Just do the numbers: hundreds of billions of stars in our galaxy. Hundreds of billions of galaxies in the observable universe. That should create lots of warm, screeching little ponds where life could come together to begin billions of years of evolution towards technology-vibrating creatures like us. With luck, it could be in the next 25 years.
If a planet is to be inhabited and not just habitable, two basic requirements must be met: the planet must first be suitable, and then life must arise on it at some point. Even the simplest bacterium is amazingly complex at the molecular level. Although we have no idea of the minimal complexity of a living organism, it is probably very high.
Orion Nebula is one of the brightest nebulae in space that is visible to the naked eye at night. Orion Nebula is actually 1500 light-years from Earth. The European Space Agency’s Hershel telescope discovered many life-forming particles, including methanol, water molecules, carbon monoxide and hydrocyanic acid, in Orion Nebula.
It can take millions of years to transform such particles into a life form. Regardless of what high-resolution Hubble Space Telescope or even amateur astronomy photographs show, it’s difficult to see colors in the nebula.
Enceladus is one of the moons of Saturn, the sixth-largest moon on the planet. NASA’s Cassini space photos show that Enceladus can hold complex life forms. Cassini spaceships discovered carbon, hydrogen and oxygen on the surface of Enceladus, key components in the formation of life.
Jets of water vapor and ice particles emerge from the subterranean ocean of Enceladus through deep icy crevasses called Tiger Stripes near the south pole of the moon and provide information on its inner functioning.
Titan is the largest moon of Saturn. But data from NASA Huygens probes show that the moon contains many organic components that lead to the origin of life. Huygen’s probe, which landed on Titan in 2005, discovered the presence of liquid water. Titan has a fully developed thick atmosphere that contains many organic compounds.
The atmosphere of titanium is largely nitrogen; Smaller components lead to the formation of methane and ethane clouds and nitrogen-rich organic smog. It creates surface features similar to those of the earth. Probably from liquid methane and ethane and deltas. The surface of the Titan is characterized by wide areas with light and dark terrain.
Europe is one of Jupiter’s natural satellites. Europe has the smoothest surface in the solar system. Oceans in Europe can support underwater life due to their chemical richness. Europe has a thin atmosphere of oxygen, but it is far too weak for people to breathe.
From the surface of Europe, Jupiter appears 24 times larger than the moon appears in our sky. Europe’s magnetic field shields its surface from the deadly radiation of Jupiter. Photos from previous missions indicate that the surface of Europe is relatively smooth, large craters and mountains are missing because convective ocean forces are constantly recycling Europe’s surface ice.
Its position on the solar system, size, atmosphere, along with data collected from the last Mars missions, show that life on the planet is possible. It proves old life on Mars. The lander of the Phoenix Mars mission collected the photo of chunks of ice on Mars, an indication of water on the surface of Mars.
NASA’s recent Mars probes spirit and opportunity gave several clues to methane presence on Mars, sounds that can live on Mars. The search for life on Mars has become more urgent, thanks in part to the probes of the two rovers now roaming the surface of Mars and another spacecraft orbiting the planet.
