EVOLUTION
The Milky Way began when clouds of gas and
dust started collapsi ng, pushed together by
gravity. Fi rst stars sprung up from the
collapsed cl ouds, those that we see today in
the globul ar clusters. The spherical halo
emerged soon after, followed by the flat
galactic di sk.

VOYAGER 1
Launched i n 1977
Speed of 61, 000 km/hr.
Covered a Di stance of 21.2 billion km so
far.
This means that i t takes 562 million years
for the Voyager 1 to leave the Milky way
and take a photo the ri ght angle in it's
speed.
DEMOCRITUS
First person who suggested that Milky way
is made up of stars

He used hi s telescope to di scover that our
Galaxy i s composed of bundle of stars and
bands of Li ghts
1 7 8 5 : W I L L I A M H ER S H EL
made the fi rst i mportant di scovery about
the archi tecture of the Mi lky Way Galaxy.
Using a l arge reflecti ng telescope that he
had bui l t, Wi lli am and hi s sister Caroline
counted stars i n di fferent di rections of the
sky.
However, We now know that Herschel was
right about the shape of our system, but
wrong about where the Sun lies within the
disk.
1910: HENTRIETTA
Also did some research to confirm that the
Herschel Map was correct.
1917: HARLOW SHAPLEY
Explored the galaxy, and said that we and
our solar system are not at the center of
the galaxy, we are too far from it's center.

Herschel Map was correct.
GLOBAL CLUSTERS

1920: EDWIN HUBBLE
Explores space wi th hi s telescope, to
discover that there are countless galaxies
in the uni verse, and that we live in one of
them

GALAXY
Is a col l ecti on or a combi nation of gas,
dust, and hundred of bi lli on stars together
with thei r solar system, wi th the help of
gravity, one of thi s galaxi es is the Milky
Way Gal axy.
ROMANS
Came from the Greek VIA LACTEA means
Road of Mi l k, because as they see it above
like a road of a Mi lk.
CHINESE
Chinese regarded the Mi lky Way as a “silver
river” that was made to separate two star
crossed l overs. To the east of the Milky Way,
Zhi Nu, the weavi ng mai den, was identified
with the bri ght star Vega i n the constellation
of Lyra the Harp. To the west of the Milky
Way, her l over Ni u Lang, the cowherd, was
associated wi th the star Altair in the
constel l ati on of Aqui la the Eagle.
GREEK
The anci ent Greeks vi ewed the Milky Way as
a spray of mi l k that spi lled from the breast of
the goddess Hera. In thi s l egend, Zeus had
secretly pl aced hi s i nfant son Heracles at
Hera’s breast whi le she was asleep in order
to give hi s half-human son immortal powers.
When Hera awoke and found Heracles
suckling, she pushed hi m away, causing her
milk to spray forth i nto the cosmos

WHY MILKY WAY HAS A
BULGE?
Milky way has a roughly spherical collection
of stars at i ts center called the bulge. How
this bul ge formed has been a long-standing
mystery, but many studi es suggesting that it
built up over ti me through multiple burst of
star formati on.

S T E L L A R S T R EA M
is a long, narrow associ ati on of stars in the
Milky Way hal o (or halos of similar galaxies).
They are i nterpreted as di srupted satellite
galaxies (dwarf galaxi es) or globular clusters,
pulled apart by ti dal forces.

Actually can be seen day and night, but the

Milky way and other larger galaxies have a
giant Bl ack Hole i n there center. I n our
galaxy i t i s called Saggi ttari us A star.
IS ALL GALAXIES HAVE A
BLACK HOLE?
Black hol e i s a place i n space where gravity
pulls so much that even li ght can not get
out. And thi s i s the responsi bly why a galaxy
becomes more bi gger, because of pulling
other dwarf galaxi es to i t.

Weight of our Galaxy: 7 Billion- 2 trillion
times heavi er than the Sun as estimated.

NAMAN!
Milky way gal axy, also travels in the universe
because of gravi ty, everythi ng in the space is
moving due to thi s reason.
ITS ROTATION IS AROUND:
210 KM/SEC
ITS SPEED:
IS AROUND 2.1 MILLION KM/HR
1929: EDWIN HUBBLE
discovered, that galaxi es are moving away from
us, the more i t i s further, the more it is faster
to
move,
that' s
why
our
universe
is
continuousl y expandi ng and the factor that
made thi s happened i s called dark energy.
DARK ENERGY
drives cosmi c obj ects apart at an increasingly
rapid rate rather than drawi ng them together as
gravity does, that leads to the universe to
expand.

W H Y I T B E C O M ES E L L I P T I C A L G A L A XY ?
The stars that previ ously followed circular
orbits wi thi n two relati vely thin disks get
scattered i n all di recti ons and form a puffedup, roughl y football-shaped ( elliptical) galaxy.
IS EARTH SAFE AFTER THE ADROMEDA
AND MILKY WAY COLLISION?
Dependi ng on the posi ti on of the solar system,
Earth can be exposed to more radiation from nearby
stars resul ti ng i n i nhospi tabl e temperatures.
So far they Andromeda are 2.5 million light
years apart fi l led wi th gravi ty they are rushing
towards each other wi th the speed of 402, 000
km/hr.
GALAXY
is responsi bl e for i ncreasi ngly rapid of drawing
the cosmi c obj ects together.

The gal axi es are movi ng towards into Centaurus
Constel l ati on (The Great Attractor), it has a
diameter of 300 mi lli on light years, the
astronomers
thought
that
it
is
just
a
Suppermassi ve Black hole, but in year 2005
with the hel p of X-ray Astronomy, they found
out that i n thi s place there is a larger
supercl usters called NORMA CLUSTER (AKA.
The great Attractor).
