Inside The Swiss Discovery Of 50 New Exoplanets Beyond The Milky Way

Talking with the team of Swiss researchers at the Observatory of the University of Geneva, who made the important discovery that will lead to a better understanding of planetary systems outside our own galaxy, the Milky Way.

GENEVA - For Michel Mayor of the University of Geneva Observatory, it was an impressive list of achievements: his team managed to discover no less than 50 new exoplanets orbiting around another star than our sun, thanks to the HARPS spectrometer located at La Silla Observatory in Chile. Sixteen of these planets outside our galaxy are "super-Earths' -- exoplanets that possess masses one to 10 times larger than Earth. The 50 exoplanets swell the ranks of the 604 "other worlds' that have already been discovered.

Why is this discovery important? Francesco Pepe, from the Swiss team, says the bulk of new information can be applied to ongoing studies. "We can now safely say that about half the stars that are similar to our sun are surrounded by at least one super-Earth," Pepe explained.

His colleague Didier Queloz adds: "What we have here is a number of planetary systems that are very compact. Whereas our solar system isn't. And we're trying to understand why."

Resonant planets

With the discovery, Queloz says the so-called Nice model hypothesis is gaining traction. "Jupiter and Saturn, because they were moving ‘in resonance" (ed : in a synchronic way), have played a crucial role -- thanks to their respective masses-- in the way the planets of our solar system are organized today," Queloz says. But as of today, scientists still haven't found a planetary system comparable to ours, nor have they yet discovered any "copy" of Earth, though that doesn't mean it doesn't exist. "There is so much background noise in the data we collect that it would take us years before obtaining anything reliable."

In order to hunt down "other Earths,", scientists will resort to more powerful telescopes, like the E-ELT (European Extremely Large Telescope) that is currently being built in Chile.

A Refuge From China's Rat Race: The Young People Flocking To Buddhist Monasteries

Unemployment, stress in the workplace, economic difficulties: more and more young Chinese graduates are flocking to monasteries to find "another school of life."

JIAXING — It's already dawn at Xianghai Temple when Lin, 26, goes to the Hall of 10,000 Buddhas for the 5:30 a.m. prayer.

Still half-asleep, the young woman joins the monks in chanting mantras and reciting sacred texts for an hour. Kneeling, she bows three times to Vairocana, also known as the Great Sun Buddha, who dominates the 42-meter-high hall representing the cosmos.

Before grabbing a vegetarian breakfast in the adjacent refectory, monks and devotees chant around the hall to the sound of drums and gongs.

"I resigned last October from the e-commerce company where I had been working for the past two years in Nanjing, and joined the temple in January, where I am now a volunteer in residence," explains the young woman, soberly dressed in black pants and a cream linen jacket.

Located in the city of Jiaxing, over a hundred kilometers from Shanghai, in eastern China, the Xianghai temple is home to some 20 permanent volunteers.

Unlike Lin, most of them only stay for a couple days or a few weeks. But for Lin, who spends most of her free time studying Buddhist texts in the temple library, the change in her life has been radical. "I used to do the same job every day, sometimes until very late at night, writing all kinds of reports for my boss. I was exhausted physically and mentally. I felt my life had no meaning," she says.
