Chladni Figures: Amazing Resonance Experiment

Chladni plate experiment

When I first saw this video I thought it was fake. Perhaps an April Fool’s joke. But, not only is it real, it is a phenomenon that’s been known for hundreds of years. Why am I just hearing about it? (there’s also a full version in which you can hear the tones: http://www.youtube.com/watch?v=1yaqUI4b974) So, what [...]

Heads Up! Thirteen Years Of Asteroid Impacts On Earth

pia17016-640

Since the Chelyabinsk event in early 2013, when a brilliant meteor fireball streaked across Russian skies and exploded with the energy of thirty Hiroshima bombs, humans have paid slightly more attention to the potential danger of asteroids than before. A combination of media attention and the viral spread of eyewitness videos and photos perhaps did [...]

                    Fatigue, that’s what. As a particularly frigid winter recedes across the north and east of the United States (we’ve become accustomed to milder weather in past years), the abuse suffered by asphalt roads is becoming apparent. If you’ve taken any form of surface transport recently [...]

Our high wilderness (Credit: T.A.Rector, I.P.Dell'Antonio/NOAO/AURA/NSF)

It’s only 240,000 miles away, yet this high wilderness still surprises and delights with clues about the origins of the solar system, Earth’s own water, and it even  supplies the occasional brilliant explosion. If you’ve been paying attention recently you’ll have noticed that the Moon is getting a lot of press. One reason is that [...]

To See Pieces Of Halley’s Comet, Just Look Up!

Halley up close in 1986 (Giotto mission, ESA)

It happens every year around now, and this year should peak on May 5th at approximately 9pm EDT (in the wee hours of May 6th if you’re on GMT). Little pieces of material that once belonged to the nucleus of Halley’s Comet will zip into our atmosphere as meteors. The Eta Aquarids (so-called because the [...]

Supernova Dust Fell to Earth in Antarctic Meteorites

Antarctic meteorite

Two primitive meteorites collected in Antarctica appear to contain grains of silica—the stuff of quartz and sand—forged in an ancient supernova that predates the birth of the solar system. In fact, some researchers believe that it was just such a stellar explosion that triggered the formation of the solar system from a cloud of dust [...]

Top 10 Space Stories of 2012

Space shuttle Endeavour lands at LAX

Now that 2012 has really and truly been put to bed, let’s look at the year that was in space exploration and astronomy.

California Meteor Broke Speed Record for Atmospheric Entry

Peter Jenniskens at Sutter

Meteor astronomer Peter Jenniskens must move quickly to trap evidence of a fresh meteorite fall. In 2008, a small asteroid roughly three meters across struck Earth’s atmosphere over northern Sudan, producing a brilliant fireball in the sky. The asteroid’s orbit had been tracked before striking Earth, upping the chances that searchers would be able to [...]
