NASA's James Webb Telescope Discovers Most Distant Galaxy

TapTechNews May 31. Since the James Webb Space Telescope of NASA in the US has been put into use, it has reaped many ground-breaking observational results. According to the blog of NASA on May 30, the telescope has just discovered the most distant known galaxy ever.

The article says that this JADES-GS-z14-0 galaxy was formed only 290 million years after the Big Bang. This galaxy is very large, with a diameter of 1600 light years. Considering that it was formed shortly after the Big Bang, it is also very bright and has an unusually large number of starlight.

Researchers Stefano Carniani and Kevin Hainline questioned, How could nature create such a bright and large galaxy in less than 300 million years? On the cosmic time scale, this is just a flash in the pan.

The MIRI (Note by TapTechNews: Mid-infrared Instrument) of the Webb Space Telescope found that the light wavelength emitted by JADES-GS-z14-0 indicates the existence of strong ionized gas emissions, which may come from abundant hydrogen and oxygen. This is also very strange because usually there is no oxygen in early galaxies. This indicates that before we observe the Milky Way, multiple generations of very massive stars have already existed.

NASA said that this discovery means that the galaxy has produced multiple generations of massive stars in less than 290 million years. Stars only take about 10 million years to form, but it may take up to 20 billion years to die. However, the lifespan of supermassive stars is usually shortened, so this discovery does not completely rewrite our understanding of the universe, but it does raise questions about the nature of early stellar formation in the universe.
