Our Galaxy’s Supermassive Black Hole May Have Had a Companion in the Past
Could there have been two massive black holes in our galaxy’s center at one time? New modeling of fast-moving stars in the Milky Way’s halo suggests the answer is yes.

Researchers have detected water vapor around a B[e] supergiant star for the first time, indicating a likely binary companion for LHA 115-S 18.
Enhancing the Sharpest Images
Event Horizon Telescope images are already some of the sharpest in all of astronomy. A new algorithm might be able to squeeze even more information out of them with complex statistical modeling.
