It’s our Solar System in miniature, but could TRAPPIST-1 host another Earth?
Scientists have discovered seven Earth-sized planets, so tightly packed around a dim star that a year there lasts less than two weeks. The number of planets and the radiation levels they receive from their star, TRAPPIST-1, make these worlds a miniature analogue of our own Solar System.
Yes, We've Discovered a Planet Orbiting the Nearest Star but...
...let's not lose our minds
The third brightest star in the night sky is Alpha Centauri. It is our closest stellar neighbour, the fictional birth system of the Transformers, Small Furry Creatures and Pan Galactic Gargle Blasters… and now our closest exoplanet.
Why it is misleading to compare exoplanet Kepler-452b to Earth
NASA’s announcement of the discovery of a new extrasolar planet has been met with a lot of excitement. But the truth is that it is impossible to judge whether it is similar to Earth with the few parameters we have – it might just as well resemble Venus, or something entirely different.
No, that new exoplanet is not the best candidate to support life
In June, the popular press went wild. A planet had been discovered that was so much like Earth it was heralded as our best bet for supporting life. Positioned 16 light years away, Gliese (or GJ) 832c was a mere hop from home and there were rumours a popular coffee shop chain had already applied for planning permission.
