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.
