WHAT IS VENUS?
Venus is the second-closest planet to the Sun in the Solar System.
NASA explains that it¡¯s around 67 million miles from the Sun,
three-quarters the distance of the Earth to the Sun.

Venus is actually closer to Earth.

Venus seems an unlikely candidate for life.
The temperature at the surface is 887 degrees Fahrenheit
(475 degrees Celsius), hot enough to melt lead.
The pressure is 90 times higher than on Earth.
And the atmosphere is filled with sulfuric acid.
Earth-like, it ain¡¯t.

And yet conditions in the atmosphere some 37 miles (60 kilometers)
above ground are more hospitable.
Here the temperature and pressure are much closer to Earth¡¯s.
Indeed, astronomers and space scientists have long gathered evidence
that something strange is occurring in this region of the Venusian atmosphere.

The goal would be to send a probe to around 30 miles¡¯ altitude,
where the atmospheric conditions are a bit closer to those found on Earth.

Research suggests Venus was once a more habitable planet.
A 2019 study from NASA's Goddard Institute for Space Studies found that
Venus could have had shallow oceans on the surface for two to three billion years.
