Astronomers using the James Webb Space Telescope identified COSMOS-74706, a barred spiral galaxy dating back 11.5 billion years, as a strong candidate for one of the universe's earliest galaxies with a stellar bar structure. The discovery, confirmed through spectroscopy by University of Pittsburgh researchers, suggests such structures formed approximately 2 billion years after the Big Bang, earlier than previously expected.
