What happened

We might soon have the technology to reach other star systems Gaby Clark Scientific Editor Andrew Zinin Chief Editor The recent confirmation of an atmosphere around a rocky exoplanet called LHS 1140b has created a wave of interest within the astronomy…

Why it matters

The planet orbits within the habitable zone around its parent star—a red dwarf located some 48 light-years from Earth.

Common ground

The habitable zone is the region around the star where temperatures are just right for water to remain liquid at a planet's surface.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
