"Venus has heavy metal mountains"
Pues sí amigos: la ciencia demuestra que, como ya dijeran los Manowar en su álbum "Louder than Hell", el Heavy Metal fue creado por los dioses en una Edad primordial y de él está hecho medio Universo. La B.B.C. ha hecho pública la noticia y todo.
Para convencer a los pocos escépticos que queden, pinchen aquí coleguis:
Porsiaca una conjura de los posers y poperos del Mercadillo de Fuencarral provoca un sabotaje que desactiva el enlace, paso a copiar el contenido de la noticia a continuación, en la lengua de Shakespeare. Es demasiado lo que está en juego para la Humanidad con esta Revelación.
Venus has 'heavy metal mountains'
By Dr David Whitehouse BBC News Online science editor
The highlands may be covered in metal
The highlands of Venus are covered by a heavy metal "frost", say planetary scientists from Washington University.
Because it is hot enough to melt lead at the surface, metals vaporise and condense at cooler, higher elevations.
This may explain why radar observations made by orbiting spacecraft show that the highlands are highly reflective.
Detailed calculations, to be published in the journal Icarus, suggest that lead and bismuth are to blame for giving Venus its bright, metallic skin.
Bright hills
Frequently seen as a brilliant point of light in the evening or morning sky, Venus has been identified with beauty by many cultures. But the truth is somewhat different.
Although it is about the same size as the Earth, its closer proximity to the Sun means that it is a very different planet.
Its thick atmosphere - composed chiefly of carbon dioxide - gives it an intense greenhouse effect, whereby trapped solar radiation heats the surface of the planet to an average of temperature of 467 Celsius.
Also, its pressure is 90 times greater than that at the Earth's surface.
The only way to glimpse what lies beneath its opaque clouds is by radar, and several missions have carried our radar surveys from orbit, principally the Magellan probe which operated from 1990 to 1994.
Magellan's images astounded astronomers who were able to see the surface of Venus in detail for the first time. They showed the planet was covered in volcanic features, such as vast lava plains, fields of small lava domes, and large shield volcanoes.
But the images were puzzling as well. It appeared that parts of the highlands were abnormally bright, reflecting radar beams much better than lower elevations.
Several explanations were put forward ranging from the presence of a loose soil to a coating of metal - specifically, tellurium.
Lined with lead
The theory suggests at Venus's hot lower layers any metal would be vaporised and exist as a metallic mist. Only at higher elevations, where it is a little cooler, would that metal condense to form a thin, highly reflective layer on the ground.
Using detailed chemical calculations involving 660 metal compounds, Laura Schaefer and Bruce Fegley, of the Washington University in St Louis, conclude that tellurium is not responsible, but that common lead probably is.
The researchers estimate that the timescale for the coating of the Venusian highlands by metallic frost is somewhere between a few thousand and a few million years, demonstrating that it is an active process.
They point out that at the highest elevations on Venus there is evidence that the metallic frost is absent - possible evidence of weathering, they say.
If it were possible to examine these lead deposits, from a Venus lander craft, the respective abundances of certain atom types, or isotopes, could give astronomers an estimate for the age of Venus.

Memoria de mi abuelo sobre la Guerra Civil y la posguerra - BAJO ASEDIO 1 de octubre 2.008
He aquí el programa más especial de BAJO ASEDIO hasta la fecha a lo largo de sus 4 temporadas de existencia. Los estudios de Radio Enlace quedaron iluminados y honrados con la presencia de mi abuelo, Mariano, quien nos contó varias historias reales de la Guerra Civil y la resistencia guerrillera de postguerra. En concreto, habló acerca de la caída y masacre de Badajoz y la increíble pero cierta vida de Santiago el Guerrillero, ante quien toda novela o película palidece.
Prepárate, si reúnes ánimos, a escuchar un pedacito de la Verdad sobre la Historia reciente de España, ésa que siempre nos quien ocultar y tergiversar. Una trágica canción de gesta que nos muestra la lucha de un pueblo por salir de la oscuridad, el caciquismo y la superstición, y que una y otra vez en la Historia es abandonado ante sus enemigos.
