What is a transit of Venus?

When Venus passes directly between earth and only today discount cialis india the sun, we see the cialis for daily use distant planet as a small dot gliding slowly across the face of the sun.  Historically, this rare alignment is how we measured the size of our solar system.  The view is like a front row seat to the transit method, by which we find planets around distant stars.

When is cialis legal it?

The last transit of Venus occurred June 5-6, 2012.  The next pair of Sun-Venus-Earth alignments will be December 2117 and 2125.  Look for a transit of Mercury in 2016.

What happened in 2012?

People across the globe witnessed and celebrated science in action. Observing parties, public outreach, live webcasts, art exhibits, historic displays, music , and more set the 2012 transit of Venus apart as a collective science experience.

Transit of Venus Story


Rare Alignment

Sun, Venus, and earth align for transit of Venus
A transit of Venus occurs when Venus passes directly between the sun and earth.  This alignment is rare, coming in pairs that are eight years apart but separated by over a century.  The most recent transits of Venus were a thrilling sight in June 2004 and 2012, with the it's great! woman and viagra next transit of Venus pair occurring in December 2117 and 2125. 

Global Expeditions

Parallax angle from two locations
Observers from two locations on earth see two distinct paths (red and blue) of Venus across the sun.  The slight difference in times Venus takes, moving from edge to edge, can mathematically unlock the distance from earth to the sun, and thus the size of our solar system.  For 17th & 18th century transits, intrepid explorers set out to canadian healthcare answer a leading question of mankind.  Not all of them made the voyage back home.

Mystery of "Black Drop"

Simulated black drop smearJust before or after the circular black dot of Venus seems to touch the edge of the sun, a peculiar "black drop effect" sometimes occurs between the contact points.  A ligament of cialis order canada darkness smears the juncture of Venus and the sun.  You can see a similar anomaly if you almost pinch your thumb and forefinger together.  Just before you sense contact, a black feature spans your two digits.

Transits Lead the cialis levitra Hunt

Kepler mission's field of view near Summer Triangle
Once again, transits are on the leading edge of new discoveries.  The NASA Kepler mission and others are using the transit method to find habitable planets around distant stars.  The Kepler spacecraft monitors over 150,000 stars, looking for periodic dips in their light curves which reveal the presence of companion planets.  You, too, can join this quest for new worlds.

With the sun setting while the transit of Venus is still underway, the view over beautiful Lake Michigan is perhaps unrivaled.  Because no location in the mainland United States can guarantee clear skies, multiple transit of Venus attractions will give astronomy enthusiasts and casual observers alike plenty of reason to plan their visit here.  Among the anticipated highlights:

Hubble Space Telescope to Target 2012 Transit of Venus

Hubble Space Telescope soars over earth.The Hubble Space Telescope will be aimed at the moon to http://medicamentosseguros.com/canadian-pharmacy-viagra-prescription detect dips in brightness during the 2012 transit of Venus.  In an interview explaining how the Space Telescope Science Institute (STScI) allocates time on the telescope, Dr. Matt Mountain, STScI Director, describes a clever, high risk project with potential for high return that was selected among the http://davenportinstitute.com/cialis-professional 1,000+ proposals.

Alfred Vidal-Madjar, CNRS, Institut d'Astrophysique de Paris, submitted the proposal entitled Venus observed as an extrasolar planet.

While astronomers can discern the atmosphere of big planets 150 light years away, they seek to detect the atmospheres of smaller earth-size planets as well.  To mimic looking at a small exoplanet, the Hubble Space Telescope will measure small changes in light reflected off the moon as Venus diminishes the sunlight slightly when the inner planet passes between the sun and earth on June 5-6, 2012. 

"We don't know if it will work, but it's worth a shot," Mountain said. "If it does work, we'll get an idea of what earth-size would look like...It will guide us in the future if we ever see dip like it; we're seeing a very small planet...It's quite a risky project, but the viagra costs payoff would be quite remarkable, for we'd actually be able to measure the atmosphere of Venus using the Hubble Space Telescope."
