What happens when the solar wind suddenly starts to blow significantly harder? According to two recent studies, the boundaries of our entire solar system balloon outward — and an analysis of particles ...

Our corner of the universe, the solar system, is nestled inside the Milky Way galaxy, home to more than 100 billion stars. We’re protected from that radiation by the heliosphere, which itself is ...

Surrounding our solar system is a natural and enigmatic cosmic shield called the heliosphere — and a new mission has launched to help astronomers better understand it. Created by the solar wind, a ...

The heliosphere, a region dominated by the Sun's influence, extends far beyond the orbits of known planets and acts as a shield against cosmic rays, protecting the inner solar system. Voyager 1 and 2 ...

Far, far beyond the orbits of the planets lie the hazy contours of the magnetic bubble in space that we call home. This is the heliosphere, the vast bubble that is generated by the Sun's magnetic ...

As the solar wind flows out from the Sun at supersonic speeds, it blows up a bubble known as the heliosphere. The heliosphere encases all the planets in our solar system and much of the space beyond ...

Now, for the first time, scientists have used an entire solar cycle of data from NASA's IBEX spacecraft to study how the heliosphere changes over time. Solar cycles last roughly 11 years, as the Sun ...
