Point of view
These three planets are the first chance to find chemical traces of life outside our Solar System
- Three Earth-like planets found
- Similar in size and temperature to our own
- More details could take 5-10 years
Scientists have found three new planets in space they say may be the most likely location for alien life they have yet discovered.
“These three planets are the first chance to find chemical traces of life outside our Solar System,” said astrophysicist Michaël Gillon.

They circle a star just 40 light-years away – the ultracool dwarf star “Trappist-1”.
They are all of a similar size, temperature and chemical composition to Earth.
They were detected using a 60cm infrared telescope based in Chile.
Exact information on their size and characteristics will take 5-10 years to obtain.
They could be in the “habitable zone” of their host star – meaning living conditions could be similar to Earth.
