Full Moon Challenges Lyrid Meteor Shower Spectacle in Washington

6

As Washington anticipates the onset of the annual Lyrid meteor shower, stargazers may find their celestial spectatorship somewhat hindered this year. The meteoric spectacle is due to reach its zenith in tandem with a nearly full moon, rendering some of the scarcity of the brighter meteors.

Every year in mid to late April, the heavens play host to the Lyrids, a meteor shower associated with the comet Thatcher. The metropolitan skies above Washington are set to be illuminated, with the peak activity predicted for Sunday into Monday. Depending upon the clarity of the skies, expect to see a modest display, with 10 to 20 meteors streaking across the canvas of the night per hour.

The Lyrids meteor shower, along with several others throughout the year, are the residuals of comets and do not require any specialized equipment to be seen. When debris from these comets penetrates Earth’s atmosphere, the fierce resistance from the air causes them to heat up exponentially. This fiercely incandescent heat causes the air to light up and a flaming tail – the hallmark of a shooting star – can be seen for a fleeting moment.

These ephemeral ribbons of incandescent light, enveloping the swiftly moving celestial debris, and ranging in size from a mere dust particle to the size of a boulder, create a captivating phenomenon in the nocturnal sky. The optimal time for viewing meteor showers typically falls within the midnight to pre-dawn window, the cosmic performance shining at its brightest under the cloak of pitch-black skies, well away from the glare of bustling city lights, and under cloudless conditions when the moon is at its faintest.

“Uninterruptedly gaze into the northeastern sky to experience the visual grandeur of the Lyrids,” commented Don Pollacco, an astronomer at the University of Warwick. “It’s an awe-inspiring sight to behold these celestial wonders”.

The Northern Hemisphere offers the most unimpeded view of the Lyrids, albeit the moon’s glare might disrupt the spectacle somewhat, as per the guidelines from the American Meteor Society. Under ideal circumstances, “the meteors tend to blaze brightly, leaving behind a glowing bluish trail that lingers in the sky for a few moments”, said Pollacco.

As for the next celestial presentation, turn to the American Meteor Society for the most contemporary and comprehensive list of forthcoming large meteor showers with details on peak viewing days and the moonlight conditions. The first week of May will witness the Eta Aquarids meteor shower. This stellar spectacle, resulting from the debris of Halley’s comet, will be best seen in the Southern Hemisphere.
