Astronomers across the world are preparing for December’s Cold Moon on Saturday, the last full moon of 2018.

The exact time when the moon comes opposite the sun is 17.48, though witnesses will be able to see the full moon at any point overnight.

“It will be visible throughout the night, for anyone who has clear skies – the actual moment of the full moon, the point where the moon comes exactly opposite the sun in the sky will be at 17.48, so just coming up to six o’clock, but there will be no appreciable difference in how the moon appears,”

“As it stands, it’s looking rather cloudy, not completely overcast here in the South so there might be quite a lot of cloud, but if the cloud is thin cloud, then the moon is very dramatic anyway, being so bright in the sky thin cloud normally isn’t enough to stop the moon light coming through – and if you have a telescope or something like that you can usually see the details on the surface of the moon, even through a small amount of thin cloud.”


The astronomer warned that the moon may appear bigger but said this is just an illusion.

You will notice as well that when the moon is rising and setting when it’s a full moon in particular it has a tendency to look very large and this is an illusion created by our brains when things are close to the horizon.

“But also something that is not an illusion is that the rising and setting can take on quite a warm colour, sort of a yellow, orange tone and this is because moon light, which is sunlight bouncing off the moon, is being filtered through our atmosphere, so in the same way that sunsets look red, moon sets and moon rises also have a slightly reddish colour to them.”

Though there aren’t any noticeable differences in a full moon, the event does take place during the Ursids meteor shower, which could provide some extra special lunar photography.

The event is particularly notable this year as it occurs around the 50th anniversary of Apollo 8, the first time humans could see the whole of the planet at once.

First export of American furs

First export of American furs


Under the care of Robert Cushman, the first American furs to be exported from the continent leave for England aboard the Fortune.

One month before, Cushman and the Fortune had arrived at Plymouth Colony in present-day Massachusetts with 35 settlers, the first new colonists since the settlement was founded in 1620. During Cushman’s return to England, the Fortune was captured by the French, and its valuable cargo of furs was taken. Cushman was detained on the Ile d’Dieu before being returned to England.


Within a few years of their first fur export, the Plymouth colonists, unable to make their living through cod fishing as they had originally planned, began concentrating almost entirely on the fur trade. The colonists developed an economic system in which their chief crop, Indian corn, was traded with Native Americans to the north for highly valued beaver skins, which were in turn profitably sold in England to pay the Plymouth Colony’s debts and buy necessary supplies.



Drake sets out

English seaman Francis Drake sets out from Plymouth, England, with five ships and 164 men on a mission to raid Spanish holdings on the Pacific coast of the New World and explore the Pacific Ocean. Three years later, Drake’s return to Plymouth marked the first circumnavigation of the earth by a British explorer.

After crossing the Atlantic, Drake abandoned two of his ships in South America and then sailed into the Straits of Magellan with the remaining three. A series of devastating storms besieged his expedition in the treacherous straits, wrecking one ship and forcing another to return to England. Only The Golden Hind reached the Pacific Ocean, but Drake continued undaunted up the western coast of South America, raiding Spanish settlements and capturing a rich Spanish treasure ship.

Drake then continued up the western coast of North America, searching for a possible northeast passage back to the Atlantic. Reaching as far north as present-day Washington before turning back, Drake paused near San Francisco Bay in June 1579 to repair his ship and prepare for a journey across the Pacific. Calling the land “Nova Albion,” Drake claimed the territory for Queen Elizabeth I.

In July, the expedition set off across the Pacific, visiting several islands before rounding Africa’s Cape of Good Hope and returning to the Atlantic Ocean. On September 26, 1580, The Golden Hind returned to Plymouth, England, bearing treasure, spice, and valuable information about the world’s great oceans. Drake was the first captain to sail his own ship all the way around the world–the Portuguese explorer Ferdinand Magellan had sailed three-fourths of the way around the globe earlier in the century but had been killed in the Philippines, leaving the Basque navigator Juan Sebastián de Elcano to complete the journey.

In 1581, Queen Elizabeth I knighted Drake, the son of a tenant farmer, during a visit to his ship. The most renowned of the Elizabethan seamen, Sir Francis Drake later played a crucial role in the defeat of the Spanish Armada.

Origin of Species is published

On the Origin of Species by Means of Natural Selection, a groundbreaking scientific work by British naturalist Charles Darwin, is published in England. Darwin’s theory argued that organisms gradually evolve through a process he called “natural selection.” In natural selection, organisms with genetic variations that suit their environment tend to propagate more descendants than organisms of the same species that lack the variation, thus influencing the overall genetic makeup of the species.

