We are in for a celestial treat this weekend.
The snow moon, which is what tonight’s full moon has been dubbed, is going to be blocked for a time by a penumbral lunar eclipse. It’s called that because the moon will pass through the edge of the Earth's shadow, so it won’t be a full blown eclipse.
Comet 45P/Honda-Mrkos-Pajdusakova will be visible in the predawn hours by skywatchers using binoculars or small telescopes through Sunday, in the constellation Hercules in the eastern sky. The comet's closest approach will come on Saturday, when it will pass just 7.4 million miles (12 million kilometers) from Earth.
