Contoh Explanation Text Tentang Gerhana Matahari Dalam Bahasa Inggris Beserta Artinya
Halo sobat IBI…
Gerhana adalah fenomena astronomi yang terjadi apabila sebuah benda angkasa bergerak ke dalam bayangan sebuah benda angkasa lain. Istilah ini umumnya digunakan untuk gerhana Matahari ketika posisi Bulan terletak di antara Bumi dan Matahari, atau gerhana bulan saat sebagian atau keseluruhan penampang Bulan tertutup oleh bayangan Bumi. Namun, gerhana juga terjadi pada fenomena lain yang tidak berhubungan dengan Bumi atau Bulan, misalnya pada planet lain dan satelit yang dimiliki planet lain.
Pada kesempatan kali ini IBI akan membahas explanation text tentang Gerhana Metehari atau nama bekennya Solar Eclipse. Langsung saja kita simak berikut ini.
a solar eclipse is a type of eclipse that occurs when the Moon passes between the Sun and Earth, and the Moon fully or partially blocks (“occults”) the Sun. This can happen only at new moon when the Sun and the Moon are in conjunction as seen from Earth in an alignment referred to as syzygy. 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 Moon were in a perfectly circular orbit, a little closer to the Earth, and in the same orbital plane, there would be total solar eclipses every month. However, the Moon’s orbit is inclined (tilted) at more than 5 degrees to the Earth’s orbit around the Sun (see ecliptic), so its shadow at new moon usually misses Earth. Earth’s orbit is called the ecliptic plane as the Moon’s orbit must cross this plane in order for an eclipse (both solar as well as lunar) to occur. In addition, the Moon’s actual orbit is elliptical, often taking it far enough away from Earth that its apparent size is not large enough to block the Sun totally. The orbital planes cross each other at a line of nodes resulting in at least two, and up to five, solar eclipses occurring each year; no more than two of which can be total eclipses. However, total solar eclipses are rare at any particular location because totality exists only along a narrow path on the Earth’s surface traced by the Moon’s shadow or umbra.
An eclipse is a natural phenomenon. Nevertheless, in some ancient and modern cultures, solar eclipses have been attributed to supernatural causes or regarded as bad omens. A total solar eclipse can be frightening to people who are unaware of its astronomical explanation, as the Sun seems to disappear during the day and the sky darkens in a matter of minutes.
Since looking directly at the Sun can lead to permanent eye damage or blindness, special eye protection or indirect viewing techniques are used when viewing a solar eclipse. It is technically safe to view only the total phase of a total solar eclipse with the unaided eye and without protection; however, this is a dangerous practice, as most people are not trained to recognize the phases of an eclipse, which can span over two hours while the total phase can only last a maximum of 7.5 minutes for any one location. People referred to as eclipse chasers or umbraphiles will travel to remote locations to observe or witness predicted central solar eclipses.
