Astronomers continue to ask themselves how you can build a galaxy. They are formulating all kinds of theories about how the gargantuan systems that are filled with gas, dust, and stars can come together.
They are using their telescopes to look at the skies and search for distant galaxies that could help reveal the mystery.
In a new study that’s been published in the journal Nature this week, an international team of astronomers managed to detect light from an ancient, huge galactic disk that’s lurking in a far corner of the universe.
The disk was formed in the earliest days of the universe
It’s been also revealed that the light took about 12.5 billion years to reach out planet – this means that the disk has been formed about 1.5 billion years after the Big Bang. In other words, these were the earliest days of the Universe.
The experts used one of the most powerful telescopes in the world, the Atacama Large Millimeter/submillimetre Array.
With this monster’s help, the team found the galaxy when it was studying bright light from a distant, mammoth black hole – a quasar.
Some of the light has been absorbed by the galaxy on its way to our planet, and this way, it was revealed that it was hiding in the depths of the space.
According to the latest data coming from CNET, the team of experts was able to more clearly resolve some of its features.
“Previous studies hinted at the existence of these early rotating gas-rich disk galaxies,” said Marcel Neeleman, an astronomer at the Max Planck Institute for Astronomy and lead author on the study.
He continued and explained that “Thanks to ALMA, we now have unambiguous evidence they occur as early as 1.5 billion years after the Big Bang.”
It’s been also reported that experts dubbed the galaxy DLA0817g aka the Wolfe Disk – they called it like that in honor of astronomer Arthur M. Wolfe.
