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.

Making It Political Already? Why Turkey's Earthquake Is Not Just A Natural Disaster

The government in Ankara doesn't want to question the cause of the high death toll in the earthquake that struck along the Turkey-Syria border. But one Turkish writer says it's time to assign responsibility right now.

ISTANBUL — We have a saying in Turkey: “don’t make it political” and I am having a hard time finding the right words to describe how evil that mindset is. It's as if politics is isolated from society, somehow not connected to how we live and the consequences of choices taken.

Allow me to translate for you the “don’t make it political” saying's real meaning: “we don’t want to be held accountable, hands off.”

It means preventing the public from looking after their interests and preserving the superiority of a certain type of individual, group and social class.

In order to understand the extent of the worst disaster in more than 20 years, we need to look back at that disaster: the İzmit-Düzce earthquakes of 1999.

Because we have before us a regime that does not care about anything but its own interests; has no plan but to save itself in times of danger; does not believe such planning is even necessary (even as it may tinker with the concept in case there is something to gain from it); gets more mafioso as it grows more partisan — and more deadly as it gets more mafioso.
