  1. Challenges to Life on Venus:
    • Extreme temperatures, volcanic activity, and acidic rain on Venus make it inhospitable for extraterrestrial life.
    • The composition of Venus' clouds does not support life, prompting scientists to explore other celestial bodies like Jupiter.
  2. Surface Temperature of Venus:
    • Venus experiences surface temperatures ranging from approximately 820 to nearly 900 degrees Fahrenheit, with an average of 847 degrees Fahrenheit.
    • Such high temperatures render the planet's surface unsuitable for life as we know it, with conditions hot enough to melt lead.
  3. Potential for Life in Venus' Clouds:
    • While direct evidence of life on Venus remains elusive, scientists suggest the possibility of aerial life-forms within Venus' clouds.
    • Despite the planet's harsh surface conditions, its dense cloud cover could provide milder environments conducive to microbial life, supported by sunlight, nutrients, and limited water.
  4. Speculations on Life Existence:
    • Speculations vary regarding potential habitable zones on Venus, with some suggesting narrow strips of land as possible locations for life survival.
    • Researchers from Cambridge University propose that studying Venus' atmosphere could offer insights into similar planetary atmospheres across the galaxy, aiding the search for extraterrestrial life.
  5. Detection of Phosphine Gas:
    • Recent observations and analysis by the Massachusetts Institute of Technology indicate the presence of phosphine gas in Venus' clouds.
    • While the origin of phosphine remains debated, its detection has reignited discussions about the possibility of life on Venus, with researchers proposing alternative theories.
  6. Hospitable Environment Hypothesis:
    • New research suggests that Venus may have had a hospitable environment within two to three billion years after its formation.
    • This hypothesis raises the possibility that life could have emerged on Venus during this early period, offering new perspectives on the planet's history and potential for life.

Scientists may have eliminated the possibility of extraterrestrial life on Venus due to extreme temperatures, volcanic activity, and acidic rain. It turns out that the clouds of Venus are not made from the suitable material for supporting life - and that is why scientists are now turning instead to Jupiter. Now, in a startling twist, scientists from the Massachusetts Institute of Technology, Cardiff University, and other institutions have observed signs that could indicate life inside Venus clouds.

What is The Temperature on Venus?

The surface temperature of Venus ranges from about 820 degrees to nearly 900 degrees F. The average surface temperature is 847 degrees F., this is hot enough to melt lead.

Although scientists at MIT have found no direct evidence of living organisms there, if what is being observed is associated with life, then it should be a kind of aerial life-form in Venus clouds – the only livable part of an otherwise scorched, uninhabitable world. Despite features that render the planet's surface inhospitable, Venus's dense blanket of global clouds could provide mild conditions for some microbes, thanks to sunlight, nutrients, and a small quantity of water available - all the ingredients for creating tight yet habitable zones, such as the ones that are thought to exist higher up the planets thick atmosphere. Satellites orbiting Venus provide more profound views into its atmosphere and have provided clues about potentially living things that are snaking around the tight pockets high up in Venusian skies. Scientists speculated that if liquid water existed at the Venusian surface prior to the planet's warming by the runaway greenhouse effect, then microbial life could have formed on Venus, but that may not be the case.

Scientists speculate, with significant disagreement, that if life existed on Venus, a narrow strip of land is probably the only place where it could survive. Venus, says Limaye, also experiences a limited amount of UV flow through the clouds at mid- to lower levels, which further enhances its potential for containing life. Even if Venus is lifeless, Cambridge University researchers say their findings, reported in the journal Nature Communications, may prove valuable in studying similar planet's atmospheres across the galaxy and eventually uncovering life beyond our solar system. Based on many scenarios they considered, the scientists concluded there is no explanation for the phosphenes detected in our other clouds except for the existence of life.

The Massachusetts Institute of Technology team followed the observations up with a thorough analysis of whether something other than life might have produced phosphine in the hospitable, sulfuric Venusian environment. The research, conducted last year, renewed hopes that Venus might be supporting life after researchers detected the phosphine gas, produced by bacteria on Earth, in more temperate clouds at Venus. A group of researchers has proposed a new theory suggesting that possible life on Venus may make its environment more hospitable. According to new research, the infernal planet Venus could have had an entirely hospitable environment within two or three billion years after the planet formed, suggesting that life could have had plenty of time to arise there.
