NGC 2392 (Eskimo Nebula)
NGC 2392 also known as Caldwell 39, the clown face nebula and the eskimo nebula lies 3,000 light years away from Earth, located in the constellation of Gemini. A dying star sits at the center of the gas cloud, ejecting it's outlayers into the cosmos. The outer ring surrounding the dying star is made up of comet like structures which have streams of gas flowing from them, created by stellar winds coming from the central star. NGC 2392 was first discovered by William Herschel in England on the 17th of January 1787.
The image above was captured by the Hubble Space Telescope.

Pillars of Creation
The image above is composed of 32 sepearate images collected from the Hubble space telescope.
Located 8,000 light years away from earth in the eagle nebula, the pillars of creation are estimated to be between 3-4 million light years in length. The star forming pillars are made up mostly of dust and Hydrogen, the gas within the pillars are literally evarporating away due to the surrounding heat radiating from nearby stars. Some theorists speculate that the pillars may have been struck by a shockwave from a supernova almost 7,000 years ago. Because light travels at a "constant" speed, we won't see the destruction of the pillars for another 1,000 years. Other theorists state that stronger volumes of x-ray and radio radiation would have been measurable if the pillars had indeed been struck by a shockwave, but this is not the case.

Pacman Nebula ( NGC 281)
NGC 281 ( PacMan nebula ) is located in the constellation of Cassiopeia, 10,000 light years away from Earth. NGC 281 has a diameter, roughly spanning to around 90 light years in length.
NGC 281 is made up of a open star cluster which contains a few thousand stars, the multiple star HD5005 and dense clouds of cosmic dust and gas called Bok Globules. It is the luminosity of the stars within the nebula that cause the gases to glow, which can be seen in the image above.
The nebula was discovered by E.E Barnard in August 1883.
Bara Gumbad
Bara Gumbad is a historic monument situated in Delhi, India in Lodhi gardens. The monument is thought to have been constructed in around 1490CE. The exact purpose for the construction of the monument is unkown and still remains a mystery to this date. Bara Gumbad is 95ft high, 66ft wide and 66ft long. The monument is assembled of red, black, grey quartzite and sandstone. The interior of the monument is made up of various forms of artwork, colored tiles and elaborat carvings and inscriptions.

The Hour Glass Nebula
Image was took from the Hubble Space Telescope. |
The Hour Glass Nebula is a planetary nebula, located 8,000 light years away from Earth, in a small constellation named Musca. A planetary nebula is a giant cloud of gas formed from a Sun-like star undergoing the last stages of its life.
Near A Star's death, it blasts away its outer layers, leaving the stars dense core behind emitting ultra violet light, which ionises the gases around the star, causing the gases to glow. Different colours within the photo tells us about certain elements that are present. The red colours tells us that Nitrogen is present, the green colour tells us that Hydrogen is present and the blue colour tells us that Oxygen is present. The star's dense core will eventually cool down to the point where the forces of gravity will push it together to create a White Dwarf.

The Pinwheel Galaxy
M101 also known as the Pinwheel Galaxy, is a giant spiral disk, made up of stars, dust and gas located 23 million light years away from Earth, in the constellation of Ursa Major. The galaxy is 170,000 light years across in diameter, has a mass of around 110 billion solar masses with a black hole around 30 solar masses sitting at its centre .The galaxy holds giant molecular hydrogen clouds, which pull together under their own gravitational force, which in turn creates stars. The Pin wheel is home to over 1 trillion stars, with roughly 100 billion of these stars being very similar to our own Sun.
The photo above is the most detailed image of a spiral galaxy that Hubble has ever captured. The image is composed of 51 individual Hubble exposures. The shape of the galaxy is formed due to gravitational forces and stellar winds. The blue areas in the image are regions where new stars have formed, whilst the bright centre of M101 holds very old stars.

