No, so far we have found no life in outer space. Life may well exist in outer space, but we haven't found it yet.
As an astronaut, I can tell you that yes, there is life in outer space, but to an extent. Traces of bacteria and other forms of living organisms has been found on Mars, but outside our Milky Way lies great mystery in whether there are any living organsims.
In outer space, there has been no definit proof that life exists, but there is proof that there was once water on mars, creating the possibility of life. In extreme heat or cold, there have been bacteria that have been found.
They study how long to get to planets and if there is life in outer space.
Well, we can be considered that, seeing as we are life on an outer space planet, but technically, since we are the only life, anything else that is found is considered an alien.

Astronomy is the study of heavenly bodies.
None has been found yet, but it may still be found in the future - not much of space has been explored yet.
No plants or life of any description have yet been found in space.
Exobiology.
Exobiology, is ths study of phenomena occurring in the upper atmosphere or celestial objects in outer space.
It is impossible to know at our stage of development. Humans today can only see a small part of space. Maybe one day human or robots can adventure into space and possible find life in outer space.
I'm not exactly sure what you mean by outer planet... But it is a planet in outer space. Astronauts have been trying to see if there's been life on Mars. They've had space robots go up and take pictures. Hope I helped! =)
