The solar system the milky-way is a four and a half billion year old creation that goes around the galactic center at around 200000 km per hour and goes fully around it once in every 250000000 years. The planets are split in to two groups with Mercury Venus Earth and Mars being terrestrial planets and Jupiter Saturn Uranus and Neptune being gas giants. Mercury is the smallest and lightest of all of our planets a mercury year is shorter than a day which leads to enormous rising and falling of the temprecher as well as it not being home to a moon or atmosphere. Venus is one of the brightest or lightest planets in our solar system and the hottest planet by a long margin. Having atmospheric pressure 92 time higher than earth.  Having an untameable greenhouse effect the lowest temprecher is 473 degrees. And like Mercury it also does not have a moon. Earth is the only planet with temprecher able to house humans and water and the only place with human intelligence. And has one moon. Mars is the smallest planet in our solar system other than Mercury.  And can only keep a very small atmosphere with 2 moons. It has the largest mountain in the solar system Olympus Mons being 3 times as tall as Mount Everest. Jupiter is the largest planet in our solar system and is made of hydrogen and helium and has the largest and most powerful storms in existence the largest bring the great red spot being 3 times as large as earth. It has the most moons in our solar system with 67 in total. Saturn is the second largest planet and gas giant in our solar system. As well as having the smallest density of all the planets. Also letting it swim/ float in water. It has rings and is the only planet in these 8 to have them and own 67 moons. Uranus is the smallest gas giant as well as the third largest planet. And is most probably the coldest but is axis is different to the other planets being tilted sideways. And it has 27 moons surrounding it. Neptune is similar to Uranus it is so far away from our main star the sun that 136 earth years is the equivalent to one Neptune year. 2100 km per hour is the highest wind speed on Neptune. As well as it having 14 moons. Mercury is smaller than one of Jupiter’s moons Ganymede. Jupiter alone has 70% of the mass of all of the other planets while Saturn has 20% Uranus has 4% and Neptune has 5% as for the terrestrial planets they contain only 1% all together. Jupiter can pull away dangerous planets or asteroids away from earth preventing us from any damage. But even so Jupiter is considered tiny compared to the sun it takes up 99.86% of the overall mass in our solar system. It mainly consists of hydrogen and helium only 2% is made up of heavier substances like oxygen and iron. At its core the sun combines 620 million tons of hydrogen per second and has plenty of energy to help human life. But trillions of asteroids and comets put in to two belts the asteroid belt between Mars and Jupiter and the Kuiper belt at the outside of our solar system. The objects size can range from a dust partial to a dwarf planet. The most known object in the asteroid belt is Ceres and the most well-known objects in the Kuiper belt are Pluto Makemake and Haumea. It is known as a dense collections of objects that constantly collide but they are so spared out that it is highly unlikely to see two asteroids at once making them quite empty but collisions are still quite common. The makes up four percent of our moons mass and the Kuiper belt is only between 1/25 and 1/10 of earths mass. One day in to the future of many millions of years the sun will die out and Mercury Venus and even earth may be destroyed in 5 hundred million years the temprecher will have increased until at some point in time it will melt earth’s crust. The sun will enlarge until it will either swallow earth or turn it in to lava. When the sun has lost most of its fuel as well as mass. It will shrink into a white dwarf and burn for a few billion years until it goes out forever like a candle and that means that life in the solar system will no longer be humanly possible. It will not even be noticed by the Milky Way though a small part of it has just gotten darker. Human life will either die out or go out in to the universe to find a new home. Why did only Mercury Venus and earth die out when the sun dies out is it because we are so close or that we rely on the sun? Who named all of the planets in our solar system was it the same person who discovered it and how long ago where they named? I now understand the true comparison of all the planets and objects in our solar system and  what each planet has or relies on  in our solar system to keep it in orbit.

It is an eight month journey for a robot curiosity to earths neighboring planet mars its shields had to withstand a 1600 degrees atmosphere as it landed on mars after they had to slow it down form 20 thousand km per hour to zero which took 7 minutes while moving to the perfect landing spot which they called the seven minutes of terror. Radio dishes in Camera Australia played a big part as they collected signals form curiosity as it landed.  Curiosity is not the first robot on mars but it is the biggest and the best equipped it can analyse rocks and has a drill for tacking samples and a laser. The aim is to learn more about what the red planet is made up off as well as signs of life because mars is most like earth in any of the planets in our solar system. It has an atmosphere and there are signs that their used to be water scientists believe that mars may have inhabited some form of life form in the past.  And they believe that in 35- 40 years there will be humans on mars thanks to Curiosity.I now understand the true difficulty of getting a robot on to another planet in our solar system and why they have done it and how it is helpful for the human race.I now also understand what Curiosity will be looking and searching for in the new planet and what things she has been equipped to do when helping us form a far off planet.When humans travel to mars how will they survive eight months on a space craft and how will they make the planet ready for humans and will robots set it up or will we?

This video was about the origins of astronomy and the people or cultures who have contributed over the years. Ancient Babylon was located near moden Baghdad they had their own form of writing which allowed them to create mathematical models of astrological research which for their time was quite  advanced, those models helped them to create a calendar. As well as being able to predict astrological phenomenon’s. It was the birthplace of moden horoscopic astrology. Maya a group of Mesoamerican Indians some of the records of their knowledge was burned so we now know very little but they used their knowledge to create the Mayan Long Count calendar which used a harder number system with the base of 20 instead of the 10 we use today. But it allowed them to predict the motions of the planets and other things like eclipses or a good time to start something. The Romans had the ancient Greeks who came up with the Ptolemaic system which believes that the earth was at the centre of the universe something that has since then has been proven wrong. A famous mathematician in ancient Greek and was believed to be the best astronomer of ancient times and the father of trigonometry. And they also had the precession of the equinoxes a term for the wobbling of Earth on its axis which helped prove that in about 12 thousand years the North Star will no longer be Polaris but will be begua. I now understand the all the different people cultures and countries who have contributed ideas models signs and languages to the astronomy that we know and so many love today. I now also understand that ancient astronomy of these cultures has changes so much over the many years that the original astronomy is almost lost because of the new generations have lost it. When making or putting together moden astronomy was there any culture that had more or less of an impact then others did?

