Galaxy suspected to lack black hole
Astronomers have opened a new case file: the Mystery of the Missing Black Hole.
Until now, scientists had spotted supermassive black holes at the centers of all galaxies studied in detail. But a team from Rutgers University found a galaxy with either a tiny black hole or none at all.
The astronomers used the Hubble Space Telescope to scrutinize the nearby galaxy M33, long suspected to lack a black hole. The new observations show that certain stars orbit the galaxy's center more slowly than they would if a massive black hole were dragging them around.
If M33 does contain a black hole, it must be less than 3,000 times the sun's mass, the researchers report in the online version of the journal Science. By comparison, the Milky Way galaxy harbors a black hole about 3 million times the sun's mass.
