In late April (Early May), as Earth passes through the comet debris trails from the most well-known object in astronomical history, 𝐇𝐚𝐥𝐥𝐞𝐲'𝐬 𝐂𝐨𝐦𝐞𝐭. The 𝐄𝐭𝐚 𝐀𝐪𝐮𝐚𝐫𝐢𝐢𝐝 𝐌𝐞𝐭𝐞𝐨𝐫 𝐒𝐡𝐨𝐰𝐞𝐫𝐬 are produced when Earth passes through these trails of debris. This year's peak will occur on 𝐌𝐚𝐲 𝟓-𝟔, 𝟐𝟎𝟐𝟔. It is called the Eta Aquariid Meteor Shower because it radiates out from near the star 𝐄𝐭𝐚 𝐀𝐪𝐮𝐚𝐫𝐢𝐢 in the constellation Aquarius. The fast and bright meteors have speeds of about 𝟔𝟔 𝐤𝐦/𝐬𝐞𝐜.They are some of the fastest meteors visible annually and produce large glowing trains after the meteors burn up in the atmosphere. The significance of the Eta Aquariid Meteor Shower is not only due to the high speed of the meteors but also because every streak of light seen during the showers represents fragments of Halley's Comet. As such, Halley's Comet is believed to be the source of dozens of recorded returns around the Sun. Its first documented records were from ancient Greece in 240 B.C., and its last visit to our solar system occurred in 1986.
For observers in the Philippines and other low-latitude regions, the Eta Aquariids offer a distinct advantage. Because the shower's radiant point rises higher above the horizon in the southern sky, countries near the equator including the Philippines experience 𝐬𝐢𝐠𝐧𝐢𝐟𝐢𝐜𝐚𝐧𝐭𝐥𝐲 𝐛𝐞𝐭𝐭𝐞𝐫 𝐯𝐢𝐞𝐰𝐢𝐧𝐠 𝐜𝐨𝐧𝐝𝐢𝐭𝐢𝐨𝐧𝐬 than those in higher northern latitudes. According to 𝐍𝐀𝐒𝐀 and 𝐄𝐚𝐫𝐭𝐡𝐒𝐤𝐲, the best time to observe the shower is during the 𝐩𝐫𝐞-𝐝𝐚𝐰𝐧 𝐡𝐨𝐮𝐫𝐬 𝐨𝐟 𝐌𝐚𝐲 𝟔, when the radiant is highest in the southeastern sky. Under dark, clear skies, observers in the Philippines may see up to 𝟒𝟎–𝟓𝟎 𝐦𝐞𝐭𝐞𝐨𝐫𝐬 𝐩𝐞𝐫 𝐡𝐨𝐮𝐫 at peak. However, for observers in urban areas such as Cebu City, light pollution will significantly reduce visible rates, making a dark, open location away from city lights essential for the best viewing experience. No telescope or special equipment is required for viewing the Eta Aquariid Meteor Shower only a dark location, patience, and a clear view of the sky toward the southeast.
Beyond the display itself, there are many scientific elements of the meteor shower that make connections to our known world and beyond. It has been determined by astronomers that 𝐇𝐚𝐥𝐥𝐞𝐲'𝐬 𝐂𝐨𝐦𝐞𝐭 is a 𝐩𝐞𝐫𝐢𝐨𝐝𝐢𝐜 𝐜𝐨𝐦𝐞𝐭 which orbits the sun in approximately 75-76 year cycles. Therefore, like all other celestial bodies (such as Earth's moon) or satellites (Philippine Space Agency's 𝐃𝐢𝐰𝐚𝐭𝐚 & 𝐌𝐚𝐲𝐚), Halley's Comet follows an elliptically shaped orbital path. It is the heat from the sun that causes the nucleus of Halley's Comet to lose gas and dust when the comet approaches the sun, and thus creates a stream of dust and gas along its orbital path. Each year when Earth passes through this stream of dust and gas, the very small particles (grain size) entering Earth's atmosphere at high velocities create heat in their surroundings causing them to glow and become visible as the bright streaks of light called "𝐦𝐞𝐭𝐞𝐨𝐫 𝐬𝐡𝐨𝐰𝐞𝐫𝐬" that we see each year as the Eta Aquariid Meteor Shower.
The 𝐏𝐀𝐆𝐀𝐒𝐀 𝐀𝐬𝐭𝐫𝐨𝐧𝐨𝐦𝐲 𝐃𝐢𝐯𝐢𝐬𝐢𝐨𝐧 provides updated sky observation guides for Filipino observers, the 𝐏𝐡𝐢𝐥𝐢𝐩𝐩𝐢𝐧𝐞 𝐒𝐩𝐚𝐜𝐞 𝐀𝐠𝐞𝐧𝐜𝐲 (𝐏𝐡𝐢𝐥𝐒𝐀) continues to advance the country's capacity to study and participate in space science at every level. The Eta Aquariids serve as a reminder that some of the most remarkable phenomena in astronomy require nothing more than a dark sky and a willingness to look. Given the Philippines' equatorial position, 𝐌𝐚𝐲 𝟓-𝟔 marked a night worth remembering for local skywatchers. The debris of a comet with dozens of recorded solar returns crossed our atmosphere in seconds and for those who watched, it was extraordinary.
