Africa-Press – Rwanda. <\/strong><\/span>The new images come courtesy of the James Webb Space Telescope (JWST), the most powerful telescope ever launched. Its sensitivity enables the detection of light billions of years old emanating from sources hundreds of millions of light-years away.<\/p>\n

Far beyond the reach of Sputnik and other man-made satellites, light emitted by some of the oldest galaxies is providing new clues about the fundamental nature of the universe.<\/p>\n

Perhaps one of the biggest surprises offered by the Webb telescope so far relates to some of the oldest known galaxies: the JWST has not only detected the formation of galaxies significantly earlier than previously speculated \u2013 just 200-500 million years after the Big Bang – it\u2019s also observed that those galaxies are much bigger and brighter than was thought possible.<\/p>\n

Scientists expected light from these early galaxies to demonstrate solar systems in an early stage of development \u2013 too young to have yet taken on a characteristic spiral or elliptical shape. But the images instead suggest galaxies with markers of considerable development, such as spiral arms.<\/p>\n

The discovery has spurred one researcher to speculate that the universe is twice as old as previously thought.<\/p>\n

The argument was put forward earlier this year in the journal Monthly Notices of the Royal Astronomical Society.<\/p>\n

However, most scientists caution against such a dramatic rethinking of our understanding without more information.<\/p>\n

Astrophysicists so far have been unable to directly observe any galaxy or star older than 13.8 billion years. Confirmation of an older universe will require further evidence of celestial bodies formed a long time ago in galaxies far, far away.<\/p>\n
