Today you learn about why the Earth's atmosphere extends beyond the moon,

whether you should listen to music while you work,

and whether your muffled hearing after a concert

means you damaged your ears.

Let's let us fast in curiosity.

A new study from Russia's Space Research Institute,

the SRI, says our atmosphere extends out to 630,000 kilometers

into space.

And this could have big implications for astronomers, including how we find exoplanets

with water.

As reported by universe today, this study centers on what's called the Geo Corona.

That's a huge cloud of hydrogen atoms that you can find where the Earth's atmosphere meets outer space.

The researchers looked at archival data from one of the instruments on the solar and

heliospheric observatory, or Soho.

Soho is a spacecraft launched in 1995 to study the sun, and it's also discovered more than 3,000 comets.

Sojo has a sensitive instrument on board that can trace the hydrogen signature from the

geocorona to find its boundaries.

See, there's a type of light that interacts with hydrogen atoms called Lyman Alpha Light.

Hydrogen atoms can both emit and absorb this light.
