ANSWER: 400
Explanation:
Through the combined power of Hubble and Spitzer space telescopes, scientists have unearthed the faintest object seen in the universe which existed 400 million years following the big Ban 13.8 billion years ago. The object has been named Tayna which stands for "first-born" in Aymara, a language spoken in the Andes and Altiplano regions of South America. This object represents a fainter class of newly forming galaxies which had escaped detection till now. The remote object is part of a discovery of 22 young galaxies at ancient times located nearly at the observable horizon of the universe.