Veil nebula supernova remnant.
The image above shows the Veil nebulae supernova remnant, took from NASA's Hubble Telescope. The image is composed of 6 separate images, each image covers a distance of 2 light years. When all 6 images are put together it reveals this stunning view from the remains of a massive star, that exploded over 8,000 years ago. That star had a mass 20 times larger than that of our own sun. Different gases are contained within the remnant and are shown in different colours to create the image. The red/ orange colours tell us that Hydrogen is present, the green colours tell us that Sulphur is present and the blue colours tells us that Oxygen is present.

Teotihuacan - The city of the Gods.
Pyramid of the Moon |
Pyramid of the Sun to the left, Avenue of the Dead to the right. |
The temple of Quetzalcoatl |
The image's above show the ruins of Teotihuacan, located 30 miles away from mexico city Some theorists believe that it was the greatest city of its time.
The city was designed and built with long avenues and huge pyramids. The most central avenue in the city was named the street of the dead. The two largest pyramids where built of stone and named after celestial objects. One pyramid being named the pyramid of the Sun, the other was named the pyramid of the Moon.
The city was made up of 3 major pyramids with 200 smaller pyramids scattered across the city. Construction of the city started around the 1st century A.D. In 450 A.D almost 150,00 people lived there. The city stretches out nearly 20 miles, making it one of the ancient worlds largest cities.
After centuries of dominance the city suddenly collapsed, Its inhabitants left us with no documents or scripts to let us know what happened. The only things left behind where the monuments, artefacts and a few graves
The original people of the land we call the Teotihuacons, would be constantly repairing and re plastering the walls of the pyramids with lime plaster. Lime plaster is made by firstly burning limestone into a powder and mixing it with water. During the process of making lime plaster the limestone had to be heated to extreme temperatures in a stove by burning wood. A lot of wood would have been used to keep many stoves cooking the lime concoction at a steady heat, at around 800 degrees for 8 hours. Luckily for the Teotihuacanos the city was surrounded by dense forests, so finding wood to heat up the stoves was no problem. That was until they started using it all up. It's estimated that 30,000 tons of wood each year was used to maintain the plaster and pyramids within the city. That is roughly 3,000 acres of forest a year being destroyed over centuries. The forest would eventually never recover from this destruction, backfiring on the Teotihuacons significantly depleting their farm productivity dramatically. Theorists believe that Teotihuacan got so big and demanding that it simply couldn't maintain itself, causing the people of the land to migrate elsewhere, leaving Teotihuacan abandoned. Other theories suggest that Teotihuacan was burnt down after some sort of uprising or revolution occurred amongst the people within the city.
Some people confuse the Teotihuacons with the Aztec's who lived hundred of miles away from Teotihuacan. Some archaeologist believe that the Aztec's may have descended from the Teotihuacons. It was the Aztec's who discovered the site, 700 years after it was abandoned, and brought it into their culture. The Aztec's where blown away with the site, stating that, it was at this site where the Gods created the Universe, thus naming the site Teotihuacan, meaning "birthplace of the Gods".

The Orion complex.
The Orion complex (Orion Molecular Cloud Complex), is located in the constellation of Orion, roughly 1,600 light years away from Earth, estimated to be hundreds of light years across in size. The cloud is made up of different nebulae such as, dark nebulae, emission nebulae and reflection nebulae. These different nebulae have different characteristics, but they are fundamentally made up of vast amounts of gas, dust and a huge number of stars. The complex can be separated into different areas, with the Great Nebula in Orion seen near the centre of the image, the belt of Orion sits above it, whilst Barnard's Loop arcs around the left hand side of the image. Some parts of the complex can be seen through binoculars or with a telescope, but some parts can also be seen with the naked eye.

The Tadpole Galaxy
The Galaxy is a barred spiral galaxy located 420 million light years from Earth, near the constellation Draco. The tail of the galaxy is about 280,000 light-years long, containing stars and massive bright blue star clusters. It is said that a galaxy crossed in front of the Tadpole Galaxy, and was thrown around the Tadpole due to their gravitational attraction. Which in effect, left behind this trail of stars.

