IDL TIFF file 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

venus-transition-2012An 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

total-solar-eclipse-2012This 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

blue-moon-2016Moon 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

planetary-alignment-2015In 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

 each type are released by the comet. Comet ISON was fairly quiet until 1 November 2013, when a first outburst doubled the amount of gas emitted by the comet. On 13 November, just before this image was taken, a second giant outburst shook the comet, increasing its activity by a factor of ten. It is now bright enough to be seen with a good pair of binoculars from a dark site, in the morning skies towards the East. Over the past couple of nights, the comet has stabilised at its new level of activity. These outbursts were caused by the intense heat of the Sun reaching ice in the tiny nucleus of the comet as it zooms toward the Sun, causing the ice to sublimate and throwing large amounts of dust and gas into space. By the time ISON makes its closest approach to the Sun on 28 November (at only 1.2 million kilometres from its surface — just a little less than the diameter of the Sun!), the heat will cause even more ice to sublimate. However, it could also break the whole nucleus down into small fragments, which would completely evaporate by the time the comet moves away from the Sun's intense heat. If ISON survives its passage near the Sun, it could then become spectacularly bright in the morning sky. The image is a composite of four different 30-second exposures through blue, green, red, and near-infrared filters. As the comet moved in front of the background stars, these appear as multiple coloured dots. TRAPPIST (TRAnsiting PThis 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

leonid-meteor-storm-2015This 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

Spiral galaxy Messier 82 has long been known for its remarkable starburst activity, caused by interactions with its near neighbour Messier 81, and has been the subject of intense study for many years. On 21 January 2014, astronomers at the University of London Observatory in London, UK, pointed their telescope at the galaxy and spied something peculiar… an intensely bright spot seemed to have suddenly appeared within the galaxy [1]. This bright spot is actually a new supernova known as SN 2014J — the closest supernova to Earth in recent decades! Since its discovery, SN 2014J has been confirmed as a type Ia supernova, making it the closest of its type to Earth in over 40 years (since SN 1972E) [2]. This new NASA/ESA Hubble Space Telescope image is set against a previous mosaic of Messier 82 from 2006 (heic0604a), and shows the supernova as an intensely bright spot towards the bottom right of the frame. Type Ia supernovae are even more exciting for astronomers, as they have particular properties that we can use to probe the distant Universe. They are used as standard candles to measure distances and help us understand the scale of the cosmos. Catching such a supernova so soon after its explosion is very unusual; this early discovery will enable astronomers to explore its evolution in great detail, and to potentially infer the properties of its progenitor star. Messier 82 is several times more luminous than our Milky Way. Because it is only 12 million light-years away, it is one of the brighter galaxies in the northern sky. It can be found in the constellation of Ursa Major (The Great Bear). The supernova is currently visible through a modest amateur telescope, so why not see if you can spot it from your back garden? The image shown here was taken on 31 January 2014 with Hubble’s Wide Field Camera 3. This image is inset into a photo mosaic of the entire galaxy taken in 2006 with Hubble’s Advanced Camera for Surveys. Notes [1] The supernova was discovered at 19: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

solar-tornado-captured-on-the-suns-surface-2012On 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

earth-from-mars-and-saturn-2013An 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

Astronomical Sky Events 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.
