Have you heard about The ‘Invisible Galaxies’?

NASA’s Hubble Space Telescope has been providing scientists with some incredible photographs of the distant universe. Nevertheless, it can’t see the whole thing. 

There are galaxies from the very distant universe that the Hubble “eyes” can’t see. That’s why they are called invisible galaxies.

Therefore, for the Hubble to spot those invisible galaxies, it requires them to use a different set of peepers.

An international collaboration of researchers has used the Atacama Large Millimeter Array (ALMA) in Chile as their eyes to the invisible.

Moreover, it can help them to look back at the early universe and find ancient galaxies that could reveal more about the nature of dark matter and supermassive black holes.

Just recently, research was published in the journal Nature. Surprisingly, they found 39 ancient huge galaxies from around 2 billion years ago after the beginning of the universe which isn’t bright enough to see it.

The Invisible Galaxies are now Visible

With the help of ALMA and NASA’s Spitzer space telescope, the research team was able to confirm the existence of the invisible galaxies they suspected that were hiding out at the farthest edges of the cosmos.

“The light from the galaxies we discovered is very weak with long wavelengths undistinguishable to our eyes and undetectable by Hubble,”

explained Kotaro Kohno, a co-author on the paper and scientist at the University of Tokyo, in a press release.

On top of that, they are incredibly dusty, huge galaxies, which conceals them from Hubble’s view. 

The researchers can’t confirm exactly how old these galaxies are or what makes them up. But it has changed the current understanding of galaxy evolution.

The amount of massive, dust-filled galaxies detected surpasses what we have expected with our current models of the universe.

Thus, challenging the current hypotheses of how these massive galaxies evolve.

Their discovery also opens the opportunity of studying other galactic wonders such as supermassive black holes which scientists know exist in the center of big galaxies.

They want to study the mysterious dark matter which is theorized to make up most of the matter in our universe.

The James Webb Telescope is NASA’s next-gen telescope to study the universe. They are planning to launch it in 2021 and it may be the key to further understand the invisible galaxies spotted.
