Find the border of the solar system

The US space agency (NASA) will put a satellite into space to understand the outer edge of the solar system.

Interstellar Boundary Explorer (IBEX) satellite will be launched from Kwajalein Atoll island in the southern Pacific on October 10. It will work for 2 years on Earth orbit.

The solar wind, a stream of charged particles released from the upper region of the sun, forms a giant protective area shaped like a bubble around the solar system called the heliosphere. At the edge of the heliosphere, the solar wind collides with dust and gas clouds in the outer space to create compression waves.

IBEX is designed to detect atoms that are heated by collisions and knocked off the edge of the sphere.

"The edge of the heliosphere helps us avoid the terrible effects of the universe. Every 6 months, we will make maps of the movement of atoms thrown off the edge of the heliosphere. From there we I can draw the shape of the heliosphere and know the characteristics of the outer dust clouds, "said Nathan Schwadron, a senior NASA expert.
