The ETA acuáridas are a meteor rain, also known as the rain of stars, directly associated with Halley comet, A large and brilliant light blue body that orbits around the sun every 76 years and that is currently one of the best known natural objects internationally for its luminosity.
This rain of stars is visible in the territory of the United States approximately from April 30 to May 20 of each year and, according to the National Aeronautics and Space Administration (POTfor its acronym in English), its greatest activity in 2025 possibly registered next Tuesday, May 6.
Given this situation, the meteor rain is less than 24 hours after possibly reaching its highest peak, so NASA reported that the American population will have to get up “very early” to be able to observe this heavenly show, considered one of the most important events of spring in the United States.
The ETA Aquáridas rainy is also considered one of the best annual rains throughout the northern hemisphere, since it marks the end of these astronomical phenomena until July 31. According to the specialized site in the night sky and planet Earth, Earthsky, the best time to observe it is at dawn.
When and how to see the rain of stars ETA acuáridas?
In accordance with the provisions of the American Society of Meteors (AMS, in English), a non -profit scientific organization that focuses on the research and study of fleeting stars, on Tuesday, May 6 “there will be dark skies for optimal visualization” in any United States hourly zone.
AMS experts say that, regardless of the time zone, anyone who observes heaven in US territory between 2.00 and 4.00 hours in the morning “can expect to see between 15 and 20 meteors per hour.” While, in the southern hemisphere of the earth, approximately 10 per hour can be observed.

“The rain of stars ETA acuáridas produces fast meteors with visible steles and persistent that extend behind them and can last several seconds after they pass through the sky. However, surely there will be very few Bright fire balls“added the American Society of Meteors in social networks.
It is worth mentioning that one of the main tips by experts is that, if the person lives in an area Urban And he wants to observe the ETA acuáridas, it is recommended to lead to a place away from the light pollution. “The darker the sky is, the more likely there are many more meteors,” they added.
As mentioned earlier, the ETA Acuárida meteor rain has its origin in the Halley kite, because the earth crosses the path of this celestial body every spring, usually at the end of April and early May. This causes the “little ones” Rocks that detach themselves from the kite impact the atmosphere of the planet.
This phenomenon where the particles create a dazzling meteor show, if observed from the earth, will also be repeated in October and gives rise to the meteor rain of the Orionaids. However, Comet Halley – lastly in the night sky in 1986– It will not return to 2061when you complete your whole orbit.
