'Dead' galaxy from when Universe was 1.65 bn yrs old spotted
Astronomers have spotted the earliest 'dead' galaxy which went inactive when the 14-billion-year-old universe was 1.65 billion years old. They found that within a short period, the galaxy formed all its stars (three times more than Milky Way), but stopped a billion years after Big Bang. This challenges the theory that galaxies started dying three billion years after Big Bang.
