Virgo—Latin for “maiden” or “virgin”—is one of the largest constellations in the night sky, yet it can be surprisingly difficult to recognize. It covers more sky than any other zodiac constellation and is second in size only to Hydra, but most of its stars are relatively inconspicuous. The exception is Spica, a brilliant blue-white star that provides an easy anchor for finding the constellation.
Virgo becomes even more remarkable when you look beyond those foreground stars. The same broad region of sky contains the Virgo Cluster, an enormous concentration of distant galaxies tens of millions of light-years away. Virgo therefore takes us from stars in our own Milky Way to an entirely different scale of the universe lying far beyond them.
Arc to Arcturus, Then Spike to Spica
Virgo can be seen from most inhabited parts of the world, from roughly 80° north to 80° south latitude. In the Northern Hemisphere, it is best seen during spring, with April and May particularly good months for viewing it in the evening. In the Southern Hemisphere, the same months correspond to autumn, when Virgo is also well placed for evening viewing. Because Virgo is so large and most of its stars are relatively faint, trying to recognize the entire Maiden at once isn’t the easiest way to find it. The best place to begin is with Spica.
One of the simplest routes starts with the Big Dipper, or Plough. Follow the curve of its handle away from the bowl and you’ll reach the bright orange star Arcturus in Boötes. Keep following that curve across the sky and you’ll eventually reach Spica.
Once you’ve found Spica, you’ve found Virgo’s brightest star and a reliable anchor for exploring the much larger constellation around it. Virgo stretches across a broad region of sky, with Leo to its west and Libra to its east. Its relatively faint stars, however, mean that the outline of the Maiden is much less obvious than the enormous area it covers might suggest.
Spica Helps Navigate the Spring Sky
Spica is also a useful landmark for navigating the wider spring sky. Together with Arcturus in Boötes and Denebola in Leo, it forms a version of the Spring Triangle, a huge seasonal asterism spanning three constellations.
Add Cor Caroli in Canes Venatici and the triangle expands into the Great Diamond, sometimes called the Diamond of Virgo. Its four bright stars provide reference points for Virgo, Boötes, Leo and Canes Venatici across an enormous area of the spring sky. The Great Diamond is also a useful framework for the galaxy-rich region around northern Virgo: inside this naked-eye pattern lies a part of the sky crowded with galaxies tens of millions of light-years beyond the stars used to trace it.
Virgo Is the Zodiac’s Largest Constellation
Virgo covers about 1,294 square degrees, or just over 3 percent of the entire celestial sphere. That makes it the second-largest of all 88 constellations, behind only Hydra, and the largest of the 12 traditional zodiac constellations. Its enormous size helps explain why finding Spica is much easier than trying to recognize Virgo as a single compact star pattern.
The Sun also spends longer passing through Virgo than through any other zodiac constellation. As it follows the ecliptic—its apparent path against the background stars—it takes roughly 44 days to cross Virgo’s modern boundaries, compared with only about a week in Scorpius, the zodiac constellation it crosses most quickly.
Virgo’s Brightest Star Is Actually Two Stars
Spica (Alpha Virginis) is by far the brightest star in Virgo and about the 15th-brightest star in the night sky. Around 250 light-years away, it appears as a conspicuous blue-white point of light, standing out sharply from Virgo’s much fainter surrounding stars.
But Spica isn’t one star. It is a close binary system containing two hot, massive stars that orbit each other in only about four days. The pair is so tightly packed that even through a telescope they appear as a single point of light, and astronomers instead detect the two stars through changes in their combined spectrum. They orbit so close together that their mutual gravity even distorts their shapes, pulling them away from perfect spheres.
Spica’s name comes from Latin for an “ear of grain”, referring to the grain traditionally shown in the Maiden’s hand. That may initially seem like a curious name for a star, but it preserves an important clue to Virgo’s ancient identity—one that appears again elsewhere in the constellation.
Five Stars Help Trace Virgo’s Sprawling Shape
Spica dominates Virgo, but several of its other principal stars help trace the constellation’s sprawling outline. Five—Vindemiatrix, Auva, Porrima, Zaniah and Zavijava—form a broad pattern sometimes called the Bowl of Virgo, giving observers another useful framework for recognizing the constellation.
- Spica (Alpha Virginis) — Virgo’s brightest star, a blue-white point of light that is actually a pair of massive stars locked in a remarkably tight orbit.
- Porrima (Gamma Virginis) — One of Virgo’s most interesting double stars, about 38 light-years away. It consists of two similar F-type main-sequence stars, both somewhat hotter and whiter than the Sun, orbiting their common center of mass. Unlike the extremely tight pair making up Spica, Porrima’s two stars can be resolved through a telescope when their changing orbital separation makes conditions favorable.
- Vindemiatrix (Epsilon Virginis) — A yellow giant roughly 100 light-years away. Its name means the “grape gatherer” or “vintager,” reflecting an ancient association between its appearance in the morning sky and the grape harvest. Along with Spica’s “ear of grain,” the name preserves another clue to Virgo’s agricultural identity.
