Life on Venus?

[swebby]

RAS currently giving a presentation on the discovery of phosphine in the atmosphere of Venus - this, like molecular oxygen is a key biomarker gas (an indicator of life).

I don`t think that the theory about the life on Venus is possible. This planet has extremely high pressure and more important high temperature that makes possibility of life on this planet impossible.

Basic bacterial life could potentially survive harsher environments such as Venus - pressure and temperature. Still theoretical!

I assume that bacterial life could potentially survive deep in the ground of Venus. Such point might be possible. I don`t think that Venus - pressure and temperature are still theoretical. It`s easy to explain. The atmosphere of Venus is the layer of gases surrounding Venus. It is composed primarily of carbon dioxide and is much denser and hotter than that of Earth. The temperature at the surface is 740 K (467 °C, 872 °F), and the pressure is 93 bar (1,350 psi), roughly the pressure found 900 m (3,000 ft) underwater on Earth.

Possibility of life in clouds, and at layers in atmosphere. Quite a few articles out there. All yet to be proven or disproven.

Astronomers have detected a chemical in Venus’ atmosphere that signifies life on Earth. Could it mean the same on Venus?

The comparing Mars and Venus  tells that Mars is much more better place for humans to live. Even if that was possible (switching orbit and the removal of H2SO4) , the atmosphere of Venus is around 91× denser than Earth's atmosphere, with other words, the air pressure is around 92 bar. Besides that Venus lacks a planetary magnetic field, has a very thin ozon-layer and worst of all: it rotates the wrong direction!
So from all the planets in our solarsystem, Mars is still the most survivable. Mars lacks a magnetosphere, so solarwinds can cause a problem. But with a normal Moon-spacesuite, humans should be able to survive on Mars.

Of all the rocky/solid bodies in the solar system, the surface of Venus is undoubtedly the most hostile to a human landing.  Even the robust unmanned probes that have landed there succumb to conditions within hours. The Jovian moon Io is probably second in terms of hostile environment, but that's more to do with the strong radiation field of Jupiter.

The mid/upper layers of Venus however might be tolerable for simple extromophile organisms.

The surface of Venus might be more tolerable for simple extremophile organisms or even for humans but the pressure and high temperature makes it impossible even to send crewed mission there. There are a lot of similarities between Earth and Venus but if we wanna talk about crewed mission on another planet, Mars is a better place to survive, notwithstanding the harsh environment and high level of radiation.

Yeah, NASA announced recently that it will send, not one, but two spacecraft to Venus this decade as part of its efforts to ramp up exploration of the closest planet to Earth. The decision was hailed by scientists who study Venus and have felt neglected by a space agency decidedly more interested in Mars. NASA has not sent a robotic spacecraft to Venus since the launch of the Magellan orbiter in 1989. Launched by space shuttle Atlantis, Magellan made a controlled entry into the Venusian atmosphere in 1994 after collecting reams of data that have tantalized scientists ever since."
