However, there are many extreme and chemically harsh ecosystems on Earth that do support forms of life and are often hypothesized to be the origin of life on Earth. Hydrothermal vents , [ 9 ] acidic hot springs, [ 10 ] and volcanic lakes [ 11 ] are examples of life forming under difficult circumstances, provide parallels to the extreme ...
Life in the atmosphere brown dwarfs was also discussed by Yates et al. in 2017, and in 2019 Manasvi Lingam and Abraham Loeb extended the discussion of Yates et al.. Both articles extend the viability of Earth-like biological life beyond planets. [8] [9] Their ideas were criticized by experts in brown dwarfs. [10]
The following outline is provided as an overview of and topical guide to extraterrestrial life: Extraterrestrial life – is any type of lifeform, from prokaryotes to intelligent beings, that is neither native of Earth or transplanted from it. So far, no extraterrestrial life has ever been found. [1]
This is an accepted version of this page This is the latest accepted revision, reviewed on 27 January 2025. Problem of the lack of evidence for alien life despite its apparent likelihood This article is about the absence of clear evidence of extraterrestrial life. For a type of estimation problem, see Fermi problem. Enrico Fermi (Los Alamos 1945) The Fermi paradox is the discrepancy between ...
Altogether, these three developments in science presented the wider scientific community with a seemingly paradoxical situation regarding the origin of life: life must have evolved from non-biological precursors after the Earth was formed, and yet spontaneous generation as a theory had been experimentally disproved.
Scientists have found a new Earth-like planet that could support alien life – just 40 light-years away.. The planet is a remarkable discovery in the search for habitable worlds: it is slightly ...

While Earth is the only place in the Universe known to harbor life, [10] [11] estimates of habitable zones around other stars, [12] [13] along with the discovery of thousands of exoplanets and new insights into the extreme habitats on Earth where organisms known as extremophiles live, suggest that there may be many more habitable places in the ...
