NEWS!! Discovered the light of a "super-earth" out the Solar System.

The space telescope Spitzer of NASA has detected for the first time the light of a "super-earth", called "Cancri 55 e" with infrared light. It's localized in the solar system of the star "Cancri 55", relatively "near" us, at 41 light years.

That is a historic moment because it opens another way to search life in other planets in space. The spaceship is very speciallized in the study of far atmospheres, and this technique can be used now in habitable planets.

The "super-earths" are bigger than our planet but are lighter than others, like Neptune. Cancri 55 e has the double of size than The Earth. It's covered of water (liquid and gas) and revolves around a sun.

Middle Cancri 55 e is always dark and the other part is always illuminated. This part is over 2000 grades Kelvin, then there metal can be melted!

NEWS!! First photo of an albino killer-whale!

A group of russian scientifics have photographed for first time a strange specimen of killer-whale, and albino one, at the north of the Pacific, at the east of the Kamchatka peninsula. It's name is Iceberg. (So cute, don't you think? ^^)

The killer-whale was seen with a group of twelve other killer-whales, in one of the biggest reserve of Russia. The photos have been published in this webpage: Russian Orca.

"Now, Iceberg is a symbol of all the things non discovered, pure, wild, fascinating and exciting that the ocean has." said Erich Hoyt director of Far East Russia Orca Project (FEROP). "The objective is to keep nature and the oceans healthy because all this kind of surprises could happen."

In my opinion, this is a very fascinating discovering, and makes me realize that all I want to do in my life is fight for nature, keep it calm and pure, make no one kill her, don't let no one dirty my home.

NEWS!! ...Right to water...?

http://www.righttowater.info/why-the-right-to-water-and-sanitation/

Water and sanitation have been formally recognised as human rights as they are indispensable for the full enjoyment of the right to life, the right to health and the right to dignity.

However, as recommended by the Independent Expert, there is a process underway to recognise water and sanitation as individual rights. The protection and fulfilment of the rights to water and sanitation requires specific measures, and therefore should be fully recognised as autonomous human rights.

All human beings depend on a daily amount of safe drinking water for consumption, personal hygiene and subsistence, and on a hygienic and dignified method for excreta disposal to avoid disease.

------------------------------------------------

In my country this situation is completely different: we all have water to wash, to clean, to drink and to swim and play with it. It's so current to have water in developed countries that we don't think about it too much, and we waste water again and again. It would be better if everyone of us would save some water, also because we're going on a very hot age with climatic change.

In Africa, there's so many people that can't drink potable water, and have with this lack of hygiene malaria and other dangerous diseases that wouldn't be there if the right of water and sanitation would be entirely respected and accomplished.

We possibly can't do so much to solve the problem, but I'm sure that if we all together save water, and we're careful about this aspect we surely can solve the problem of zones that are so dry. People then, could drink and satisfy, a little better, their essential needs.

NEWS!! Birds & butterflies... affected for the climatic change.

The climatic change makes terrible and powerful variations at the global distribution of plants and animals, but there aren’t effects at long periods of time, yet. This has worsened the task of discovering how every taxonomic group is affected for those changes and what the real consequences are.

“A specific type of organism is adapted to its environment, and this provides it the optimum conditions for his metabolism, diet and reproduction.” explains the biologist of the study Constantí Stefanescu, of the Natural Science Museum of Granollers. “If the temperature changes, animals have also to make it at the same time and speed, but they usually can’t do it. This is told Climatic Debt.”

During two decades the climatic change has been studied and its consequences for 9.490 comunities of birds and 2.130 of butterflies around Europe. Between 1990 and 2008 the European temperature has displaced 250 km north. The bird’s comunities only moved 37 km since then and butterflies moved 114 km.

And the adaptative answer to the climatic changes depends of a lot of factors, for example, the landscape barriers and the characteristics of every type of specie. “Birds are slower than butterflies because their vital cicle is longer, and the poblational response is slower.” says Stefanescu.

The results of the study are really important because the climatic change is what really matters (in general) and also that if some species are affected for the climatic change, all the food chain would be totally affected.

HIERRO: Volcanical activity!!

The Canary Islands Government has raised the alert level for the El Hierro volcano in the Canary Islands to 'Yellow'.

Spanish seismologists, held a press conference on Sunday to communicate to the 10,000 residents of the smallest of the Canary Islands that the raising of the alert level does not indicate that an eruption is imminent. They indicated, however, that the number of volcanic earthquakes detected beneath El Hierro continues to increase.

Hierro, a shield volcano, has had a single historic eruption from the Volcan de Lomo Negro in 1793. The eruption lasted approximately one month and produced lava flows.

The Canary Islands Government commenced an in-depth geological survey of El Hierro earlier this month in an effort to determine the source of an earthquake swarm.

The unprecedented seismic activity commenced on 19 July. In excess of 7,000 earthquakes have been recorded up to Monday, 26 September 2011. More than 50 earthquakes were recorded between midnight and 6:00 a.m. GMT on Monday. The earth tremors have ranged between 1 and 3 magnitude.

The vast majority of the tremors have been recorded in the northwest island at El Golfo, the location of a massive landslide that created a 100-metre high tsunami almost 50,000 years ago.

Speaking to the El Pais newspaper during the weekend, volcanologist Juan Carlos Carracedo suggested that an eruption on El Hierro would "not be a major surprise".

He explained: "It is the youngest of the Canary Islands. There is a ball of magma which is rising to the surface and it is stationed at the limit of the earth's crust. At the moment we do not know if that ball of magna will break the crust and cause an eruption."

Earthquake swarms are events where a local area experiences sequences of many earthquakes striking in a relatively short period of time. The length of time used to define the swarm itself varies, but an event may last for days, weeks, or months.

El Hierro is situated in the most southwestern extreme of the Canaries. The island was formed after three successive eruptions, and consequent accumulations, the island emerged from the ocean as an imposing triangular pyramid crowned by a volcano more than 2,000 metres high.

Although over 200 years have elapsed since the last eruption, El Hierro has the largest number of volcanoes in the Canaries with over 500 open sky cones, another 300 covered by the most recent outflows, and some 70 caves and volcanic galleries.
