Scientists get a peep into early universe

An international team of scientists claimed to have discovered a stardust-filled galaxy dubbed A2744_YD4, which is expected to provide the scientific community with a peep into the formation of the first stars in the universe.

Led by University College London's Nicolas Laporte, the scientists observed the A2744_YD4 galaxy using the European Southern Observatory's Chile-based Atacama Large Millimeter/sub millimeter Array.

Situated nearly 13 billion light-years form Earth, the newly-discovered galaxy is part of Sculptor constellation and is eclipsed by a batch of galaxies called Pandora's Cluster.

Speaking on the topic, Laporte said, "Not only is A2744_YD4 the most distant galaxy yet observed by ALMA, but the detection of so much dust indicates [that] early supernovae must have already polluted this galaxy. Determining the timing of this 'cosmic dawn' is one of the holy grails of modern astronomy."

To astronomers, the new galaxy offers a view of the universe in its infancy, when it was just 600 million years old. That was the period of the formation of early stars and galaxies. Now, the universe is roughly 14 billion years old.
