On the winter solstice, a Truthdig review of the year's environmental stories finds cause for hope in our poison-riddled world.
In a major announcement, scientists suggest that flowing water exists on Mars -- a discovery they say has exciting implications for the future search for life on the Red Planet.
The entire planet will be hurt by climate change, but a bleak new report says some of the poorest countries will feel its effects the most.
Did you know that astronomers have found a bunch of potential "Earth 2.0" candidate planets scattered around the universe? More than 2,000 in fact, and one in particular, which NASA dubbed Kepler 22-b after the supercharged telescope that spotted it, spins around its own sun just 600 light-years away.
What happens when planetary bodies go rogue? Well, that's one universal mystery that scientists didn't actually know of until a team of Japanese researchers claimed to have found 10 such free-range roamers -- and what's more, they might be shockingly common in space.
Seeing as we're not doing so well with our planetary preservation program here on Earth, it might be prudent to consider the possibility of shopping around the universe for a new home at some point in the not-too-distant future. But how do we know which heavenly bodies are ripe for the human ruination treatment?
Could a scientific experiment 14 years and $8 billion in the making produce a tiny black hole that could eat the Earth? Or reduce the planet to a dead mass of "strange matter"? Two critics say yes and have sued in federal court to stop the Large Hadron Collider from smashing protons together this summer.
A team of scientists has discovered what could be the first habitable planet outside the solar system More information is needed before an accurate assessment can be made, but researchers have suggested that planet 581c has a temperature range of between 32 and 104 degrees, and could contain vast quantities of liquid water.
