Interesting Facts about The Milky Way

The Milky Way is our home galaxy. It began to form twelve billion years ago. The Milky Way galaxy is a part of fifty galaxies that is referred as the local group. Moreover, the local galaxy group itself comes under a large group of galaxies. The larger group is referred as Virgo Supercluster. The Milky Way galaxy is a barred spiral galaxy with one spur and four arms in its diskette and recently a new outer arm was discovered. The mass of the Milky Way galaxy is four hundred to eight hundred billion solar masses. It contains at least four hundred billion stars. It comes under a local group.

It is estimated that Milky Way galaxy will smash together with Andromeda galaxy. The astronomers have estimated five billion years for the chances of collision. Some astronomers mention as a binary system. The dust, gas, and stars of Milky Way galaxy orbit in the centre. They orbit at a speed rate of two hundred kilometres per second.

The Black Hole
There is a super massive black hole in the centre core of the Milky Way galaxy. The black hole is referred as Sagittarius A. It is said that Sagittarius A has the mass of 2.6 million stars. The Milky Way galaxy grows by merging and joining with other galaxies in the universe through the time. It is gulping up substance from Magellanic Clouds. Sagittarius Dwarf Spheroidal is a small galaxy and Milky Way galaxy is currently getting stars from that galaxy. The Sagittarius Dwarf Spheroidal is actually small in size.

Our Planetary System: The Sun

The centre part of the solar system is occupied by Sol or Sun. It is completely responsible for the weather and climate of the Earth. It is actually a perfect sphere and has a difference of about ten kilometres in diameter among the equator and the poles. The standard radius of our Sun is 695,508 km, out of which twenty to twenty five percent is the core. The age of the Sun is 4.6 billion years. It comes under yellow dwarf type. The mass of the Sun is 333,060 times the Earth. The surface temperate of the Sun is 5500 degree Celsius.

It is said that one million Earth has chance to accommodate the Sun. If the hollow Sun could accommodate spherical Earths, then it could hold around 960,000 Earths inside. The surface area of the Sun is 11,990 times compared to the Earth. There are chances for the Sun to consume the Earth. If all the hydrogen is burnt, the Sun will burn helium for another one hundred and thirty million years. During that point, it will start to expand and engulf the Earth, the Venus, and the Mercury. In that stage, the Sun will become a red fat giant.

At one point, the Sun has chances to get back to the size of our Earth. When it crosses the red giant stage, the Sun will tend to collapse, and retains its enormous mass. It will contain the equal or appropriate volume of our Earth. When this situation occurs, the Sun will be referred as a white dwarf. It contains 99.86% of mass present in the whole solar system. It contains three quarters of Hydrogen, and the remaining is Helium. It takes about eight minutes for the Sun light to reach our Earth considering the distance between the Earth and the Sun.

How Do They Do Cleaning in Outer Space?

How Do They Do Cleaning in Outer SpaceHow do they do cleaning in outer space? Anyone that has a vested interest in space has probably wondered about this question several times. After all, just because there is no gravity in space doesn’t mean that things don’t get dirty, especially when human beings are in the area stirring up dust and adding garbage that must then be cleaned up.

If you look at individuals that are on the space station, you will realize that they clean in much the same way that a person would clean their house. They use liquid detergent which they dilute and  spray using the best pressure washers UK homeowners love to use on surfaces such as walls, floors or areas where meals are eaten and they wipe the detergent off with a cloth. Most of the time, they use disposable gloves while doing so in order to ensure the cleanest environment possible. They also use a vacuum cleaner to get rid of dust and other irritants that are in the area.

Of course, there is always the problem associated with garbage. Unfortunately, garbage seems to be one of those things that multiplies all by itself any time humans are present, regardless of the location. Space is really no different. Astronauts on the space station create garbage but it cannot be disposed of in space. Instead, they collect the garbage daily and put it in a receptacle where the garbage is then brought back to earth when they return. After that has occurred, the garbage is disposed of in much the same fashion as it would be for anyone here on Earth.

Astronauts also change filters located in air purification systems. Because they are breathing the same air for months on end, this is probably one of the most important things they do and it is not something that can be overlooked. The good news is that as long as everyone keeps up with their duties, it really doesn’t take that long to ensure that the space station remains clean and that no additional garbage or debris is introduced into space itself.

How Do Astronauts Cook Food In Outer Space?

How Do Astronauts Cook Food In Outer Space1That is an interesting question for a couple of reasons. One, on a default it would tell us what astronauts eat in space. Secondly, it would address the question of how is the lack of gravity dealt with such that things would actually stay put. How gravity makes us interact is not something we would think about until faced with the lack of it.

