Best answer: We get a 'shot' of radiation from just about everything in the galaxy. The issue is how far away these things are and the level of radiation emission. Pulsars are so far away, it ain't nothing to worry about. If this wasn't the case, we wouldn't be here anyway.

• ### Why is the moon higher in the sky during winter than summer?

Best answer: It's the 5.12 degree tilt of the plane of the Moon's orbit relative to the plane of Earth's orbit that does that. The Moon rises and sets and reaches higher altitude from September or October to March or April in the northern hemisphere, the opposite of what the Sun does.
