Far into space, amongst the darkest Sea
New planets sit like marbles in a row.
We turn our eyes to find out what might be
And search for patterns in their ether’s flow;
Then try to see what else might lie below.
And as we probe how life’s rich web was spun,
Do they look back towards our distant sun?
Researchers used NASA’s Spitzer Space Telescope to make observations of the star and its exoplanets (planets which orbit a star outside our solar system) in a region of space within the Aquarius constellation, approximately forty-lightyears from Earth. This newly discovered system is called TRAPPIST-1, in honour of The Transiting Planets and Planetesimals Small Telescope (TRAPPIST) in Chile, which was used to make some of the measurements during the discovery process. Three of the TRAPPIST-1 planets lie within a region called the Habitable Zone, an area around a star in which there is likely to be rocky planets with liquid water that could potentially sustain life (i.e. the planets are neither too far nor too close to the star).
These newly discovered planets are also very close to each other. So much so that if a person were to stand on one of the planet’s surface, they could gaze up and potentially see clouds on the other planets. These observations represent a significant step forward in finding habitable environments elsewhere in the Universe, and further observations of the TRAPPIST-1 system are sure to reveal yet more secrets.