Alerting situations like natural disasters can make your brain go to mush that is why is important for all families especially ones in natural disaster prone areas. This will make it less stressful if a natural disaster dose occur. When a natural disaster is coming your way have everyone in the family have some jobs to prevent issues occurring like filling the bath with water, taping windows, putting down sandbags and much more. In the presence of a natural disaster experts suggest that you don’t go on the roof, it is on some T.V shows but this is unsafe. They also say that if you can evacuate the area if not possible it is best to the bathroom where there is water for long amounts of time but it should not be your first resort. Is there anything that people can do during the process of a natural disaster? Should families keep food in the bathroom or is it unnecessary? I now understand the true thought of a plan for family’s to avoid the effects of a natural disaster and the many jobs and responsibilities.

Recent droughts in Cape Town have left a lot of people sad and unhappy calling the fourth of June day zero it is where they are suggesting that the town will have no more water for the citizens to live and survive off they have held it up April to May but they are not just running out of water but livestock and crops as well prices are going up. Each person has been given 50 liters a day which they have to go and get every day but it doesn’t get them far dishes and laundry is 18 liters, 90 second shower is 15 liters 1 toilet flush is 9 liters washing your hands 3 liters, cooking and drinking 2 liters each and dog bowl water 1 liter. If the drought continues citizens will only 25 liters of water a day and people are now questioning how it got this bad in 2014 the city’s water sources were at their full capacity now as the drought has starched on the supplies have reached their limits.  I now understand the true water each person receives and how it is ever so limiting and time consuming to a normal person’s day to day life. I also understand how worrying it is to the city if it does run out of suitable and drinkable water for its citizens. If the city dose run out of water will the citizens move to another city/country or stay in Cape Town, if so then where are they all most likely to go which city or county is most convenient for them to  go to?

Natural disasters can affect many people in many different ways like floods in Pakistan in South Asia where half a thousand people were killed and 20 million have been affected. This caused more trouble than the Tsunami that hit Asia in 2004 where 230 thousand people were killed from over 14 countries. Natural disasters can take away many core resources and separate people. They have rescuers who get all people near the affected area away. Then we need clean water and Water purification tablets so disease does not spread. They also need medical assistance to help anyone if they are sick or injured. As well as packaged food so they all keep healthy and it does not go off.  And they also need shelter so people are not affected by weather and so they have somewhere to go to. Local communities also rise funds so that they can buy resources and also rebuild what was destroyed and it is often hard because there is no power the recovery process can take several years but it builds community trust and is worth it in the end. What natural disaster has affected people the most? How many people does it take to rebuild a community? I now understand that the natural disaster is only part of the issue and that recovering properly is the hard bit and all the help that is needed to make this happen for the community.

Huge cracks coming up in a valley in the city of Kenya are leading to some scientists coming to the collusion that Africa may be splitting in to two by the crack are growing longer and deeper by the day and may be fully apart in over ten million years. It was first found after a lot of heavy rain over the past month which also caused hospital walls to collapse and roads and roads and towns to be flooded. The floods caused a split reaching serval km near Mai Mahiu ripping a highway open that sucked cars and farmer’s lands and homes. And it is now 15km deep and wide. It is said that in about 50 million years for the 2 tectonic plates to come apart. They predict this because it took about the same amount of time for Africa and South America to come apart from when they were together in Pangaea about 138 million years ago from now. Do they predict that this will happen to any other countries?  If the plated keep moving will they eventually crash in to each other? I now understand the true process of how tectonic plates spread apart and what happens to the earth and people living around it while this process is happening and the rough amount of time taken to do this.

Hawaiians are running from the volcano Kilauea volcano spews out lava ash and toxic gases on to the Hawaiian streets at a temperature of 1150 degrees and has destroyed 26 homes and spread 19km away from the volcano. This all started with a 6.9 magnitude earthquake on the volcanos south side on Friday. The biggest one since 1975 which caused a rise of sea level and rock slides.  Then the ground begun to split and caused lava coming up 70m in to the air. Most of the new activity is near the Leilani Estates and Lanipuna Gardens areas or towns of the Island of Hawaii. Kilauea is the most active of the five volcanoes on the island and in the world. It has been erupting constantly for 35 years. Most of the eruptions are a type called effusive eruptions meaning they flow continuously but not exploding and have been flowing in to our ocean. How long has this volcano had its grounds in Hawaii for? Has there been any other times in Hawaii or other countries where there has been a situation like this? I now understand the true devastation frustration and sadness of the Hawaiian citizens now that their homes schools parks and local areas are being destroyed by this large erupting volcano.

In a cyclone Darwin’s winds can reach 130km an hour. The cyclone left 23,000 homes without power the day after. 70 homes and one school where lost in a bushfire in Tathra on the NSW cost and a further 10 homes in Victoria which left 20,000 without power and took 280 aircrafts to put out.  Has Australia ever had higher winds than 130km an hour?  How long did it take for them to fully put out the bushfires?  I now understand the true effects of natural disasters.

The ring of fire is where the most natural can occur. Three quarters of the world’s volcanoes are in the ring of fire. 80% of the world’s earthquakes are in this ring to. I now understand the effects of these natural disasters. I also understand how lucky we are to be safe where we are. Do natural disasters link in to each other?
