...Even Mayor's newest, smallest planets are unlikely to be pastoral places. All of them lie so close to their suns that they complete one orbit in 50 days or less - compared to the lazy, 365-day journey Earth makes - meaning that any water or incipient life on their surfaces would simply sizzle away. But HARPS is already sensitive enough to spot planets that are 100,000 times smaller than their parent star. Refinements both in HARPS itself and in the next generation of planet-hunting telescopes should make them able to spot smaller and smaller stellar wobbles. Those little...
...comets and more. With all that, you wouldn't think you could generate much buzz by announcing that astronomers had spotted a few dozen more bodies whirling about out there. But a buzz is just what was created yesterday at a meeting in Nantes, France, when Swiss astronomer Michel Mayor of the Geneva Observatory reported that he and his team had discovered 45 previously unknown planets orbiting a handful of nearby stars. There's good reason for all the excitement...
...Mayor himself was the one who spotted that first exotic world, and in the years since, he and other investigators have counted about 270 more. But land in the cosmic exurbs is decidedly inhospitable. Almost all of the newly discovered planets were huge, hot and gassy, Jupiter-like bodies lying scaldingly close to their suns. There might have been smaller, pleasanter Earth-like planets out there, but the equipment just didn't exist to spot the tinier telltale wobbles they would cause. Now it does - and it's delivered the goods...
...Thanks to the evocatively named High-Accuracy Radial-Velocity Planet Searcher (HARPS), a telescope mounted atop La Scilla Mountain in Chile, Mayor and his team were able to detect a litter of new planets, some as small as four times the mass of Earth - tiny by exoplanet standards. One star, just 42 light-years away, is home to a trio of such worlds - which Mayor is now calling "super-Earths." The largest of the three is just 9.5 times as big as Earth, the smallest just 4.2 times. It was not only the modest size of all the new worlds...
...even as the state braces for thousands more weddings in coming weeks, some of the most ardent supporters of same-sex marriage are casting anxious glances at the calendar and wondering how long the wedding bells will chime in California. San Francisco Mayor Gavin Newsom is one of them...
