Sun Slower Than Previously Thought: New Finding May Upend 'Bow-Shock' Theory

The sun is zipping through interstellar space more slowly than once thought, suggesting the giant shock wave long suspected of existing in front of the sun is not actually there, researchers say.

These new findings may influence what scientists know about high-energy cosmic rays that can endanger astronauts, they added. This will also influence the Voyagers.

"Alien" Particles Found Invading Our Solar System—A First

For the first time, a NASA spacecraft has directly observed "alien" particles that came from beyond our solar system, astronomers announced today.

The discovery not only gives us a glimpse of what exists in the so-called interstellar medium—the matter between stars—but also offers clues to the anatomy of our local galactic neighborhood.
