20 Extraordinary And Inspiring Facts About The Universe

20 Extraordinary And Inspiring Facts About The Universe

The universe is so vast it’s extremely difficult to know the full extent of its complexities. Humans can only scratch at the surface of its immensity, but whenever we do we pick up remarkable information, and images, which are awe inspiring and baffling in equal measure. What we do know has been made readily available to the public thanks to the leading space exploratation organisations, so here are 20 of the most intriguing facts for your reading pleasure.

1. When you look into the night sky, you are looking back in time

    The stars we see in the night sky are very far away from us, so far the star light we see has taken a long time to travel across space to reach our eyes. This means whenever we look out into the night and gaze at stars we are actually experiencing how they looked in the past. For example, the bright star Vega is relatively close to us at 25 light-years away, so the light we see left the star 25 years ago; while Betelgeuse (pictured) in the constellation of Orion is 640 light-years away, so the light left the star around 1370, during the time of the Hundred Years’ War between England and France. Other stars we see are further away still, so we are seeing them much deeper in their past.

    2. The Hubble telescope allows us to look back billions of years into the past

      The Hubble Telescope enables us to look towards very distant objects in the universe. Thanks to this remarkable piece of engineering NASA has been able to create some incredible images, one of which is the Hubble Ultra Deep Field. Created using images from the telescope from 2003 and 2004, the incredible picture displays a tiny patch of the sky in immense detail; it contains 10,000 objects, most of them young galaxies, and acts as a portal back in time. In one picture we are transported 13 billion years into the past, just 400 to 800 million years after the Big Bang, which is early in terms of the universe’s history.

      3. You can watch the Big Bang on your television

        Cosmic background radiation is the afterglow and heat of the Big Bang, the momentous event that kick-started our universe 13.7 billion years ago. This cosmic echo exists throughout the universe, and amazingly we can use an old-fashioned television set to catch a glimpse of it. When a television is not tuned to a station you can see the black and white fuzz and clacking white noise, around 1% of this interference is made up cosmic background radiation – the afterglow of creation.

        4. There’s a giant cloud of alcohol in Sagittarius B

          Sagittarius B is a vast molecular cloud of gas and dust floating near the centre of the Milky Way, 26,000 light-years from Earth, 463,000,000,000 kilometres in diameter and, amazingly, it contains 10-billion-billion-billion litres of alcohol. The vinyl alcohol in the cloud is far from the most flavoursome tipple in the universe, but it is an important organic molecule which offers some clues how the first building blocks of life-forming substances are produced.

          5. There’s a planet-sized diamond in Centaurus named after a Beatles song

            Astronomers have discovered the largest known diamond in our galaxy, it’s a massive lump of crystallised diamond called BPM 37093, otherwise known as Lucy after The Beatles’ song Lucy in the Sky with Diamonds. Found 50 light-years away in the constellation of Centaurus, Lucy is about 25,000 miles across, so much larger then planet Earth, and weighs in at a massive 10 billion-trillion-trillion carats.

            6. It takes 225 million years for our Sun to travel round the galaxy

              Whilst the Earth and the other planets within our solar system orbit around the Sun, the Sun itself is orbiting around the centre of our galaxy, the Milky Way. It takes the Sun 225 million years to perform a complete circuit of the galaxy. The last time the Sun was in its current position in the galaxy the super-continent Pangaea was just about starting to break apart and early dinosaurs were making an appearance.

              7. Our solar system’s biggest mountain is on Mars

                Olympus Mons on Mars is the tallest mountain on any of the planets of the Solar System. The mountain is a gigantic shield volcano (similar to volcanoes found in the Haiiwain Islands) standing at 26 kilometres tall and sprawling 600 kilometres across. To put this into scale, this makes the mountain almost three times the height of Mount Everest.

