A group of scientists from the University of California-Davis has detected the presence of a distant galaxy. The discovery couldn’t be possible without the use of gravitational lensing, a phenomenon first predicted by no less than Albert Einstein himself.
The image of that faintest galaxy was magnified using the gravitational lenses, which according to the official statement from UC Davis is a highly technical and advanced telescope that can magnify incredibly faint objects in the space.
The 10-meter telescope, stationed in W.M. Keck Observatory in Mauna Kea, Hawai, was instrumental in this monumental discovery, published in the science journal of Astrophysical Journal Letters last week.
Marc Kassis, an astronomer at the Kerk Observatory, said that the discovery of the faint galaxy has brought so much excitement to the group, especially since they initially infer the stellar at a low 1 percent.
“It’s a very, very small galaxy and at such a great distance, it’s a clue in answering one of the fundamental questions astronomy is trying to understand: What is causing the hydrogen gas at the very beginning of the universe to go from neutral to ionized about 13 billion years ago? That’s when stars turned on and matter became more complex,” Kassis said in a statement.
According to scientists from UC Davis, the telescope from Kerk Observatory is by far the best instrument of its kind in the world today, since it allows scientists to observe the farthest point in the universe never seen by humans before.
They added that the magnified object was likewise spotted by the Hubble Telescope orbiting in space collecting data and images. But by using a unique technology called the DEIMOS (DEep Imaging and Multi-Object Spectrograph) attached to the Keck II telescope, observers in Kerk Observatory have confirmed that they spotted the same object.
