HOW WATCH VENUS TRANSIT SAFELY
HOW WATCH VENUS TRANSIT SAFELY
( PROF WAQAR HUSSAIN 14/29-A SAMANABAD LAHORE)
The brightest planet Venus ,our neighbor,
is going to stroll in front of the Sun to stage rarest, unique celestial
phenomena for the last time in this century. The next transit will happen in
Dec 11, 2117.So, it is time to watch the belly-dance of Venus on 5-6 June
2012.The Venus will appear in silhouette as a small, dark dot -- appearing from
the left side of solar disk and moving to the right side-- will appear like a
child walking in front of cinema screen. This cosmic phenomenon occurs in pair
of eight years apart. The previous transit was 8 years back in June 2004, the
next pair of transit will happen in Dec 2117 and Dec 2125.So doesn’t miss to
watch!
The inhabitant of western hemisphere
(North America, South America, etc.) will watch this transit on 5th June,
2012 in dusk. While the people of Eastern hemisphere (Europe, Asia, Australia, etc.)
will watch the transit in dawn on 6thJune.
Last time this promenade was watched
by millions of people across the world. The event is so rare that only six Venus
transit have been observed since the invention of telescope by Galileo Galilei
in 1609--more than 400 years ago. Jeremiah Horrocks was the first to predict transit
of Venus in 1639 when he was just 21 year old.
Watching the Sun directly can damage
retinal cells, causing temporary and permanent blindness.So,don’t see the Sun.
Once recommended black and white film is not considered safe now.
Venus
transit should be watched by -- solar filter ; eclipse viewing glasses and slooh
space camera will provide a live broadcast of transit from site www.slooh.com but in Pakistan we have no access
to these techniques. So use pin hole camera, welding goggle, brown coloured
plexi glass of one inch thickness or see reflection in water.The other stories
circulating in sms’ are fake and are just creating panic.
