New research suggests a tantalizing hypothesis: that the dark matter in the Milky Way caused the mass extinction 65 million years ago that killed off the dinosaurs, as well as other mass extinctions, which seem to take place somewhat regularly, with a period of some 35 million years.
At the same time that astronomers stole back Pluto, they delivered a bounty of new worlds to ponder. Thanks to arduous ground-based studies of nearby stars, and to the dazzling successes of NASA's Kepler mission, we now have a catalog of over 1,700 "new" planets orbiting hundreds of other stars.
Paradoxically, as we consider the easy-to-see light in the world, it is the hidden things lurking in the darkness that control much of the destiny of the universe, offers the rebirth of stars and solar systems from its substance, and allows us to see our sun's ineffable halo!
With its towering sandstone arches, out-of-this-world views, and miles of rugged landscape, Arches and Canyonlands are like no other places on Earth. But when the sun goes down, that's when the real show starts.
On a perfect rainy afternoon, a sold out crowd gathered at Theatre Works Silicon Valley for a panel and penultimate performance of Silent Sky.
Every time we appreciate science, whether it's being debated or moved forward with research, we should remember that we owe a great deal to this ancient philosopher, who opened up a new way in which to see the world.
As long as we view ourselves as "higher than" or "qualitatively different from" the other animals, we will continue to make assumptions about them that promote abuse and exploitation. The Scala Naturae gives us license to exploit other animals because they are seen as being further down the ladder.

Eccentric telescope pioneer and world-renowned astronomer John Dobson passed away this month at the age of 98. He revolutionized astronomy with a homemade telescope design now belovedly known as the Dobsonian Telescope and made the sky more accessible to the backyard star gazer.
While astrophysicist Neil deGrasse Tyson believes all individuals have a right to their own beliefs, he's passionate about what should be taught in science class -- science.
The light your eye captures from this object tonight has traveled through space since Galileo first used a telescope.
The phenomenon where our brains find seemingly significant patterns in images or sounds has an actual name: pareidolia. Remember this one if you want to impress in your next round of Scrabble or trivia night.
Jupiter is at maximum brilliancy, reflecting the greatest amount of sunlight straight back to us, and it's also visible all night, rising at sunset and setting at sunrise.
Over the next few days Earth will be passing through a stream of cosmic debris left in the wake of a near-Earth asteroid, 2003 EH1. Intersecting this trail of rocky particles means that some of these little guys will be pulled down into our atmosphere by Earth's gravity, causing a nice meteor shower.
At this time of year, people often ask for my astronomical/religious opinion: "What was the Star of Bethlehem?" What was this heavenly sign that a savior, that a Messiah, that Jesus was born? Can modern science prove what this object really was?
The milestone of our third mirror captures more than a moment in time, it heralds a rapidly approaching period of discovery.
