- Panama Plate (Wikipedia)
The Panama Plate is a small tectonic plate (microplate) that exists between two actively spreading ridges and moves relatively independently of its surrounding plates. The Panama Plate is located between the Cocos Plate and the Nazca Plate to the south and the Caribbean Plate to the north. Most of its borders are convergent boundaries, including a subduction zone to the west. It consists, for the most part, of the countries of Costa Rica and Panama.
- Messier 53 (Wikipedia)
Messier 53 (also known as M53 or NGC 5024) is a globular cluster in the Coma Berenices constellation. It was discovered by Johann Elert Bode in 1775. M53 is one of the more outlying globular clusters, being about 60,000 light-years (18.4 kpc) light-years away from the Galactic Center, and almost the same distance (about 58,000 light-years (17.9 kpc)) from the Solar System. The cluster has a core radius (rc) of 2.18 pc, a half-light radius (rh) of 5.84 pc, and a tidal radius (rtr) of 239.9 pc.
