A few weeks ago, the science papers were shouting there’s live on Venus, However, now it seems that it is not – and has been not habitable.
For the past decades, Venus has
been seen as a potential abode for life. For instance, models based on evolution have said that Venus had bog
oceans that they thought wuuld have kerpt live going for millions of years.
For
live to endure, it has to float - floating
in the clouds about 30 miles (50 kilometers) up,
where temperatures and pressures are similar to what we enjoy at sea level here on Earth.
However,
the new study, which was published online
Wednesday (Oct. 13) in the journal Nature, scientists led by Martin Turbet, a
postdoctoral researcher at the Geneva Astronomical Observatory in Switzerland,
simulated the climate of ancient Venus using a new model. And they came up with
very different results.
If
the scientist are right, Venus has always been warm and dry, as it is today.
This
has a message also for exoplanets: The ones that
orbit near the inner edge of the conventional habitable zone, where liquid
water can exist on a planet’s surface, might not actually be habitable,"
the authors
write.
