Ջեյմս Ուեբ տիեզերական աստղադիտակ (JWST)Է, տարածություն observatory designed to conduct infrared astronomy and launched successfully on 25 December 2021 will enable two research teams to study earliest galaxies in the տիեզերք. The research teams will use JWST’s powerful instruments (NIRISS, NIRCam and NIRSpec) to capture and characterize some of the earliest galaxies.
The Next Generation Deep Extragalactic Exploratory Public (NGDEEP) Survey will target Hubble Ultra Deep Field by pointing telescope’s Near-Infrared Imager and Slitless Spectrograph (NIRISS) on the primary Hubble Ultra Deep Field and Near-Infrared Camera (NIRCam) on the parallel field. The two instruments NIRISS and NIRCam will capture infrared light (redshifted due to expansion of տիեզերք). The data will be released immediately to benefit the researchers.
NGDEEP team will also identify metal elements in the early galaxies especially in smaller and dimmer ones that haven’t yet been thoroughly studied so far. Study of metal contents of galaxies is standard way to trace evolution across cosmic time. There were only hydrogen and helium in the beginning of the տիեզերք. New elements were formed by successive generations of աստղերը. Studying metal contents of galaxies will help to plot out precisely when various elements existed and update models that project how galaxies evolved in the early տիեզերք.
The other research team will examine the primary Hubble Ultra Deep Field using the microshutter array within the telescope’s Near-Infrared Spectrograph (NIRSpec). This will provide first large sample of earliest galaxies that existed in the early տիեզերք enabling researchers to understand them in detail.
The story of study of վաղ տիեզերք began in 1995 with the decision to focus Hubble Տարածություն Telescope (HST) on nothing in the hitherto unexplored field in the sky. Hubble captured about 3000 images of galaxies at different stages of stellar evolution. Better known as Hubble Deep Field, these images were first pictures of early galaxies and revolutionised the field of astronomy.
As a successor of Hubble տարածություն telescope (HST), Ջեյմս Ուեբ տիեզերական աստղադիտակ (JWST) is carrying forward the Hubble աստղադիտակի ժառանգությունը վաղ ուսումնասիրության ոլորտում տիեզերք. Webb telescope aims to search for light from the first աստղերը and galaxies that formed in the Տիեզերք after the Big Bang to study the formation and evolution of galaxies, to understand the formation of աստղերը և մոլորակային systems and to study մոլորակային systems and the origins of life.
Վաղը տիեզերք in the first several hundred million years after the big bang was a very different place. It was semi-opaque. This is when the first galaxies in the տիեզերք were beginning to form. Many distant galaxies have been spotted by the telescopes but none earlier than 400 million years after the big bang. What were galaxies that existed even earlier like? The above mentioned, two research teams will answer just this by revealing details of the earliest chapters of Հարդագողի ճանապարհ էվոլյուցիան:
