Thoughts #8 – On NASA’s Exoplanet Discovery ‘Beyond Our Solar System’

I heard the news that NASA was going to announce a breakthrough discovery a couple of days ago and as an astrophysics enthusiast, I was extremely excited.

Today, 22nd February 2017, NASA announces the discovery of seven new exoplanets orbiting a star – Trappist-1 only 40 light years away. Not only is this a record on its own, the content of the discovery is as or more so intriguing. Yes, we are talking about these as planets that could potentially support life. Each and every one of them are rocky resembling the inner four planets within our solar system – Mercury, Venus, Earth and Mars, and all have been claimed to have the possibility of supporting liquid water on their surfaces. The discovery is not only astonishing in this essence but also of the fact that Trappist-1 is rather small and dim allowing them to be temperate, thus perhaps be home to life.

Even though only three out of seven of the planets lie within the ‘Goldilocks Zone’ of the star system, this discovery opens up more pathways for interstellar exploration into these worlds, enables further research on their atmospheres and gives us a fairly good chance of looking for clues about life out with Earth.

Till next time,

Susan
