NASHVILLE, TN – The spring and summer meteor shower season begins this month with the Lyrid meteor shower, which runs from April 16 to April 25, but peaks on Sunday, April 22, but the Observers can also see them in the days before and after. peak.
At its peak, the Lyrids will produce between 15 and 20 meteors per hour, and the best time to see the show is early in the morning before sunrise on April 22. The moon will be out of the way and will have settled before the Lyrids start, then, depending on weather conditions in Tennessee, this show should be a winner.
Lyrids are known to be fickle and unpredictable, but typically produce between 15 and 20 meteors per hour, many with traces that last a few seconds and, occasionally, some fireballs. In some years, the rain intensifies in what is called a "rapture" and produces up to 100 shooting stars.
The last Lyrid outburst was in 1982, according to Earthsky.org, which said that the observers of the US sky. UU They were received with a spectacular show that year.
And although the calendar might suggest that another one is waiting for us – Lyrid bursts may occur they generally occur at 30-year intervals – NASA meteorologist Bill Cooke predicts an average show this year.
"People say there is a certain periodicity there," Cooke told Space.com, "but the data does not support it."
One of the oldest recorded rains, the Lyrids were detected in China around 687 BC, but their source, Comet C / 1861 G1 Thatcher, was not discovered until 1861. The meteor shower originates in the constellation of Lyra to the northeast of Vega, one of the brightest stars visible in the night sky at this time of year, but the meteors will be visible from anywhere in the sky.
All meteor showers occur when the Earth crosses the path of a comet and collides with the trail of comet debris, making its occurrence predictable. They leave bright stripes, called shooting stars.
Lyrid's meteors are fast, but not as fast as the Leonids, which arrive in November, Cooke told Space.com.
"The Leonids hit us head on," he said, while "The Lyrids are more like hitting the left front of the fender."
This is what is to come during the spring and summer:
May 6-7: The Eta Aquarids meteor shower, which runs from April 19 to May 28, is a showerhead superior to the average that can produce up to 60 meteors per hour at its peak. It favors the Southern Hemisphere, but still should be a good show in the northern hemisphere with about 30 meteors per hour. A gibbous waning moon will be problematic, blocking the weakest of the meteors. They radiate from the constellation of Aquarius, but they are visible from anywhere in the sky.
July 28-29: The meteor shower Delta Aquáridos, produced by remains left by comets Marsden and Kracht, extends from July 12-August. 23. It's an average show, producing around 20 meteors per hour at its peak, but an almost full moon will be problematic. Meteors radiate from the constellation of Aquarius, but can be seen from any location in the sky. The best viewing times are after midnight.
Aug. 12-13: The annual Perseid meteor shower, which runs from July 17 to August 1. 24, is typically one of the best of the year, producing 60 to 100 meteors per hour at its peak. Meteors are historically bright, and this should be a great year for sky watchers, since a thin crescent moon should create dark skies. The Perseids are produced by the comet Swift-Tuttle, discovered in 1862. The meteors fall between the constellations Perseus and Cassiopeia, but only look up and you can see them from anywhere in the sky.
