A monster star thought to be among the most massive in
our Milky Way galaxy is actually slimmer than expected
because it’s actually a pair of twins, astronomers
Researchers once believed the star known as Pismis 24-1
loomed large with a mass between 200 and 300 times that
of the Sun.
But more accurate measurements by the Hubble Space
Telescope found not one, but two stars in Pismis 24-1’s
location, effectively cutting the estimated weight in half to
about 100 solar masses.
Pismis 24-1 sits in star cluster at the core of the emission
nebula NGC 6357 some 8,000 light-years from Earth
towards the constellation Sagittarius.
It’s possible that Pismis 24-1 may include a third star
based on some ground observations, Hubble researchers
If true, each of the three stars would average about 70
stellar masses, but remain on the Top 25 roster of the
Milky Way’s most massive stars.