Darwin, who was influenced by the work of French naturalist Jean-Baptiste de Lamarck and the English economist Thomas Mathus, acquired most of the evidence for his theory during a five-year surveying expedition aboard the HMS Beagle in the 1830s. Visiting such diverse places as the Galapagos Islands and New Zealand, Darwin acquired an intimate knowledge of the flora, fauna, and geology of many lands. This information, along with his studies in variation and interbreeding after returning to England, proved invaluable in the development of his theory of organic evolution.

 

 


The idea of organic evolution was not new. It had been suggested earlier by, among others, Darwin’s grandfather Erasmus Darwin, a distinguished English scientist, and Lamarck, who in the early 19th century drew the first evolutionary diagram—a ladder leading from one-celled organisms to man. However, it was not until Darwin that science presented a practical explanation for the phenomenon of evolution.

Darwin had formulated his theory of natural selection by 1844, but he was wary to reveal his thesis to the public because it so obviously contradicted the biblical account of creation. In 1858, with Darwin still remaining silent about his findings, the British naturalist Alfred Russel Wallace independently published a paper that essentially summarized his theory. Darwin and Wallace gave a joint lecture on evolution before the Linnean Society of London in July 1858, and Darwin prepared On the Origin of Species by Means of Natural Selection for publication.


Published on November 24, 1859, Origin of Species sold out immediately. Most scientists quickly embraced the theory that solved so many puzzles of biological science, but orthodox Christians condemned the work as heresy. Controversy over Darwin’s ideas deepened with the publication of The Descent of Man, and Selection in Relation to Sex (1871), in which he presented evidence of man’s evolution from apes.

By the time of Darwin’s death in 1882, his theory of evolution was generally accepted. In honor of his scientific work, he was buried in Westminster Abbey beside kings, queens, and other illustrious figures from British history. Subsequent developments in genetics and molecular biology led to modifications in accepted evolutionary theory, but Darwin’s ideas remain central to the field.

 

 

This Day In History Doctor Who is first broadcast on BBC TV

November 23, 1963: Doctor Who is first broadcast on BBC TV
The family science fiction show that would become a global phenomenon was first broadcast to a Britain shocked by the death of US President Kennedy a day earlier.

On November 23, 1963, the first episode of a family science fiction show which would go on to become a global television phenomenon was broadcast.

Doctor Who, the story of an alien traveller in space and time who finds adventure with his granddaughter and companions, had had a fraught beginning, its pilot episode re-shot after performance and technical errors.

 

 

Its eventual launch on Saturday 23 November was somewhat overshadowed by the news from America of the assassination of President John F Kennedy the previous day.

Viewing figures for the opening episode, An Unearthly Child, featuring William Hartnell as the Doctor, Carole Ann Ford as his granddaughter Susan, and Jacqueline Hill and William Russell as her teachers Barbara and Ian, suffered accordingly.

Source:https://youtu.be/OxqBjoITduU Series producer Verity Lambert persuaded BBC bosses to re-screen the first episode before the second was shown on the following Saturday. This enabled Doctor Who’s audience to build and led to an average of six million watching the first four-part serial.

The programme’s following instalment, entitled The Daleks, would consolidate its success with the first appearance of the Doctor’s arch enemies, and launch the BBC’s first ever merchandising boom.

Margaret Thatcher quits as Prime Minister after leadership challenge On November 22, 1990

After she failed to win enough support from Conservative MPs in a leadership contest, Prime Minister Margaret Thatcher resigned after 11 years at Number 10.

On November 22, 1990, Margaret Thatcher, the longest-serving Prime Minister of the 20th Century, announced her resignation from the office after 11 and a half years.

The Conservative leader chose to stand down after her Cabinet refused to commit their support to her ahead of a second round of leadership elections.

Growing party opposition to her stance over Britain’s involvement in Europe, a 14-point deficit to Labour in opinion polls, and the resignation of Deputy Prime Minister Geoffrey Howe had left her position in jeopardy.



She was challenged for the leadership by her former Defence Secretary Michael Heseltine; despite being defeated in the first ballot, Heseltine won enough support to force a second vote.

Initially Mrs Thatcher said she would “fight on and fight to win”, but consultation with her Cabinet persuaded her to withdraw.  Her Chancellor John Major and Foreign Secretary Douglas Hurd would go on to face Michael Heseltine in the second ballot, Major eventually winning the contest.

After meeting the Queen and making one final Commons speech, Mrs Thatcher left office, saying "We're happy to leave the UK in a very much better state than when we came here”.
