The topic for this week’s astronomy twitter journal club (Thursday, 20:10 GMT) is Kepler-22b, a new exoplanet announced this week. However, the meeting won’t focus on the properties of this object, but rather on the media storm that’s blown up around what is being (wrongly) described as ‘Earth’s twin’.
Since the announcement many people have written many excellent articles about this planet – several are linked below, but please leave other suggestions in the comments. Finally, don’t forget to join in the discussion tomorrow.
