The City skies are Polluted but not dead yet.

In our busy lives, we rarely look up to observe the wonders in the sky above. The is mainly due to two reasons: –

  1. We don’t have access to clear night skies.
  2. We are too busy looking into our computers and smart devices.

What we have forgotten over time is that the wonders of nature are as existent above as below. The night sky holds many secrets of our origins and to see some of that, one doesn’t need a telescope. Read through this article to find out the top 5 things that you can see in the night sky with you naked eyes.

  • The Moon

Our natural satellite is the brightest object in the sky after the Sun and on most days we can’t miss it due to its sheer size in the sky. The Moon is actually 1/4th the size of the Earth and is the largest natural satellite for any planet, ratio wise.

The Moon holds a very special place in human evolution and it can be  found in all kinds folklore and mythology. Here in India, almost all festivals are celebrated according to the Lunar calendar.

Examples are :-

  1. Holi (Sacred to Hindus) – On a full Moon
  2. Eid (Sacred to Muslims) – On particular moon phases only
  3. Diwali (sacred to Sikhs, Jains and Hindus) – On a new moon day
  4. Buddh Purnima (Sacred to Buddhists)  – On a full moon

Before the invention of the telescope, the only way to view the Moon was with the naked eye. As it was the brightest object in the night sky, several local names are direct translations “the Moon” across regions. There have been accounts in several encyclopedias and treatises across civilizations of Solar and Lunar eclipses (both caused by the Moon) and several poets and writers have glorified our natural satellite in their works. This brings the Moon to the top of our list.

You can find out about the current phase of the Moon, it’s rise and set time with a help of a free app called “Phases of the Moon”. It is available for Android and iPhone.

  • Stars (Constellations)

     

Embedded  in the pollution and glare of the city skies are not so bright but twinkly objects called stars. Every star that we see in the night sky is trillions of kilo meters away from the Earth is outside our solar system. In reality most of these stars would be much brighter than the sun if kept at its place but due to their sheer distance, we see them as dots in the the sky.

There are some stars, which are very bright and even in the most light polluted cities in the world, they can be viewed with little difficulty. There are software which can assist you in viewing the stars and the constellations they are in and with some planning and effort you can actually start locating  stars in the sky easily. One such software is Stellarium. It is a free distribution which is available for Windows, Mac and Linux operating systems. A paid version is available for Android which can be pointed  in the sky to know the name of the object you are looking at.

With the help of stellarium, you can see the sky of any place in the world at anytime and any date. You can plan whole overnight observations using this software. For those who are interested, you can also find your zodiac signs.

The software is very easy to use and for the novice, there are a lot of tutorials available on Youtube.

  • Planets

You will be surprised to know that even without a telescope or binoculars, you can view planets in the sky very easily. The word ‘planet’ comes from the greek word ‘planetes’ which literally means wanderers. If you observe them over several weeks, you can actually spot them hopping from one constellation to the other at a very slow pace.

The five planets which you can see in the night sky with unaided eyes are as follows:-

  1. Mercury
  2. Venus
  3. Mars
  4. Jupiter
  5. Saturn

Of these, Mercury is the most difficult to spot as it’s very close to the Sun and is also very small in size. The rest keep are easier to spot due to their separation from the Sun and their sheer brightness.

Stellarium, can be used to find out the position of planets and plan observations. Remember, it is very rare that you spot all the planets in the sky, all at the same time.

  • Meteors


    Every day about 30 tonnes of space debris enters the atmosphere of the Earth giving birth to shooting stars. In real, these are not actual stars but space junk like rocks, dust particles and ice pieces which fall on to the Earth due to its gravity. These space rocks move at a speed between 30,000 km/h to 60,000 km/h and when the enter the atmosphere of the Earth, the burn up due to the rapid fire of air molecules on them. This gives rise to the characteristic streak.

Sometimes, earth enters are a dust field (mostly the left over dust by comets and asteroids) and the rate intensifies. These meteors all seem to come from the same direction and are named after the constellation from where they seem to radiate. There are several meteor showers that occur every year and some of them put a really good show, even when seen from the city.

Here are some links which will help you plan in advance:-

  • Satellites

     

ISS Transits Moon

We have progressed a lot in the last century and a direct result of that is technological advancement. To make things easy for us, we create networks of communication and machines which execute that task. A very advanced form of such technology is Satellite Technology.

The first satellite ’Sputnik’ was launched in 1957 and since then, there have gotten only bigger. The likes of the International Space Station are the size of a football field and Astronauts live there and conduct experiments on long duration space travel and other things. The surface of these satellites, especially their solar panels are very reflective and can been seen from anywhere on the earth, even from the center of blazing sound and light show.

 

There several other satellites that you can see pass right above your head but they will be less brighter, so depending upon the sky conditions in your area, you can give spotting them a slot. The image above shows the passage of the ISS in front of the Moon.

You can plan your satellite observations using the following apps

App for Android – Heavens Above , App for iPhone/iPad – Satellite Watcher.
