the

How To Locate The North Star

I'm Robert Massey I'm here from the

Royal Astronomical Society which is one

of the biggest astronomical

organizations in the world and we look

after the interests of astronomers not

just in the UK but across the world what

I'm going to do today is give you a few

pointers to get you started in a

strongly which i think is one of the

most incredibly interesting subjects

there is

if you want to find your way around the

night sky if you're just doing it as an

amateur astronomer just wanting to enjoy

the night sky perhaps in the first time

it's really important to know where some

of the stars in the sky are and to

identify the patterns they appear to

make what we call the constellations one

of the most important stars to find

actually tells you direction as well is

the North Star or the pole star Polaris

and from the northern hemisphere it's

really quite straightforward to find you

just need one really good trick a clear

night first of all is a big plus so you

can actually see the stars but if you

look for the constellation of the plough

or in the North America the Big Dipper

just this group of stars here and these

this these seven stars here are very

recognizable to many people you know

chances are you'll have seen them at

some point in your life and you look for

this bowl shape and this handle here and

the two stars on the right-hand edge of

the bowl in my picture a doobie and

Marik and if you follow a line up from

these two or down depending it depending

on the time of year track it up about

five or six times the distance between

them you come to the pole star or

Polaris and the great thing is once

you've found the pole star if you go out

in your back garden no matter what the

time of year what the time of night it's

always more or less in the same place in

the sky because it's directly above the

North Pole of the earth so the rest of

the sky turns as it appears to turn as

the Earth turns the pole star stays

where it is
