The sun and all that surrounds it — us included — are having a slower ride through space than originally thought, new findings from a NASA satellite show.
Precise measurements of neutrally charged particles such as helium flowing into the solar system from interstellar space show the heliosphere — the region of space under the sun’s influence — is moving at 52,000 mph relative to the outside environment.
That’s a change from 59,000 mph measured by NASA’s now-defunct Ulysses spacecraft.
