NASA believes the new view will change the way astronomers study the interaction between our sun and the wider galaxy.
Scientists say the new map shows a narrow ribbon of bright hydrogen emissions unlike anything in current theoretical models.
It marks the actual border between our solar system and interstellar space.
The map is based on data gathered by NASA's Interstellar Boundary Explorer spacecraft or IBEX.
For half a year, it studied particles called energetic neutral atoms.
They are created along the interstellar boundary at the outer rim of the solar system, 16 billion kilometres away.
The findings could tell scientists about an intergalactic cloud through which our Milky Way galaxy is moving and which the galaxy will leave in about 10,000 years time.
