Today we discuss the most popular and mind blowing astronomical sky events of the 21st century. These events happened because of gravitational force, continuous movements of planets and many changes in the system of stars. Some astronomical events are so rare that occurs after many years of the arrival of comets. Today technology capable the astronomist to see these amazing events and capture the images. Some of these events can see with naked eye. Most of them happen for a short time and disappear within a second.
But some are expected, and we can see them at the right place at the right time. Many astronomists capture the images of these events. These wondered the scientist and the whole world. Given below is the list of top 10 rarest astronomical sky events of the 21st century.
10. Venus Transition – 2012
An astronomical phenomenon happened last time in 2012 was Venus Transition. And It occurs when Venus planet comes between Sun and the Earth. This traverse Venus looks like a black disc within the sun shade as seen from the earth. This event occurs in every eight years. However, the position of Venus may vary within sun shade. It comes after 110 years period to the same situation as earlier transits. It was an excellent scene for the people.
9. Total Solar Eclipse – 2012
This mind-blowing astronomical sky events can see many times in a year and called the partial solar eclipse. But the Total solar eclipse is very rare. In this phenomenon Moon completely covers the Sun for a short time interval. The total solar eclipse recorded last time in November 2012. Moon makes 400 times closer approach to the sun as compared to earth and chances of full solar eclipse increased. When sun disc disappears into moon crescent and scientifically it is known as Umbra. According to the scientist, it will not happen for next 138 years.
8. Blue Moon – 2016
Moon has its charms in this world and people relates it to the Fairytales. What is Blue Moon? It is a second full moon in one month. This rare occasion happened when the first full moon falls at the beginning of the month and then blue moon falls at the end of the month. It happens very rarely in every two years. It has astronomical significant because it is possible it appeared in blue color due to atmosphere coloring particles. The first time it was looked in 1883 in blue color when in Indonesia exploded and filled the atmosphere with solid ash and Moon turns to blue in a full Moon day. It last happened on 21 May 2016 and next will occur in 2018.
7. Planetary Alignment – 2015
In the solar system, the possibility of planets alignments is a very rare phenomenon. It happened in May 2011, and last occurred in 2015. The Sun, Earth, Neptune alignment is seen which followed the earth-Venus, Mars alignment, and Mars- Mercury square alignment is active in the arrangement as mentioned above. It may be caused the earthquake, and this different alignment of planets continue from 4 September, 30 September 2015. And Earth Key date was 4 September 2015. Now this rare alignment will occur in 2040.
6. Comet ISON – 2012
This phenomenon is also known as Sun-grazing comet, and two Russian Astronomers discovered it on 12 September 2012. Comet ISON started from the edge of the solar system Oort Cloud. ISON of this century became extinct on 28th November 2013, and it is brighter than the full moon. It appears in parabolic shape and before merging with the sun it made a long journey of 3.5 billion years. During this journey, it gains the more length by addition of dust particles in every minute. By making a close approach of 750000 miles, it finally became extinct.
5. Leonid Meteor Storm – 2015
This phenomenon first discovered in 1833 and it occurred when Earth passed through the orbit of comet Tempel-Tuttle. There are 1000 meteors in an hour during Leonid meteor storm and continue for more than 15 minutes. This comet orbits around the sun in every 33 years. Last time it was seen in 2015 and it said that comet Tempel-Tuttle can produce in an hour about 100000 meteors.
4. Messier 82 Supernova Explosion – 2014
A cigar-shaped galaxy in Ursa about 11 million light years away from us is called as Messier 82. Some astronomy students in London discovered the first young supernova on 21 January 2014 which is visible from earth. They took the photo of Messier 82 and noticed that a new bright start found in the galaxy, Supernova 2014. These are rare astronomical objects and appeared in every 27 years.
3. Solar Tornado Captured On The Sun’s Surface – 2012
On 8 February 2012, something unusual recorded on the surface of the sun over a 30 hour period. The Solar Dynamics Observatory (SDO) showed beautiful and fascinating color video of the sun for two years. In the picture, A solar tornado on sun’s surface seen which create by magnetism. The Hurricanes on earth’s surface produce by wind. It was an amazing phenomenon of the 21st century which never seen before.
2. Earth from Mars and Saturn – 2013
An astronomical event captured from the Mars on 31 January 2014 which spotted the Earth as a pale blue dot from Mars surface. When we are seen from the earth mars looks like a red dot. This view was fantastic when they saw our moon is also visible orbiting our planet. NASA asked the earth inhabitants to smile and look to Saturn in the sky. When they captured, the photo the surface appeared as pale blue dot between two rings of the E and G ring and this unusual phenomenon was recorded on 19 July 2013.
1. Birth of New Moon – 2016
Cassini spacecraft took this image during his Saturn mission. He took a photo in which a new moon being formed and emerging from Saturn’s rings. It was named Peggy and 5 km in diameter, and it comes from the outermost ring of Saturn as it has many rings. Scientist believed this moon formed from icy particles in the rings and pushed towards the outer edge. Cassini captured these images in 2016 and wondered the world.

We conclude from this article astronomy make progress rapidly and discover many new things. These astronomical events can not record without the astronomical objects. I hope this article will be helpful for science related students. If you want to see these unusual astronomical events then wait , when it will happen next time in the 21st century.
