Crunching the numbers leaves little doubt in the minds of many scientists and broad thinkers
Space news – We can estimate the number of galaxies and thus approximately how many stars there are in the universe. Can we extrapolate the number of possible intelligent lifeforms in the universe? Lifeforms with an advanced civilization and technology?
NASA astronomers are finding more and more planets orbiting distant stars using the Hubble Space Telescope. Space scientists on Earth find microbes still surviving after thousands of years frozen in ice and thriving in environments we once thought hostile to life.
Astronomers estimate the Milky Way contains around 400 billion suns, give or take a few. Sol is only one of these stars. They also estimate the universe holds a minimum of 125 billion galaxies.
If we crunch the numbers a bit, we find the universe contains roughly 400 X 125 billion billion, or 50,000 billion billion stars. We won’t at this time include the number of planets per sun in the universe, which would make our estimate even less precise. NASA space scientists and astronomers haven’t determined this number and the knowledge we have now isn’t sufficient enough to come to even a rough estimate.
How many of these suns have intelligent life living on a planet in orbit with a highly advanced civilization and technology? In future articles, we’ll try to narrow this number down a bit, by estimating the number of intelligent life forms in the Milky Way.

Surviving space is going to be hard
Astronomy News – Planets circling twin stars close in proximity could be a real tough place for life to begin, according to the conclusions of a study conducted using data from NASA’s Spitzer Space Telescope. Space scientists using NASA’s infrared observatory recently found what they believe to be clouds of possible dust around three mature, close-orbiting binary stars. Dust that scientists think is possibly the result of the planets orbiting these twin stars colliding, which could make living on these planets difficult for any lifeforms that might have arisen on these planets.
Planetary collisions are possible real-life science fiction in action, as the reasons for the dust clouds are certainly a matter of conjecture and something that any science fiction writer is going to be able to spin a tale of annihilation around. Lifeforms evolving under the environmental conditions that possibly exist on planets orbiting binary stars of the particular class studied would certainly be something beyond the imagination of any human writer. It’s unlikely that anything we humans create using our imaginations could ever match the possibilities that exist in space and time. The finite imaginations of humans are limited by our senses, experiences and the limits of what we refer to as our human perception or intelligence to some.
Lifeforms evolving on these planets would have to survive possible planetary collisions at regular intervals if space scientists conclusions are correct? If they have the ability to sense the world beyond their normal lives? Lifeforms existing on these planets could be non-sentient and unable to perceive the annihilation above them. They could be looking up at annihilation coming toward them in the form of another planet, asteroid, or other celestial body orbiting the binary star systems in question. They may have been destroyed in a recent collision between planets and are space dust, once again. The view would be a spectacular one, though, with two huge suns that would exceed anything we experienced viewing the double stars systems in the Star Wars Saga.
Humans will evolve on any new planet they inhabit
Life evolving on planets circling binary stars like the ones in question would have a limited time to evolve into a space traveling sentient race as well. The suns in the binary star system they have evolved on are slowly circling closer and closer, according to astronomers, which could possibly make surviving and evolving on these planets a lot more difficult. Lifeforms surviving and thriving on these planets would likely be a survivor beyond human imagination, so we should probably thank our lucky stars that they aren’t likely to be stopping by for a visit, anytime soon.
