BUENOS AIRES The stunning Perito Moreno glacier begins its breakup

The phenomenon is caused by the pressure of water above the ice dam begins to crack to form a gap that weakens

BUENOS AIRES The stunning Perito Moreno glacier begins its breakupBUENOS AIRES, March 2. – The stunning Perito Moreno Glacier in southern Argentina, has begun the process to its cyclic rupture, a show that attracts thousands of tourists, official sources confirmed today.

The ice dam that separates the Rico and the Canal arm of Lake Argentino Icebergs began tracking leaks on Wednesday and is expected in the coming days will produce its thunderous break. Media reports began to settle on the runways of Los Glaciares National Park in the southern Santa Cruz province, where the glacier can be seen waiting for the big show.

Sources of the Secretariat of Tourism of Santa Cruz told Efe that while the rupture process began Wednesday, and visitors began to arrive to the area and greater influx is expected in the coming days.

The director of the Los Glaciares National Park, Carlos Corvalan, told local press that the rupture could occur between Saturday and Sunday and reported that the reserve will be open for a extended hours. The phenomenon is caused by the pressure of water above the ice dam, which begins to crack to form an arch-shaped hole that ends up weakening and collapse.

The last rupture occurred in 1988, 2004, 2006 and 2008. For the imminent rupture is expected that the number of visitors to Glacier National Park, in the summer season is usually around 2,500 people per day, double this weekend.

The Perito Moreno, about 200 square kilometers extension is located on the Andes, the natural boundary between Argentina and Chile, and is one of the few in the world that is stable without flinching as a result of global warming. The front of the glacier is about 2.8 kilometers long and has a height of 70 meters above water level of the lake, although the ice wall reaches his bed.

molecular oxygen detect in the atmosphere of Saturn’s icy moon

Oxygen detect in the atmosphere of Saturn‘s moon

This concentration of oxygen is equivalent to that of the atmosphere of the earth at an altitude of 480 kilometers

Oxygen detect in the atmosphere of Saturn's moonWASHINGTON, March 2. – The Cassini spacecraft has detected a low oxygen concentration in Dione, a moon of Saturn, indicating that it has a tenuous atmosphere, although much less dense than Earth, NASA said today.

“Cassini has sniffed molecular oxygen ions in Saturn’s icy moon Dione for the first time,” said in a statement of the mission team.

However, the oxygen ions are widely scattered, one for each 11-cubic centimeters, which makes this concentration equivalent to that of the earth’s atmosphere at an altitude of 480 kilometers.

“We now know that Dione, like the rings of Saturn and its moon Rhea, is a source of oxygen molecules,” said Robert Tokar, a member of the Cassini mission at Los Alamos National Laboratory.

In his view, this finding confirms that oxygen is common in the Saturn system of moons and may originate in processes not involving life forms.

Oxygen, a basic element for life on earth where its concentration is the atmosphere, is about 21 percent, could originate from the moons of Saturn due to solar photons or energetic particles strike the surface of ice water satellite.

Scientists thought that Dione, due to its small size, could hold an atmosphere, and makes new discovery in this small satellite, an object of study much more interesting.

The Cassini probe, launched in 1997, is a mission involving NASA, the European Space Agency (ESA) and the Italian Space Agency which aims to study climate change on Saturn and its moons.
