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 Benefits of Meditation That Improve Your Body And Mind

                                        12 Benefits of Meditation That Improve Your Body And Mind

                                        As a mediation teacher, I am constantly confronted with these two questions regarding the benefits of meditation:

                                        1. Why can’t I enjoy the benefits of meditation continuously?

                                        I ask back: Is it maybe because you see mediation as a technique, performance, or some exclusive activity? The answer is: yes!

                                        Or, because your mind is constantly evolving on the past negative attachments and traditional habits? After careful thinking they answer: yes, probably!

                                        Although meditation is very simple and challenging at the same time, in the above mentioned case, it’s not easy to benefit from meditation, especially when approached with the idea that it has to be learned, studied, or applied. Meditation is to be seen as a natural, mental cleansing process that happens on a basis of awareness on a moment-to-moment experience. When that takes place, the benefits of meditation are continuous.

                                        2. What is the purpose of meditation?

                                        The purpose of meditation is to accomplish a level of consciousness for mastering the mind and uniting with the finest, deepest, and subtlest part of yourself as a being.

                                        It is a conscious process of observation of the mind—helping the meditator to understand the structure of its mind and the quality of its content. During this process, countless benefits of a physical, mental, and spiritual/philosophical nature arise for the meditator.

                                        Meditation as a Fixer and Benefactor

                                        In this article we’ll have a look at the primary and the ultimate benefits of mediation, which improve your body and mind at the same time. For the sake of clarity, readability, and tangible experience, I have separated the benefits into three groups.

                                        You can change just about anything you don’t like about yourself (psychologically, as well as physically) through meditation. However, this is only possible with a specific approach, when your brain allows the benefits of meditation to do their work.

                                        This means not to interrupt the benefit with other thoughts, but to let their effect implement itself in your body and mind. This approach is crucial.

                                        The following exercises will make you feel the benefits of meditation instantly, but the continuity of the benefits of meditation on your body and mind depend on the discipline of your brain, how you manage external stimuli and your thoughts.

                                        Less Physical, More Psychological

                                        Even though the practice of meditation is more psychological and less physical, the first benefit we’re going to experience is both physical as well as mental.

                                        This benefit happens literally immediately, right at the moment of meditation. It is the essence of mediation basically.

                                        The First Benefit of Meditation

                                        The first benefit of meditation is twofold:

                                        1. Improving inward attention (sharpening the mind)
                                        2. Relaxation of the body

                                        Let’s do it right now. This benefit consists of only one step, and it is very simple to perform. It goes like this:

                                        Advertising

                                        Sit still and pay attention to your exhalation.

                                        That’s it! Technically, the whole journey into the world of mediation begins here and nowhere else. And right here, you benefit from this step in the following way:

                                        When you pay attention to the flow of your exhalation (gentle, deep, effortless exhalation), your body begins with the process of relaxation instantly (your heart rate slows down, your nervous system calms, and tension in your muscles is relieved).

                                        When the nervous system calms, your mind calms down, and, more specifically, less thoughts are produced by your mind. How, exactly? By applying one of the most valuable mental skills—attention—the mind follows the breathing and has no space and time to generate any other thoughts. Only when the attention goes off the breath, other thoughts are constructed, and the mind is accelerating with thought production again.

                                        Keeping the First Benefit Effective and Ongoing

                                        Here you apply the approach of not letting the relaxation and attention process get interrupted; rather let the effects of these benefits implant in your body and mind as deeply as possible.

                                        This is to say, the instant relaxation and inward attention happen at the same time when you follow the flow of your breath. Repeating this process—creating a constant rhythm out of the breathing and the attention—you create a process of meditation.

                                        Keep your attention on the flow of your breath and see how the calmness of body and mind begin to rule your present moment. The longer you stay connected to your breathing, the stronger you’ll feel the benefit. Start with 3-5 minutes at a time without doing anything else, and increase to 10-20 minutes and onwards.

