Nearby Star With 7 Earth-Like Planets Discovered
WINNIPEG, MB. — NASA has discovered a nearby star with seven Earth-like planets.
Three of those are within the star’s habitable zone where liquid water could exist on the surface of the worlds.
Even more exciting, the ‘ultra-cool’ dwarf star known as TRAPPIST-1 is next door in terms of the scale of the Universe.
It takes light just 40 years to travel between our solar systems. Light from our sun takes about seven minutes to reach Earth.
In comparison, the Universe is 13.7-billion years old and is estimated to be some 93-billion light years across.
The United States space agency says they haven’t yet confirmed the atmosphere composition or whether there is water on these worlds, which are rocky like Earth and similar in size.
Some of our best telescopes are now turning their attention on TRAPPIST-1.
By studying light refracted between the star and each planet, we’ll be able to determine whether there is oxygen.
That could be a good indicator of life existing there and will also teach us plenty about what the air is like on other rocky worlds.
Lots to learn
NASA stressed a being on one of those worlds might observe our solar system and say “Hey, there’s three habitable planets there. Venus, Earth, and Mars would all be included.”
They agree there is a lot we can learn using current technology, but a lot of innovation will be needed in the coming years for further study.
