An Italian-led study published on
Nature has discovered the oldest black hole ever seen, some 13
billion years old.
The discovery, led by Cambridge University researcher Roberto
Maiolino, was made thanks to the James Webb Space Telescope of
NASA, the European Space Agency and the Canadian Space Agency.
The black hole dates back to just 400 million years after the
Big Bang.
The international team, which included other Italians and saw
the contribution of Pisa's prestigious Scuola Normale, showed
that the object is surprisingly large for the primordial
universe, a few million times the size of our Sun, a discovery
which calls into question current theories of how black holes
are formed.
