Within the constellation Cygnus, an elderly star and its massive companion are having one last hurrah, flinging off mass at an incredible rate before they explode as supernovae and collapse into a black hole.
Now, researchers including recent Embry-Riddle Aeronautical University graduate Laura M. Lee have mapped the elderly star s orbit around its oversized and equally ancient partner. In a scientific first, they have also determined the dynamical mass of both stars that make up a binary system called Wolf-Rayet 133. ....

BitFlow Reaches for the Stars Helping Mount Wilson Observatory Capture Celestial Images
Written by AZoOpticsJan 11 2021
Located on Mount Wilson, California, Georgia State University s Center for High Angular Resolution Astronomy array (CHARA) is the world s largest optical interferometer and has delivered landmark sub-milliarcsecond results in the areas of stellar imaging, binaries, and stellar diameters. CHARA is comprised of six separate telescopes across Mount Wilson that act together as one enormous telescope to attain the resolving power to define amazingly small details. To operate, the light obtained from each telescope is combined and a final reconstructed image can be observed that is of far higher resolution than would otherwise be possible. ....