- Auva (Delta Virginis) — A red giant and one of the brighter stars forming the Bowl of Virgo.
- Zavijava (Beta Virginis) — A relatively nearby star and another of the stars outlining the Bowl.
- Zaniah (Eta Virginis) — Another Bowl member that appears as a single star to the naked eye but is actually a multiple-star system.
- Heze (Zeta Virginis) — A white main-sequence star outside the Bowl that helps complete Virgo’s broader stellar figure.
The stars may appear to form a single pattern in our sky, but they lie at very different distances from Earth and aren’t physically grouped together in space.
Virgo Is a Gateway to Thousands of Galaxies
The stars we’ve used to trace Virgo all belong to our own Milky Way. Look much farther beyond them in the same direction, however, and the scale changes dramatically. Roughly 50–55 million light-years away lies the Virgo Cluster, the nearest large cluster of galaxies to our Local Group and home to around 2,000 galaxies.
Despite the shared name, Virgo the constellation and the Virgo Cluster are very different things. The constellation is an area of sky as seen from Earth, so objects appearing within its boundaries can lie at completely different distances. The Virgo Cluster, by contrast, is a real physical grouping of galaxies occupying the same region of space.
This concentration of galaxies makes Virgo extraordinarily rich in deep-sky objects. Virgo’s boundaries contain 11 Messier objects, including galaxies such as M49, M60, M84, M86, M87 and M90. Many of the Virgo Cluster’s most prominent galaxies can be found in the broad region between Vindemiatrix in Virgo and Denebola in Leo, bringing us back to the spring-sky geography outlined by the Great Diamond.
Within this galaxy-rich region lies Markarian’s Chain, a striking line of galaxies seen against the much larger Virgo Cluster. It isn’t a separate galaxy cluster of its own. Major Virgo Cluster members such as M84 and M86 form part of the pattern, with several other galaxies continuing the chain across the sky. Through a telescope, they appear as a succession of faint, hazy patches—but each patch is an entire galaxy containing vast numbers of stars, seen from tens of millions of light-years away.
Farther south lies M104, the Sombrero Galaxy, one of Virgo’s most distinctive deep-sky objects. About 28 million light-years away, it is famous for the dark lane of dust cutting across its brilliant central bulge, giving the galaxy the appearance of a broad-brimmed hat. The Sombrero lies far to the south of the dense concentration of Virgo Cluster galaxies around Markarian’s Chain, showing how widely Virgo’s deep-sky highlights are scattered across the constellation.
You can explore these and other targets in our guide to deep-sky objects in Virgo.
M87 Galaxy Gave Us the First Image of a Black Hole
One member of the Virgo Cluster deserves a closer look: Messier 87 (M87). This giant elliptical is one of the cluster’s dominant galaxies and is enormous even by galactic standards, containing several trillion stars and around 15,000 globular clusters. Unlike the Milky Way, with its familiar spiral arms and flattened disk, M87 is a giant elliptical galaxy whose stars form a much rounder, more diffuse-looking system.
That center is anything but quiet. M87 contains a supermassive black hole about 6.5 billion times the mass of the Sun, while a spectacular jet of energetic material extends thousands of light-years from the galaxy. As matter gathers and heats up around the black hole, enormous amounts of energy are released, helping produce a jet in which particles travel at close to the speed of light.
In 2019, M87 made astronomical history when the Event Horizon Telescope collaboration released the first image of a black hole. The black hole itself emits no light. Instead, the image showed a bright ring of emission surrounding a dark central region—the black hole’s shadow, produced as its immense gravity bends and captures light around it. For the first time, astronomers could see the distinctive shadow predicted to appear around a black hole.
Virgo’s Stars Preserve an Ancient Harvest Story
There isn’t a single ancient story that explains Virgo’s identity as the Maiden. Different cultures and traditions associated the constellation with different female figures, but one theme appears repeatedly: agriculture, fertility and the harvest. We’ve already encountered traces of that connection in the stars themselves. Spica represents an ear of grain, while Vindemiatrix is the grape gatherer.
In Greek and Roman tradition, one strand associated Virgo with Demeter, goddess of agriculture, or her Roman counterpart Ceres, making the ear of grain held by the Maiden particularly appropriate.
A different tradition identified the Maiden with Astraea, goddess of justice. In the story of the declining Ages of Man, Astraea was said to have remained among humanity after the other gods had withdrawn, before eventually leaving Earth herself and taking her place among the stars.
These different traditions help explain why there is no single definitive answer to the question of whom Virgo represents. Over centuries, different stories became attached to the Maiden, while the connection with agriculture and the harvest remained particularly persistent. And although Virgo’s sprawling, relatively faint stars make a human figure difficult to recognize today, some of that ancient imagery remains embedded in the stars themselves: Spica still carries her ear of grain, while Vindemiatrix still recalls the grape harvest.
