I wish eclipse can occur more often
Me too. It's a pretty cool thing to see an astronomical object obscured by a shadow or another body.
Do you think there are categories of Eclipse that occurs?
There are eclipses that are an occultation, which means they are completely hidden, and there are partially hidden eclipses called transits
What are the measure one should take before viewing an Eclipse?
It would really depend if it were a solar or lunar eclipse. But the alignment of 3 objects is actually called a syzygy.
When did the first Eclipse occur? or has it been happening since the existence of earth?
Oh for sure. Solar and lunar eclipses have been happening for as long as earth has existed.
What benefit does an eclipse have for earth?
Solar eclipse
A solar eclipse occurs when a portion of the Earth is engulfed in a shadow cast by the Moon which fully or partially blocks ("occults") sunlight. This occurs when the Sun, Moon and Earth are aligned. Such alignment coincides with a new moon (syzygy) indicating the Moon is closest to the ecliptic plane. In a total eclipse, the disk of the Sun is fully obscured by the Moon. In partial and annular eclipses, only part of the Sun is obscured.
If the
Eclipse
An eclipse is an astronomical event that occurs when an astronomical object is temporarily obscured, either by passing into the shadow of another body or by having another body pass between it and the viewer. This alignment of three celestial objects is known as a syzygy. Apart from syzygy, the term eclipse is also used when a spacecraft reaches a position where it can observe two celestial bodies so aligned. An eclipse is the result of either an occultation (completely hidden) or a transit (partially hidden).
