The Moon Used to Be Closer

The Moon Used to Be Closer

The Moon hasn't always been where it is now. Four billion years ago, our day was six hours long because the Moon was much closer. It's been pulling away ever since, slowly enough you can't see it, but enough that total solar eclipses won't last forever.

Pluto: The World With a Heart

he most famous photograph of Pluto shows a heart. A bright, smooth plain on a darker, cratered face, roughly the size of Texas. Made of frozen nitrogen, it slowly turns over like a lava lamp on a million-year cycle. Nobody had ever seen it until 2015.

What Two Comets Are Leaving Behind

What Two Comets Are Leaving Behind

This week, Earth is walking through the dust of a comet that visited 40 years ago and won't return until 2061. Meanwhile, scientists released the first close-up data on an interstellar comet older than our Sun. Two comets, two timescales, the same week.

Waves Nobody Has Seen and Life Nobody Would Recognise

Waves Nobody Has Seen and Life Nobody Would Recognise

On Titan, a gentle breeze kicks up waves three metres tall that roll in slow motion. On a lava world, hurricane-force winds barely make a ripple. The same week, a new study asks: what if alien life can only be found by the pattern it leaves across many planets at once?

Neptune: The Planet That Shouldn't Be This Angry

On Neptune, the wind blows at 2,000 kilometres per hour. The planet sits thirty times further from the Sun than we do, where sunlight barely reaches. It should be a still, frozen marble. Instead it has the most violent weather in the solar system. Nobody is sure why.

Snows Metal on Venus

It Rains Diamonds on Neptune. It Snows Metal on Venus.

Two facts about weather in the solar system, neither of which involves water. Deep inside Neptune, methane is crushed into diamond and falls through the planet in a slow, impossible rain. On Venus, metals evaporate off the hot valleys and condense as frost on the mountains

Things Nobody Alive Has Ever Seen

Things Nobody Alive Has Ever Seen

Two sights arrived within a week of each other. Artemis II's crew watched a 54-minute solar eclipse from the far side of the Moon. A comet last seen by Neanderthals is now bright enough to catch with the naked eye. Neither will ever happen the same way again.
