or research processes for ourselves and the others? What has been our performance as individuals and as groups? What have our results been? The Universidad Nacional de Colombia is a place rich in human resources. Students and teachers have been given the chance to exchange and spread knowledge.
