"NASA's Hubble Space Telescope has found a rare class of oddball stars called blue stragglers in the hub of our Milky Way,
the first detected within our galaxy's bulge.
The findings support the idea that the Milky Way's central bulge stopped making stars billions of years ago. It now is home to aging sun-like stars and cooler red dwarfs. Giant blue stars that once lived there have long since exploded as supernovae. "
What does that mean - in the bulge - away from the galactic centre?
I ask because apparently at least one young blue star has been detected before (Andrea Ghez 2003). One designated SO-2 has a tight orbit of around 130 - 1900 AU from the object at our galactic core (that's in the bulge - isn't it?) for which there is considerable evidence is where a black-hole resides.
