M87 (Virgo A) Complete Guide — Elliptical Galaxy in Virgo

Overview

Virgo A (M87) is a giant elliptical galaxy in Virgo, catalogued as NGC 4486. At magnitude 8.6 and roughly 60 million light-years away, it is one of the brightest Virgo Cluster members — and one of the most scientifically significant galaxies in the entire sky. In 2019, the Event Horizon Telescope produced the first image of a black hole shadow at M87's core.

Elliptical galaxies are dominated by old stellar populations with minimal ongoing star formation. M87 hosts one of the most massive black holes known, feeding a relativistic jet detectable at radio and optical wavelengths.

Basic Data

Physical Characteristics

M87 lies about 60 million light-years away and glows at magnitude 8.6 — the brightest purely elliptical galaxy in Messier's catalog. Its massive size and active nucleus have made it a cornerstone of extragalactic astronomy.

Observing Guide

Finding It

M87 is located in the heart of the Virgo Cluster, transiting around 8–10 PM in spring. From Epsilon Virginis (Vindemiatrix), move west into the dense galaxy field. A star chart helps navigate the crowded Virgo Cluster; M87's bright, rounded glow stands out once you're in the right area.

Observing Tips

Even a small telescope shows M87 as a soft, round glow. Dark skies and full dark-adaptation let you trace its extended halo. Use low magnification — the galaxy's diffuse outer envelope disappears at high power. Seeing the inner jet requires very large aperture under exceptional conditions.

Recommended Equipment

An 80mm or larger refractor or reflector is sufficient to detect M87 on a dark night. Larger instruments reveal the brightness gradient from core to outer halo more clearly.

Astrophotography Tips

M87 is a rewarding astrophotography target — its near-perfect circular symmetry makes it immediately recognizable. Track with an Equatorial mount, use moderate-to-high ISO, and stack long exposures to capture the extended halo. Deep imaging can also reveal the optical jet emerging from the nucleus.

Summary

M87 is the dominant elliptical galaxy of the Virgo Cluster and one of the most celebrated objects in modern astronomy. Visually it requires a telescope and dark skies to appreciate fully; photographically it reveals a luminous, ancient giant whose supermassive black hole has reshaped our understanding of galaxy evolution.
