Extraterrestrial life assembles molecules from carbon and other atoms in Chapter 5 The Emergence of Life in Bang! The Complete History of the Universe by Chris Lintott, Brian May and Patrick Moore.
Extraterrestrial life becomes Earth-like and possible if carbon-based in a free oxygen atmosphere, on liquid or solid surfaces, with adequate water, equable temperatures and slow-changing conditions. It configures regular day-lit, night-darkened alternations since, without dark-interfacing, light-interfacing terminator boundary zones, one boiling illuminated side and one freezing dark side convoke rainless, violent winds. The habitable Goldilocks zone of Baby Bear-friendly temperatures describes Earth, not too hot Venus too close to, or too cold Mars too distant from, our Sun.
Perhaps one in every 100 in five billion planets out of the Milky Way Galaxy's 20 billion planets entail carbon-based extraterrestrial life in Goldilocks zone-friendly conditions.
Mars perhaps functions as the likeliest candidate for carbon-based extraterrestrial life with an albeit tenuous atmosphere, rotations 30 minutes longer than Earth's and tolerable surface temperatures.
No naturally adequate shield gives above-ground protection from harmful space radiation to carbon-based extraterrestrial life so any Martian life necessarily gets year-in, year-out underground living arrangements. Mars Exploration Rovers MER-A Spirit's (Jan. 2004-March 22, 2010) and MER-B Opportunity's (Jan. 2004-) hydrogeological information-gathering heralded Mars as a previously warm water-world with huge seas. Northern arctic regions include large quantities of water as ice, whose sampling the Phoenix spacecraft robotic arm implemented in 2008 and perhaps as occasional water spouts.
Perhaps extraterrestrial life, carbon-based or otherwise, once journeyed, or still journeys, through life cycles above or below Martian surfaces where environmental conditions jeopardize, or not, sustainability.
Perhaps one of 200 billion galaxies kindles extraterrestrial life, whose inevitable intelligence, unless only Earthlings key into intelligence, minimally knows our twentieth and twenty-first-century technological levels.
Civilizations capable of communication perhaps last long enough to languish from natural disasters, such as ancient Earthly cultures, or their own follies, perhaps such as ours. Interstellar travel mandates technological breakthroughs for us to meander outside our Solar System since modern spacecraft and rocket travel means centuries-long interstellar and years-long intra-galactic movements. Albert Einstein's (March 14, 1879-April 18, 1955) Theory of Special Relativity noted necessarily infinite amounts of energy negating human navigation at 300,000-mile (186,000-kilometer) light-speeds per second.
Radio waves operate at light-speeds and offer, for example, 11-light-year one-way, 22-light-year round-trip interstellar communications between observational astronomers on Earth and a planet orbiting Tau Ceti.
Nonreactiveness by 2031 to coded, mathematics-based artificial transmissions in 2009 to Epsilon Eridani perhaps proves Earthling-only intelligence, flawed experiments or technological civilizations over 11 light-years away.
The three authors quote Percival Lowell's (March 13, 1855-Nov. 12, 1916) qualifying extraterrestrial life as peaceful questers who quit far-off, technologically advanced civilizations for Earthly visits. Fred Hoyle's (June 24, 1915-Aug. 20, 2001) and Chandra Wickramasinghe's (born Jan. 20, 1939) theorized comet-released, pandemic viruses that ravage Earth resists our receiving extraterrestrial life. Solar hyperluminosity, not comet-sent, Earth-savaging, upper-atmospheric viruses, perhaps stops Francis Crick's (June 8, 1916-July 28, 2004) and Leslie Orgel's (Jan. 12, 1927-Oct. 27, 2007) directed panspermia.
The Crick and Orgel theory transports micro-organisms in the transgalactic spaceship of technologically advanced extraterrestrial life that perhaps tries nothing, or something, to trump solar hyperluminosity.
