- James Webb Space Telescope, the world's most powerful telescope, has discovered the oldest galaxy in the universe.
- It has spotted galaxy candidates that existed when the universe was just 300 million years old, an infant stage in cosmic terms.
- It spotted two candidates to be the oldest galaxies in the universe GLASS-z11 and GLASS-z13.
- GNz11 remains the only galaxy to have been confirmed to exist in the first few hundred million years after the Big Bang, the moment when our universe came to life.
- The light from GLASS-z13 has taken about 13.4 billion years to hit the mirrors of the spacecraft.
- This is located nearly 15,00,000 kilometres away from Earth.
