Subrahmanyam Chandrasekar was a Nobel prize winning Indian born Physicist who did extraordinary work in advancing various areas of Physics. He showed that the mass of a white dwarf could not exceed 1.44 times that of the Sun. This idea was ridiculed at first and has subsequently been widely accepted. The Chandra X-ray observatory was named after him. Celebrate Great Scientists with more Physics T shirts.

By the mid-22nd Century, all major space-faring powers have established observatories on the far or "dark" side of the Moon. Insulated from Earth's ceaseless radio chatter by 2,159 miles of Lunar rock, telescopes now probe the depths of cosmic time and space with an unprecedented clarity. Nearly 150 astronomers now work in these isolated little colonies where the Earth is forever hidden beneath the horizon. It is perhaps not surprising then that the observatory based at the crater Tsiolkovskiy has come to possess a particularly symbolic value, haunted as it is by the words of the long-dead visionary whose name it bears: "Earth is the cradle of humanity, but one cannot remain in the cradle forever."

Sagittarius A* is believed to be a supermassive black hole at the center of the milky way galaxy. The event horizon is the area around a black hole in which the force of gravity is so strong that electromagnetic radiation cannot escape.
