Astronomers Admit: We Were Wrong—100 Billion Habitable Earth-Like Planets In Our Galaxy Alone



Estimates by astronomers indicate that there could be more than 100 BILLION Earth-like worlds in the Milky Way that could be home to life. Think that’s a big number?

According to astronomers, there are roughly 500 billion galaxies in the known universe, which means there are around 50,000,000,000,000,000,000,000 (5×1022) habitable planets. That’s of course if there’s just ONE universe.
In fact, just inside our own Milky Way Galaxy experts now believe are some 400 BILLION STARS, but this number may seem small as some astrophysicists believe that stars in our galaxy could figure the TRILLION. This means that the Milky Way alone could be home to more than 100 BILLION planets.


However, since astronomers aren’t able to see our galaxy from the outside, they can’t really know for sure the number of planets the Milky Way is home to. They can only provide estimates.
To do this, experts calculate our galaxy’s mass and calculate how much of that mass is composed of stars. Based on these calculations scientists believe our galaxy is home to at least 400 billion stars, but as I mentioned above, this number could drastically rise.
There are some calculations which suggest that the Milky Way is home on an average between 800 billion and 3.2 trillion planets, but there are some experts who believe the number could be as high as eight trillion.

Furthermore, if we take a look at what NASA has to say, well find out how the space agency believes there are at least 1,500 planets located within 50 light years from Earth. These conclusions are based on observations taken over a period of six years by the PLANET—Probing Lensing Anomalies NETwork—collaboration, founded in 1995. The study concluded that there are way more Earth-sized planets than Jupiter-sized worlds.
In 2013, Dr. Phil Yock, from the department of physics at the University of Auckland said how: “Kepler finds Earth-sized planets that are quite close to their host stars, and astronomers estimate that there are around 17 billion such planets in the Milky Way.


These worlds are hotter than our planet, although some could be of a comparable temperature (and could, therefore, be habitable) if they are orbiting a cool star called a red dwarf.”
“Our proposal is to measure the number of Earth-mass planets orbiting stars at distances typically twice the Sun-Earth distance. Our planets will, therefore, be cooler than the Earth. By interpolating between the Kepler and MOA results, we should obtain a good estimate of the number of Earth-like, habitable planets in the Milky Way. We predict a number in the order of 100 billion. Of course, it will be a long way from measuring this number to actually finding inhabited planets, but it will be a step along the way.”
The number seems to be increasing every year, which is kinda cool.
If we take a peek at the recent data provided by the Kepler space mission, we’ll find how astronomers believe approximately 40 BILLION Earth-sized planets orbiting habitable zones of Sun-like stars and red dwarfs in the Milky Way galaxy alone.

Since NASA’s Kepler was launched in 2009, the space telescope has discovered a total of 4,034 potential alien planets, of which 2,335 are verified exoplanets. Interestingly, some astronomers say that around 11 billion planets may be orbiting Sun-like Stars, while other believe this number is more like 100 billion.
In 2017 NASA made great progress in the search for alien planets. Their most noteworthy discovery was the solar system Trappist-1, home to SEVEN Earth-like planets who may even be home to alien life. This particular solar system is very important.

In June of 2017, NASA revealed a statement saying that they had discovered ten new planets outside of our solar system that are very likely of similar size and temperature as Earth and may even have life developed on their surface.

  1. On the basis of information available, I say bullshit but your mileage may vary.

    ...like we have so many verified contacts w life from other planets!

    While increasing numbers of planets might increase the chances of other life existing, given the complexities necessary to initiate & sustain life (something mankind obviously has much to appreciate given current casual disregard for our collective futures) it is just as likely that planet Earth IS unique & represents the on in a trillion trillion trillion....

  2. Then we have this paragraph, which finally references a study; but a careful read says it's talking about something totally different, just the 1,500 planets they estimate are within 50 light years of the Earth:

    "Furthermore, if we take a look at what NASA has to say, well find out how the space agency believes there are at least 1,500 planets located within 50 light years from Earth. These conclusions are based on observations taken over a period of six years by the PLANET—Probing Lensing Anomalies NETwork—collaboration, founded in 1995. The study concluded that there are way more Earth-sized planets than Jupiter-sized worlds."

    Or this part, which clarifies that all of those planets may be Earth like, but not exactly habitable:

    "In 2013, Dr. Phil Yock, from the department of physics at the University of Auckland said how: “Kepler finds Earth-sized planets that are quite close to their host stars, and astronomers estimate that there are around 17 billion such planets in the Milky Way.

    "These worlds are hotter than our planet, although some could be of a comparable temperature (and could, therefore, be habitable) if they are orbiting a cool star called a red dwarf.” "

    Of course, the next paragraph makes it clear this article is nonsense, and that the 100 billion number is based on a proposal to do a study to prove that number:

    "“Our proposal is to measure the number of Earth-mass planets orbiting stars at distances typically twice the Sun-Earth distance. Our planets will, therefore, be cooler than the Earth. By interpolating between the Kepler and MOA results, we should obtain a good estimate of the number of Earth-like, habitable planets in the Milky Way. We predict a number in the order of 100 billion. Of course, it will be a long way from measuring this number to actually finding inhabited planets, but it will be a step along the way.” "

  3. Earth is the best planet for mankind anyway.

    Not everything and not everywhere is for us.

    Five billion planets to be destroyed?
    It will take years for us, but we can do it.
    Yes, we can!

    What if we find a planet perfect for people, having a similar climate and even nature, but on which e. g. dinosaurs still live. Do we have the right to take it?
