Sugar Molecules detected around Young Star (ESO)

The sugar molecules are not only found in the right place but are on the right track towards a planet

An international team of astronomers has detected for the first time sugar around a young star, said the European Southern Observatory (ESO) from its headquarters in the town of Garching, in southern Germany.

With ALMA radio telescope, located in the Atacama Desert, Chile, on the Chajnantor plateau at 5000 meters high, the scientists were able to capture glycol aldehyde molecules in the gas surrounding the young binary star IRAS 16293-2422, with a mass similar to the Sun and located 400 light years from Earth.

“In the disk of gas and dust surrounding the star forming glycol aldehyde recent find, a simple sugar that is not very different from what we put in coffee,” said Jes Jørgensen, Niels Bohr Institute in Denmark and lead author of the study.

According to the astronomer, “this molecule is one of the ingredients in the formation of ribonucleic acid (RNA), which like the DNA, which is related, is one of the key ingredients for life.”

“What’s really fascinating is that our findings with ALMA observations reveal that the sugar molecules are falling toward a system of stars,” said Cécile Favre, University of Aarhus (Denmark).

Moreover, “the sugar molecules are not only found in the place to find their way to a planet, but also going in the right direction,” he added.

Thus, this finding demonstrates that the essential elements for life are in the right time and place to exist on planets that form around the star.

Glycol aldehyde already been spotted in interstellar space before, but this is the first time that it is located so close to a star of this type, a distance equivalent to separating the Sun Uranus in our own solar system.

“It raises a big question: How complex can become these molecules before they are incorporated into new planets? This could give us an idea about how life could arise elsewhere,” said Jorgensen.

According to the scientist, the observations with the Large Millimeter/sub millimeter Array Atacama (ALMA), characterized by high accuracy and sensitivity, “will be vital to unravel this mystery.”

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.
