Transcript of The Scale of the Universe

-10
Carbon Atom
160 picometers | 1.6 x 10 m
Carbon is the basic element found in all living matter. Carbon is able to form more complex molecules when combined with other elements.
D-Glucose
800 picometers | 8.0 x 10 m
-10
Glucose is a simple sugar. While plants produce glucose using photosynthesis, humans consume it in order to provide energy to our cells!
Red Blood Cell
7 micrometers | 7 x 10 m
-6
Red blood cells are responsible for transporting oxygen throughout your body. They're the main reason why the rest of you can function. Around one quarter of your cells are red blood cells.
Visible Spectrum
400 - 700 nanometers | 4 - 7 x 10 m
-7
The part of the EM spectrum our eyes can see. They can be produced in a lot of ways, but mostly it is produced when electrons make quantum jumps.
Humans
1.7 meters | 1.7 x 10 m
0
Made of 75% water, we are the most technologically advanced creatures on Earth. Our ancestors have been on this Earth for more than 6 million years, yet it is nothing compared to how long the universe has existed
Blue Whale
With an average length of 30m and a weight of 170 tonnes, this monster is the biggest creature on Earth. However, these big blue creatures are quite docile and only eat krill.
30 meters | 3 x 10 m
Japan
615 km | 6.15 x 10 m
The Sun
The star at the center of our solar system. Although it is small compared to most stars in space, it produces more energy in a second than the total amount of energy humans used in history.
1.4 Gigameters | 1.4 x 10 m
Located off the east coast of Asia, this country is not even the size of the state Montana, but has a population of about half of the entire U.S. Japan is actually made up of four major islands: Honshu, Hokkaido, Kyushu, and Shikoku.
9
Asia
8,000 km | 8 x 10 m
Asia claims its place as the largest continent on Earth. Holding over four billion people, it has half the world's population.
The Solar System
Earth
12,700 km | 1.27 x 10 m

Estimated to be around 4.54 billion years old, this planet is what we call home. Earth is the only planet in our solar system that is capable of human survival. Since it's the only planet us humans can live on, we should take good care of it.
1
Formed around 4.6 billion years ago our solar system consists of the Sun, the 8 planets plus their moons and everything else that revolves around the Sun.
4.5 x 10 m

4.5 Terameters
VY Canis Majoris
Betelgeuse
Pistol Star
Rigel
470 million km | 4.7 x 10 m
11
97 million km | 9.7 x 10 m
The Pillars of Creation
Helix Nebula
7
This blue star is the brightest star in the Orion Constellation. It lies near the equator, so it is visible from almost anywhere on Earth.
10
The Oort Cloud
This bright blue star is one of the most luminous stars that we know of. In 20 seconds, this star radiates as much energy as our Sun does in a year.
As far as 100,000 AU away from the Sun, the Oort Cloud contains as many as 2 trillion bodies of ice. The objects that make up the Oort cloud are thought to be remnants from the formation of the Solar System.
1.3 billion km | 1.3 x 10 m
12
Betelgeuse is such a large star, it is expected to die soon. If this red giant was placed where our Sun is now, it would engulf all the planets up until Jupiter.
3 billion km | 3 x 10 m
12
VY Canis Majoris is currently the largest star that we know of. It is so big, you can fit around 7 billion Suns inside it.
2 light-years | 1.9 x 10 m
16
3 light-years | 2.8 x 10 m
16
Sometimes referred to as the 'Eye of God', this nebula is the closest nebula to the Earth. It is located in the constellation Aquarius and is only 700 light-years away. Only.
4 light-years | 3.8 x 10 m
16
The Pillars of Creation are actually a part of a bigger nebula known as the Eagle Nebula. About 7,000 light-years away, these Pillars were once destroyed by a supernova.
The Crab Nebula
11 light-years | 1.1 x 10 m
17
This nebula lies in the Taurus Constellation in the northern hemisphere of the sky. It is approximately 6,500 light-years away and was first recorded by a Chinese astronomer in 1054.
The Eagle Nebula
70 light-years | 7 x 10 m
17
The Eagle Nebula is a nebula in the constellation Serpens and was discovered by Jean-Philippe de Cheseaux in 1745-46. A lot of famous nebula images are actually just a small part of the Eagle Nebula.
Milky Way
120,000 light-years | 1.2 x 10 m
21
The very galaxy that we live in. In the night sky, it looks like a glowing streak because we are viewing it from within. Did you know that the Milky Way is almost as old as the universe itself? The Milky Way has been around for almost 13.2 billion years.
Andromeda Galaxy
150,000 light-years | 1.5 x 10 m
Containing about 1 trillion stars , this is our closest neighboring galaxy. It is moving at about 120 meter per second towards the Milky Way. The two are expected to collide in the future and form a larger elliptical galaxy.
21
Local Group
10 million light-years | 1.0 x 10 m
23
The Local Group is a cluster of 54 galaxies and dwarf galaxies. The two largest galaxies within the Local Group are the Andromeda Galaxy and our very own Milky Way Galaxy
Local Supercluster
Also known as the Virgo Supercluster, it is a group of more than 100 galaxy groups and clusters. It includes the Local Cluster, the Virgo Cluster, and many more.
110 million light-years | 1.1 x 10 m
25
Observable Universe
93 billion light-years | 9.3 x 10 m
28
Consists of all the galaxies and matter that we have observed. About 80 percent of all the matter in the observable universe is
dark matter
. They do not emit nor absorb any form of electromagnetic waves, but scientists can be sure of its existence "because something in the universe is exerting significant gravitational forces on things we see".
