A new study funded by the National Aeronautics and Space Administration (NASA) has revealed that the heliosphere of the sun is dominated by two giant jets of material that blasts over the star’s south and north pole…

According to a NASA statement, a new NASA-funded study led by Merav Opher of Boston University has found that the bubble formed by the Sun’s magnetic field, the heliosphere, is defined by, not one, but rather two jets of solar wind…

NASA-Funded Study Finds Two Solar Wind Jets in the Heliosphere

As the sun skims through the galaxy, it emits charged particles in a stream of plasma called the solar wind. The solar wind, in turn, creates a bubble known called the heliosphere that extends far beyond the planets of the solar system…

Expert quote:

“Everyone’s assumption has been that the shape of the heliosphere was molded by the flow of interstellar material passing around it. Scientists thought the solar wind flowing down the tail could easily pull the magnetic fields in the heliosphere along as it flowed by, creating this long tail. But it turns out the magnetic fields are strong enough to resist that pull – so instead they squeeze the solar wind and create these two jets.”

As our Sun moves through the Milky Way, it leaves a trail of particles known as the solar wind in its wake. The solar wind then forms a protective shell called the heliosphere, which guards us from galactic cosmic rays…

Expert quote:

“Most researchers don’t believe in the importance of the solar magnetic field, because the magnetic pressure on the solar wind’s particles is far lower than the thermal pressure of the particles.”

For the first time in history, we’ve left the solar system…

Expert quote:

“It really is a milestone. It’s the first man-made object to cross the last boundary that separates our home. Voyager is like our spy that we sent to tell us what lies beyond our home.”

We’ve made it to the stars, at last…

Expert quote:

“The historic crossing is extremely dramatic and very romantic, but also bittersweet. … I wish Voyager 1 could’ve stayed longer at the brink of interstellar space. Such a pity it left. I wanted more data.”
