Astronomers Have Detected a Galaxy Millions of Years Older Than Any Previously Observed

With the help of by James Webb Space TelescopeThe group of astronomers broke the oldest, farthest record to the galaxy found by people to date.

In a preprint studyAstronomers waiting for a peer review and publication in a magazine, describe this primitive galaxy, named after the mother Z14. According to researchers, this “space miracle” was 280 million years after a large explosion 280 million years later, Jades-GS-Z14-0 created a galaxy 290 million years after the origin of the universe.

To put these measurements in the context, the current age of the universe is estimated to be 13.8 billion years. The Earth is an estimated 4.543 billion year old. No one expect the James Webb space telescope to be the potential to observe the things that the great thing from the big explosion.

A short reminder about distances relative to space time. Because it is light at a speed of 300,000 meters per second and space is expanded, and because of the expanding of space, it is equal to how many years ago are the light of many distant objects. For example, when we say that mother Z14 is about 13.5 billion years old, it means that you have to travel to the speed of light to reach the target for 13.5 billion years. So far, it is clearer than a scientific instrument and at the same time, there is nothing older and older.

James Webb Space Telescope allows you to learn some aspects of the universe in the early stages, with deep look at a deep space. How does it make it? By infra-red sensors. Almost all the galaxies we see from the ground due to the expansion of the universe. Thus, from the point of view, the longer their light seems to have a longer wavelength, because it stretches with this action. We call this “redshift“: Their wavelengths are Ridder because they are longer, and this is a previous object created, and therefore redshift is more than a long time.

James Webb Space Telescope was able to determine that the mother was 50 times smaller than Z14 Milkyaloli, and also revealed the existence of nitrogen and carbon in the galaxy. Although this is a total of 280 million years older than this galaxies, the stars in these galaxies are not only the first generation of these galaxies, for the early universe. The heavier elements came only afterAfter production in the stars.

Can James Webb pass this limit and find the first generation galaxies? Such discoveries may have a long way, but we have to continue to look.