Cooking in space takes a lot of trial and error as well as duct tape and plastic bags. Don’t expect to find one to the top 10 gas ranges up on a space station though because for safety reasons, the most that astronauts have to work with is a microwave. LPG gas tanks simple won’t survive the atmospheric pressure up in space.

Going back to how astronauts “cook” in space… The ground likes to send things in plastic bags upward. The duct tape goes on the table sticky side up to help keep things in place. This does get messy but once enough stuff is on the tape, it is simple to throw it away and open another strip. To cut things use a plastic bag held down by duct tape as a cutting board. It is important not to cut food into too small of pieces. The reason is it is difficult to get them off of your hand due to the lack of gravity. So they are going to have to be brushed off your hand directly into a bag. It can also be helpful to cut within the bag the food is being stored in, but you would need to be extremely careful not to cut the bag in the process.

Another thing to be aware of with food is…the food needs to not be too dry in order to be transferred when it is done. In order to remedy this, foods that are normally served dry, such as scrambled eggs, need sauce added to them. A final thing that may not be so obvious is: there is a lot of trash involved at every stage of cooking in space. Unlike when on the ground, it needs to be cleaned up immediately because of the lack of gravity. It would also be safe to assume that when cooking in space, a lot of disinfectant wipes are gone thru as well.

A final interesting tidbit that would be obvious if you thought about it…spices such as salt and pepper are only available in liquid form. If they were there in solid form, they would just float away. This could result in getting in someone’s eyes or just as bad damaging vents.

Will Drones Soon Be Carrying People in the Skies?

Could drones soon be carrying people in the skies? The reality of the situation is that drones are currently not large enough to carry people, but there is every possibility that this will change in the near future. Drones fly in much the same way that model airplanes fly so there is every chance that a larger drone can be built that is capable of carrying passengers. If you really think about it, larger drones have been in use for years by certain military organizations, carrying out complex military missions while being controlled from some far-off location. The technology is definitely there and it has been proven for a number of years now. All that is required is for someone to build a drone that is large enough to accommodate passengers and then ensure that it is safe enough for people to fly on.

While this is probably not something that will happen tomorrow, it is almost inevitable that it will eventually happen to the point that manned aircraft might cease to exist at some point. For some individuals, such as those that pilot large commercial Jets, this realization is not that far off. For several years, these jets have been largely controlled by electronics. Even though they still have a full flight crew on board, it is not at all uncommon for the flight crew to merely sit in the cockpit and monitor the electronics in order to ensure that everything is going according to plan. It is almost unheard of for a commercial airliner to be controlled by an individual in this day and age. They are all almost always controlled by the on board computer and the pilot is actually more like a glorified passenger at this point.

The same is true, at least in a certain sense, even for military aircraft. They have specialized onboard computers known as fly-by-wire systems that make them controllable. Without these sophisticated systems, the pilot would be unable to control the aircraft for any length of time. All of this has proven that the technology does indeed exist and that it is possible for a computer to stabilize an aircraft effectively, especially if someone is actually on the ground and flying the drone from a remote location. In reality, the possibilities associated with drones are endless. Eventually, they can be used to transport passengers, cargo and virtually anything else that can be thought of over vast distances, essentially making the traditional airplane nothing more than a museum relic.

The idea that people could sometimes board a drone that is otherwise unmanned and fly on it is rather disconcerting for many individuals. They like to think that there is someone in charge of the aircraft they are flying on. For others, it is a natural progression of technology and something that rather excites them. One thing is certain, this is a type of technology that is progressing rapidly. Therefore, there is every indication that drones will eventually carry passengers in the skies. It is even likely that it will become the main form of transportation and that traditional forms of air travel will eventually become things of the distant past.

Are hoverboards finally a reality with self-balancing scooters?

Outtop Two WheelsEver since Marty McFly got his hands on a hoverboard in ‘Back to the Future’ people have been desperately waiting for this futuristic dream to become a reality. Earlier this year a product stormed the market which claimed to have finally realised this dream. The self-balancing scooter is a hybrid of the Segway and a traditional skateboard that is battery powered and works by responding the user’s instructions by recognising their balance. The product itself does look extremely similar to the hoverboard seen in the cult movie. However, there is one key difference, the real life ‘hoverboard’ has wheels! Surely that alone shows that it’s not actually a hoverboard at all because it uses wheels to roll across the floor, but many users would disagree.

Are self-balancing scooters hoverboards?

