  • NASA Hubble & Spitzer telescopes spot Faintest Galaxy!

Astronomers believe the faintest object named ‘Tayna’ is an early galaxy which existed 13.8 billion years ago.

The telescopes at NASA have found a galaxy they believe was part of the Early Universe. The faint object was found by the telescopes Hubble and Spitzer. The object is being called the Faintest Galaxy.

The object was also recently nicknamed as Tayna which means first born in Aymara. Aymara is a language spoken in the Andes and Altiplano regions of South America. Astronomers believe the Tayna could be a galaxy which existed 13.8 billion years ago.

Some speculate the object could have been a galaxy 400 million years after the big bang. A majority of astronomers agree the galaxy could be part of an early universe. 

Tayna is similar in size to the Large Magellanic Cloud (LMC). LMC is a diminutive satellite galaxy of our Milky Way. Researchers believe Tayna will likely evolve into a full-sized galaxy. The galaxy Tayna was spotted through the Hubble Frontier Fields program.

The galaxy is about roughly 4 billion light-years away from our galaxy. Hubble and Spitzer used a color profile technique to determine the distance of Tayna. The infrared waves of the galaxy were measured to determine the distance by the telescope.

Studying Tayna could offer clues into the formation and evolution of the first galaxies. The finding also suggests the early universe could be rich in galaxies. The galaxies could be targeted by the upcoming James Webb Space Telescope for further study. The findings were published in The Astrophysical Journal on Thursday. 

An astronomer Leopoldo Infante is the lead author of the paper detailing the findings. Infante is also a researcher at the Pontifical Catholic University of Chile. 

"Thanks to this detection, the team has been able to study for the first time the properties of extremely faint objects formed not long after the big bang," said lInfante.
