Meteor shower on April 21 - Source LT


Residents and amateur astronomers of the city will be able watch a meteor shower in Mhaismal at midnight, on April 21. It has been organised by Marathi Vidnyan Parishad (MaViPa).
The organisation's divisional secretary Sandeep Kulkarni said the meteor shower can be seen every year on April 21 or 22. He said that 20 to 30 meteors per hour can be seen, because of the meteor shower in the Lyra constellation, which had ten stars assigned to it by Greek astronomer Ptolemy in 150 AD.
"This is the most unpredictable meteor shower of the year. In 1982, an American amateur astronomer witnessed 100 meteors per hour in the Lyrid meteor shower, which is one of the oldest known phenomenon. Ancient Chinese astronomers have called this 'falling of stars'," he said.
Kulkarni said that the actual reason for meteor shower is earth's entry into an orbital path of comets. Every year in the end of April, the earth enters comet Thatcher's orbit path around the sun. The debris left by this comet enters earth's atmosphere, starting the meteor shower.
To watch the meteor shower, interested persons will have to register with MaViPa or at Pioneer's Secondary School, N-9, Pawan Nagar, Hudco, before April 18.
