Feeling Isolated? The Universe is Closer Than You Think

 The heliosphere is interacting with the galaxy more than we thought 

IBEX recently completed a six-month job. The sky map below is the result.


The human journey to the beginning of space and time continues

 Astronomy News – Mankind is preparing to journey to the outer solar system in the decades ahead and part of the preparation is using NASA’s Interstellar Boundary Explorer, or IBEX, spacecraft to take a look at conditions on the edge of the solar system to get an idea of the environment humans and the spacecraft we send to the edge of the solar system will have to withstand to survive. NASA’s Interstellar Boundary Explorer has just finished producing a new set of maps of the dynamic conditions that exist near the boundary between the local interstellar medium of the galaxy and our own heliosphere. The Interstellar Boundary Explorer spacecraft creates sky maps of the outer solar system by counting and measuring particles astronomers call energetic neutral atoms that are created near the interstellar boundary region in collisions between charged particles emanating from Sol and star-dust between the stars. These collisions send energetic neutral atoms towards Sol at velocities ranging from 100,000 to 2.4 million miles per hour.
Six months of observations later, this is the result

Dynamic universe

Astronomers looking at the edge of the solar system using the Interstellar Boundary Explorer recently announced that their views of the edge of the solar system over a six month period have revealed the outer solar system is a lot more dynamic than scientists first thought. That interaction between the solar wind and the interstellar medium on the other side of the interstellar boundary region are constantly changing as we move through space and time. The first map produced indicates an unpredicted bright ribbon of energetic neutral atoms emanating toward Sol from the edge of the solar system. A bright ribbon that currently has scientists studying the heliosphere scratching their heads in a confused manner because this scenario doesn’t fit any of the preconceived models they had created of the conditions and environment near the outer solar system.
