Rare Cosmic Event to Transpire Tuesday Morning
Michio Kaku is a futurist, popularizer of science, and theoretical physicist, as well as a bestselling author and the host of two radio programs. He is the co-founder of string field theory (a branch of string theory), and continues Einstein’s search to unite the four fundamental forces of nature into one unified theory. He holds the Henry Semat Chair and Professorship in theoretical physics and a joint appointment at City College of New York and the Graduate Center of C.U.N.Y. He is also a visiting professor at the Institute for Advanced Study in Princeton and is a Fellow of the American Physical Society.
Kaku launched his Big Think blog, "Dr. Kaku's Universe," in March 2010.
You have two options: Stay up Late or Get up Early!It's been over thirty months since the continental United States in it's entirety has been able to view a total lunar eclipse. Keep your eyes on the sky next Tuesday morning, December 21st. The moon will hit a particular point in its orbiting cycle so that the Earth will be directly in line with it and our sun, giving us a total lunar eclipse. Keep an eye on the top left edge, where NASA states the "Earth's shadow will appear as a dark red bite at the edge of the lunar disk." Unlike a solar eclipse where the corona of the sun in its full brilliance will burn your retinas; looking at a lunar eclipse requires no special eye wear or protection. NASA states that the eclipse cycle is expected to last over three hours and will commence at approximately 1:33 a.m. EST (pay attention to upper left edge) and end just after 5:00 a.m. EST with the moon reaching a vibrant coppery-red coloration at about 3:17 a.m. at Mid-Eclipse. The moon will be completely in shadow from about 2:40 a.m. EST to 3:54 a.m.
In terms of location and visibility, NASA sums it up by stating: "The entire event is visible from North America and western South America. Observers along South America's east coast miss the late stages of the eclipse because they occur after moonset. Likewise much of Europe and Africa experience moonset while the eclipse is in progress. Only northern Scandinavians can catch the entire event from Europe. For observers in eastern Asia the Moon rises in eclipse. None of the eclipse is visible from south and east Africa, the Middle East or South Asia."
We can enjoy total lunar eclipses around every five years or so, but there is something extremely unique about next week's event. This particular eclipse will coincide with the December winter solstice, the longest night of the year. A total lunar eclipse on a winter solstice is a very rare event: the last one took place over 450 years ago. It might be a good idea to try and brave the cold for the viewing, even if it's for 10-15 minutes every hour or so until it's complete, because you won't be able to enjoy it again until around 2401. There will be another total lunar eclipse sometime in April 2014, but it will certainly not be as rare.
FORGE FX Simulations, in cooperation with Pearson/Prentice Hall, has created a Interactive 3D Learning Simulation. Click Here to enjoy the "real-time 3D simulation allowing you to control and interact with solar eclipses, lunar eclipses, and the different phases of the moon. The moon revolves around Earth in an elliptical orbit. It takes the moon about 27.3 days to orbit Earth once. This interactive 3D simulation demonstrates how this orbit causes the phases of the moon and eclipses."
How a cataclysm worse than what killed the dinosaurs destroyed 90 percent of all life on Earth.
While the demise of the dinosaurs gets more attention as far as mass extinctions go, an even more disastrous event called "the Great Dying” or the “End-Permian Extinction” happened on Earth prior to that. Now scientists discovered how this cataclysm, which took place about 250 million years ago, managed to kill off more than 90 percent of all life on the planet.
A new study discovers the “liking gap” — the difference between how we view others we’re meeting for the first time, and the way we think they’re seeing us.
We tend to be defensive socially. When we meet new people, we’re often concerned with how we’re coming off. Our anxiety causes us to be so concerned with the impression we’re creating that we fail to notice that the same is true of the other person as well. A new study led by Erica J. Boothby, published on September 5 in Psychological Science, reveals how people tend to like us more in first encounters than we’d ever suspect.
Using advanced laser technology, scientists at NASA will track global changes in ice with greater accuracy.
Leaving from Vandenberg Air Force base in California this coming Saturday, at 8:46 a.m. ET, the Ice, Cloud, and Land Elevation Satellite-2 — or, the "ICESat-2" — is perched atop a United Launch Alliance Delta II rocket, and when it assumes its orbit, it will study ice layers at Earth's poles, using its only payload, the Advance Topographic Laser Altimeter System (ATLAS).
