Catching Earth at aphelion

Do you feel a little… distant today? The day after the 4th of July weekend brings with it the promise of barbecue leftovers and discount fireworks. It also sees our fair planet at aphelion, or its farthest point from the ...

A new spin on Saturn's peculiar rotation

Earth's moon may not be critical to life

The Moon has long been viewed as a crucial component in creating an environment suitable for the evolution of complex life on Earth, but a number of scientific results in recent years have shown that perhaps our planet doesn't ...

'Hot Jupiters' provoke their own host suns to wobble

Blame the "hot Jupiters." These large, gaseous exoplanets (planets outside our solar system) can make their suns wobble when they wend their way through their own solar systems to snuggle up against their suns, according ...

Image: A peppering of craters at the Moon's south pole

(Phys.org) —The dark and shadowed regions of the Moon fascinate astronomers and Pink Floyd fans alike. Our Moon's rotation axis has a tilt of 1.5º, meaning that some parts of its polar regions never see sunlight – the ...
