Just to the east of the swimming pool is a very large playing field and a small playground with bench. In addition, you can pick up Trail 8, which serves as a shortcut to the campgrounds, at the west end of the swimming pool. 1  The pool is open:  11:00 am to 7:00 pm Sunday - Thursday.
A quasar is believed to be a supermassive black hole surrounded by an accretion disk. An accretion disk is a flat, disk-like structure of gas that rapidly spirals around a larger object, like a black hole, a new star, a white dwarf, etc.
The quasar group appears to violate a widely accepted assumption known as the cosmological principle, which holds that the universe is essentially homogeneous when viewed at a sufficiently large scale. Calculations suggest that structures larger than about 1.2 billion light-years should not exist, researchers said.
