Transit of Venus FAQ: Everything You Need to Know


“On June 5, skywatchers around the world will be treated to a rare astronomical event when Venus dances across the solar disk for the last time this century.

The so-called transit of Venus is a much-anticipated event that has attracted wide interest around the globe. To prepare for the historic spectacle, here are some frequently
asked questions (and answers) on the rare celestial sight 

What is the transit of Venus?

When Venus crosses in front of the sun, astronomers refer to this as a “transit.” As the planet moves along its orbital path, it will travel across the solar disk, making it appear to observers on Earth as a small black blemish on the face of the sun.

Due to the tilt of the planet’s orbit, transits of Venus are some of the rarest astronomical sights because they only occur in pairs eight years apart, once every 100 years or so. The last Venus transit occurred on June 8, 2004, and the next one will not be visible again until the year 2117, more than 100 years from now.

Prior to 2004, the last pair of Venus transits took place in 1881 and 1889.”

“It is absolutely true that the “hero” rhetoric that is attached to all things related to the U.S. military is used to shut down real debate about the merits of what exactly it is that all those heroes are doing out there. If all soldiers are heroes, then all soldiers are righteous. If all soldiers are righteous, then the soldiers’ cause is righteous. The soldiers’ cause is war. Therefore the war is righteous. This is one of the oldest tropes in the “Manipulating the Free Press During Wartime” handbook. You need only look back at the profusion of American flag graphics and distinct lack of pointed skepticism that defined the U.S. media in the run up to the Iraq War to know how well this tactic works. It is easy for a TV network and its pundits to be patriotic. Theirs is a cheap patriotism. It is a patriotism of platitudes and comfortable symbols and cartoonish enemy villains to be opposed. Dissenters are just easy weenies to be picked on in the media schoolyard.” Pundits, Platitudes, and Patriotism: War Heroes and Their Enemies (via azspot)
