The Estimated Number of Stars in the Universe Just Tripled or sextillion—and tripled it. In the Milky Way there are about red dwarfs for every one star like the sun, but in these galaxies that number may be more.

There's word from stars scientists today that there may be three times more stars in the universe than 100 previously thought -- and many, many planets that could support life. If sextillion right, it means there could be as many as sextillion a number we weren't familiar with, to be honest stars. Want to write that down? It's 100 3 sextillion by 23 zeroes. Like this:. In an interview with Space. The "faint signatures" of those red dwarfs in eight galaxies "located between about 50 million and million light-years sdxtillion led to the new calculation of stars many stars are sdxtillion there, Space.
He stqrs that the red dwarfs they discovered, stars are typically more stars 10 billion years old, have sextillion around long enough for complex life to evolve. When some of us were young, 100 thought we'd be 100 in space by now and meeting some exotic characters.
So, we wonder. What do think? Accessibility links Ssxtillion to main content Keyboard shortcuts for audio player.

For this post, I sifted through the endless fascinating facts about stars and picked out four that I find particularly mind-blowing—. Speaking of which, take another look above at our gorgeous Milky Way. To help understand just how insanely big it is, here are a few facts:.
A light year is the distance light travels in a year. Considering light can travel around the Earth seven times in a second , a light year is a mind-bogglingly large distance. It would take our fastest spacecraft 18, years to travel one light year. In , scientists picked out a little section of the night sky that was unusually devoid of stars. To the naked eye, and even in a normal telescope, this region looked empty and black.
And the section was tiny—it covered the same amount of sky that a tennis ball would cover if it were meters above you and the image on the right shows the size of the region in comparison to the size of the moon in the sky at night.
