How many intelligent alien civilizations are out there among the hundreds of billions of stars in the spiral arms of the Milky Way?

The Milky Way is full of habitable real estate, with roughly half of all sunlike stars hosting Earth-size worlds that could be friendly to life.

More than 300 million worlds with similar conditions to Earth are scattered throughout the Milky Way galaxy. A new analysis concludes that roughly half of the galaxy’s sunlike stars host rocky worlds in habitable zones where liquid water could pool or flow over the planets’ surfaces.
