Current Context : James Webb Space Telescope spotted earliest-known galaxy called JADES-GS-z14-0.

• It is bright and big considering it formed during the universe’s infancy — at only 2% its current age.
• Discovery of galaxy was made by an international team of astronomers by using JWST to observe galaxies as part of the JWST Advanced Deep Extragalactic Survey (JADES)
• The galaxy has a mass equivalent to 500 million stars the size of our Sun and is rapidly forming new stars — about 20 every year.
• Webb used its huge 5m-wide primary mirror and sensitive infrared instruments to make the discovery.

ABOUT TELESCOPE :

• James Webb Space Telescope (JWST) was launched in 2021 as a joint venture of the US, European and Canadian space agencies.
• Objective : to see farther across the cosmos and further back in time , than any previous astronomical tool.
• JADES-GS-z14-0, Webb can see a significant amount of oxygen, which tells researchers the galaxy is already quite mature.
