Say hello to the Carina Nebula 👋 

One of the largest panoramic images ever taken with our Hubble Space Telescope’s cameras, this image features a stunning 50-light-year-wide view of the intense central region of the Carina Nebula — a strange stellar nursery. The nebula is sculpted by the action of outflowing winds and scorching ultraviolet radiation from the monster stars that inhabit this inferno. The Carina Nebula lies within our own galaxy, about 7,500 light-years away. 

At the heart of the nebula is Eta Carinae — a system of two stars. The larger star, Eta Car A, is around 100 times as massive as the Sun and 5 million times as luminous! Stars of this size are extremely rare; our galaxy is home to hundreds of billions of stars, but only tens of them are as massive as Eta Car A.

This view of the Carina Nebula provided astronomers the opportunity to explore the process of star birth at a new level of detail. The hurricane-strength blast of stellar winds and blistering ultraviolet radiation within the cavity are now compressing the surrounding walls of cold hydrogen. This is triggering a second stage of new star formation. Hubble has also enabled scientists to generate 3-D models that reveal never-before-seen features of the interactions between the Eta Carinae star system.
