Curiosity Rover Samples Air for a Taste of Mars History

It’s time to update the list of ingredients in Martian air.

In late 2012 NASA’s Curiosity rover drew air into its onboard laboratory and analyzed Mars’s atmospheric composition with a pair of spectrometers. The results of the investigation, published July 19 in Science, revise decades-old data on the makeup of Red Planet air and paint a broad picture of how the atmosphere has changed since the planet’s formation.

Physicists unveil results helping explain the universe

After a quarter-century of searching, scientists have nailed down how one particularly rare subatomic particle decays into something else — a discovery that adds certainty to our thinking about how the universe began and keeps running.

The world's top particle physics lab said Friday it had measured the decay time of a particle known as a Bs (B sub s) meson into two other fundamental particles called muons, 

The planets orbiting cooler stars have a warm climate

There is an assumption that the planets orbiting the cold star may not be on the surface of snow or ice, in contrast to those that rotate around hot. This is possible due to the interaction of starlight with ice and snow on the surface of the planets.
