Across Southern California, sky watchers assembled Tuesday afternoon for a chance to view the last-in-a-lifetime transit of Venus. They donned protective glasses and peered into filtered telescopes to watch the planet as it crossed in front of the sun for the last time in more than 100 years. They spoke of watching a tiny black dot creeping ever so slowly across the solar disk with a combination of reverence and resignation. "It's like watching grass grow," said 93-year-old Don Nicholson, describing Venus' 6-hour, 40-minute progression, most of which was visible locally before sunset.

Jerry Schad had a simple explanation for his ability to quickly experience every mile he wrote about in his guidebooks, which helped expand hiking opportunities in Southern California: "I run through the boring parts and walk through the interesting ones. " His "Afoot and Afield in San Diego County," first published in 1986, is regarded as the preeminent guide to the region's trails. He followed it with two other well-regarded "Afoot and Afield" books, on Orange County and then Los Angeles County.

Astronomers have discovered a hidden collection of supermassive, growing black holes dating back to the early universe -- showing, for the first time, that black holes populated the cosmos far earlier than thought. The findings, published online Wednesday in the journal Nature, could help scientists understand how these black holes are born, how big they grow and how galaxies develop with them. "We know the nearest galaxies, like our own Milky Way, all have supermassive black holes in the center," said lead author Ezequiel Treister, an astronomer at the University of Hawaii.

How I Killed Pluto And Why It Had It Coming Mike Brown Spiegel & Grau: 267 pp., $25 Moon A Brief History Bernd Brunner Yale University Press: 290 pp., $25 Pluto. Poor little guy. He never wanted much. The others could be bigger, they could be better-looking or brag about themselves ("I'm burning hot!" or "I have rings!" or "I support life!"). He didn't care. All he wanted was to be part of the planet club. And for about 75 years, that tiny frozen world billions of miles from the sun was a card-carrying member.

When the moon blots out the sun's blinding rays on Sunday, a sliver of the Earth's surface will be plunged into eerie darkness. Travelers who have crossed thousands of miles to witness the celestial show will gaze at the sky and, for a few minutes, see a thing most people never get to see: a halo of fire — the sun's corona — flickering around the edges of the silhouette of the moon. But Jay Pasachoff, over on Easter Island, may be looking down more than up — calibrating his instruments, checking for technical glitches, peering through lenses.

Astronomer Frank J. Low, the experimental genius who developed and distributed sensors for infrared astronomy and performed the first successful observations above the Earth's atmosphere, died June 11 in Tucson after a long illness, the University of Arizona announced. He was 75.

Reaching a milestone in the search for Earth-like planets in the universe, two teams of astronomers say they have parted the curtains of space to take the first pictures of planets beyond our solar system. The first team, led by UC Berkeley researchers, used the Hubble Space Telescope to take a picture of a giant planet orbiting the star Fomalhaut, 25 light-years away. "It's almost science fiction," said Berkeley astronomer Eugene Chiang.

Talk about your cosmic pileups. An asteroid similar to the one that flattened forests in Siberia in 1908 could plow into Mars next month, scientists said Thursday. Researchers attached to NASA's Near-Earth Object Program, who sometimes jokingly call themselves the Solar System Defense Team, have been tracking the asteroid since its discovery in late November. The scientists, at the Jet Propulsion Laboratory in La Canada Flintridge, put the chances that it will hit the Red Planet on Jan.

Young galaxies, so faint that scientists struggled to prove they were there, have been discovered by aiming two of the world's most powerful telescopes at a single patch of sky for nearly 100 hours. An international research team has identified 27 pre-galactic fragments, "teenager galaxies," which they hope will help astronomers understand how our own Milky Way reached adulthood. The telescopes allowed scientists to see back 11 billion years or more, to 2 billion years after the Big Bang.
