Detailed explanation-1: -Although the surface of Venus is like a blast furnace, a cloud layer just 31 miles below the top of its atmosphere may reach temperatures as low as 86 degrees Fahrenheit, and has a pressure similar to that at ground level on Earth.

Detailed explanation-2: -Clouds of liquid water droplets exist on Earth and on Venus (at high enough altitude that the temperature is reasonable), but clouds containing water ice crystals are found on Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Clouds of ammonia and methane are found on Jupiter out.

Detailed explanation-3: -Scientists at NASA have recently announced that they found a planet that is almost identical (about 95%) to Earth’s size and shape and has a rocky surface. Named TOI 700 e, this new planet orbits within its star’s habitable zone, which also hints at the presence of water on its surface.

Detailed explanation-4: -NASA’s Transiting Exoplanet Survey Satellite (TESS) has found two planets similar in size to Earth and within the habitable zone of star TOI 700 . We might temper our excitement though, as this is not enough to conclude that the environments of these planets are otherwise very much like Earth.
