Perfect name for a Virgo or an Aries baby. It is also the name of a character in the fantasy Belgariad series.

Alcyone was the wife of Ceyx, but the happy pair angered the gods by calling each other Zeus and Hera. Ceyx's ship was sunk, Alcyone hurled herself into the sea, but then in sympathy for their grief the gods made the lovers halcyon birds or kingfishers.

Alula, the palindromic name of the first double star to be identified as physically related to its twin, would make the perfect name for a first-born twin. Ideas (we're only half joking) for the second born: Aviva, Aziza, Otto. Alula is reminiscent of the unusual name chosen by Isla Fisher and Sacha Baron Cohen for their second daughter: Elula, a month name from the Hebrew calendar.

The goddess name Aurora has consistently been on the US popularity list since the nineteenth century, but has really taken off in the past 30 years. Aurora also enjoys remarkable international popularity, ranking in the Top 100 throughout the English-speaking world as well as in Italy, Spain, Norway, Switzerland, and several other European and Latin American countries.

J.K. Rowling is a modern master of naming who brought a whole constellation of ancient and celestial names to modern parents. Bellatrix, of one of the stars of Orion, combines fashionable names Bella and Beatrix to make a convivial and original name. The down side: the Harry Potter character Bellatrix, played by Helena Bonham Carter, is a character so evil she's called a Death Eater, killing one beloved character and being murdered by another. And the name Bellatrix is so closely associated with that character that it might be challenging to sidestep the association.

Forget the oil. It's one of the twins that make up the constellation Gemini, and a mythological name on the cutting-edge of fashion; used by Metallica's James Hetfield.

Cosima, the kind of elegant and unusual name the British upper classes love to use for their daughters, is given to a handful of baby girls in the US after being chosen by two high-profile celebs in the same month; cool couple Sofia Coppola and Thomas Mars as well as supermodel Claudia Schiffer. It was used earlier by celebrity chef Nigella Lawson, while the male form, Cosimo, was given to the son of Marissa Ribisi and Beck.

Dramatic and worldly, Cosimo was chosen by singer Beck and his wife, Marissa Ribisi, for their son. Now that Cosima has emerged as a starbaby favorite, twin brother Cosimo could join her.

In Greek mythology, Elara was a lover of Zeus who gave birth to a giant son (ouch); it's also the name of one of the moons of Jupiter, giving it a celestial feel. Possibly derived from the Greek alara meaning "hazelnut" or "spear", it combines that favorite El- beginning with the popular -ara ending of Clara, Lara, and Amara, making it an all round appealing choice. Currently in the UK Top 1000, and on the rise in the US, it could be a fresher or less popular alternative to Ella, Lyra, or Laura.

Io may be one of the slightest names in the book, but there aren't many two-letter names with as much substance as this Greek mythological example. Io, a name used for the largest moon of Jupiter, was in classic myth raped by Zeus and escaped from him by changing herself into a cow.

Whether you think of it as Cale with a K, or a pet form of Kalen or Kaleb, this is just the kind of short, synthetic name finding a lot of favor now, but remember -- it's also the name of a vegetable.

Leo is a strong-yet-friendly name that was common among the Romans, used for thirteen popes, and is now at its highest point ever in the US thanks in part to Leonardo "Leo" DiCaprio.

The name of the Roman goddess of the moon, Luna is derived straight from the Latin word for moon, luna. Luna may be the name most likely to surprise someone from an older generation by its Top 10 status in the US and its widespread international popularity.

Lyra is a name with ancient and celestial roots that's finding new popularity thanks to its starring role in Philip Pullman's His Dark Materials series, seen in the movie The Golden Compass. Simple yet unique, Lyra hits the sweet spot between too popular and too unusual.

Nova has the feel of both newness, from its meaning, and great energy as an astronomical term for a star that increases suddenly in brightness before fading.

Orion is a rising star, with both mythical and celestial overtones.

Pan is the Greek god with the legs of a goat and the body of a pipes-playing man known for his mischievousness. Pan is also the god of shepherds, pastures, and fertility. Pan is also a Hindi name meaning leaf or feather.

Effortlessly cool with a hint of the mystical, Phoenix rolls a lot of trends into one: it's a place-name and a bird name, it ends in the stylish letter x, it's got in-built nicknames, and it's unisex too. Familiar but not over-popular, Phoenix ranks in the US and UK Top 1000s.
