Scientists generate first map of clouds on an exoplanet
On the exoplanet Kepler 7b, the weather is highly predictable, an international team of scientists has found: On any given day, the exoplanet, which orbits a star nearly 1,000 light-years from Earth, is heavily overcast on one side, while the other side likely enjoys clear, cloudless weather.

Amazing.

Caleb Scharf:

No matter how conservative or optimistic we are, the statistics tell us that something like an astonishing one out of every seven stars must harbor a planet similar in size to the Earth, and at roughly the right orbital distance to allow for the possibility of a temperate surface environment. In other words, roughly 15 percent of all suns could, in principle, be hosting a place suitable for life as we know it.

Which is crazy, when you think about it. The likelihood of life not existing elsewhere becomes very small with these ratios.

But to discover whether or not we are alone, whether or not something akin to this Earth has happened somewhere else, and perhaps, just perhaps, whether or not there are other minds, on other worlds, thinking these same kinds of thoughts? That’s big, perhaps the biggest thing that could ever happen to a species.

physicsphysics:
An interesting model of our solar system’s path as it travels through space in the Milky Way.
Certainly a departure from usual models that show the Sun as a static object, which it certainly isn’t

Update: Lots of notes pointing to how flawed the video (that the GIF above is based on) is. Still, I find it interesting way to visualize that it’s not just our planet revolving around the sun, it’s our entire solar system revolving around the center of the Milky Way (and the Milky Way constantly moving as well).
