Stardust and Moonbeams

Iris has so much going for it. It's a fashionable flower name. It's a mythological name, from the Greek goddess of the rainbow. And it's a classic name, always ranking in the girls' Top 1000 but now at its highest point ever.

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.

With a touch of celestial power, a hint of clunky charm, and the totally cool -o ending, Cosmo may well be finally shaking itself free of both the Seinfeld association (which made it a punchline of a joke) and the cartoon fairy association from The Fairly OddParents. In fact, it is in the Top 1000 in the UK and a favorite on Nameberry.

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.

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

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.

Stella is a name with star quality and sparkle, that manages to sound both ethereal and earthy. Celestial but not otherworldly, it lands somewhere between the popular Ella and bold Seraphina.

Esther was derived from the Old Persian word stāra, meaning "star." In the Old Testament, Esther, originally named Hadassah, was the captured Jewish wife of the King of Persia who risked her life to save her exiled people from annihilation. This story is celebrated by Jews on the holiday of Purim, so that it has traditionally been given to girls around that time.

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

Diana, the tragic British princess, inspired many fashions, but strangely, not one for her name. For us, Diana is a gorgeous and still-underused choice.

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.

Maybe it's because she shares that winning -elle sound with Isabel and Bella, but Estelle is no longer seen as a muumuu-wearing canasta player of a certain age (think George Costanza's mother on Seinfeld or Joey Tribbiani's talent agent in Friends). This could be in part thanks to the young Royal Couple of Sweden, who chose it for their firstborn daughter, or the single-named British R&B singer. It reentered the US Top 1000 in 2012 after a nearly fifty-year absence.

Seren is a top girls' name in Wales – and a lovely choice almost unknown elsewhere. Seren, in the Sirona form, was an ancient goddess of the hot springs.

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.

Sunniva was an Irish-born saint who fled to Norway, where she hid in an island cave with her followers and eventually died. After miracles were reported on the island, the cave was excavated and Sunniva's intact body was found. Sunniva is the patron saint of Western Norway. Her name would make a fascinating and unusual choice for a modern baby girl, and if her story is a bit grim, you can take refuge in the upbeat nickname Sunny or Sunni.

An attractive French word name known here via former child TV star Soleil Moon Frye, aka Punky Brewster. It started to be lightly used in the U.S. in the 1920s and is now attracting some attention as both a sunny nature and an international word name. It's currently in the Nameberry Top 500.

A starry-eyed, intergalactic name, far rarer than Stella or Esther. It's attached both to a comic book character and to Princess Astra on "Doctor Who".

Despite a rich history in Irish myth preceding its plantation appearance in Gone with the Wind, widespread use in the seventies caused Tara to lose its Irish accent.

Mars is a name with interesting potential, ticking the boxes as a mythological name, a space name, and a single syllable choice ending in -s. For parents wanting something unexpected, Mars could work as an alternative to popular Brooks, Max, Atlas, or Miles - and given to around 150 boys - and 35 girls - in a recent year, it is unusual but recognisable.

Celestine is a pretty, crystalline extension (actually a diminutive) of Celeste that would make a choice that is both delicate and strong. It is also a popular name in France.
