NASA astronomers said they’ve discovered a planet that they believe has a 100% chance of having life on it

NASA astronomers said they’ve discovered a planet that they believe has a 100% chance of having life on it and its relatively close to us, just in our cosmic neighborhood — meet Gliese 581d.

Gliese 581 is a red dwarf star located about 20 light-years away from Earth in the constellation Libra — One light-year is about 6 trillion miles (10 trillion km); Out of the billions of stars in the sky, Gliese 581 is the 89th closest known star to the Sun.

In 2005, astronomers found six exoplanets orbiting their star in nearly circular paths and they were named as Gliese b, c, d, f and g; they used the indirect method to found these planets, which mean that the planets cannot be viewed with a telescope; Astronomers used radial velocity data on the star. This method looks at a star’s tiny movements due to the gravitational tug from orbiting bodies. The subtle tugs let researchers estimate the planet’s mass and how long it takes to circle its star.

It was calculated that Gliese 581d is in the perfect not-too-hot not-too-cold Goldilocks zone, just the ideal distance away from the start to be able to support life; in fact, some astronomers are 100% certain that they do:

Personally, given the ubiquity and propensity of life to flourish wherever it can, I would say, my own personal feeling is that the chances of life on this planet are 100 percent,

said Steven Vogt, a professor of astronomy and astrophysics at the University of California, Santa Cruz.

I have almost no doubt about it.
