Outer space is everywhere outside of an atmosphere. It is simply the space between celestial bodies.... Space which is outside the earth's atmosphere and especially that part lying beyond the earth-moon system…. That is called space….

The early era of space exploration was driven by a "Space Race" between the Soviet Union and the United States.

About Telescope - The first telescope was said to be invented in 1608 in the Netherlands by an eyeglass maker named Hans Lippershey.
But Galileo Galilei built the first telescope in 1609 to see in space which was very famous.

First outer space human made object …..
The Bumper-WAC reached an altitude of 393 kilo metres (244 mi) in 1949, becoming the first human-made object to enter space…

First human outer space flights…
The first successful human spaceflight was Vostok 1 ("East 1"), carrying the 27-year-old Russian cosmonaut, Yuri Gagarin, on 12 April 1961. The spacecraft completed one orbit around the globe, lasting about 1 hour and 48 minutes. Gagarin's flight resonated around the world

First interstellar space flight….

Interstellar means in a simple word …… Inter' means between and 'Stellar' refers to stars… this is boundary between the space near a star and the space in between stars….

Voyager 1 was launched by NASA on September 5, 1977. Part of the Voyager program to study the outer Solar System, Voyager 1 was launched 16 days after its twin, Voyager 2

Voyager 1 became the first human-made object to leave the Solar System into interstellar space on 25 August 2012. The probe passed the heliopause at 121 AU to enter interstellar space.
