Sketch of Hertzsprung–Russell diagram of a globular cluster, showing blue stragglers. A blue straggler is a type of star that is more luminous and bluer than expected. . Typically identified in a stellar cluster, they have a higher effective temperature than the main sequence turnoff point for the cluster, where ordinary stars begin to evolve towards the red gi
The study of plant research has yielded information useful to other areas of botany and horticulture. Extensive research into hydroponics systems was fielded successfully by NASA in both the CELSS and ALS programs, as well as the effects of increased photoperiod and light intensity for various crop species.