                8. Uranus spins on its side, with some rather strange results

                  Most of the planets in the Solar System spin on an axis similar to the Sun’s; slight tilts in a planet’s axis causes seasons as different parts become slightly closer or further from the sun during their orbit. Uranus is an exceptional planet in many ways, not least because it spins almost completely on its side in relation to the Sun. This results in very long seasons – each pole gets around 42 Earth years of continuous summer sunlight, followed by a wintry 42-year period of darkness. Uranus’s northern hemisphere enjoyed its last summer solstice in 1944 and will see in the next winter solstice in 2028.

                  9. A year on Venus is shorter than its day

                  Advertising

                    Venus is the slowest rotating planet in our Solar System, so slow it takes longer to fully rotate than it does to complete its orbit. This means Venus has days that last longer than its years. It’s also home to one of the most inhospitable environments imaginable, with constant electronic storms, high CO2 readings, and it’s shrouded by clouds of sulfuric acid.

                    10. Neutron stars are the fastest spinning objects known in the universe

                      Neutron stars are thought to be the fastest spinning objects in the universe. Pulsars are a particular type of neutron star that emits a beam of radiation which can be observed as a pulse of light as the star spins. The rate of this pulse allows astronomers to measure the rotation.

                      The fastest spinning known pulsar is the catchily-titled PSR J1748-2446ad, which has an equator spinning at 24% the speed of light, which translates to over 70,000 kilometres per second. An artist’s impression of what this must look like is pictured above.

                      11. A spoonful of a neutron star weighs about a billion ton

                        Neutron stars spin incredibly quickly and are also incredibly dense. It is estimated, if you could collect a tablespoon of matter from the centre of a neutron star, it would weigh about one billion tons.

                        12. The Voyager 1 spacecraft is the most distant human-made object from Earth

                          The Voyager Program launched two spacecraft, Voyager 1 and Voyager 2, in 1977. The probes explored the planets and moons of the outer Solar System over several decades and are now continuing their mission to travel through the heliosphere at the edge of our Solar System and continue to voyage into interstellar space.

                          On March 20 2013, Voyager 1 became the first human-made object to leave the Solar Sytem and is now the furthest human-made object from Earth, currently 124.34 Astronomical Units away. In laymen terms, this means it’s around 1.15581251×1010 miles away. Putting it mildly this is a long way from home.

                          13. Voyager 1 captured the most distant photograph of Earth

                            In 1990, as part of the spacecraft’s ongoing mission, Voyager 1 turned its camera back on our home planet and took a picture. This became known as The Pale Blue Dot. Seen from 6 billion kilometres away, the Earth appears as a tiny blue speck in the depths of space. Astronomer Carl Sagan, who first suggested the idea of the photograph, noted, “From this distant vantage point, the Earth might not seem of any particular interest. But for us, it’s different. Consider again that dot. That’s here. That’s home. That’s us.”

                            14. Scientists are looking for evidence of extraterrestrial life on Earth

                              The Search for Extra-Terrestrial Intelligence (SETI) is a project to discover whether intelligent life exists elsewhere in the universe and how we may contact extraterrestrial species. The search includes looking for life on other planets and moons. For instance, some of Jupiter’s moons (such as Io) are promising places to look for evidence of primitive life, but the search for extraterrestrial life includes scientific research on Earth.

                              If scientists can disocver evidence life has generated independently more than once it would suggest life could occur in more than one place, for more than one time. For this reason scientists are searching for evidence that life could have happened more than once on earth, with intriguing prospects for the universe as a result.

                              15. It is estimated there are 400 billion stars in our galaxy

                                Our Sun is essential to us, the centre of our Solar System, and our source of light and energy, but it is just one of many, many stars that make up our home galaxy, the Milky Way. Current estimates suggest there are around 400 billion stars sharing our galaxy. The artist’s concept above shows what a a dust disk around a baby star could well look like.

                                16. There could be 500 million planets capable of supporting life in our galaxy

                                  Scientists searching for extraterrestrial life focus on “Goldilocks Planets“; these are planets which fall into a star’s habitable zone. Planet Earth seems to have exactly the right conditions for life to exist – its distance from the Sun means the temperature is right, water can exist as a liquid solid and a gas, and there are the right combination of chemical compounds available to build complex life forms. Other planets thought to have similar features are known as Goldilocks planets.

