Enlarged Spleen Overview. The spleen is an important organ in the immune system. It is a bean shaped structure, located in the left upper portion of the abdominal cavity, under the diaphragm, tucked in between the 9th and 11th ribs, in the mid-back.
Chandra and NASA's Hubble Space Telescope later collected data from the event's afterglow, and together the observations led astronomers to conclude that the powerful explosions can result when a black hole and a neutron star collide, producing another black hole.
How likely is it that a black hole could enter the Solar System? Well, youâd have to define likely; it is more likely that the Earth will get swallowed by a black hole than, say, winning the lottery ten times in a row, but less likely than being struck by lightning. In fact the odds of a black hole devouring our planet are estimated at one in a trillion.
