The sky's excellence - Supermoon!

Moon is the cool satellite for our Earth and its occupants. It influences the Earth's sea water, materials and also the minds of all the living creatures in it. It is needless to think further about the effect of the visible full moon. Now, this full moon is super in its size - Supermoon!

The hero of the night's sky - the Moon!

Mothers introduce our Moon to their children in their infancy itself: as they feed them each day with the dinner food, they point out at the serene moon. In the night's sky the moon is the sole attracting object than anything else. Each night it presents a new shape of its phases, that too at different times! It plays such for the kids, attracting them towards it :)

'Moving planet' - the International Space Station!

In our school days, we used to track any rare aeroplane that we spot on our skies with its booming sound. We shouted at the sighting of it to alert all other fellow students to view it. Now, it is needless to say about the reactions of sighting of a 'planet' that moves like an UFO! As I alerted about its visit this month, both adults and children reported back about its visit with awe. What is this moving 'planet'?

A flower on Martian surface!

We go on trekking to explore about animals or birds in the wild nature. Our such exploration extends also to other planets and moons. But here we include also extra-terrestrial living things, that are similar to us, the human beings. Over the years, we read and heard the news that signs of life, like water etc. does exist in other planets and moons. Recently, in December 2012 it has been reported in the news that a flower is found on the surface of Mars - a Martian Flower!

Moon's play - Waxing and Waning!

In the past adamant children were fed by mothers at dinnertime showing the mesmerizing moon on the sky; children too stopped their crying and chewed in the food seeing the charm of the moon. Children seem to be indulging in these thoughts: why this moon is not stable and goes on changing day by day - waxing sometimes and waning sometimes! OK. Now, why there are these waxing and waning in Moon?

Day and night cycles on Earth

We live on Earth depending mostly on daylight. After sunset we stop our main activities, take rest and go to sleep at night. This refreshes, repairs or rejuvenates us for the next day activities. These daily activities prolong our life on Earth. How these day and night are formed in a day's time?

Hide & seek by this wandering star - the Venus!

In my childhood I wondered and was also attracted towards many things. One such thing is today's topic. Before sun rise, I found often a brighter and bigger star shining on the clear dark sky. It enchanted me much. On some other days I found it missing. I wondered again where it had gone. On inquiring elders, I was informed about its name - Morning Star ('Vidi velli' in Tamil). But I could not get its whereabouts.

Merry-go-round, Earth and train are interrelated!

Science teacher at school explained why trees grown along the sides of railway track seem to 'run' back as one travels in a train. But I did not expect at that time that that explanation and my realisation will help me later in life to understand easily a mega event that happens daily! What is it?

Playing bright and dark on the sky!

Before 1960s, it was then a routine for the family members of the house to sit on the veranda or steps of the house at dusk and engage in gossips. Elders go on narrating about deeds and stories to the kids. In the midst of it they don't miss to point out at the bright stars shining on the sky. (My mom was then a guide to me apprising me about the 'Belt Stars' of the sky!). Messages about these wonders on the sky were passed on by mouths in such a way. At present also such wonders are shown to the public through daily news papers.

Tithis, the rule of Hindu families!

It is a well known fact that every Hindu temple ritual is being conducted on certain fixed and approved days of the month. These days' names can be found printed on each date-slip of a daily calendar. Do they belong to Astrology only? No, they have been so named simply, with respect to the phases of Moon only. They are called as Tithis (Lunar days, 'Thithis' in Tamil). For every thirty days these tithis repeat themselves. Among them there are two groups each having fifteen tithis.

Exciting Annular Solar Eclipse 2010!

When we are behind an object we will not be able to see any object that lies in front of it. It was learned by us as a child's play in our childhood. That is happening in a celestial hiding too - the Solar eclipse or the Lunar eclipse. In January 15th of this year 2010, here in Tamil Nadu of South India, we had the chance of viewing the Annular Solar Eclipse - an exact central fitting of Moon on the Sun leaving only an outer ring of Sun's disc unobstructed. This event was the longest one of this millennium; it happened at afternoon. I viewed it around 1.30pm IST. The following were also seen as an effect during the eclipse affecting the environment:

Comet, an Astronomical Wonder!

The arrival of comets on the sky is a wonder to astronomers. But it is also believed by others as a bad omen attached to the leader of a country where it is seen. I wonder about this belief like this: a comet is seen all over the world in the skies of all the countries; then is it a sign of death for all those leaders?

Comets are heavenly bodies that revolve (orbit) around our sun like all our planets. So, they are seen periodically near our earth. They do not move with speed as the Shooting stars, Artificial satellites or Space stations. They are seen on the evening or the morning sky when sun sets down or rises up. They slowly move each day farther and go far away to be seen like an airplane that disappears at a distance on the sky.

Comets show a tail when they are near the sun. They consist of ice, dust and particles of rock. As these they go far away from the earth they leave behind debris that are attracted by earth’s atmosphere. When all these fall down on the earth, they produce or present the show of Meteor shower.

Wonders on Earth and the Sky!

From the sky, looking down on our Earth will be always a surprise for all of us! Winding rivers that merge with the bluish sea at their ends reflecting the images of Sun or the clouds on their surface, brownish mountains with their wavy ranges, greenish forests, cumulus clouds floating just below our level like a sea of clouds that conceal earth’s surface, dazzling large water bodies such as reservoirs, trains moving like caterpillars in the cities – all these passing slowly backwards are wonders provoking excitement in us as we watch them with awe on traveling in a Jet plane over the skies here in India!

