Astronomical phenomena have always been highly sought after across the world, throughout history. Whether it is for scientific research or astrology, astronomy has always been a hot topic.

Observing astronomical phenomena has become a great pleasure for astronomy enthusiasts. In this article, we will look at some rare astronomical phenomena in the world.

Blue Moon: A blue moon is a phenomenon that occurs when there is a second full moon in the same calendar month. The phrase "once in a blue moon" has come to mean something that rarely occurs. The last time a blue moon appeared was in 2018, and the next one is expected to be in August 2023.

However, a blue-colored moon, caused by certain colored particles in the atmosphere, is a rare occurrence. The last time this phenomenon occurred was in 1883 when Mount Kato erupted, and the entire atmosphere was filled with thick volcanic ash, causing the moon to appear blue.

Starry sky: The starry sky at night is a beautiful sight to behold. In places with no light pollution, you can see tens of thousands of stars, each with its own position and light. The Milky Way galaxy can be seen shimmering across the sky, making for a mesmerizing view.

Comets: Comets are strange objects in the solar system that often appear in the night sky with long tails and bright lights. When a comet passes by the earth, it provides a unique and unforgettable visual experience.

Meteor Showers: There are many meteor showers every year that can bring some spectacular sights as meteors streak across the night sky. At the best viewing times, you can see hundreds of meteors across the sky, leaving a deep impression on people.

Aurora: The Aurora Australis is a beautiful natural phenomenon that is usually seen in the night sky in polar regions. As the solar winds pass through Earth's magnetic field, they interact with gas molecules in the atmosphere, creating beautiful colors and shapes.

Total solar eclipse: A total solar eclipse is an astronomical phenomenon in which the sun's light is completely covered by the moon in some places on the earth.

Since the moon is smaller than the earth, a total solar eclipse can only be seen by people in the umbra of the moon. The most recent total solar eclipse occurred on December 14, 2020, in the southern hemisphere.

Halley's Comet: This periodic comet was discovered by Edmund Halley in 1531, and it is named after him. Halley's Comet has an orbital period of 76-79 years.

Its next perihelion pass will be on July 28, 2061. It is the first recorded periodic comet of humans, with clear records of its appearance dating back to ancient Babylon and medieval Europe.

Comet Hale-Bopp: Comet Hale-Bopp is a long-period comet. Compared with Comet Halley, Comet Hale-Bopp is a thousand times brighter.

The comet continued to approach the sun, and its luminosity continued to increase, reaching magnitude 2 in February 1997, and its blue tail facing away from the sun could be seen. Until January 2006, Japanese astronomers still photographed the comet in Australia.

The wonders of the night sky have always captured our imagination and filled us with awe. They make us curious about the mysteries of the universe and provide us with a beautiful and unique experience.
