ESA’s Herschel telescope has snapped an embryonic star likely to turn into one of the biggest and brightest in our galaxy within the next few hundred thousand years.

“This star can only grow bigger,” says Annie Zavagno of the Laboratoire d’Astrophysique de Marseille. But, she says, “According to our current understanding, you should not be able to form stars larger than eight solar masses.”
This is because the fierce light emitted by such large stars should blast away their birth clouds.
