Interesting and important is not only the discovery of water itself, but also where it occurred. This double galaxy is remarkable for several reasons. “It is the most massively known galaxy with a high redshift; that is, it dates back to a time when the universe was very young, ”Jarugula described.
But it is fundamentally different from other similar galaxies of the same period: it has more gas and dust compared to them, “which gives us plenty of potential opportunities to observe the most common molecules and better understand how these life-forming elements affected the evolution of the early universe,” she added. scientist.
Let there be water
Although there is currently a shortage of water on Earth in many places, in fact, water is the third most common molecule in the universe. The first is molecular hydrogen (ie two hydrogen atoms) and the second is carbon monoxide. The more complex molecules known as “dust” are heated by ultraviolet light and then radiate in the infrared part of the electromagnetic spectrum. Astronomers have found that there is a link between water and dust emissions.

The light from the galaxy SPT0311-58 comes from a period of space that science still does not fully understand. This discovery suggests that water was an important player from the very beginning of its existence. Its role is still unknown, but the very information about its existence at the dawn of space is an important piece of the puzzle that can help scientists understand what was happening in the early universe.