10 mind blowing images Space has to offer.
10.The Omega Nebula
Also known as the Horse Shoe Nebula, standing around 15 light-years in diameter found between 5,000 and 6,000 light years from earth. The super heated stars within the Nebula release radiation and ultra violet light which energises the gases within the cloud causing them to glow. The Omega Nebula is said to be one of the brightest and largest star forming regions of our Galaxy.
9.The Tarantula Nebula.
The Tarantula Nebula. Floats around at a colossal 3,800 trillion miles in diameter. It is known to be the most active star forming region within the local group of Galaxies. At the nebulas core lies a cluster of stars 35 light years in diameter which delivers most of the energy which makes the nebula visible.
8.The Emission Nebula.
7.The Horse Head Nebula.
The Horse Head Nebula is around 1,500 light years away from Earth. The nebula is situated on Orion's Belt. The cloud contains organic and inorganic gases made up of complex molecules as well as Hydrogen. The Hydrogen gas is ionized by a bright star that sits nearby called Sigma Orionis which produces a pinkish glow.
6.The Sombrero Galaxy.
5.The Crab Nebula
The Crab Nebula is simply the aftermath of a huge supernova. At the centre of the nebula lies a neutron star about 30 km in diameter which emits radiation and gamma rays energising the gases within the cloud. The nebula has a diameter of around 11 light years and is roughly 6,500 light years from Earth.
4.Merging Galaxies
3. Ultra deep field view of Space through the Hubble Space Telescope.
2.Planet Earth
Planet earth. The planet alone sits like a grain of sand, buried within our vast Universe. This Still doesn't compare to how small Planet Earth really is sitting within the dark abyss of Space.
1.The Sun.
The Sun. Sits roughly 93 million miles away from Earth. Boiling away like a huge ball of plasma. Yet this Star has enhanced life on our planet from the minute it was born. If the Sun was a touch out of place life on planet Earth would not exist.

5 Inventions that shape the way we live.
5.The Compass
Originally invented in China between the 2nd century BC and the 1st century, the first compasses where made of suspend-able pieces of magnetised iron ore. The freely suspended iron ore would always point to the magnetic poles helping people to navigate and pin point there location.
4.The Telephone.
In 1831 Michael Faraday came up with the basic principles in communicating with telephones but in 1861, Johann Reis a German inventor who built a system that converted sound into a series of electrical impulses at different frequencies then converted the electrical impulses back,creating sound. Around 1876 Alexander Bell experimented with the idea which is now known as the telephone. Alexander started his telephone company called Bell Telephone Company and developed mobile technology in 1924 manipulating it until cells would be put in mobile phones around 1983, creating a steady communication link between people using them.
3.The Internet.
The internet is simply a Huge global networking system connecting thousand even millions of smaller networks together. The internet model was formed in 1973 American computer scientist, Vinton Cerf. The design of the internet was complete in 1973 and published in 1974. People using the internet peaked to over 25 million by 1996. The internet has truly revolutionised the world, allowing us to bring a endless vault of knowledge straight to our front door.
2.The Light Bulb.
The inventor of the first electrical light was a English man called Humphry Davy, whilst the man credited for inventing the light bulb is Thomas Edison. In 1987 Edison created a bulb with a carbon filament contained in a oxygen free glass bulb that would not expire for over 1,500 hours. William David Coolidge was the man who mastered the design to the light bulb by changing the carbon filament to a tungsten filament, the bulb would last much longer.
1.Penicillin
Discovered by Scottish scientist Alexander Fleming in 1928. Alexander said he came across the mould when a Petri dish had been left unattended nearby a open window. Growth of some sort had formed on the open dish which just happened to be penicillin. Our understanding of the mould grew significantly and is vastly used around the world to help fight off negative bacteria that affects our body.
