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.”

                                        10 Simple Morning Exercises That Will Make You Feel Great All Day

                                        10 Simple Morning Exercises That Will Make You Feel Great All Day

                                        There are lots of studies that show if you do some exercise in the morning, you will be in a better mood all day long. You will have more energy and you will certainly be a better colleague, friend or partner.

                                        One psychologist at Duke University has researched the effects of exercise on depressed patients and he has come to the conclusion that exercise has a definite role in treating this condition and has an important role in preventing people from relapsing.[1] According to the New York Times, scientists have now established that exercise also boosts your brain power.[2]

                                        In addition, there are studies from the Appalachian State University which show that blood pressure can be reduced by doing regular morning exercise.[3]

                                        Here are 10 simple morning exercises that will help you feel great the whole day long. You can include some of them in your morning exercise routine or do them all at home without having to enrol in a gym. Consult your doctor before starting any form of exercise routine if you are new to this.

                                        1. Cat Camel Stretch

                                        Stretching exercises are useful for muscle toning and also preventing arthritis. They can either be dynamic or static.

                                        Dynamic ones such as the cat camel stretch, are particularly useful for doing other exercises in the morning. They are also beneficial at other times of the day, especially after long periods of sedentary work. This one is great for spinal flexibility and is a good warm up exercise.

                                        Kneel down on all fours. Start by rounding your back just like a camel so that your head will try to meet your pelvis. This is the camel position. Then lower and lift your head so that your lower back is arched. This is the cat position. Do these movements slowly and smoothly. About 4 or 5 times.

                                        Here’s a video to guide you through:

                                        Advertising

                                        2. Go for a Walk or a Run

                                        This is better done outside so that you can connect with nature but running inside on a treadmill is almost as good. You can time yourself and increase length and time according to your fitness program.

                                        Always have new goals to reach. Start with brisk walking and work up to running. At my age, I am still walking!

                                        The health benefits are considerable. You can build stronger bones and you can help to maintain your weight.

                                        Also, you are helping your heart to stay healthy and keeping your blood pressure low.

                                        Learn more about the benefits of running here: 8 Benefits of Running 5 Minutes Every Day You Didn’t Know

                                        3. Jumping Jacks

                                        Michelle Obama is a great fan of this exercise and has become “Jumper in Chief.”[4] They are great for cardiovascular health and also for toning muscles especially the calves and the deltoids.

                                        Stand with feet together. Jump while spreading your arms and legs. Return to first position and keep going! You can start with doing these for 1 minute and then gradually build up to the number you are comfortable with. Here’s how:

                                        4. Abductor Side Lifts

                                        Watch the video below to see how to do this exercise. These muscles are important because you use them everyday to run, get into the car or onto and off a bicycle. They are very important also for your core stability and prevent the pelvis from tilting.[5]

                                        Advertising

                                        Do about 10 to 15 raises for each side like this:

                                        5. Balancing Table Pose

                                        This is a classic yoga pose. It benefits the spine, balance, memory and concentration.

                                        Start with the table pose (hands and knees). Breathe in before starting each movement. As you exhale, raise your left leg parallel to the floor as you raise the right arm, also parallel to the floor. Breathe in as you lower arm and leg. Repeat for the other side. 10 repetitions on each side is a good starting point.

                                        ablab

                                          6. Leg Squats

                                          Not just legs are involved but also hips and knees.

                                          Stand with your feet a bit further out from your hips. Arms are out in front of you. Then lower yourself as if you wanted to sit down until you reach a 90 degree angle. You can go down further if you want to. Then return to the starting position. Repeat 15 times for 2 sets for beginners.

                                          The benefits are that these exercises help with knee stability and can benefit the leg muscles such as quadriceps, hamstrings and calves.[6]

                                          7. Push Ups

                                          You start lying down (face down) but with your body held up at arm’s length. Your hands should be in line with your shoulders. Breathe in as you lower your body. That is fairly easy. Now, as you exhale, you have to get back up to the starting position.

                                          Advertising

                                          An easier version to start with is to bend your legs at the knees so you do not have to lift your whole body.

                                          Beginners may take up to a month to be able to do 100 push ups so you will have to start with a very small number and gradually increase it.

                                          This exercise is great for strengthening the chest, shoulders and the triceps. It is a great strengthening exercise for many muscle groups. In fact, most muscles from the toes to the shoulders are being used.

                                          8. Bicycle Crunches

                                          There are numerous crunch exercises targeting the abs. The bicycle crunch is a variation where you work more muscle groups. Aim for 15 to 20 reps to start off with.

                                          Watch the video to see how this is done correctly:

                                          9. Lunges

                                          Stand with feet shoulder width apart. Place your hand on your hips. Take one giant step forward with the right leg. Make sure the knee does not go too far forward, that is, past your toes. The left knee will go down to almost floor level. Alternate the legs as you go on.

                                          Try to do a set of between 8 and 12 reps for each leg. It is important to allow for a day of rest, so this exercise should be done on alternate days, especially if you are using weights.

                                          This exercise is great for strengthening and toning the quadriceps, glutes and hamstrings.

                                          10. Bicep Curls

                                          You can do this sitting down so if you spend a lot of time on the phone, this is a great exercise to do.

                                          Choose suitable dumbbells or another household object that you can easily hold. Sit down with the dumbbell in your hand. You need to sit forward a bit so that your triceps can lean on your thigh to give you support.

                                          Then bring the weighted arm up to shoulder length and then down again. Exhale as you lift the weight and inhale as you lower it.

                                          Here’re some important notes before you start doing this exercise:

                                          Try to do one or two sets of about ten repetitions for each arm and then switch arms.

                                          These exercises are really useful for toning the arm muscles.[7] In addition, they can strengthen and tone the brachioradialis muscle located in the forearm. These are the muscles we use to pick up things when we flex the arm at the elbow so we use these muscles countless times a day.

                                          You may have to build in a rest day for the heavier exercises, numbers 6–10. On the rest days, you can do gentler stretching exercises and also some walking or running.

                                          Morning exercise is not only a great mood booster, but will help you keep your weight down and also sleep better![8] Start including one or some of these exercises in your morning routine!
