James Webb Telescope May Detect Artificial Lights On Proxima b

• Proxima b is the nearest exoplanet to Earth at about 4.2 light years away
• The planet is likely tidally locked due to its close proximity to its red dwarf star
• This ‘tidal locking’ means one side of the world always faces the red dwarf star
• However, as the star is smaller than the Sun it is still within the habitable zone 
• Astronomers say people on Proxima b may live on the dark side of the planet 
• They would require bright lights or sunlight reflecting mirrors to illuminate them and the team predict this could be detectible by the James Webb telescope
