Finally, an Explanation for Mercury's Dark Surface

Comets didn't carry in the carbon, but rather disrupted what was already there

(Newser) - Mercury's mysterious surface darkness has baffled scientists: Though it's far closer to the sun than our moon, the latter reflects more sunlight. Last year, it was proposed that the root cause is carbon. As Patrick Peplowski of the Johns Hopkins University Applied Physics Laboratory tells the Christian Science ...

Why This Year's Taurids May Be Better Than Ever

Taurid's fireballs will be extra-enhanced by lack of full moon, dense debris field

(Newser) - Every year the Earth passes through the debris left behind by Comet Encke, and it's that time of year again, which means just one thing: Get ready for the fireballs. That's what you could see in the night sky over the next week or so as the Taurid...

Comet Is Spewing Out Vast Amounts of Booze

Study suggests building blocks of life arrived on drunk comet

(Newser) - Never mind water on Mars , they've found booze in a comet. Astronomers say they have detected ethyl alcohol among 21 kinds of organic molecules in gas from Comet Lovejoy, meaning the comet has the ingredients both to create life and to get it incredibly drunk. This is the first...

Coming in Jan.: Comet Visible to Naked Eye

Best viewing time for the comet will be mid-January

Lander 'Sniffed' Organic Molecules on Comet

But an attempt to get a soil sample may have failed

(Newser) - Before its battery petered out , the small spacecraft that landed on a moving comet managed to detect organic molecules on the comet, reports NBC News .

Comet Lander's Batteries Die

But it manages to send data to scientists

(Newser) - In a development that's no huge surprise , the comet lander Philae is entering what the European Space Agency calls "idle mode."
