A lot of the enthusiasm revolves around the hope that one of these planets might harbor extraterrestrial life or could be suitable for human inhabitants. Of course, many further observations must be made to determine if these scenarios are plausible, not to mention the huge advances in technology that would need to occur so we could actually verify the planetary conditions or send humans 40 light-years away.
