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. (Watch in HD and increase cellphone brightness) 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🚀 Support the channel :) Together, let's bring astronomy to more and more people. Science is something the channel believes is very important to humanity.

Alpha Centauri is the closest planetary system to the solar system and stands out in our night sky. Alpha Centauri is 4.3 light-years from Earth and is actually a triple star system. Two stars orbit close together, while a third star (closest to the Sun) completes the system. (Watch in HD and increase cellphone brightness) Recently, two planets were found orbiting one of the stars, and one of them is even in the Habitable Zone. The components of the Alpha Centauri system are: Stars: Alpha Centauri A - Yellow Dwarf like the Sun Alpha Centauri B - Orange Dwarf Proxima Centauri - Red Dwarf, closest star to the Sun Planets orbiting Proxima Centauri: Next b and Next c Proxima c is a possible mini-Neptune much larger than Earth. Proxima b is in the Habitable Zone, and is about the same size as Earth and may have many similar features to our planet. We will see ways to travel to Alpha Centauri one day, learn about the method of discovering the planets, the characteristics of all the stars that make up the system, how the solar system would be seen from there, and of course, travel below the atmosphere of these fascinating neighboring worlds.

Large galaxies, such as Andromeda and the Milky Way, have small galaxies around them, called satellite galaxies. (Watch in high quality) The first satellite found in Andromeda was M32, observed in the 18th century. The satellite has great prominence around the giant galaxy and has already suffered gravitational turbulence by Andromeda (and has also caused it). Let's get to know the characteristics of these small and abundant galaxies that form the galactic clusters, travel between their stars and visit the remote past of our planet Earth. 🔭 Support the channel :) Together, let's bring astronomy and science to more and more people.

Let's get to know an unusual system that is very close to us, just a few light years away. Gliese 229 is composed of a star, two planets, and a substellar object that is neither a star nor a planet. (Watch in high quality) All the stars of the neighboring system will be visited and we will know the characteristics of each one of them 🔭. The unique system was formed by the forces of gravity and has a small star with two planets, a substellar object (or brown dwarf) and two giant planets. 🚀 Support the channel :) Together, let's bring astronomy and science to more and more people.

The Methuselah Star is a rare star surviving from an ancient stellar generation. (Watch in high quality) Methuselah's star currently inhabits our galactic neighborhood, but it has passed through several generations of stars as it orbits the galaxy. The star is billions of years old and let's get to know a little about its chemical analysis, which revealed its rare advanced age.