                                  Advertising

                                  In the Milky Way alone there are estimated to be 500 million potential Goldilocks planets, so if life can exist in places other than Earth there is a huge number of potential planets on which it might thrive. If these numbers are applied to all the galaxies in the universe there could be a staggering variety of planets capable of supporting life. Of course, we have no evidence life exists elsewhere, but if it does there are plenty of places for it to set up home.

                                   17. There are probably more than 170 billion galaxies in the observable universe

                                    Different calculations provide different numbers for how many galaxies there are in the observable universe – that is the part of the universe we can see from Earth with our current technology, there maybe many more but they are simply to far away for our telescopes to detect. Using data from the Hubble Telescope astronomers have calculated there are likely to be around 170 billion galaxies in the observable universe.

                                    18. There could be an infinite number of universes

                                      This is more speculative theory than a fact, but several branches of mathematics, quantum mechanics, and astrophysics have all come to similar conclusions: our universe is just one of many and we actually exist in a ‘multiverse’.

                                      There are different ideas of how this could be, one being the concept of atoms only capable of being arranged in a finite number of ways in time and space, ultimately leading to the repititon of events and people. Other theories propose bubble or parallel universes and ‘braneworlds’ that hover just out of reach of the dimensions we experience. Although these concepts seem like the far-fetched ideas of science-fiction, they are actually proving to be the most elegant solutions to problems thrown up by our discoveries of how the universe works.

                                      19. The human brain is the most complex object in the known universe

                                      Our brains are remarkably complex objects with a hundred billion neurons, a quadrillion connections, and we still know very little about how this organic super computer operates. But we do know the human brain is the most complicated thing we have yet discovered. It gives us the power to form language and culture, consciousness, the idea of self, the ability to learn, and understand the universe and reflect on our place within it. We even have an inbuilt “model of gravity“, which is pretty useful.

                                       20. We are all made of stardust

                                        This may sound fanciful, but the reality is almost every element found on Earth was created in the burning core of a star, all the stuff that makes up life on Earth, therefore our bodies are made from stardust. NASA have studied stardust extensively, and you can read more about their research on their official website. A NASA stardust canister is pictured above.

                                        In the words of Carl Sagan, “The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.”

                                        12 Best Brain Foods that Improve Memory

                                        12 Best Brain Foods that Improve Memory

                                        Nutrition plays a vital role in brain function and staying sharp into the golden years. Personally, my husband is going through medical school, which is like a daily mental marathon. Like any good wife, I am always looking for things that will boost his memory fortitude so he does his best in school.

                                        But you don’t have to be a med student to appreciate better brainiac brilliance. If you combine certain foods with good hydration, proper sleep and exercise, you may just rival Einstein and have a great memory in no time.

                                        I’m going to reveal the list of foods coming out of the kitchen that can improve your memory and make you smarter.

                                        Here are 12 best brain foods that improve memory:

                                        1. Nuts

                                        The American Journal of Epidemiology published a study linking higher intakes of vitamin E with the prevention on cognitive decline.[1]

                                        Nuts like walnuts and almonds (along with other great foods like avocados) are a great source of vitamin E.

                                        Cashews and sunflower seeds also contain an amino acid that reduces stress by boosting serotonin levels.

                                        Walnuts even resemble the brain, just in case you forget the correlation, and are a great source of omega 3 fatty acids, which also improve your mental magnitude.

                                        Advertising

                                        2. Blueberries

                                        Shown in studies at Tuffs University to benefit both short-term memory and coordination, blueberries pack quite a punch in a tiny blue package.[2]

                                        When compared to other fruits and veggies, blueberries were found to have the highest amount of antioxidants (especially flavonoids), but strawberries, raspberries, and blackberries are also full of brain benefits.

                                        3. Tomatoes

                                        Tomatoes are packed full of the antioxidant lycopene, which has shown to help protect against free-radical damage most notably seen in dementia patients.

