Planet 13,000 Light Years Away from Earth - Ice World (Gravitational Microlensing Effect)

An interesting method called Gravitational Microlensing is capable of revealing distant worlds. In 2017, a very distant planet was discovered, located 13,000 light-years from Earth, between the constellations Scorpio and Sagittarius.

Named OGLE-2016-BLG-1195Lb, the planet is rocky like Earth and icy because it orbits a small Red Dwarf star. The gravitational lensing effect was predicted by Albert Einstein since 1915. With General Relativity Einstein demonstrated the effects of gravity, and today the technique allows us to locate small worlds, which emit little light and are very distant.

When astronomers observe a star, light waves come straight from the star to the telescope. However, if another star passes in the middle, the gravity of the nearest star acts as a natural magnifying glass...

The planet shares many characteristics with Earth, and its discovery demonstrates that rocky worlds like ours must be plentiful in our vast galaxy of hundreds of billions of stars.

Let's learn about the interesting method and get to know another amazing world of our galaxy🚀
