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.
