Black holes form when a star at least three times bigger than the sun is destroyed and the suction power just pulls you in being called a black hole from which their is no return. They are objects so dense that sense nothing is faster than light, nothing can escape a black hole. They would say that anything with the same mass and same distance away would still get sucked inside the black hole. The mass of a super massive black hole can be measured using radio astronomy.

Pluto is a dwarf planet that is now no longer considered one of our planets. In Greek it means Hades which is the god of the underworld. It was given this name because of its distance from the Sun makes it so dark. Did you know that Pluto was discovered by accident. It is very small and located in the Kuiper Belt. Pluto's radius is unknown and is most likely to be found somewhere in the next five years. Pluto can also reach certain temperatures such as -235 and -210 C.

Andromeda Galaxy has been said that it is possibly brighter than the Milky Way. It is a spiral galaxy and is located northwest of Mu and Beta. The Andromeda Galaxy has a diameter of over 200,000. It also has been suggested that Andromeda holds anywhere from 700 billion to 1.2 trillion Solar-masses. It was found in the 1990s that the Andromeda Galaxy has a nucleus with a double feature

Constellations are groups of stars that form pictures or collections of 88 different star groups. They can even be further divided into eight different families. The Greeks used to assign certain heroes or gods after pictures in the sky. Regions later on around the south pole got their names from the Astronomer Johan Bayer who followed the tradition of names brought from the sea and its creatures.

Apollo Missions contained 17 missions and most of them were somewhat successful. In Apollo mission 1 a fire broke out and killed three U.S. astronauts but in Apollo mission 7 it was the only manned mission launched on a Saturn 1-B rocket from pad 34 at the Kennedy Space Center. In this mission the crew circumnavigated Earth 163 times and spent 10 days and 20 hours. In Apollo mission 10 it was the second one to orbit the moon but the very first one to travel there and receive information about the Moon. Also their was much going on in Apollo mission 11 they returned to earth with the first samples of foreign body masses.
