If, as Brian F. Keane maintains, Americans' buying decisions are motivated by (a) I want and (b) I need , where does solar power fit in? Keane, president of SmartPower, a national nonprofit organization that creates community programs for energy efficiency and clean energy, says 80 percent of Americans want solar power, but only 3 percent obtain it. "That's because we don't think we need it, because our houses and offices already come...

By Derrick H. Pitts Considering the recent close calls our planet has had with various asteroids, meteors, and comets, it's time to develop an early-warning system - a cosmic "heads up" - to detect the wanderers zooming through the solar system. The major concern, of course, is whether any of these space travelers is on a collision course with Earth. Our geologic record clearly indicates that not only have we been hit before, but in one instance, the object was large enough to significantly change the planet's environment, triggering the demise of the dinosaurs about 65 million years ago. If they couldn't survive an impact, what chance would mere humans have to survive?

CAPE CANAVERAL, Fla. - Now's your chance to see the comet that passed within 100 million miles of Earth last week. Twilight on Tuesday will provide the best photo op for Pan-STARRS. It will be visible in the Northern Hemisphere just above the western horizon - right next to a crescent moon. California astronomer Tony Phillips said the glare of the setting sun may make it difficult to see the comet with the naked eye. But he encourages casual sky gazers to give it a shot. The moon will provide an easy point of reference.

True Green Capital Management L.L.C. and CIT Group Inc. announced the closing of $35 million of financing for a 12.3-megawatt solar rooftop system to provide power for the privatized housing community at Joint Military Base McGuire-Dix-Lakehurst in Burlington County. United Communities L.L.C., the owner of the 2,104-unit community, estimated the 13.7 million kilowatt hours produced each year by the system will provide about 40 percent of the community's annual electricity needs. United Communities is owned by First Montgomery Group of Marlton.

LOS ANGELES - It was too expensive. It lacked editorial focus. And for a digital publication, it was strangely cut off from the Internet. That's the obituary being written in real time through posts, tweets and online chats about The Daily, the first-of-its-kind iPad newspaper, which is being shut down this month. Rupert Murdoch's News Corp. said Monday that The Daily will publish its final issue on Dec. 15, less than two years after its January 2011 launch. The app has already been removed from Apple's iTunes, where it once received lukewarm ratings.

By Michael Lemonick Over the past few weeks, astronomers have announced not one but two extraordinary discoveries in the search for planets orbiting stars beyond the sun. The first was a world about the size of Neptune, 5,000 light-years away, whirling around in a solar system with four stars. It's something like Luke Skywalker's home world of Tatooine in the Star Wars movies, except that fictional planet sported only two suns. The second was an Earth-size planet right next door in the Alpha Centauri system, three stars that orbit one another not thousands or hundreds but a mere four light-years from our solar system.

Frank B. McDonald, an astrophysicist and former NASA chief scientist who helped design scientific instruments for research flights into space and who was a key force behind several initiatives and programs that helped scientists peer into the reaches of the solar system, died Aug. 31 after giving a speech at a scientific symposium in Ypsilanti, Mich. He was 87. The death was announced by the University of Maryland, where Mr. McDonald had been a senior research scientist at the Institute for Physical Science and Technology.

Not long ago, Gov. Christie and New Jersey environmental groups wound up on the same side of an issue. Some of the groups actually praised the governor they are so frequently confronting. Hold the gasps. The rest of New Jersey residents can cheer as well, because it benefits them. The state took action that will make solar power somewhat more affordable. So if you're a resident who has been mulling the idea, now is the time to re-mull. Basically the state increased the amount of electricity that utilities must obtain from solar power.

If we found life on another planet, the discovery would go a long way toward answering the deepest open questions in biology: How did life originate, how widespread is life in the universe, and are there alternative recipes for life? There's no obvious sign of life on any of our neighbors in the solar system. But desolate, frozen Mars keeps calling scientists back. In the Martian landscape, geologists see dry riverbeds and floodplains that hint at a warmer past that just might have allowed life to originate.
