15th July Lecture: TRAPPIST-1 System of Exoplanets

In Natalie Heron’s talk she outlines that we’ve possibly found a new solar system, and it threatens to put our own to shame.

The star Trappist-1, a mere 39 light years away, has been found to host seven Earth-sized, rocky planets.

The discovery has astronomers, alien-hunters, and space enthusiasts abuzz for a good few reasons. Among new solar systems discovered so far, none have had more than seven planets (our system has eight). And none have had all seven that were rocky and also Earth-sized.

What’s more, because the star type is among the most common in our galaxy, such solar systems are likely to be quite common. That makes the Trappist-1 system a prime target to accelerate the search for life beyond our own solar system.
