Open your eyes par. From April 16 until April 30, one of the oldest rains of spring fleeting stars that caught our attention is to cross the northern hemisphere of the planet. This phenomenon occurs every year since mid -April.
The lyed are one of the oldest meteorit rains known since they were observed in 687 a. C. AD in China, more than 2,700 years ago. When they cross the atmosphere of the Earth, they do not tend to leave behind long gusts of incandescent dust, but they can occasionally produce a flash of significant light.
Up to 18 meteors to be seen per hour
NASA, an American space agency, reports that the intensity of the lyed should be at its peak on the night of Monday, April 21 to Tuesday, April 22: This means that 18 meteors can be observed per hour in the sky.
This peak of intensity will take place in a period of decrease in the moon, that is, that the sky must be particularly dark. The croissant of this earth’s satellite is full of 27% in this period, there is something to expect to see some fleeting stars in the sky.
To wait to see this rain of fleeting stars, it is recommended to look for a place where Light pollution It is weak, even absent. In spite of this, the moon can alter the visibility of the meteors, which will be full on April 24, only a few days after the peak in the intensity of the lyed.
Compets debris
Once dark, place the nose out of the air and the feet oriented towards the east. You should know that these meteorites appear near the constellation of the lyre: the latter is towards the star of Vega, one of the brightest points in the sky.
It is possible to locate them thanks to the telephone applications that allow, pointing the device’s camera to the sky, reveal the name of the heavenly objects.
The lyed are called fleeting stars, but in reality they are comet’s debris. In fact, every year in his career around the sun, the earth crosses the dust left by comet C/1861 G1 Thatcher. But when they cross the atmosphere, they undergo friction and eventually enter combustion and, therefore, leave a light drag in the night sky.
