This will be the last shower of the stars of the year and will be visible on almost the entire American continent.
It's about gemínidas, one of the biggest rains of this type that appears every year, and this can be seen briefly both to the north and to the south of the planet.
Although it is called the "star" shower, it is actually a meteor that burns when it enters the earth's atmosphere.
In the case of the geinids, baptized on the constellation "Gemini", in which they are visible, they are particularly bright and fast management, except that they tend to look yellow
They have a maximum concentration each year in December and this year their decline is from 7 to 17 days, the first hours of the 13th and 14th.
The National Aeronautics and Space Administration (NASA) considers them one of the best and most visible meteorologists seen on Earth.
But some time ago they were not.
"The gums begin to appear in the middle of the nineteenth century, but the first rains are not so remarkable, with only 10 to 20 meteors seen per hour," NASA explains.
"Since then, precious stones have become one of the most important rains of the year. You can see 120 meteors per hour in ideal conditions"he adds.
How do you see them?
Places far from cities are the best way to observe this and every shower of the stars.
In case of germinides on Thursday and Friday, NASA recommends wait for the moon to be set, because its light makes almost invisible the smallest meteors that are the most numerous.
Find the darkest place you can Give your eyes about 30 minutes to adapt to the darkness. Avoid watching your mobile phone as it will ruin your night vision, "says the recommendation.
The best thing is to find a comfortable place to lie down and look at the sky attention and patience.
The largest number of gemmids is expected in the early morning hours around 02:00 when it usually has up to 100 meteors per hour.
However, NASA shows it is common to see between 30 or 40 meteors per minute in places with appropriate conditions such as a cloudless field away from urban centers.
"The clear, dark sky is the most important ingredient in the observation of meteor showers."
This year there will be another gift as there will be a small "ghostly" green light in the constellation Taurus, which will be Comet 46P / Wirtanen which is approaching the Earth.
His strange background
The earth passes every year along the road full of debris thrown "from strange and rocky objects," called 3200 Phaeton, NASA explains.
Dust and sand burn when they enter the atmosphere of the Earth that is visually visible wave of "shooting stars".
Although this is clear to scientists, it is not the origin of the carriage,
It is described as an asteroid near the Earth or as a missing comet.
"There is another object, an Apollo asteroid called 2005 UD, which is in orbit, dynamically similar to Phaethon, which generates that both are part of a larger body that has separated or collided with another asteroid"NASA explains on its website.
Gemini can be the remnants of this long-standing collision event, detailed space agency experts.
