- Open cluster (Wikipedia)
An open cluster is a type of star cluster made of tens to a few thousand stars that were formed from the same giant molecular cloud and have roughly the same age. More than 1,100 open clusters have been discovered within the Milky Way galaxy, and many more are thought to exist. Each one is loosely bound by mutual gravitational attraction and becomes disrupted by close encounters with other clusters and clouds of gas as they orbit the Galactic Center. This can result in a loss of cluster members through internal close encounters and a dispersion into the main body of the galaxy. Open clusters generally survive for a few hundred million years, with the most massive ones surviving for a few billion years. In contrast, the more massive globular clusters of stars exert a stronger gravitational attraction on their members, and can survive for longer. Open clusters have been found only in spiral and irregular galaxies, in which active star formation is occurring.
- Bobby Hutton (Wikipedia)
Robert James Hutton (April 21, 1950 – April 6, 1968), also known as “Lil’ Bobby,” was the treasurer and first recruit to join the Black Panther Party. Alongside Eldridge Cleaver and other Panthers, he was involved in a confrontation with Oakland police that wounded two officers. Hutton was killed by the police in disputed circumstances. Cleaver stated Hutton was shot while surrendering with his hands up, while police stated he ignored commands and tried to flee.
