Many science fiction movies and television shows have toyed with the idea of
strong stellar winds, resulting from coronal mass ejections, blowing away
Earth's atmosphere. While those ideas mostly remain in the realm of space
science fiction, especially in shorter time frames, the same can't be said for
some planets outside our solar system, where stellar winds (a broader term)
strip entire planets of life.

> five times greater than the average speed of our Sun's solar wind. In other
> words, exoplanets orbiting those cool stars are subject to stellar winds
> traveling as fast as 5 million miles per hour.

According to Space.com, cool stars with powerful magnetic fields could have
stellar winds so harsh that they play out the sci-fi scenario in real life,
stripping entire atmospheres of orbiting planets, rendering them incapable of
hosting life.

These findings stem from various simulations conducted by the Leibniz Institute
of Astrophysics Potsdam, and they could provide crucial information in our quest
to find extrasolar planets, also known as exoplanets, that are capable of
sustaining life. Space truly is the final frontier, after all.

The researchers at AIP found that certain charged particles of strongly magnetic
cool stars could reach speeds up to five times greater than the average speed of
our Sun's solar wind. In other words, exoplanets orbiting those cool stars are
subject to stellar winds comprised of charged particles, traveling as fast as 5
million miles per hour.




HOW STRONG ARE STELLAR WINDS?

That's 6,000 times the speed of a bullet fired by a handgun. And, as you might
imagine, such winds are strong enough to completely blow away the atmosphere in
outer space and destroy the conditions needed to support life on those planets.




Now, we're not astrophysicists, but allow us to provide at least some context,
courtesy of countless Star Trek episodes and space documentaries. Most stars
have something called a Goldilocks Zone, which is a region around a star where
the conditions allow for water liquid to exist on the planet's surface, assuming
that the planet has a suitable atmosphere.

However, this doesn't mean that the planet or planets within the habitable zone
will have life or even liquid water. Other factors, such as atmosphere and
magnetic field, play crucial roles. So, what does that have to do with solar
winds?

Stellar winds consist of charged particles ejected from stars, and when these
collide with the planet's atmosphere, they can impart energy to the atmospheric
molecules. If the space winds are strong, the atmospheric molecules might
achieve escape velocity and leave the planet.




Without the atmosphere, there would be an immediate loss of pressure, which
would cause all the water on the surface of the planet to evaporate and then
freeze. If that were to happen to our Earth, the average temperature would drop
to -0.4°F (-18°C). Also, the sky would be pitch black, even during the daytime.



Fortunately for us, the Earth has a pretty strong magnetosphere, so our
atmosphere isn't likely to just disappear due to stellar winds. However, the
simulation conducted by the scientists plays a crucial role in developing a very
sophisticated observational model for searching for other habitable,
life-harboring planets in outer space.

We can now observe certain stars, their gravity, magnetic field strength,
rotation periods, and other properties to determine whether the planets in their
habitable zones can actually host life.

The research of stellar winds and how they interact with other celestial bodies
further deepens our understanding of space and charts a somewhat clear course
for potential space exploration once the technology for effective space travel
has been developed.
