Fun Fact of the Day

Fun Fact of the Day: Black holes come in a range of sizes.
 
There are at least three types of black holes, NASA says, ranging from relative squeakers to those that dominate a galaxy’s center.
 
Primordial black holes are the smallest kinds, and range in size from one atom’s size to a mountain’s mass.
 
Stellar black holes, the most common type, are up to 20 times more massive than our own Sun and are likely sprinkled in the dozens within the Milky Way.
 
And then there are the gargantuan ones in the centers of galaxies, called “supermassive black holes.” They’re each more than one million times more massive than the Sun.
 
How these beasts formed is still being examined.
