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.”

                                        How to Get out of a Rut: 12 Useful Ways to Get Unstuck

                                        How to Get out of a Rut: 12 Useful Ways to Get Unstuck

                                        Have you gotten into a rut before? Or are you in a rut right now?

                                        You know you’re in a rut when you run out of ideas and inspiration. I personally see a rut as a productivity vacuum. It might very well be a reason why you aren’t getting results. Even as you spend more time on your work, you can’t seem to get anything constructive done. While I’m normally productive, I get into occasional ruts (especially when I’ve been working back-to-back without rest). During those times, I can spend an entire day in front of the computer and get nothing done. It can be quite frustrating.

                                        Over time, I have tried and found several methods that are helpful to pull me out of a rut. If you experience ruts too, whether as a working professional, a writer, a blogger, a student or other work, you will find these useful. Here are 12 of my personal tips to get out of ruts:

                                        1. Work on the small tasks.

                                        When you are in a rut, tackle it by starting small. Clear away your smaller tasks which have been piling up. Reply to your emails, organize your documents, declutter your work space, and reply to private messages.

                                        Whenever I finish doing that, I generate a positive momentum which I bring forward to my work.

                                        2. Take a break from your work desk.

                                        Get yourself away from your desk and go take a walk. Go to the washroom, walk around the office, go out and get a snack.

                                        Your mind is too bogged down and needs some airing. Sometimes I get new ideas right after I walk away from my computer.

                                        3. Upgrade yourself

                                        Take the down time to upgrade yourself. Go to a seminar. Read up on new materials (#7). Pick up a new language. Or any of the 42 ways here to improve yourself.

                                        The modern computer uses different typefaces because Steve Jobs dropped in on a calligraphy class back in college. How’s that for inspiration?

                                        4. Talk to a friend.

                                        Talk to someone and get your mind off work for a while.

                                        Talk about anything, from casual chatting to a deep conversation about something you really care about. You will be surprised at how the short encounter can be rejuvenating in its own way.

                                        5. Forget about trying to be perfect.

                                        If you are in a rut, the last thing you want to do is step on your own toes with perfectionist tendencies.

                                        Just start small. Do what you can, at your own pace. Let yourself make mistakes.

                                        Soon, a little trickle of inspiration will come. And then it’ll build up with more trickles. Before you know it, you have a whole stream of ideas.

                                        Advertising

                                        6. Paint a vision to work towards.

                                        If you are continuously getting in a rut with your work, maybe there’s no vision inspiring you to move forward.

                                        Think about why you are doing this, and what you are doing it for. What is the end vision in mind?

                                        Make it as vivid as possible. Make sure it’s a vision that inspires you and use that to trigger you to action.

                                        7. Read a book (or blog).

                                        The things we read are like food to our brain. If you are out of ideas, it’s time to feed your brain with great materials.

                                        Here’s a list of 40 books you can start off with. Stock your browser with only the feeds of high quality blogs, such as Lifehack.org, DumbLittleMan, Seth Godin’s Blog, Tim Ferris’ Blog, Zen Habits or The Personal Excellence Blog.

                                        Check out the best selling books; those are generally packed with great wisdom.

                                        8. Have a quick nap.

                                        If you are at home, take a quick nap for about 20-30 minutes. This clears up your mind and gives you a quick boost. Nothing quite like starting off on a fresh start after catching up on sleep.

                                        Advertising

                                        9. Remember why you are doing this.

                                        Sometimes we lose sight of why we do what we do, and after a while we become jaded. A quick refresher on why you even started on this project will help.

                                        What were you thinking when you thought of doing this? Retrace your thoughts back to that moment. Recall why you are doing this. Then reconnect with your muse.

                                        10. Find some competition.

                                        Nothing quite like healthy competition to spur us forward. If you are out of ideas, then check up on what people are doing in your space.

                                        Colleagues at work, competitors in the industry, competitors’ products and websites, networking conventions.. you get the drill.

                                        11. Go exercise.

                                        Since you are not making headway at work, might as well spend the time shaping yourself up.

                                        Sometimes we work so much that we neglect our health and fitness. Go jog, swim, cycle, whichever exercise you prefer.

                                        As you improve your physical health, your mental health will improve, too. The different facets of ourselves are all interlinked.

                                        Here’re 15 Tips to Restart the Exercise Habit (and How to Keep It).

                                        12. Take a good break.

                                        Ruts are usually signs that you have been working too long and too hard. It’s time to get a break.

                                        Beyond the quick tips above, arrange for a 1-day or 2-days of break from your work. Don’t check your (work) emails or do anything work-related. Relax and do your favorite activities. You will return to your work recharged and ready to start.

                                        Contrary to popular belief, the world will not end from taking a break from your work. In fact, you will be much more ready to make an impact after proper rest. My best ideas and inspiration always hit me whenever I’m away from my work.
