Astronomers may have discovered the signature of one of the Universe’s earliest stars.
Theoretical models predict that some of the very first stars were hundreds of times larger than the Sun.
But no clear evidence of this had been found so far.
Scientists writing in the journal Science have discovered the traces of an early massive stellar object in the exceptional chemical composition of a star in our galaxy.
“This is quite a unique star, with a very peculiar chemical pattern that has never been found previously,” said lead author Dr Wako Aoki, from the National Observatory of Japan.