Pretty much as soon as the self-balancing scooters came on to the market people were renaming them as hoverboards as this trend has not stated within the realms of the general public as many celebrity users have also picked up on the name. One of the main reasons that they are considered to be hoverboards is obviously to do with how the products look, as they look almost identical to the hoverboard seen in ‘Back to the Future’ only with wheels added. Another reason is to do with the feel of the scooters. Although the scooter itself is technically touching the floor, the rider isn’t. By standing on the top of the scooter the rider will get the feeling of hovering above the ground as they are moving along. So even though, the scooter is technically rolling, the idea that it hovers is demonstrated by how it feels to ride it.

However, it is important to look at the technical aspects of the scooter as well as the way it feels to ride. The pure facts of the matter are that because the scooter works using wheels that roll across the floor it doesn’t actually hover at all and therefore shouldn’t be considered a hoverboard. Even the best self balancing scooters don’t quite live up to it but if you are wanting to purchase one then you should read some reviews first.

Will hoverboards ever be a reality?

As much as self-balancing scooters may give the illusion of a hoverboard experience, they are still technically not hoverboards. So will there ever be an opportunity to fully float above the ground? Apparently there might be. A technology company is rumoured to have created a real life hoverboard which will be available to purchase in the next couple of years. The innovative design uses magnetic technology which means that it can only be used on top of a pre-prepared metal surface. The cost of doing this as well as the cost of the hoverboard itself which is thought to be an eye watering $10,000 dollars will definitely set you back a few bob. However, if you’ve got the cash it might be worth it to get the real ‘Back to the Future Experience’. However, for now we can content ourselves with the knowledge that we have something that is almost as good as the real thing. The induction of the self-balancing scooter was a surprise for most general consumers, as that sort of technology was thought to be pretty far off. There is no denying that it is hugely exciting and fun, and the fact that it has been given to the masses in the same year as Mr McFly himself had his first hoverboard experience is a pretty monumental event. Even if they have wheels, only sit a few inches across the ground and rarely go faster than 6mph, they have well and truly brought us into the future, and surely the developments will only continue.



Why stargazers turn to coffee during long sessions

coffee-star-gazing

Coffee has a long list of benefits, but mostly coffee is known to us for it’s an excellent energy boosting capacity.

Practically, we all consume coffee mostly we like it and when we need to get that extra energy to keep us going especially during the sleepless night. Many people have fancy coffee makers in their homes but it’s good to read reviews first to find the best machine.

The reason behind that is nothing rocket science rather than very simple. Coffee contains a specialized substance known as caffeine which is said to the most popular psychoactive substance consumption wise.

Now, although we all are used to consume coffee perhaps more so in our workplace/office rather than in our home, but stargrazers are known to have a special affinity for coffee as well as caffeine.

But, before we jump into any conclusion, let us know a bit about the stargazers. Stargazers, a popular and more common name to what we officially call observational astronomers.

They are the professionals who observes the sky to be put in a simple way.

There are a lot of complexities, meetings and long sessions involved in the day to day work of the stargazers and the long sessions as it is aptly named continues for long, really long.

So let us look some of the reasons why stargazers turn to coffee during long sessions.

  1. Caffeine as we all know is a great energy booster and an excellent psych activator which helps the stargazers keep going in their long sessions and help them to cope with their sleeplessness and provides them with that extra kick in the form of that extra energy.
  2. Caffeine (which is the key ingredient of coffee) is said to block the inhibitory neurotransmitters from travelling and affecting our brains which eventually lead to having feel more energized, improved mood, and ability to cope with and get going without being able to sleep for a while.
  1. Another benefit for which stargazers use coffee extensively is that it readily gets absorbed into one’s bloodstream right after the consumption which helps to prevent any sort of hangover kind of things, side effects and all that, which is very much essential for stargazers as they need to observes stars with real concentration and diligence.
  1. It also acts as an excellent stimulating agent.

Besides, coffee or caffeine also has its fair share of benefits which are not typically exclusively beneficial only for the stargazers but for all of as a whole.

  1. Regular consumption of coffee in a regulated manners helps one to keep various diseases at bay like – diabetes, cholesterol related problems, it also considerably lowers the risks of heart diseases.
  1. It also eliminates to a large extent the risks of stroke and heart attack besides lowering the risk of other heart related diseases as mentioned earlier.
  1. Studies have shown that high intake of coffee reduces risk of cancer especially liver cancer.
  1. Caffeine intake are said to protect us to some extent from Alzheimer’s disease and Parkinson’s disease.
  1. But, apart from all these benefits, all of us specially the stargazers must keep in mind not to overdo the intake of caffeine as coffee consumption more than the permitted limit can cause nausea, heartburn or make these existing conditions much more worse.

