VN can enjoy Lyrid meteor shower on Sunday

Vietnamese who enjoy astronomic phenomena will be able to observe the Lyrid meteor shower on April 22, 2012, said the Vietnam Astronomy and Space Association.

Nguyen Duc Phuong, an expert from the association, said the meteor shower may be seen in Vietnam at around 2 am that day, and observers should be able to identify it in the northwest direction.

Many other countries in addition to Vietnam will also have a chance to enjoy the interesting meteor shower, he said.

The Lyrids, which is a medium-sized meteor shower, generally begins on April 16 and ends on April 26, with the maximum amount of meteors generally occurring during the night of April 21/22. At this time, hourly rates can reach about 20 meteors per hour, Phuong said.

Meanwhile, NASA officials estimate a maximum meteor rate of about 15 per hour, but the number could be higher or lower than this, according to

However, the fascinating phenomenon can be hard to observe in Vietnam if there are many clouds at that time, Phuong said.

According to some space websites, the Lyrids are particularly intriguing to many for two reasons.

First, observations have been identified back to at least 2,600 years, which is longer than any other meteor shower. Second, the meteor shower occasionally experiences an outburst of about 100 meteors per hour for unknown reasons.

A meteor shower is a celestial event in which a number of meteors are observed to radiate from one point in the night sky. These meteors are caused by streams of cosmic debris called meteoroids entering Earth's atmosphere at extremely high speeds on parallel trajectories.

Most meteors are smaller than a grain of sand, so almost all of them disintegrate and never hit the Earth's surface. The chunks of debris die a fiery death in our planet's atmosphere, leaving bright streaks in the sky to commemorate their passing.
