Volans, a small and often overlooked constellation, swims through the celestial southern skies. Named after the flying fish by early seafarers, this constellation dazzles stargazers with its modest display of stars. Its creation is credited to the Dutch astronomer Petrus Plancius, who first depicted Volans in the late 16th century. The constellation was formed from stars that were once below the horizon in the Mediterranean region and therefore not included in ancient Greek star catalogs.
The constellation of Volans is significant not for its brightness or size, but for its historical connections to the Age of Exploration. Sailors navigating the vast oceans used the stars as a guide, and the introduction of Volans to maps helped them orient themselves in the unfamiliar southern hemisphere. Volans, along with other southern constellations, filled in the empty spaces of the celestial map, providing a fuller picture of the night sky to those intrepid explorers.
Today, Volans continues to pique the interest of astronomers and sky enthusiasts, becoming a point of interest in the broad tapestry that makes up the southern hemisphere’s astronomical observations. Its relative obscurity compared to larger, brighter constellations makes it a fascinating subject for those looking to expand their knowledge of the sky’s lesser-known aspects.
Volans Constellation Basics
Volans, the flying fish, is a small constellation in the southern sky. It’s notable for its origin steeped in mythology, distinctive stars, and its celestial location.
Origin and Mythology
Volans was named in the late 16th century by Dutch astronomer Petrus Plancius. He depicted it as a flying fish, inspired by the creatures found during explorations at sea. Volans represents the fish that was said to accompany the ship Argo Navis.

Gamma Volantis is the brightest star in the constellation. The composition of Volans includes:
- Multiple binary star systems
- White and yellow giants
- Main sequence stars
A standout feature is the pair of stars, Gamma Volantis and Beta Volantis, which dominate the constellation’s luminosity.
Location in the Sky
Situated in the southern celestial hemisphere, Volans can be seen from +15° and −90°. It’s bordered by the constellations Carina, Chamaeleon, Dorado, and Mensa. The best time to view it is in March.
key visibility points:

Notable Stars in Volans
The constellation Volans is home to several notable stars, each with distinct characteristics and attributes that make them stand out.
Beta Volantis
Beta Volantis is a yellow giant star, with a magnitude of approximately 3.8, making it the brightest star in the constellation Volans. It’s located around 108 light-years from Earth.
Gamma Volantis
Gamma Volantis is a binary star system that lies some 142 light-years away. The primary star is a yellow giant, shining with a magnitude of 3.9, while its companion is fainter and less massive.
Delta Volantis
Delta Volantis, situated around 663 light-years from Earth, is actually a triple star system. The main component has a magnitude of about 3.99 and is a white giant star.
Observing Volans
When aiming to observe Volans, it’s essential to consider the time of year and local atmospheric conditions. This constellation is best viewed in specific months and under clear skies.
Best Times to View
Volans, the flying fish constellation, is most visible to observers in the Southern Hemisphere. To catch a glimpse of Volans, stargazers should mark their calendars for the peak visibility months:
- January through March: This is when Volans is highest in the sky post-dusk.
- Late Southern Summer: Typically offers extended viewing opportunities.
Viewing this constellation is optimal when there’s a new moon, as the darker skies make the stars stand out more vividly.
Viewing Conditions
To ensure a fruitful observation, one must account for the local viewing conditions:
- Clear Skies: Essential for unobstructed views.
- Low Light Pollution: Darker locations, away from city lights, offer the best chances to see Volans.
- Altitude: Higher elevations may provide clearer skies.
For optimal observation, a telescope or binoculars can enhance the viewing experience, although many of the brighter stars in Volans can be seen with the naked eye under the right conditions.
Volans in Astronomy
Volans, the Flying Fish, is a small southern constellation that soars through the night sky. It is most notable for its deep sky objects and historical role in navigation.
Deep Sky Objects
Volans hosts a variety of galaxies, but none are particularly famous due to their faintness. The spiral galaxy NGC 2397 is among the more notable, picked out by telescopes for its well-defined arms and a supernova observed back in 2006. Then there’s the Lindsay-Shapley Ring, officially known as AM 0644-741, which is actually a ring galaxy located around 300 million light-years away.
Significance in Navigation
Historically, sailors in the southern hemisphere used the constellation Volans for navigation. Its presence near the South Celestial Pole made it an important constellation for nighttime travel. Unlike its more prominent neighbor, the Southern Cross, Volans is faint and challenging to spot, thus it was primarily helpful to seasoned navigators familiar with the southern skies.
Cultural Impact of Volans
Volans constellation, gliding through the southern skies, has woven itself into the fabric of various cultures. Its celestial form has inspired interpretations across art and influenced the traditions of southern communities.
Representations in Art and Literature
Artists have often looked to the stars for inspiration, and Volans is no exception. Paintings and poems frequently capture its bright stars. Maritime literature, in particular, recalls the constellation, using Volans as a symbol for navigation and exploration.
Influence on Southern Hemisphere Cultures
In indigenous southern cultures, constellations like Volans are more than just clusters of stars; they’re integral to belief systems and seasonal activities. Astrological calendars rely on Volans for tracking time. The constellation is also present in creation myths and storytelling, illustrating the close relationship between the cosmos and cultural heritage.
Frequently Asked Questions
In this section, readers will find answers to common queries about Volans, including its history, star composition, uniqueness, deep sky objects, and naming.
What’s the story behind the constellation Volans?
The constellation Volans was named in the late 16th century by famed Dutch astronomer Petrus Plancius. It is one of the 12 constellations created by Plancius from the observations of Dutch navigators Pieter Dirkszoon Keyser and Frederick de Houtman.
Can you name the brightest stars in Volans?
The brightest star in Volans is Beta Volantis, shining at a magnitude of around 3.8. Following close behind is Gamma Volantis, with a somewhat less luminous magnitude of 3.9.
What makes the Volans constellation unique?
Volans is unique in that it’s a southern sky constellation, often invisible to observers in the northern hemisphere. It represents a flying fish, an unusual choice among more common mythological creatures and objects depicted in the night sky.
Are there any cool deep sky objects to check out in Volans?
Yes, Volans is home to the Lindsay-Shapley Ring, a ring galaxy that’s thought to have formed from a colossal galactic collision. Another notable deep sky object is the NGC 2397, a spiral galaxy with active star formation regions observable by amateur astronomers.
How did the ‘flying fish’ constellation get its moniker?
Volans, Latin for “flying,” was attributed to the constellation because it depicts a flying fish, an animal known for gliding over the ocean’s surface to escape predators. This celestial flying fish skims the southern celestial waters as imagined by early astronomers.
What mythology is associated with the ‘flying fish’ in the stars?
There is no ancient mythology directly associated with Volans. Unlike many other constellations, Volans was not based on classical Greek or Roman myths but rather on the observations of sailors who saw flying fish while navigating the southern seas.
