I'm a longtime fan of cosmic disaster scenarios. Not because I'm particularly gloomy (according to my friends and family, I'm actually more of a goof), but because they are fabulous ways to illustrate the workings of the universe. They are also great for making you appreciate the delicate set of contingencies that allow us to exist right now, right here on Earth. I wrote one of the first Armageddon-science articles, entitled "20 Ways the World Could End," which was published for the 20 ...read more
But the stop-gap measure, now before Congress, includes a provision that some regard as a major step backward
For the 40 million people who depend on water from the Colorado River Basin, including me, there’s no escaping this stark reality: Our thirst for water exceeds what’s actually available.
That’s mostly because rising temperatures are sapping moisture from the environment even as demand for water resources in the region is going up.
The result: a run on the banks &mda ...read more

After a year of downtime to perform hardware upgrades, the Laser Interferometer Gravitational-Wave Observatory (LIGO) is ready for action and will turn on its twin detectors, one in Washington state and the other in Louisiana, on April 1. This time, it will also be joined by the Virgo collaboration based out of Italy, and possibly also by the KAGRA detector in Japan later in the year. Combined with the hardware upgrades, scientists expect these updates to allow LIGO to spot more observations ...read more
The Large Magellanic Cloud (LMC) and the Small Magellanic Cloud (SMC) are two of the most stunning naked-eye sights you can spot in the southern sky. Over the past few billion years, these two satellite galaxies of the Milky Way have been locked in a complex dance that has led to numerous interactions between them. And each time they get close, their gravitational forces disrupt the gas clouds within them, spawning the formation of thousands of new star clusters.
Now, astron ...read more
