Two of our galaxy's most massive stars, until recently shrouded in mystery, have been viewed by the Hubble Space Telescope, unveiling greater detail than ever before.
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. The Carina Nebula
contains several ultra-hot stars, including these two star systems and the famous blue star Eta Carinae
, which has the highest luminosity yet confirmed.
