Aligning Markarian’s Chain

Markarian’s Chain is a remarkable string of at least eight galaxies stretching across the boundary between the constellations Virgo and Coma Berenices. This celestial wonder spans approximately 1.5 degrees in length and is nestled within the heart of the illustrious Virgo Cluster of Galaxies.

Visible to observers using telescopes as modest as 150mm (six inches) in aperture, Markarian’s Chain offers a tantalizing opportunity to explore a diverse array of galactic forms, from majestic ellipticals to spiral showpieces and even an intriguing pair of interacting galaxies known as “The Eyes.”

In the early evening hours of April, this cosmic chain graces the eastern sky, climbing to a respectable altitude of around 50 degrees by midnight. Its location within the rich confines of the Virgo Cluster ensures a backdrop of countless additional galaxies, adding to the visual splendor and making Markarian’s Chain a true celestial treasure trove for deep-sky enthusiasts.

Anchoring the southwestern end of Markarian’s Chain are the formidable duo of Messier 84 and Messier 86, two massive elliptical galaxies that shine at 9th magnitude. These celestial giants reside just 17 arcminutes apart, nestled within the boundaries of the Virgo constellation, around 5 degrees northwest of the star rho Virginis.

For those equipped with larger telescopes in the 300mm (12-inch) range, an enticing challenge awaits nearby: the faint NGC 4387, a diminutive galaxy of 13th magnitude spanning a mere 1.7 arcminutes across. This tiny celestial gem lies just south of the imposing M84 and M86, offering a glimpse into the diverse array of galactic forms that populate Markarian’s Chain.

Continuing northward along the chain, we encounter NGC 4435 and NGC 4438, an interacting pair of galaxies collectively known as “The Eyes.” NGC 4435, the smaller of the duo, is a barred lenticular galaxy shining at magnitude 10.8, while its larger and more disrupted companion, NGC 4438, boasts a brighter magnitude of 10.0. This dynamic interplay between the two galaxies, with their distorted shapes and bursts of star formation, makes “The Eyes” a captivating target for observers.

Farther along the chain, within the boundaries of Virgo, lies NGC 4461, an 11th magnitude spiral galaxy spanning 3.7 arcminutes by 1.5 arcminutes. Accompanying it is NGC 4458, a smaller and rounder elliptical galaxy located just to the north. While NGC 4461 should be visible through a 150mm (6-inch) telescope, NGC 4458 may require the added light-gathering power of a 200mm (8-inch) instrument to fully appreciate its subtle details.