                                        Can you think of a better, simpler and quicker exercise that can relax the body and improve attention in this way, at this speed?

                                        Advertising

                                        This benefit takes you to the second one.

                                        The Second Benefit of Meditation

                                        While still working with the first benefit of mediation, you slowly start to see the second benefit of mediation, which is fourfold. I call it the major value of mediation:

                                        1. Energy (physical and mental strength)
                                        2. Observance
                                        3. Peacefulness (stillness, and space of mind for deeper observation)
                                        4. Patience

                                        Peacefulness is the source of a blissful life. The energy is the fuel to express that blissfulness. Whatever we want to accomplish in life we need: 1) Physical and mental strength, 2) Observance of that energy, 3) Peacefulness—the calmness and stillness that creates space for freedom of being and creative thinking, and 4) Patience for the process of accomplishment.

                                        You can only get creative in thinking and boosted with physical and mental energy when you get in touch with the deepest levels of yourself—when you harmonize your mental and physiological activities. How do you do that? Let’s try it right now:

                                        This step involves the observation of the two separate movements of your breath. After paying attention on your exhalation, you have prepared your body and mind to really see and feel what true peacefulness and true energy means.

                                        1. Energy

                                        Keep your attention on your inhalation (inhaling gently, deeply and lightly) and feel the new energy (new oxygen) flowing in your body. The inhalation is the symbol for aliveness and vitality. It is the the primary act that connects the baby’s body with the outside world after coming out of the womb[1]. Each inhalation is a new opportunity for your body to revive, regenerate, and renew itself.

                                        2. Observance

                                        The observance comes during the process of meditation, enabling you to see the physiological benefits of introducing new energy to your body. Use that benefit by utilizing its effects, and create deeper observation into yourself. With every single inhalation, this observation will enable you to generate even more energy, mentally and physically.

                                        3. Peacefulness

                                        Keep your attention on your exhalation, and feel how, out of the relaxation, peacefulness is spreading throughout your whole body. The exhalation is the symbol for relaxation and peacefulness. Only through meditation can you realize what absolute peacefulness means.

                                        The meditation delivers the previous benefits to you immediately and opens up the possibility for many other benefits and great virtues.

                                        The Ultimate Benefits of Meditation

                                        Patience is a key quality when it comes to the ultimate benefits of meditation.

                                        Since the mind is the tool that reveals everything, mediation is the method for the proper utility of the tool.

                                        The above mentioned benefits of mediation lead to the ultimate benefits of mediation—qualities that depict what makes a human being human. As you dwell in a meditative state of being, the following benefits begin to emanate:

                                        • Diligence: the persistence for righteous effort to reach an intrinsic value; inner strength.
                                        • Temperance: to express self-control and show excellence in managing the physio-biological and mental necessities
                                        • Courage: using righteous effort and braveness to look into the weaknesses of yourself and at the hardship of your life, endure it and patiently overcome the obstacles
                                        • Loving kindness and Compassion – a capacity to care, understand, and tolerate other people’s state of being, wishing them freedom from suffering.
                                        • Wisdom: the moment when you feel that mediation gives you the feeling and the knowledge that what you do relating to life and practical affairs is just.
                                        • Equanimity: that puts you in a state of composure, and you experience an ongoing blissful state of being.

                                        These are the 6 ultimate benefits of meditation that put your body and mind in a state of health and balance.

                                        Final Thoughts

                                        Mediation exists to put order in your mind and awaken the best of you, to reconnect you to your goodness and your inborn intelligent capabilities.

                                        Meditation is the window to your true Self. It gives you a panoramic view of your heart’s greatness. It shows you the true meaning of love, freeing you from the dungeons of ignorance and despair. The power of meditation dismantles the evil that’s trying to cloud the beauty of your heart.

                                        Your heart, body, and soul are the bridge over which the challenges of life frequently carry their heavy load. Meditation is the support of that bridge. Make use of that support.
