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.
NASA insignia. The National Aeronautics and Space Administration (NASA) logo has three main official designs, although the one with stylized red curved text (the worm) has been retired from official use since 1992. The three logos include the NASA insignia (also known as the meatball), the NASA logotype (also known as the worm), and the NASA seal.
