03 EARTH LIKE "PLANETS" WHERE LIFE CAN EXIST
Discovering the first true "ALIEN EARTH" is a long-held dream of astronomers — and recent exoplanet discoveries suggest that their dream will come true in the not-too-distant future.
Scientists have found nearly 2,000 alien planets since the first such world was confirmed orbiting a sunlike star in 1995. More than half of these discoveries were made by NASA's Kepler space telescope, which launched in 2009 on a mission to determine how common Earth-like planets are throughout the Milky Way galaxy.
Kepler's observations have shown that small, rocky worlds like our own are abundant in the galaxy, and some of them may be capable of hosting life as we know it.

1) Gliese 667Cc:
This exoplanet, which lies just 22 light-years from Earth, is at least 4.5 times as massive as Earth, and researchers aren't sure whether or not it's rocky. Gliese 667Cc completes one orbit around its host star in a mere 28 days, but that star is a red dwarf considerably cooler than the sun, so the exoplanet is thought to lie in the habitable zone.
However, Gliese 667Cc — which was discovered with the European Southern Observatory's 3.6-meter telescope in Chile — may orbit close enough in to be baked by flares from the red dwarf.

2) Kepler-22b:
Kepler-22b lies 600 light-years away. It was the first Kepler planet found in the habitable zone of its parent star, but the world is considerably larger than Earth — about 2.4 times our planet's size. It's unclear if this "super-Earth" planet is rocky, liquid or gaseous. Its orbit is about 290 days long.

3) Proxima b:
The closest alien planet to our solar system is even more Earth-like than scientists had thought, new observations suggest.
In a new study, an international team of researchers found that the minimum possible mass for Proxima b, which lies just 4.2 light-years from Earth, is just 17% more massive than our planet.
Previously, scientists thought that this exoplanet, which lies in the habitable zone of its star, harbored a minimum of about 1.3 Earth masses. The new measurement indicates that Proxima b could be even more like our home planet, at least in size, than previous observations led scientists to think.

"Allah is the one who created seven heavens and from Earth like them (of the corresponding type); [Allah’s] command descends among them (heavens and earth) so that you may know that Allah is capable of anything and that Allah knows everything".

"Did you see how God created seven heavens one above another and made the moon a light therein and made the sun a lamp".

"(God) is the One who has set out for you the stars, that you may guide yourselves by them through the darkness of the land and of the sea. We have detailed the signs for people who know."
