If you're awake at 5 am, go outside and face east. About halfway up the sky, the red planet Mars and the blue star Regulus are side by side,...Look carefully to the left of red Mars.

A hole in the sun's atmosphere--a "coronal hole"--has opened up and it is spewing solar wind into space. Coronal holes are places where the sun's magnetic field spreads apart and allows solar wind to escape. A windy stream of plasma flowing from this particular hole should reach Earth on June 2-3.

In little more than a month, Comet PanSTARRS will cross the orbit of Mercury and probably brighten to naked-eye visibility as it absorbs the heat of the nearby sun. Sky watchers around the world will be looking for it in the sunset skies of early March, when it passes closest to the sun and to Earth.

Vladimir Scheglov sends the picture from the Kupol mine in the Chukotka region of Russia. "The Kupol mine has banned hunting, so wild animals are not afraid of people," he explains.

3D JUPITER: This just in: Jupiter is a sphere. You can prove it to yourself by staring at the stereo pair below and crossing your eyes. The third image that appears in the middle shows the shape of the giant planet in three dimensions.

Many sky watchers have witnessed a halo around the moon--a ring of light that surrounds the lunar disk at a radius of 22 degrees.
