Hydrogen Volcanoes?

In a thought provoking article found on Sciencenews.org, scientists have found evidence linking the existence of hydrogen belching volcanoes to the possibility of life supporting planets.

Atmospheric models suggest, according to the article, these volcanoes may extend a star's habitable
zone considerably. This is exciting news for the exoplanet hunting community that opens the potential for many more worlds which may harbor life. It's an exciting time in the world of exoplanet astronomy and for lovers of science, like myself. Now, we just need a means of propulsion that will get us to these far-flung worlds in a timely manner rather than say the 750,000 years it would take us to get to the Trappist-1 system currently.
