During this time we have looked at the Milky Way galaxy and are in awe of everything that exists. But all that we see is what the human eye can see, which is related to the reflection of light.
This situation changes when a technology is able to display amazing colors that are different from usual. The reason is, the Murchison Widefield Array Telescope, located in the interior of Western Australia, translates radio waves in the universe into visual forms.
Unlike the human eye, which sees the universe by comparing the brightness in three primary colors: red, green and blue.

With this superhuman ability, we will be able to see the galaxy we live in in 20 primary colors.
"This is much better than human ability in general. It even beats animals, like the mantis shrimp, which can see 12 different primary colors, ”explained astronomer Natasha Hurley-Walker of Australia's Curtin University.
The $ 50,000,000 radio telescope carried out an unprecedented space survey a few years ago. The project is known as the GaLactic and Extragalactic All-sky survey (GLEAM).
This GLEAM view of the Milky Way reveals the galactic center is bright red — indicating the lowest radio frequency — with the center and highest frequencies represented by green and blue.
Every point in the image is another galaxy. To date, the survey has cataloged more than 300,000 of them. This means that some of the radio waves seen in this image have actually been traveling through space for billions of years.

"Our team uses this survey to find out what happens when galaxy clusters collide," said Hurley Walker. "We can also look at the remains of explosions from the most ancient stars in our galaxy, and find the first and last breaths of various supermassive black holes."
The Murchison Widefield Array telescope is just a warm-up before the next big step created in radio astronomy, the Square Kilometer Array telescope, also built in Australia. The largest telescope of its kind would be able to detect the weakest radio signal emitted more than 13 billion years ago, when the earliest stars and galaxies began to form.