                                        4. Broccoli

                                        While all green veggies are important and rich in antioxidants and vitamin C, broccoli is a superfood even among these healthy choices.

                                        Since your brain uses so much fuel (it’s only 3% of your body weight but uses up to 17% of your energy), it is more vulnerable to free-radical damage and antioxidants help eliminate this threat.

                                        Broccoli is packed full of antioxidants, is well-known as a powerful cancer fighter and is also full of vitamin K, which is known to enhance cognitive function.

                                        5. Foods Rich in Essential Fatty Acids

                                        Your brain is the fattest organ (not counting the skin) in the human body, and is composed of 60% fat. That means that your brain needs essential fatty acids like DHA and EPA to repair and build up synapses associated with memory.

                                        The body does not naturally produce essential fatty acids so we must get them in our diet.

                                        Advertising

                                        Eggs, flax, and oily fish like salmon, sardines, mackerel and herring are great natural sources of these powerful fatty acids. Eggs also contain choline, which is a necessary building block for the neurotransmitter acetylcholine, to help you recall information and concentrate.

                                        6. Soy

                                        Soy, along with many other whole foods mentioned here, are full of proteins that trigger neurotransmitters associated with memory.

                                        Soy protein isolate is a concentrated form of the protein that can be found in powder, liquid, or supplement form.

                                        Soy is valuable for improving memory and mental flexibility, so pour soy milk over your cereal and enjoy the benefits.

                                        7. Dark chocolate

                                        When it comes to chocolate, the darker the better. Try to aim for at least 70% cocoa. This yummy desert is rich in flavanol antioxidants which increase blood flow to the brain and shield brain cells from aging.

                                        Take a look at this article if you want to know more benefits of dark chocolate:

                                        15 Surprising and Science-Backed Health Effects of Dark Chocolate

                                        8. Foods Rich in Vitamins: B vitamins, Folic Acid, Iron

                                        Some great foods to obtain brain-boosting B vitamins, folic acid and iron are kale, chard, spinach and other dark leafy greens.

                                        Advertising

                                        B6, B12 and folic acid can reduce levels of homocysteine in the blood. Homocysteine increases are found in patients with cognitive impairment like Alzheimer’s, and high risk of stroke.

                                        Studies showed when a group of elderly patients with mild cognitive impairment were given high doses of B6, B12, and folic acid, there was significant reduction in brain shrinkage compared to a similar placebo group.[3]

                                        Other sources of B vitamins are liver, eggs, soybeans, lentils and green beans. Iron also helps accelerate brain function by carrying oxygen. If your brain doesn’t get enough oxygen, it can slow down and people can experience difficulty concentrating, diminished intellect, and a shorter attention span.

                                        To get more iron in your diet, eat lean meats, beans, and iron-fortified cereals. Vitamin C helps in iron absorption, so don’t forget the fruits!

                                        9. Foods Rich in Zinc

                                        Zinc has constantly demonstrated its importance as a powerful nutrient in memory building and thinking. This mineral regulates communications between neurons and the hippocampus.

                                        Zinc is deposited within nerve cells, with the highest concentrations found in the hippocampus, the part of the brain responsible for higher learning function and memory.

                                        Some great sources of zinc are pumpkin seeds, liver, nuts, and peas.

                                        10. Gingko biloba

                                        This herb has been utilized for centuries in eastern culture and is best known for its memory boosting brawn.

                                        Advertising

                                        It can increase blood flow in the brain by dilating vessels, increasing oxygen supply and removing free radicals.

                                        However, don’t expect results overnight: this may take a few weeks to build up in your system before you see improvements.

                                        11. Green and black tea

                                        Studies have shown that both green and black tea prevent the breakdown of acetylcholine—a key chemical involved in memory and lacking in Alzheimer’s patients.

                                        Both teas appear to have the same affect on Alzheimer’s disease as many drugs utilized to combat the illness, but green tea wins out as its affects last a full week versus black tea which only lasts the day.