From the Earth, looking up on the sky also brings wonder in our eyes! On 5^th December 2008, there was a wonder on the evening sky: conjunction of the crescent Moon with the bright Venus and the Jupiter planets that resembled the present day Smiley, a smiling face having these planets as eyes and the crescent moon as its mouth! On 31^st December 2008, again there was a conjunction of the crescent Moon with Venus that had moved out of the previous place of conjunction leaving the Jupiter far behind it!

As we have seen many wonders to move behind us one by one in the Golden Year, 2008, let us all see up to the sky and pray to the Almighty to make this year, 2009 also full of many such wonders!

“Wish you all a Happy and Prosperous New Year!”

Shooting Stars - Meteors in Leonid Showers!

In our younger years of age, we used to gaze at the night sky and count the stars that appear, move and disappear – ‘Shooting Stars.’ While doing so, friends advised that one should immediately look at a green tree if he sees a shooting star; otherwise it might cause his death!

In 1998 November, there was news in dailies about ‘Leonid Showers.’ So, we all went to look upon the skies after midnight at about 01.30 am. The date was 18^th. You can read my jotting on my diary on that date:

“At night (1.30 am to 3.30 am) we all saw the meteors on the clear sky about one or two at a time in a gap of about 10 minutes from 2.15 am to 3.30 am”

As we waited with patience, there were these continued appearances of these shooting stars (or the Meteors) in showers. It appeared as if fireworks were lit and displayed in the sky at the Deepavali Day, here in India! An amazingly spectacular heavenly sight!

‘Meteoroids’ are the smaller separated parts from the Asteroids belt of stones that revolve around the Sun. When they come near our Earth, they are attracted and sucked into its atmosphere; but they catch fire and become visible as ‘Meteors.’ As they do so they get vaporized or fall down to the ground as ‘Meteorites.’ (It is believed that one large such of meteorites hit the Earth in Mexico and caused the extinction of Dinosaurs). But the Meteor showers of Leonid occur when our Earth passes through the dust particles left out by the comet Tempel-Tuttle.
Did these meteor showers come only in 1998? No, no! They appear each and every year around mid- November! So, you can witness this celestial event this year also in the Constellation of Leo. I wish you all have this wonderful experience! You can contact me for sharing your own rendezvous with these meteors or meteorites.

Venus - Our Sister Planet!

First, I wish you all and the kids a Happy Halloween Day! And wish the kids have nice ‘Treats by Tricking’ in this day!

Planets in the Solar system including our Earth rotate themselves in the direction from the East to the West. But with one exception – one of our planets rotates in the reverse direction! It is the planet Venus! On the land of Venus, our Sun rises in the West and sets in the East!

As this planet is close to the Sun as Mercury, it is seen near the Sun always – as ‘Morning Star’ just before sunrise or as ‘Evening Star’ just after sunset!

As it is closely similar in size and composition to that of our Earth, it is called Earth’s sister planet.

It has been named after the Roman Goddess of Love. It is known as ‘Sukra’ in Indian Astrology. It is stated in astrology that Sukra provides one with wealth!

Puzzling scientists still, the Venus is a wonder planet indeed!

The Belt Stars of the Heavens

Orderly objects attract all of us, especially if they are seen among the disorderly things. Such objects are also seen on the night sky. They are the ‘Belt Stars’ of the Orion constellation (The Belt of the Hunter). They are three in numbers, and are peculiarly arranged one after the other in a slanting manner as though they are in a line. They are Mintaka, Alnilam and Alnitaka. If they are joined by an imaginary line and that extended further leads us to another bright star Sirius in the South East of Orion (the Dog Star)! They are also seen enclosed in an (imaginary) square with bright stars in its corners such as Betelgeuse and Rigel. These all stars make up the Gemini zodiac (Mithuna raasi). They can be easily identified in winter as they are in the eastern sky at convenient hours. They were used in ancient times in navigation to find out the directions at seas.

From my childhood memories: I remember my mother saying to me, pointing to these three stars, that they are called ‘Water pots - on stand - stars’ (‘Thaunni chaal natchathiram’ in Tamil)!

Thanks to my mom who inspired me with astronomy by showing these wonder stars!

The Bright Saturn Identification

As the moon goes on revolving around the Earth, at one of its positions the Earth lies in between the Sun and the Moon. At night, in this position we see from earth our moon fully – a round Full moon. Similarly, the planet Saturn revolving around the Sun was seen as a round and bright - ‘Full Saturn’ on 24^th February 2008 (Earth was in between the Sun and the Saturn). It is said that this full and the brightest Saturn can be seen next only in 2015. But we can still now identify the planet easily but with lesser brightness. It is seen at night in the constellation of Virgo in the eastern skies or just above your head. It makes a triangle with two bright stars of the constellation each one of them positioning in the corners of that triangle – which can be imagined by connecting these corner points (objects) with imaginary lines. This triangle has its apex in the North and the base towards the South. Of the base-forming celestial objects, that one on the eastern corner is our Saturn! The planet will be visible so up to July this year in the night skies.

Installation of Stone Henges

Druids, the priests from the Celts of Britain are said to have built the Stone Henges. They must have thought like this: at certain periods of the year plants come out of soil and grow tall by getting the power from the Sun. Why our human race could not get power from the Sun too? To harness the power of sun, the priests could have used their astronomical knowledge to calculate the periods of solar activity and to find the important positions on their land where the infrastructures – the Stone Henges may be installed. Then they built the Stone Henges with the inner stones fixed in the important positions. The regularly arranged inner stones might have represented the seat positions of the King’s court. At certain periods of the year when the sun’s power could be harnessed the most, the King’s court could have assembled there and taken their special seats. Then the rituals might have been started to bestow the stability and sovereignty to the king’s court and hence to the entire kingdom.
