The Second-Oldest and Most Distant Celestial Objects Discovered By Large Millimeter Telescope

Astronomers have recently confirmed the detection of second most distant and oldest galaxy ever in the cosmos, which is estimated to be about 12.8 billion-years old. it is a star-making galaxy and named as ‘G09 83808’.

Detection of the galaxy has been made with the international team of scientists from the National Institute of Astrophysics, Optics and Electronics of Mexico and University of Massachusetts Amherst. The team used a new muscular telescope known as Large Millimeter Telescope (LMT) located at Volcán Sierra Negra in Galapagos.

However, the galaxy was first observed with the Herschel space telescope. But, that became very problematic due to its low resolution of pictures and collected data was also rated as unreliable to be considered for the foolproof calculations.

The distance of this most ancient galaxy has been measured with the help of expansion speed of the cosmos as a scale. Then the Large Millimeter Telescope began its detections in 2011, which has a 50-meter diameter dish and started the process of collecting light.

Min Yun, an astrophysicist at the University of Massachusetts Amherst, stated that, “The Big Bang happened 13.7 billion years ago and now we are seeing this galaxy from 12.8 billion years ago, so it was forming within the first billion years after the Big Bang. Seeing an object within the first billion years is remarkable because the universe was fully ionized, that is, it was too hot and too uniform to form anything for the first 400 million years.”
