Join CNN’s Wonder Theory science newsletter to delve into the universe with updates on captivating discoveries, scientific progress, and more. The new year begins with the peak of the Quadrantids, one of the most powerful meteor showers annually, as per NASA. Unlike other showers that last for days, the Quadrantids’ peak is brief, lasting only about six hours, making it one of the fastest meteor showers to streak across the night sky. Meteors are remnants of shattered asteroids and comet particles that disperse in dusty trails encircling the sun. Each year, Earth traverses these debris trails, producing vivid, fiery displays known as meteor showers as the dust and rocks disintegrate in our atmosphere. The peak of the Quadrantids is notably short due to the shower’s sparse particle stream, with Earth swiftly passing through the densest concentration of particles at a perpendicular angle, according to NASA.
Observing the Quadrantids
The maximum meteor activity is anticipated to peak between 10 a.m. ET to 1 p.m. ET (15 to 18 Coordinated Universal Time) on January 3, favoring Alaska, Hawaii, and far eastern Asia, as stated by Bob Lunsford, the fireball report coordinator for the American Meteor Society. The prime time to witness the meteor shower is just before dawn, according to EarthSky. Sky-watchers on the east coast of North America may witness up to 25 meteors streaking across the skies, while those on the west coast could see double that amount due to a later sunrise, Lunsford noted. Clear skies over western Alaska might offer viewers an excess of 100 meteors per hour. The waxing crescent moon, only 11% full, will set well before midnight, providing unobstructed views of the meteor shower.
For the best viewing experience, head to an area away from bright city lights, allowing meteors to be visible every couple of minutes from late evening until dawn. Find an open space with a broad view of the sky, have a chair or blanket handy for looking straight up, and give your eyes time to adjust to the darkness for optimal meteor spotting — without distractions like your phone.
Curious Origins
The Quadrantids received their name from the constellation Quadrans Muralis, observed in 1795 but now considered obsolete and not part of the recognized modern constellations. The radiant point of the shower forms a right angle between the Big Dipper.
The brilliant star Arcturus will be a prominent feature during the upcoming Quadrantid meteor shower, as reported by EarthSky. Although Arcturus will shine brightly, the meteors themselves will grace all parts of the sky, so stargazers need not limit their gaze to a single direction.
Unlike many other meteor showers, such as the Geminids, which originate from icy comets, the Quadrantids have a more enigmatic source – a mysterious asteroid or “rock comet.” This peculiar celestial body, known as 2003 EH1, orbits the sun once every 5.52 years and spans a diameter of 2 miles (3.2 kilometers).
Additionally, astronomers suspect that another celestial entity, Comet 96P/Machholz, may also play a role in the Quadrantid meteor shower, as indicated by EarthSky. This comet completes an orbit around the sun every 5.3 years.
Scientific analysis suggests that a larger comet became trapped in a short orbit by the gravitational pull of the sun around 2000 BC. Over the course of centuries, this comet fragmented, leaving behind a trail of meteors before disintegrating sometime between 100 and 950 AD. This astronomical event resulted in the creation of numerous celestial bodies collectively referred to as the Machholz Complex. Within this complex are the parent bodies of the Quadrantid meteor shower – Comet 96P/Machholz and asteroid 2003 EH1 – along with two distinct comet groups and eight other meteor showers, as detailed by EarthSky.
Looking ahead to meteor showers in 2025, following the Quadrantids, there will be a temporary pause in meteor activity until April. Subsequently, stargazers can anticipate the following meteor showers and their peak dates:
– Lyrids: April 21-22
– Eta Aquariids: May 3-4
– Southern Delta Aquariids: July 29-30
– Alpha Capricornids: July 29-30
– Perseids: August 12-13
– Draconids: October 8-9
– Orionids: October 22-23
– Southern Taurids: November 3-4
– Northern Taurids: November 8-9
– Leonids: November 16-17
– Geminids: December 12-13
– Ursids: December 21-22
