Young Suns of NGC 7129
16.10.2025

Young suns still lie within dusty NGC 7129, some 3,000 light-years away toward the royal constellation Cepheus. While these stars are at a relatively tender age, only a few million years old, it is likely that our own Sun formed in a similar stellar nursery around five billion years ago.

The Lagoon Nebula in Stars Dust and Gas
