Eta Aquáridas was recorded this morning by the Monte Castelo observation station in Santa Catarina, considered one of the most beautiful meteor showers of the year. Maximum activity for this annual event is expected on Friday (6), when up to 20 meteors can be observed per hour – And Brazil has a distinct point of view.
Eta Aquarids are so named because meteorites converge in the constellation Aquarius, with the remnants of the famous Halley’s Comet. This meteorite occurs annually between April 19 and May 28, when Earth crosses the comet’s orbit where a series of debris left over millions of years has floated. When they enter the atmosphere, they leave a harmless luminous trace.
The planet passes through the path of the comet twice a year, at two different points, and is also responsible for Orionidas, in the constellation Orion, which occurs in the month of October each year.
Eta aquarides were first associated with Halley’s Comet in 1876 by British astronomer Alexander Stewart Herschel. In 1947, in the United Kingdom, the Jodrell Bank Observatory radio telescope detected this event for the first time in the radio range of the electromagnetic spectrum.
Halley is the only comet visible with the naked eye and passes through the Earth’s region of the Solar System every 74 to 79 years. The last time it could be seen was in 1986, and its return is scheduled for 2061.
