Can you find the North Star? (Hint: it's the 48th brightest star in the night sky.) What about finding & nbsp; South? & Nbsp; The vernal vernal equinox (or spring) sees the beginning of astronomical spring, which is one of the easiest times of the year to learn how to navigate using the sky. Not just to find north and south, but also east and west.

Our "magnetoreception" skills

Learn to navigate with the help of bright stars visible cities and you will quickly develop an innate sense of direction. This may seem unlikely, but the geoscientists and neurobiologists at Caltech and the University of Tokyo now have irrefutable evidence of an ancient magnetic sense in humans. A study published today recorded the brain activity of adults during magnetic field manipulations, and the results suggest that the human brain may react unconsciously to changes in magnetic fields of the Earth.

Such "magnetoreception" skills are common among migratory birds and sea turtles, which have a geomagnetic sense that supports a biological navigation system. Experience has shown a decrease in brain alpha band activity in some participants who, according to the researchers, were tuned to the magnetic field of the northern hemisphere, where the study was conducted.

How to read shapes in nature

This sense of direction can be cultivated simply by going outside and paying attention to forms. "All forms of nature make sense," says Tristan Gooley, author of The instinct of nature and publisher of The natural navigator. "The wildflowers may not interest you, but you will notice that all the flowers are facing south, and there is a relationship between their origin and the stars that you will see later in the sky," he says. Gooley believes that every form of nature has meaning, and when you understand them, and how they help you navigate, read the weather or indicate the time of day, your brain starts to solve problems without that you have to think. about that. "This is indeed our sixth sense," he says, though it is not pseudoscience, and it is an observation of navigational stars.

How to navigate using the night sky

This sixth sense is dormant in many people, but there is no easier way to wake up your old sensory system by learning to navigate the night sky, especially in the spring. Do it and it is very easy to quickly develop an instant sense of the direction you are facing without thinking about it. This "blanket of stars?" There is no cover. The night sky can be traveled and known. Here's how to do it.

How to say that it's spring looking at the stars

What happens in the night sky tells you the time of year, but only if you observe the stars at the same time of the day. There are two important stars that rise to the east in the darkness in the spring; Arcturus supergiant red in the constellation Bootes and the double star Spica in Virgo. The memory aid "Arc at Arcturus, Spike at Spica" help here; you follow the & quot; tail & # 39; from the Plow / Big Dipper in the northeast sky to the east, then head to Arcturus, then go straight to Spica, which is just above the horizon is before midnight in March. Both are bright stars, so easy to find.

You will never lose them again (until they become "day" stars in September).

How to find north of the northern hemisphere

For those in the northern hemisphere, it is simply to find Polaris, the North Star, located directly above the North Pole. Since the axis points of the Earth seem to point directly to it, Polaris never seems to move, only to turn. Locate the Big Dipper / Plow in the northern sky, find the two stars at the end of its bowl (Merak and Dubhe), draw a line through and continue for about four times the distance that separates you from the reasonably bright star alone. That's Polaris, the 48th brightest star in the sky. It is always above the north, and its height above the horizon indicates your latitude – your distance from the equator (at the equator, you can not see the Polaris, and at the North Pole, it is just above your head).

For those in the southern hemisphere, the best way to find the north in spring is to look for Orion (see How to navigate with Orion, below).

How to find East and West

Equinox means "equal night," so whether you're in the northern hemisphere or the southern hemisphere, the sun will rise full east, will follow a circular arc along the celestial equator and will He was sleeping west on March 20th. The same goes for the autumn equinox, which then occurs on September 23, 2019. So, all you have to do is watch a sunrise and sunset in March and September and you will know exactly where these cardinal points are in any environment.

How to navigate with Orion

The constellation Orion rises up and goes down in the same way. "Orion rises to the east and sets to the west, and when he is the tallest in the sky, his sword hangs," says Gooley. "But the quickest way to remember is that if you see Orion somewhere near the horizon, you look to the east or the west." However, it is seasonal. "From May to August, you will not see Orion at all."

How to navigate using the moon

"Like all celestial objects, the moon rises to the east and sets to the west so you can use the moon as a perfect compass," says Gooley. "For navigation, the full moon is great because you do not have a single dark minute during the night," he says. This is because a full moon rises at sunset and sets at or near sunrise. "If you want to see clearly on the outside and see a lot of details, keep the sun on your back and the moon on your forehead." Crucially, a full moon is still roughly south in the middle of the night, as shown in the northern hemisphere. , or north seen from the southern hemisphere.

After a few months of sailing by stars, it becomes second nature and you even stop watching the stars themselves because you know where they are going to be at any time of the year.

Can you find the North Star? (Hint: it's the 48th brightest star in the night sky.) Why not find the south? The spring (or spring) equinox of Wednesday marks the beginning of the astronomical spring, which is one of the easiest periods of the year to learn how to navigate with the help of the sky . Not just to find north and south, but also east and west.
