The Iris Nebula is a bright reflection nebula in the constellation Cepheus, 1,300 light years away from Earth. The nebula contains at its centre an extremely young star named V380 Cep which is believed to have burst into life just 5,500 years ago. Since still incredibly young there is plenty of local dust surrounding the star and when starlight hits the dust it's reflected to become the visible nebula.
