...head is that its star is a red dwarf, only about one one-hundredth as bright as the sun. The dim light coupled with the planet's close proximity places it in what astronomers call the habitable zone: the spot at which temperatures remain comfortable and water can remain liquid. All this has led to a fair amount of astronomical hyperventilating. "On the treasure map of the universe, one would be tempted to mark this planet with an X," said Xavier Delfosse, an astronomer with Grenoble University in France and one of the planet's co-discoverers. Dmitri Sasselov...
...Even if we could visit 581c, there would be reasons to wait a bit before we light the rockets. For one thing, just because the planet could have liquid water doesn't mean it does. The body was detected like all extrasolar planets initially are, not by direct observation, but by measuring the infinitesimal gravitational wobble it causes in its home star. We won't get a clearer sense of its makeup until its orbit carries it in front of the star and the brief interference in the wavelength and intensity of the incoming light allows us to make some...
...dark ocean inside Europa. But the gravitational flexing of the little world caused by the movement of Jupiter's other moons heats up its innards the same way a wire hanger heats up when you bend it back and forth. This is what keeps Europa's ocean liquid, and this could could also help spark life...
...what Harvard’s Houses-to-be across the river in Allston extract in exchange for their commute, which will arouse sympathy even from Matherites. The UC’s funding policies won’t change before Mather covers 650 innocent people in gallons of liquid soap, so scores will have to be settled some other way—a gentlemanly duel, perhaps, or a campus-wide game of Risk...
...government believes that use of the scanner will greatly improve airline safety. A full body X-ray scan can reveal carefully concealed plastic weapons or liquid explosives that metal detectors miss. A 30-second scan in place of a pat-down or strip search would also greatly expedite travelers’ painfully slow passage through security...
