Rare Astronomical Events Today – Often interesting phenomena occur in the sky, not infrequently many even perpetuate them. Some astronomical phenomena are usually worth a step
1. Comet Lovejoy
This comet was first discovered by Lovejoy, an Australian astronomer. In early 2011, NASA said that the comet Lovejoy had ‘hit’ the sun. However, in fact this comet twice the size of a football field did not literally hit the sun, but only reached its closest point from the sun, about 140 thousand kilometers.
Remarkably, this comet survived as long as it passed through the hot atmosphere of the sun. Comet ‘collisions’ with the sun are not new, but they are quite rare. And generally, ends with the collapse of the comet.
2. Transit of Venus
Venus once passed in front of the sun as well as between the sun and the earth. Make it like a black dot in the sun. This is called a transit of Venus.
Venus transit phenomena always occur in pairs, with a patterned span of about 8 years. The events that occurred in 2004 and 2012 are indeed quite rare. A similar Venus transit pair will occur again in about 105 years, namely in 2117 and 2125.
3. Tetrad Bloodmoon
This event is quite rare. During the calculation of the Gregorian calendar, this event only happened seven times. A similar event is expected to return in 2033.

4. Perseids Meteor Shower and Delta Aquarids
This incident occurred in July-August 2013. This meteor shower occurs as a result of the earth’s passing with a cluster of dust remnants of comet 109P/Swift-Tuttle. The burning dust as it enters the earth’s atmosphere also makes it a meteor shower.
While the Delta Aquarids meteor shower is a meteor shower that comes from the fragments of comets Marsden and Kracht Sungrazing. The Perseids meteor shower is expected to return to Earth in 2136.
