This new Hubble image, captured and released to celebrate the telescope's 23rd year in orbit, shows part of the sky in the constellation of Orion (The Hunter). Rising like a giant seahorse from turbulent waves of dust and gas is the Horsehead Nebula, otherwise known as Barnard 33.
The image shows a pair of colossal stars, WR 25 and Tr16-244, located within the open cluster Trumpler 16.This cluster is embedded within the Carina Nebula, an immense cauldron of gas and dust that lies approximately 7500 light-years from Earth in the constellation of Carina, the Keel.
