This vast universe contains huge numbers of dwarf and giant galaxies, and perhaps the most famous of these galaxies is the Milky Way, to which our solar system belongs.
Space science has developed over time, and space flights and satellites have been sent by specialized astronomers into space, to determine the farthest object that can be observed from Earth in this vast universe.
It’s hard to imagine the size of the universe from the usual human point of view, each of the galaxies contains billions of discovered and undiscovered planets, both larger than Earth and even smaller.
This universe contains more than 17,000 million galaxies within the limited space that has been discovered from the universe only!
The famous NASA astronomers, as well as other astronomers around the world, continue to conduct research, flights, and send space shuttles and satellites, in order to identify and learn more and more regarding this vast universe.
Although the discovery of a new body within the universe is considered as a drop in the sea of this universe. However, each new discovery gives the world new information to determine the characteristics of the mysterious space.
What is the farthest galaxy discovered in the universe so far?
HD1 is the most distant galaxy discovered in the universe
This year, a group of astronomers at Harvard and Tokyo universities discovered the presence of a red body 13,500 million light-years from Earth.
Thus, astronomers considered this object to be the most distant galaxy that has been discovered so far in this universe.
A famous astronomer named Yuichi Harikan explained that the process that aimed to identify this galaxy, which took the form of a red glowing body, was a very difficult process, as more than 700,000 objects were monitored, to identify an element that was seen in the form of a very bright and glowing red body as well.
HD1 was the name given to the discovered galaxy, which is considered to be the farthest galaxy in the universe.
The search to locate the farthest galaxy took more than 1,200 continuous hours through the Subaru, Vesta, Spitzer telescope, and another British telescope.
The HD1 galaxy, which appeared in the form of a red glowing body, was able to extract the title of the most distant glowing object observed in the universe from the GN-z11 galaxy, which was a hundred million light-years away from the Earth from the HD1 galaxy.
Astronomers around the world have been surprised by the activity of the HD1 galaxy and its intense ultraviolet radiation.
This was explained by two hypotheses. The first is that the galaxy discovered in the form of a distant red glowing body can produce more than 100 stars annually! This is the reason for the emission of radiation.
Or that there is a massive black hole in the galaxy HD1 that emits ultraviolet radiation.
The HD1 galaxy, which appeared to be visible in the form of a red glowing body, continues by astronomers, with an advanced telescope that can monitor the farthest point discovered so far in this universe.
How did scientists determine the age of the farthest galaxy discovered in the universe?
Specialized astronomers constantly do a lot of research to determine the ages of galaxies in general, and are particularly interested in the ages of the distant galaxies to determine more information regarding these discovered galaxies, by means of the so-called redshift.
It is the increase in wavelengths of light towards the red color range of the spectrum that is received by searchlights when compared to the light from the source.
Because space is constantly expanding, the farther a galaxy moves from the observer, the longer the wavelength increases, toward a clear red color of the spectrum.
The HD1 galaxy, which appeared in the form of a red glowing body, was determined to have formed only 330 million years following the Big Bang.
Which made it the farthest galaxy discovered in the universe.
What is the Big Bang?
Until now, specialized astronomers relied on the Big Bang theory to determine the age of every object and galaxy in the universe as a zero principle for the formation of the universe.
As mentioned above, the HD1 galaxy, which appeared in the form of a red glowing body, was considered the most distant galaxy discovered in the universe due to its proximity to the principle of time, which is the Big Bang.
The Big Bang is a theory that says that the universe in which we live was made up of one coherent substance, and then that matter was exposed to the Big Bang or the Big Bang, which made that matter diverge from each other and spread in the orbit of the universe.
The Big Bang has been estimated to have occurred 13,800 million light years ago.
The Big Bang hypothesis dates back to 1927.
But the name Big Bang was used for the first time, as a joke, in a radio interview for a physicist named Fred Hoyle, with the intent of drawing attention to the idea of the Big Bang.
There is an endless debate between astronomers who support the Big Bang theory and advocates of an opposite theory called the steady state.
HD1 was considered the most distant galaxy discovered, because the time separating it from the Big Bang is only 330 million light-years.
What is a black hole?
It is a region of strong gravity that no object can escape its gravity, even light, and thus takes on the color black.
Specialized astronomers believe that nearly every galaxy should contain one or more black holes.
And the astronomers’ body continues to work continuously to identify more new elements to be added to the list of discovered objects in the universe.
The element was discovered in the form of a red glowing body, which was called the object, located at a distance of 13,000 million light years from Earth.
The object, which appears as a glowing red body surrounded by dense cosmic dust, is believed to be one of the progenitors of black holes. It can be considered a star-forming galaxy surrounded by dust and also appears as a black hole at the same time.
The puzzling object, which combines several properties and appears red in color, has been named quasars.
The phenomenon of the collision of two black holes, which is one of the most important recently discovered phenomena, is the second largest cosmic event in terms of importance following the Big Bang. Reflecting the importance of monitoring black holes by astronomers.
Using the James Webb Telescope to demystify the most distant galaxy discovered in the universe
The discovery of the most distant galaxy in the universe constituted a pivotal event for astronomers in general.
Scientist Yuichi Harikanh was very moved by his discovery of the HD1 galaxy, which appeared in the form of a red glowing body, saying: “I got goosebumps when I spotted the red body.”
Astronomers were not satisfied with what the four telescopes provided regarding the galaxy that was considered the most distant galaxy discovered in the universe, the HD1 galaxy.
Rather, the James Webb Telescope was relied upon, which is considered the most accurate telescope capable of capturing the most accurate and remotest images of the elements of the universe.
What are the most famous galaxies in the universe?
There are many galaxies that have been discovered by astronomers in the universe, including:
- The Milky Way: It is the most famous galaxy to which our solar system belongs, with a diameter of 185,000 light-years, and our solar system is regarding 27 thousand light-years away from the center of this galaxy.
- Sombrero: It is a galaxy with a luminous core, located 29 million light years from Earth.
- The Black Eye: It is a beautiful galaxy that takes the form of a beautiful eye with a glowing color close to red, and it is located at a distance of 24 million light years from planet Earth.
- Vortex: It is a beautiful galaxy that takes the form of a vortex, and is away from planet Earth, a distance of up to 23 million light-years.
- NGC-3370: It is a beautiful galaxy located 98 million light-years away from Earth.
- NGC-1512: a ring-shaped galaxy consisting of two glowing rings, 38 million light-years away from Earth.
- 2MASX J00482185-2507365 OCCULTING PAIR: It is two overlapping spiral galaxies, regarding 800 million light-years away from the Milky Way.
- Andromeda: It is considered one of the nearby galaxies that can be seen with the naked eye, more than 2 million light years from Earth, and its diameter is regarding 220 thousand light years.
- Canis Major: It is the closest galaxy to the Milky Way, only 42,000 light-years away!
It should be noted that the unit of measurement of distance in space, which is called a light year, means the distance that light travels within a period of one year.
Announcing the name of the farthest galaxy discovered in the universe has had a fuel-like effect for scientists to continue conducting their research and studies.
This news also had a great impact on the ordinary viewer who is curious to know the hidden side of the universe.
Despite the successive discoveries made in astronomy, these discoveries have been questioned over time, due to the difficulty of verifying what is being announced for the ordinary viewer.
From the discovery of the farthest galaxy to the nearest galaxy, and from a black hole to different and strange planets and stars, space sciences remain the most attractive and mysterious sciences to this day!
