A transit of Venus across the Sun takes place when the planet Venus passes directly between the Sun and Earth (or another planet), becoming visible against (and hence obscuring a small portion of) the solar disk. During a transit, Venus can be seen from Earth as a small black disk moving across the face of the Sun. The duration of such transits is usually measured in hours (the transit of 2012 lasted 6 hours and 40 minutes). A transit is similar to a solar eclipse by the Moon. While the diameter of Venus is more than 3 times that of the Moon, Venus appears smaller, and travels more slowly across the face of the Sun, because it is much farther away from Earth.
Hope some of you caught the Venus transit today, an event in which the planet travels across the face of the sun, appearing as a small, moving dot on its surface from observers on Earth. Don’t worry, if you missed it though – the next one is only in 100 years or so. I woke [...]
Summer is set to kick-off with a series of beautiful Venus related events, from an astronomical point of view at least. This week, the planet will appear at its brightest in the night sky, as it nears almost ideal observational circumstances – close distance to Earth and sun phase. Also, at the beginning of June, [...]
