The James Webb Space Telescope, launched by NASA in December 2021, is taking astronomical images of Jupiter’s aurora, deep space objects, and galaxies one following another. A new image of the Tarantula Nebula (30 Doradus) taken by the James Webb Space Telescope has been released, drawing attention as a clue to the mystery 2 to 3 billion years following the Big Bang.
About 160,000 light-years from Earth, the Tarantula Nebula has a complex internal structure. The Tarantula Nebula is a bright object and is the largest and most active star forming region in the local group of the Milky Way Galaxy.
NASA released a clear image of the Tarantula Nebula taken by the James Webb Space Telescope on September 6, 2022. Images taken with the NIRCam, a near-infrared camera mounted on the James Webb Space Telescope, show a large number of stars that might not be confirmed by conventional observation instruments. It has also been confirmed that young star clusters exist at the center of the Tarantula Nebula and that they are influenced by the stellar winds they radiate. In addition, NIRSpec analysis of near-infrared spectroscopy revealed that the formation of protostars was included in the pillars growing from the dense peripheral region toward the center.
The longer infrared wavelengths captured by MIRI, a mid-infrared observatory, show a different view of the Tarantula Nebula than the one photographed by NIRCam, as the hot, hot stars are obscured and cold gas and dust are clearly visible.
One of the reasons this nebula is of interest to astronomers is that it has a chemical composition similar to that of a celestial body at a time called the cosmic noon. Cosmic noon refers to the period of rapid growth of galaxies 2 to 3 billion years following the Big Bang, and the huge star formation area during this time has a different chemical composition from the Milky Way Galaxy, where Earth exists.
However, the Tarantula Nebula is only regarding 160,000 light-years from Earth and has a chemical composition similar to that of the cosmic noon star formation region. Therefore, analysis of the Tarantula Nebula is expected to provide important clues to what is happening at noon in space. In an official statement, NASA said humans have been observing stars for thousands of years, but the process of star formation remains a mystery because it has not been able to get clear images of what is happening. The James Webb Space Telescope has already begun revealing aspects of the universe that have never been seen before, he added, adding that this is only the first step in rewriting the story of the birth of stars.
