The galaxy will be visible to the naked eye until October 3 throughout the country including the borderland between Juárez-El Paso.
🖊 Earth and Sky 📸 Space Fact
This week in Mexico we will be able to see a show that has fascinated entire generations: the andromeda galaxy will be visible in the night sky. We tell you how to see her.
The show will be available until October 3. No extra tools beyond the eyes will be needed to witness it. The Andromeda galaxy will be visible to the naked eye, without the need for binoculars or telescopes.
However, weather conditions will not be in everyone's favor: current cloud clouds in a southern region of the country will affect visibility. It is likely that inhabitants of Veracruz, Tabasco, Yucatan and Campeche will not be able to join the show.
For those who will have clear night skies it will only be necessary to be located at a point where light pollution is very low, one of the main obstacles to astronomical observation of any order.
Now, locating this galaxy isn't as easy as locating Venus, but it's perfectly possible. Looking northwest, above the constellation Aries and to the left of the constellation Pisces, we will find the constellation Andromeda. At the center of this constellation is the Mirach star.
To the left and a little upwards, the next star in the constellation is Andromedae. If you're still in the same direction, you'll find an oblong glow that's not a star: it's the Andromeda galaxy.
Another way to find Andromeda is to first locate the constellation Pegasus, which is distinguished by a central rectangle above the constellation Pisces. At the bottom of the rectangular is Alpheratz. This star is shared with the constellation Andromeda. Alpheratz represents Andromeda's face.
A few degrees to the north would be the star v Andromeda, who would come to represent part of the leg of the mythological character. Just above v Andromeda would find the galaxy we are looking for.
Capturing it with the naked eye is a huge satisfaction, because this galaxy is one of the furthest objects we can see with the naked eye.
The size of Andromeda is similar to that of the Milky Way, about 220 thousand light-years in diameter. The diameter of our galaxy is estimated at 200 thousand light-years.
It is 2.5 million light-years away from us and is expected to have merged with the Milky Way in five billion years. The resulting galaxy would be called Lactameda.
While the fusion of the two galaxies for some may sound like a catastrophe, scientists say that if that astronomical event were to happen today, we would hardly realize it in our daily lives. For a fusion of galaxies does not involve the collision of the stars and planets that make up it.
