From Bad Astronomy:

Astronomers have announced they have found a planet orbiting one of the stars making up the most famous star in the sky: Alpha Centauri, the closest star system to our own! At 4.3 light years distant, this is far and away the closest exoplanet known… and of course, it has to be.

Alpha Centauri is triple-star system, composed of a binary star, two stars much like the Sun – one slightly larger and hotter, called Alpha Centauri A, and the other slightly smaller and cooler, called Alpha Centauri B – orbited themselves by a red dwarf (called Proxima Centauri) much farther out.

The planet orbits close in to Alpha Cen B, and is technically called Alpha Centauri Bb – planets have lower case letters assigned to them, starting at b. Its mass is only 1.13 times the Earth’s mass, making this one of the lower mass planets yet found! But don’t get your hopes up of visiting it – its period is only 3.24 days, meaning it must be only about 6 million kilometers (less than 4 million miles) from its star. Even though Alpha Cen B is a bit cooler than the Sun, this still means the planet is baking hot, far too hot to sustain any kind of life as we know it, or even liquid water.

From Sky & Telescope:

On May 24, 2014, Earth will plow through a dense stream of dust particles shed by Comet 209P/LINEAR. Dynamicists think the crossing could result in an intense meteor shower — maybe even a "storm" — and North Americans will have front-row seats.

Over the past two decades, celestial dynamicists have gotten very good at divining when meteoric activity will spike. Their computer models can track how dust ejected by a comet near each perihelion pass gets distributed into strands of particles over time. Their calculations show that dust tends to stay concentrated close to the nucleus, and that the strands themselves often converge in space close to the orbit's perihelion.

Now these number-crunchers are telling us make sure May 24, 2014, is circled on our skywatching calendars. On that date, we might experience the most dramatic display of "shooting stars" in more than a decade.

From Spaceweather.com:

For the third day in a row, geomagnetic storms are circling the poles. In North America, auroras have spilled across the Canadian border descending as far south as Utah, Colorado, Kansas, and Nebraska.

The best place to see the show, according to pilot Matt Melnyk, is from the window of an airplane:

"I photographed an unbelievable display from the cockpit at 21,000 feet while flying across Alberta Canada," says Melnyk. "Being the pilot we get a front row view of the amazing aurora and this display was nothing less than spectacular!"

The storms were instigated by a CME strike on Oct. 8th and they are about to be re-energized by a solar wind stream due to hit Earth's magnetic field on Oct. 10th. NOAA forecasters estimate a 40% chance of strong geomagnetic storms during the next 24 hours, so high-latitude sky watchers should remain alert for auroras.
