Found: a rocky exoplanet with an atmosphere — could it host life?

TL;DR - A Nature news article (not a peer-reviewed paper) reporting that astronomers detected helium escaping from LHS 1140b, a rocky exoplanet orbiting within its star's habitable zone, raising questions about its potential to host life. Content is thin (title plus a one-line summary), so takeaways are limited to what's stated.

• LHS 1140b is described as a rocky exoplanet located in its host star's "habitable zone," the orbital region where liquid water could exist.
• Astronomers observed helium escaping from the planet, suggesting atmospheric activity and prompting the question of whether it could be habitable.
• This is science-news coverage (Nature "d41586" news DOI), not original research, and no detailed measurements, methods, or conclusions about actual habitability are provided in the given content.
• Note: this item is astronomy, not AI-related; despite the "journal" source hint, the content is journalistic news rather than a formal research publication.
