Joseph Nicephore - The man who drew with light

In 1827 a Frenchman by the name of Joseph Nicephore, was playing around with a technique called holography. He conducted an experiment which involved pointing a camera out of a window, positioning it so that the lens would cast an image onto a pewter plate, coated with a light sensitive filament. Eight hours later the image above was created and is believed to be the oldest known surviving photograph.

The Triple Star System, Gliese 667.

 Gliese 667A                   GlieseCb and GlieseCc                                               Gliese  667B                           Gliese 667C                                                                                                

Gliese 667 is a triple star system located 23.2 light years away from Earth, in the constellation of Scorpio. The Three stars, Gliese A, Gliese B and Gliese C all have a mass smaller than our own Sun and can be seen by the naked eye which appears as a single faint star in the night sky. The two brightest stars in the system, Gliese 667A and Gliese 667B is a binary star system, orbiting each other, separated by a distance of 12 AU. AU is a astonomical unit which tells us the distance from Earth to the Sun. So 12 AU, would represent roughly, 93,000,000 x 12 to calculate the distance in miles or 150,000,000 x 12 to calculate the distance in kilometers. The closest the pair of stars ever come to each other is about 5 AU, the orbit between the two stars takes about 43 years to complete. The third star in the system Gliese 667C orbits around the binary stars at a distance around 230 AU. The largest star in the system Gliese 667A is slightly smaller than our own Sun but has roughly the same volume of mass and is catagorised as being a brown dwarf star. Gliese 667B is the second largest star in the system, containing 70% the size and mass of our own Sun. Gliese 667C is the smallest star in the system and is roughly three times smaller in mass when compaired to our Sun. Gliese 667C is a red dwarf star or an M-type star with a outer atmosphere temperature of around 3,700 kelvin. Two planets have been found orbiting in the vicinity of Gliese 667C. The extrasolar planets orbiting Gliese C are named Gliese Cb and Gliese Cc. When on the surface of the extrasolar planet Gliese 667cc, Gliese 667C would look 3 times bigger in comparison when veiwing the Sun from the surface of Earth.

Statue of David by Michelangelo.

King David is regarded in biblical texts as a humble, honest and dedicated king whilst serving the needs and will of the people he ruled over at the time. Davids father Jesse was a farmer and lived in Bethlehem, he was of the tribe of Judah and his family are belived to have stemmed from the genology of Jesus Christ. Jesse had eight sons including David. In Biblical texts it is thought that the prophet Samuel was sent by God to find the next King of Isreal. The prophet presented each of Jesse's sons to God until God asked the prophet Samuel to annoint David, King over Isreal.

Hebrew prophets regarded him as the ancestor of the future messiah and according to the new testament he was the ancestor of Jesus. As Biblical texts go, the basic story of David goes that David was handed into the hands of King Saul ( King of Isreal ) to protect and take care of the King as one of his royal armour bearers. One of the most recognised stories about David is the story of David and Goliath, which tells us of a time when the Philistines and the Isrealites came to war with each other. The giant known as Goliath from the Philistines, challanged the Isrealites to send out their most decorated champion to fight him in a head to head battle. David stepped forward and killed Goliath with no more than a slingshot and a few stones.

The marble sculpture was created between 1501 and 1504 by  the Italian sculptor, painter, architect, and poet Michelangelo. This masterpiece stands around 17ft tall, located at the Galleria dell'Accademia ( Gallery of the Academy of Florence ) in Florence, Italy.

The Majestic Moon's of Jupiter.

Image of Jupiter and two of its largest moons. 

Jupiter's largest moon's Io and Europa were first discovered by Galileo Galilei whilst he was making observations of the night sky with his own personal telescope in 1610. The mythological character Zeus was another representation of the planet Jupiter, therefore Galileo named the two moon's of Jupiter after two lovers of Zeus, Io and Europa. Galileo recognised that not all celestial bodies orbited the Earth, this realisation would change the course of history forever. At the time of his discovery most astronomers believed that the Earth was at the centre of the Universe, now atronomers had to consider that Earth was simply apart of a much bigger Universe than previously thought. 400 Years later we have discovered 69 moons that orbit Jupiter with the use of Space Probes like the one that captured this stunning image. 

The image was captured by Nasa's JUNO Space Probe on September 1st 2017.

Pillars of Ashoka

The pillars of Ashoka are a collection of pillars dispersed throughout the Indian subcontinent, during Emperor Ashoka's reign of the Mauryan Empire.

The Emperor had inscriptions carved into the pillars, containing information about the Emperor's beliefs and ideas towards the teachings and philosophies of Buddhism. The pillars stand roughly 15 meters in height and weigh about 50 tons each. These pillars where then sent to areas like Pakistan, Nepal, Afghanistan and Bangladesh. The pillar shown in the image is believed to be one of 30 sandstone pillars inscribed with a Buddhists based moral code. The four lion pillar was constructed by Emperor Ashoka. The lion figure has since become the Republic of India's modern national emblem.

VY Canis Majoris.

VY Canis Majoris can be seen as the brightest star in the image above.

The Hypergiant VY Canis Majoris lies roughly 4,500 light years away from Earth in the constellation of Canis Major. It is one of the largest stars currently known within the Milky Way Galaxy, 1,700 times bigger than our Sun. Hypergiants are some of the biggest and most luminous stars in our known Universe, but only last for a few million years. Hypergaints like VY Canis Majoris are extremely rare stars to locate within our Galaxy. The first person to discover VY Canis Majoris was a French astronomer named Joseph Jerome Francois de Lalande in 1801.

The image above was captured at the Rutherford Observatory in Columbia University, New York, United States.

Mystic Mountain

The Mystic Mountain is vast area located roughly, 7,700 light years away from Earth in the Carina Nebula. The mountain is a stellar nursery, home to newly born stars, reaching a peak of around 3 light years (17,670,000,000 000 miles) in height. The stars surrounding and forming within the cloud, gives of huge amounts of heat and radiation, which ionizes the surrounding gases, causing them to glow. The image above was captured by Wide Field Camera 3 on the Hubble Space Telescope.