Frequent necessity of urinating can be another side effect of high caffeine intake, which is one thing for sure the stargazers don’t want to get into. So, it is advisable that coffee gives you many reasons to turn to coffee, but always be careful to not overdo it.

 

 



Insights Into Different Kinds of Galaxies

There are three types of galaxies. It is developed by Edwin P. Hubble. The classification scheme is improved by famous astronomer Gerard de Vaucouleurs. They have divided into three types based on their size, extent of bars, an openness of spirals and size of the galactic bulges.

Spiral galaxies: It is the most common kind in the universe. Andromeda galaxy is located nearby our Milky Way galaxy. Milky Way galaxy comes under spiral type. The spiral consists of large rotating diskettes of nebulae and stars. Moreover, the spiral is completely covered by a shield of dark matter. The galactic bulge is the central bright area. It is located in the centre of the galaxy. Most spirals have an aura of star clusters and stars arranged below and above the disk. The barred spirals are those that have bright and large bars of stars. It will have a material that divides their central sections. The astronomers study about the majority of galaxies with these bars. They study to understand their functions and role they play in the galaxy.

Elliptical galaxies: It is egg shaped that is ovoid or ellipsoidal. It is mostly found in smaller compact groups and galaxy clusters. Mostly, elliptical consists of low mass and older stars. Do you know why? It is because the elliptical does not have dust clouds and star making gas. At present, there is a small star formation is seen in them. Ellipticals have about one hundred million to one hundred trillion stars. It occurs in different sizes and different numbers. One of the best examples to explain Elliptical galaxy is Messier 87.

Irregular Galaxies: As the name implies, the galaxy is irregular in shape. Small Magellanic Cloud is the best example for an irregular galaxy. It can be viewed from Earth. It does not have an appropriate structure to shape itself as elliptical or spiral.

Facts About the Asteroid Belt

solar-system

A majority of asteroids is easily found beyond the Mars. The Asteroid belt is formed when they join. Hygiea, Pallas, Vesta, and Ceres are the four largest asteroids. Due to gravitational interactions, some asteroids orbit to nearby Earth space and some migrate or move away from the solar system. The four large asteroids contain more than half the mass. The remaining mass is constituted by myriad smaller bodies. Once a theory was stated regarding the asteroid belt. As per the same, if asteroids are combined, then it can make up a missing planet ‘fifth rocky planet’.

Do you know the location of the asteroid belt? It is located in the space between the Jupiter and Mars. The place is said to be located at the distance of 2.2 and 3.2 AU (astronomical units) from the Sun. The asteroid belt is about one astronomical unit thick. In an average, the distance between objects is quite large. When you stand on the asteroid belt and see the other one, you will find the other one at a far distance place. The objects of the asteroid belt are made up of stone and rock. Some of the objects are solid objects, and most of them consist of orbiting rubble piles.

There are billions of asteroids in the asteroid belt. Some of the asteroids remain large in size. But there are also asteroids in a small pebble like sizes. It is said that there should be at least known 7000 asteroids. The discoverers suggest names to the asteroids, and they also give a number to the found asteroids. There are chances for the asteroids to move away from the belt due to the gravitational influences. The asteroid belt can also be referred as the main belt. It remains unique from other groups like Centaurs and Lagrangians. There are several objects in the asteroid belt, and they are spread over a large area of space.



Interesting Facts about the Meteorite

Each day, countless tons of space substance is showered on the Earth. The majority of the objects get vaporized in the atmosphere, and some larger pieces fall on the ground. Do you know where the objects actually come from? Well, such objects come from the asteroids. The objects could be different kinds of rocks. These would have existed since the dawn of solar system.

The Meteoroid is those small metallic chunks or rocky materials that come through space. It will be in size of the dust. The small meteoroids are also known as space dust or micrometeoroids. Such fragments could also due to the collisions between the solar system bodies like Mars or the Moon or could be remaining comet debris. In our Earth’s history, several meteorites both small and large in size have reached our Earth surface. Some of the famous meteorites are Hoba, the Fukang, the Williamette Meteorite and the Allende.

The Fukang Meteorite comes under the stony iron meteorite type. It is the best example of pallasite. It has large gem similar to olivine crystals, and the peace of such meteorite is very popular among collectors. It has a good demand among people who collect such meteorites.

The Hoba Meteorite is seen in Africa. It is found in Namibia. The size of the Hoba Meteorite is very large. It will be about sixty tonne rock size. It is impossible to move. The Hoba Meteorite is preserved as a National Memorial in Namibia. The experts say that fell around 80,000 years ago.
