On any average night, away from urban light, five or six such fiery space fragments appear as shooting or falling stars every hour. When our annual revolution takes us through zones heavily littered with disintegrated comet trash, we see the spectacular sky shows called meter showers.
August is the month to take all of this in. Whether you're a kid or an adult, this is the time to lie back in the grass, get out of town to experience a meteor shower, view the stars of summer, and share the universe with those you love.
Because comets contain large amounts of water and other ices, the notion that bombardments by comets deposited much of Earth's water has seemed to be almost a measure of faith. But a variety of recent studies place this idea into a somewhat harsh context.
Neil deGrasse Tyson is wrong. It pains me to write it but the world-famous astrophysicist, Director of the Hayden Planetarium in New York City and superstar of our field is a Supermoon hater.

While I'm astonished by the diversity of Earth's oceans, I'm absolutely floored when I stop to think that our beautiful blue ocean is only one of perhaps a half dozen or more oceans on other worlds in our solar system.
The deep ocean is not the only place where we can marvel at the wonders of nature. The heavens are another such place, and the Hubble Space Telescope, in particular, has captured for us some images about which we can truly say that they are "out of this world."
Could it be that our planet isn't typical at all? If so, then maybe life isn't typical either. On the other hand, if there are plenty of planets similar to Earth, we can reasonably hope for lots of cosmic company.
Let's watch the video and then discuss how you could use it to inspire and fascinate a student to think about scientific principles and material behavior.
It seems that the frequency of planets able to support life is roughly one percent. In other words, a billion or more such worlds exist in our galaxy alone. That's a lot of acreage, and it takes industrial-strength credulity to believe it's all bleakly barren.
It's that time of year again--a time of year space fans love! Those of you who saw my posts last year will remember that April 12th is Yuri's Night, t...
"When I first came to Santa Fe, it always snowed by Halloween and the ski area always opened by the end of November," observes Michael Wigley, a local skiing legend. "Now we are lucky if we have decent snow before Christmas.
This year Easter will be celebrated on March 31, but in 2014 it will occur on April 20. The reason has to do with the mismatch between the periodicity of the sun and the moon and the long history of human efforts to create a reliable and consistent calendar.
Living our 2-D lives on planet Earth, arguing over Sequestration and who has the remote, we tend to forget that the solar system is a cosmic shooting gallery. Comets serve as windows into the solar system's primitive past, and in 2013 we have two icy treats.
Until about five years ago, the moon was thought to be bone dry. However, the anhydrous view of the moon has been challenged by detections of water on the lunar surface and in rocks and soil returned by the Apollo missions.
