According to scientists, one out of every five galaxies is obscured by cosmic dust, which has sparked alien aspirations.
Following the finding of two previously unseen galaxies, astronomers are hoping that new technologies may reveal what lies behind the countless galaxies obscured by cosmic dust.
Astronomers now assume that one out of every five galaxies is obscured by cosmic dust, implying that there are considerably more visible galaxies than previously thought.
This also means that, until recently, we have had no idea what – or who – lies beyond the dust.
The discovery comes after radio telescopes in Chile’s Atacama Desert uncovered two previously unseen galaxies, REBELS-12-2 and REBELS-29-2, which were substantially shrouded by dust.
The dust has obscured both from NASA’s Hubble Space Telescope.
According to those who made the discovery, 20% of the universe’s galaxies are concealed in this fashion.
Researchers at the Niels Bohr Institute at the University of Copenhagen, who conducted the latest study published in Nature, are hopeful that new technologies, such as the future James Webb Space Telescope, will aid in the discovery of more of these hidden galaxies.
Pascal Oesch, a Niels Bohr Institute associate professor, said: “We were looking at a sample of very distant galaxies that the Hubble Space Telescope had already discovered.
“Then we realized that two of them had a neighbor who we had not anticipated seeing.
“Due to the dust that surrounds each of these neighboring galaxies, some of their light is obstructed, making them opaque to Hubble.”
The ground-based radio telescopes of the Atacama Large Milimeter Array (ALMA) discovered REBELS-12-2 and REBELS-29-2.
The ALMA, which began observations in 2011, has a spatial resolution five times that of the Hubble Space Telescope, which was launched in 1990.
As a result, there is optimism that more advanced technologies will enable us to see beyond the cosmic dust.
The James Webb Space Telescope is the most recent advancement in space telescope technology, and it is set to launch on December 22 after 25 years of development.
Its primary goal is to improve our understanding of how galaxies develop, but its greater sensitivity will also allow us to discover previously unknown galaxies.
Oesch went on to say: “The next stage is to find the galaxies we missed, as there are a lot more than we imagined.
“The James Webb Telescope will be a big step forward in this area.
“It will be significantly more sensitive than Hubble and capable of probing longer wavelengths, allowing us to easily see these hidden galaxies.”
