18 Illuminating Facts About Telescopes

Telescopes have done more to transform man’s understanding of space than most other inventions. This is what makes them so interesting.  It is also the reason why some of these amazing facts about telescopes are going to fascinate so many people:

The Past

  1. People always credit Galileo with the invention of the telescope but actually, that isn’t true. That honour goes to Hans Lippershey. He invented the telescope in 1608.
  2. Speaking of Galileo, he was the first person to use the telescope for astronomy. It was his innovative work that led to the discovery of Jupiter’s satellites. His eventual blindness is attributed to the fact that he used the telescope to look directly at the sun.
  3. For a time, the biggest telescope was the Leviathan (Parsontown). It weighed 40 tons and it came into existence in 1845, built by the Earl of Rosse. But it had to be decommissioned due to poor weather.
  4. The most famous telescope at the moment is the Hubble telescope. It was officially launched in 1990, seven years later than planned. There were delays. The light-collecting mirror wasn’t polished to the right accuracy. This issue was only fully corrected in 1993.
  5. The first telescopes were used by merchants to see approaching trade ships. This supposedly gave them some sort of advantage that they could use to beat the competition.

The Future

  1. Ever since its launch in the 1990s, scientists from other countries have been working night and day to produce a superior telescope to Hubble. A European-led team believes that they can deliver a telescope whose images are 15 times sharper by 2024.
  2. NASA, which is responsible for Hubble, has no intention of losing the telescope race. Their goal is to put a radio telescope on the moon by 2030, beating anything Europe could ever hope to achieve.
  3. Work is being done in South Africa and Australia to deliver a radio telescope that will produce an exabyte of raw data every single day. if the telescope works as promised, the data it generates will exceed global internet traffic.
  4. China already has a robotic telescope on the moon. It has been there since 2013 and it is expected to remain in operation for three decades, gathering vital data.

The Present

  1. The telescopes of today are operated remotely using computers and the internet.
  2. Scientists can use the telescopes of the 21st Century to see 13 billion light-years away. This is the equivalent of looking back at the beginning of the universe.
  3. The ‘Large Binocular Telescope’ is situated on Mt. Graham in Arizona. Not only is it one of the largest telescopes in the world but, as per the name, it looks like a giant pair of binoculars.
  4. The Hubble Telescope has photographed every planet in our solar system except for Earth, which is too close to the telescope, and Mercury, which is too close to the sun.
  5. The Hubble telescope, which is in Earth’s orbit, is controlled by NASA personnel using radio signals. It was designed to perceive infrared, visible, and ultraviolet light. The sun and new stars emit ultraviolet light, so Hubble can observe them.
  6. The most famous pictures to come from Hubble are the so-called Pillars of Creation in the Eagle Nebula.
  7. The biggest radio telescope in the world has a dish that spans 1,000 feet across. It is situated in the jungles of Arecibo in Puerto Rico.
  8. The Catholic Church has two telescopes: one in the Vatican Observatory and the other at the Mount Graham International Observatory.
  9. The Hubble Telescope is the size of a school bus, but it weighs 11 tons.

18 Fun Facts About Spinach

There was a time when spinach was the most despised food item on the market. But perceptions have changed. People have grown to appreciate its nutritional value, with some of the more interesting facts surrounding Spinach including:

History

  1. The Spinach plant originates in Persia. It came to China in the 7th Century, Europe in the 12th Century, and the United States in the 1800s. The food item has been with us for many centuries
  2. If you have ever wondered why some Chinese people call Spinach ‘Persian Green’, they are merely honouring its origins.
  3. The King of France was married to a woman called Catherine de Medici in the 16th Century. A native of Florence, she was obsessed with Spinach. This matters because, today, food recipes that use Spinach in a significant role have the term ‘Florentine’ in their name.
  4. The Popeye cartoon from the 1930s changed the perception of Spinach in the USA, boosting consumption by an estimated 33 percent.
  5. The reason Spinach consumption was low in the first place was because of a cartoon the New Yorker published in 1928 that showed a child displaying utter contempt for Spinach.
  6. The word ‘Spinach’ comes from ‘ispanai’, which eventually became ‘Spanachia’ in Spanish and, in turn, became ‘Spinach’. ‘Ispanai’ means ‘Green Hand’.

Nutrition

  1. To enjoy the nutritional benefits of Spinach, you must eat it fresh. Otherwise, it tends to lose its properties with each day that passes.
  2. You can refrigerate Spinach to preserve it but it is still going to lose half of its nutrients by the end of the week. Spinach must be frozen if you are to keep it fresh.
  3. Half a cup of Spinach (cooked) will give your body 10 percent of all the iron you need to consume each day. Iron is good for the body. It increases your energy levels, improving endurance in the long run.
  4. Spinach is also a source of Vitamins B, A, C, E, and K, not to mention calcium, and magnesium. It has been credited with the regulation of blood pressure, management of diabetes, and improvement of eyesight, to mention but a few.
  5. In the First World War, haemorrhaging French soldiers were served Wine blended with Spinach juice. They wanted the Vitamin K in Spinach to make the blood of these soldiers thicker.
  6. Spinach isn’t all good. It has large amounts of Vitamin K1, which can cause blood clotting. Additionally, Spinach has oxalates. If your body can’t tolerate them, they can cause kidney stones.
  7. To escape the threat of oxalates, you are encouraged to boil Spinach. This will eliminate the oxalic acid.

Random Facts!

