There’s growing evidence that not just our Earth but also the solar system we know and love is actually a rarity, as such things go. Many stars, we now learn, have planetary systems. But very few are like ours. That’s a change from even the mid-twentieth century, when we considered our solar system to be … More Our solar system may be unique – let’s look after it
It’s SO COOL that we’ve found seven rocky and (broadly) Earth-sized planets orbiting a red dwarf star just 39 light years away. How cool?

It’s – well, figure this: it’s … More Five cool things about TRAPPIST-1 and its seven worlds

The Kepler space telescope, before being hobbled by mechanical failure, created a massive database of planet candidates orbiting the 150,000 stars it looked … More Searching for that elusive exo-Earth
I’ve always wanted to invent a time machine so I could whip back in time to stop Hitler before he did anything evil. Of course there are a couple of problems. First is I’d be joining the back of a LOOONG queue. The other is that our friend Albert Einstein tells us it’s impossible. But even … More The really annoying thing about time travel stories
Are you looking for a second Earth? We need to – humanity is on the fast track to ruining our one. Of course it’s not an easy task. A planet discovered the other week with the help of Kiwi astronomers underlines the problems. Four astronomers here in New Zealand contributed data to the OGLE microlensing … More Finding another Earth isn’t easy. Unfortunately.
