Astronomers Find Two New Galaxies ‘Hiding’ Behind Curtain of Dust

Despite the amount of time it took for the light from these galaxies to reach Earth, they are still far away from the universe’s current size. For them, the universe is constantly expanding.
A study published in the journal Nature revealed that galaxies that were in the early universe may have been hiding in the dust clouds. The researchers estimated that about 10 to 20 percent of the universe’s galaxies are hiding.
Using the ALMA telescope, astronomers were able to study the universe’s mysterious objects using Hubble’s telescope. They were able to observe objects in the visible and ultraviolet wavelengths of light.
According to researcher Pascal Oesch, they were studying a group of galaxies using the ALMA telescope when they discovered that two of them had a neighbor that wasn’t expected to be there.
In his New Atlas article, Oesch explained how scientists are trying to answer the big puzzle of the universe’s formation.
In order to get the most out of their work, astronomers are waiting for the launch of powerful instruments such as the James Webb Space Telescope.
Oesch said that they were able to see the strange neighbor through the ALMA images.
They usually use the telescope to study the universe’s mysterious objects. This time, they used the ALMA telescope to study the cosmic objects using the Hubble Space Telescope.
The discovery suggests that many of the early universe’s galaxies may be hiding behind dust clouds.
According to Oesch, they were studying a group of galaxies using the ALMA telescope when they noticed that two of the them had a neighbor.
In order to get the most out of their work, the astronomers are waiting for the launch of new instruments such as the James Webb Space Telescope. This telescope, which is scheduled to launch in December, will be used to study infrared images of the universe.
Despite the distance between Earth and the galaxies, the light from them still reaches us 13 billion years later. In total, the universe is 29 billion light-years away.