  1. Believe it or not, there is such a thing as National Spinach Day. It falls on the 26th of March.
  2. China produces over two dozen tons of Spinach every single year. They account for 92 percent of all the Spinach produced in the entire world.
  3. While eating Spinach is healthy, it is even healthier to drink it. Turning the stuff into juice releases beta-carotene, which improves the efficiency with which your body absorbs the food item’s nutrients.
  4. To grow Spinach, you need to provide cool and moist conditions. Spinach also thrives in sandy soil.
  5. The United States produces more Spinach than every other country except China. But its production only accounts for 3 percent of the total global production.

17 Amazing Facts About Sheep

Most people think they understand sheep. But these creatures are far more nuanced than you realise. Here are 17 interesting facts that prove as much:

Biology

  1. A sheep’s wool never stops growing. This is particularly true for domestic breeds of sheep. A sheep that hadn’t been sheared for years produced nearly a hundred pounds of fleece in 2015.
  2. Sheep pupils are not like human pupils. First of all, they are rectangular in shape. Secondly, they have 320-degree vision―that is vastly superior to the 155 degrees that human eyes offer. The pupils of a sheep are critical to their survival because they are the prey of so many creatures.
  3. Sheep are better grazers than most other herbivores. You can blame this on the philtrum, a groove separating the upper lip which lets the animals get very close to the ground when grazing.
  4. Female sheep are called ewes. They always form a strong bond with their young ones. They can easily recognise the bleating of a lamb that got lost because it wandered too far.
  5. Wild sheep are larger than their domesticated counterparts, the largest being 1.2 meters tall. Because they have to fend for themselves against predators, their horns are also longer.

Personality and Intelligence

  1. Sheep are very friendly. If you have ever encountered one, you know that, like dogs, they wag their tails. What you might not realise is the fact that they can form very strong bonds with other animals, not just fellow sheep but people and even goats.
  2. Sheep have good memories, hence their friendly nature. They can remember 50 different sheep. The same goes for humans, and that is the minimum number. They retain this memory for years. Science has determined that the process sheep use to remember isn’t that different from what has been seen in humans.
  3. When sheep fall sick, they treat themselves. They know the plants that they need to eat to cure their ailments.
  4. All this proves one thing: sheep are not stupid. That is the prevailing theory but it is false. Sheep are no different from cows in this arena. Science has proven that they can solve complex problems when challenged to do so.
  5. If you’ve ever seen sheep, you probably noticed that they are always together This trait is present in most sheep. As gregarious creatures, they prefer to operate in groups.
  6. There are over a billion sheep in the world and nearly a thousand species.

History and Culture

  1. Sheep meat is consumed by people in most countries around the world. The same goes for sheep milk. The Mongolians are interesting because they add sheep eyes to tomato juice to create hangover cures.
  2. The Egyptians did not necessarily worship sheep. But they considered them to be sacred creatures, which is why individual sheep were mummified like their human counterparts upon death.
  3. The ancient Sumerians, on the other hand, deified sheep.
  4. The Ancient Greeks would use the bones of sheep to make dice.
  5. The sheep industry has existed for at least ten thousand years ago.

Bonus Fact!

  1. The rumors are almost true. A sheep on its back can’t right itself, not without help. But this only applies to pregnant sheep or sheep with too much wool.

15 Curious Facts About Queen

Queen is one of the biggest bands in the history of rock music. It left an indelible mark on the world. If you have even the slightest interest in the music they made, not to mention its enduring legacy, these facts will fascinate you, especially if you’re not as knowledgeable about the band as you would like to be:

Origins

  1. Queen as a band was officially formed in 1970.
  2. Before joining Queen, Brian May and Roger Taylor were part of another band called ‘Smile’. Their lead singer was Tim Staffel, the man responsible for introducing his bandmates to Freddie Mercury. Staffel was never a member of Queen. But he played a critical role in the band’s formation. It was after he left and after he made all the necessary introduction that ‘Queen’ came into existence.
  3. The name change was Freddy’s idea. Precluding the gay connotations, Freddy believed that ‘Queen’ was a strong and regal name.
  4. Freddy’s birth name was Farrokh Bulsara. He adopted ‘Freddie’ during his stint at St. Peter’s School near Bombay. His passport said ‘Frederick Mercury’.

Music

  1. Queen initially experimented with a ruff rock sound. But they realised that they needed to be more attractive to the radio. So they changed their sound.

  5. Freddie Mercury had one of the most iconic voices in music history. But he was never as confident in his piano skills, which is why he always felt some trepidation whenever the band performed ‘Bohemian Rhapsody’.
  6. Thank God it’s Christmas, which Roger Taylor and Brian May wrote, is a highly popular track that, upon its release in 1984, spent six weeks on the Singles Chart in the UK. However, not only did the track not appear on any Queen album but they never shot a video for it. That doesn’t include its appearance on a ‘Greatest Hits’ EP in 2011.
  7. Queen has the longest-running fan club in rock history. The group was created in 1973 and its longevity is recognised by the Guinness World Book of Records.
  8. The band is responsible for the soundtrack of the ‘Flash Gordon’ movie from 1980.
  9. Brian May’s guitar is two hundred years old. He made it with the help of his father. The mantelpiece from which the guitar was built is two centuries old.
  10. Queen had no intention of releasing Another One Bites the Dust as a single. But then, Michael Jackson convinced them to do just that after a Los Angeles Concert.
