Giant telescope to survey galaxies from Mexican volcano

Sep 09, 2010 by Sofia Miselem
A worker does his job next to the Large Millimeter Telescope (LMT) on the Sierra Negra volcano, in the Mexican state of Puebla on September 3. Resembling a massive white satellite dish, the LMT will be the largest and most sensitive single-aperture telescope operating at its range.

A giant telescope, 50 meters (164 feet) across, will this year start unraveling mysteries of the birth and death of galaxies up to 14,000 light years away, from atop a Mexican volcano.

Resembling a massive white satellite dish, the Large Millimeter will be the largest and most sensitive single-aperture telescope operating at its range.

It sits at a height of 4,580 meters on the summit of Sierra Negra, an extinct volcano in the central state of Puebla, which lies alongside Mexico's highest mountain, the snowy-peaked Pico de Orizaba.

Built at a cost of 115 million dollars, it is the world's largest telescope operating in millimeter waves (mainly from 0.85 to three millimeters), which allow it to capture radiation from space, the coldest regions of the universe, or planetary formations.

After a 12-year construction process and a test run in 2008, it is due to start research operations at the end of this year.

"We'll make the first observation as part of an investigation," said Raul Mujica, a researcher from the joint project between the University of Massachusetts and the Instituto Nacional de Astrofisica, Optica, y Electronica (INAOE) in Mexico.

Three quarters of the investment is from the INAOE and one quarter from the US university, in a division to be mirrored in the observation time for each team of researchers, said Jose Guichard, director of INAOE.

The researchers admit they are unlikely to achieve concrete results in "earthly terms" in the short term, but that in the future the telescope will help advances in fields from telecommunications to medicine.

"We'll explore theories of the origin of life, like those which lead to the birth of a comet. We'll study comets, their , before they catch fire near the ground," Mujica said.

The telescope will also study the atmospheres of the planets, seeking possibilities of life, said researcher Miguel Chavez.

"As worlds, we're not alone," Chavez said, adding that the telescope could see possible traces of the presence of oceans or plants and identify if there were signs of life.

After receiving its first data, Mexico's massive telescope will be set to progressively observe more distant galaxies.

The observations are due to complement others carried out by telescopes such as an even bigger one under construction by the European Southern Observatory (ESO) in a multinational project in Chile.

Lost something in translation.

This article is a classic... comets on fire near the ground, galaxies a stones throw away being lauded as an epic achievement. Voted 5 stars for comedy value :-)

""As worlds, we're not alone," Chavez said, adding that the telescope could see possible traces of the presence of oceans or plants and identify if there were signs of life."

I'd be interested in more details about these types of observations.

"After receiving its first data, Mexico's massive telescope will be set to progressively observe more distant galaxies."

Seems strange to allocate time on a telescope on the basis of the objects' distance from Earth, if this is what is being implied.

"This article is a classic..."

I guess it (really) might be a language problem.

Yes , very impressive that it can see the birth and death of the Milky Way Galaxy.

Thousands, millions, billions? They all have 3 zeros at the end. Pick one. Of course maybe a light year is longer than a regular earth year after all.

maybe long distance objects need longer exposure times, just like optical telescopes receives less photons per hour from long distance objects?
