...extraordinary may be too understated a descriptor for the discovery reported on Wednesday in the journal Nature: an international team led by Harvard astronomer David Charbonneau has spotted a "super-Earth," a planet 2.7 times bigger than Earth, circling a dim red star called GJ 1214, just 40 light-years away in the constellation Ophiuchus. "It's spectacular," says Geoffrey Marcy of the University of California, Berkeley, who is the world's most prolific planet hunter and is credited with discovering 70 of the first 100 exoplanets. "It's a top-of-the-top discovery in the quest for Earth...
Astronomers were further able to estimate the planet's makeup by calculating its size, based on the amount of light that GJ 1214b blocked when it passed in front of its star, as well as its mass (6.6 times Earth's mass), based on the wobble in the wavelength of starlight caused by GJ 1214b's gravitational pull on its star. That analysis revealed the new planet's density: about one-third of Earth's. Because water has a much lower density than rock, astronomers figured that the "most plausible scenario is a planet made mostly of water, with...
...left a little before midnight, when Cassandra got bored, even though Jeff's wife didn't look bored at all. But most people closed the party, then the bar and then went upstairs to Colleen's suite. And apparently the potent mixture of nostalgia, Coors Light and a $122 investment caused some possibly otherwise married people to hook up. This, it turns out, is the reason spouses go to reunions. I'm definitely going to Cassandra's. Sure, it was an all-girls school, but I'm not taking any chances...
