Anti-Matter

Continuing on the atoms topic, I will be talking about Anti-matter, the opposite of matter. To the untrained eye, anti -matter will look like normal matter, but there are slight differences such as the electric charges which are opposite. So, the proton is negative, the electron is positive (known as a positron) and the nucleus and the neutron have no charge. Anti-matter and matter will obliterate each other on collision.
In recent science, scientists have the ability to make anti- matter in huge machinery and in even more recent science, scientists have captured anti -matter for fifteen minutes, which allowed for deeper understanding of this mysterious type of particle.

Dark Matter

Not much is known about dark matter. Dark matter was discovered 5 years ago and it is practically impossible to detect. Dark matter is nothing like normal matter, for instance, it doesn't give off electromagnetic rays. It was discovered by scientists studying the movement of galaxies and clusters of galaxies.  It forces objects to come together but another force and particle goes against that... but that is something coming tomorrow.

Atoms

This is the starting point for the next four topics. Atoms are matter that make up everything. Atoms cannot be seen by the naked eye, so you need a electron microscope. (Don't get one unless you want your whole neighbour hood to loose all their electricity)  Atoms are simple if you get it. Basically, to make an atom, you need electrons. If you like, think about the atom as a solar system. The sun is the nucleus (centre) and then the protons and neutrons are sun spots, and then then the electrons are planets whizzing around the gravity of the sun or the nucleus and sunspots. The electrical charges of the sub atomic particles are: Protons=positive. nucleus=none. Neutron:none. Electron=negative. The orbit of the electrons or planets are called shells. Well that's it Universe daily fans, Bye.

Solar system:The basics

As i want to make my blog more organised, I'm learning to do a horizontal tabs bar.

This tab is the solar system.

The basics

The solar system has the sun placed slap bang in the centre,the sun produces heat and gravity to keep the 8 planets in orbit. The 8 planets in order of closest to the sun to the farthest are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus (Don't laugh!) and Neptune. You may be wondering why Pluto isn't in there, well, in 2006, the European astronomy association decided that Pluto was one of many Dwarf planets in the solar system. Dwarf planets are small planets that don't have a clear orbit. (meaning there isn't a large amount of material in it's orbit. Between Mars and Jupiter is the asteroid belt, home to the other 3 most famous dwarf planets. They are: Eris, Makemake and Ceres. Another asteroid belt but a smaller one is in Pluto's orbit called the Keiper belt and beyond that, a bigger asteroid belt than the Keiper belt is the Oort cloud. And that is where our solar system is complete.

Galaxy clusters

Galaxy clusters are bassiclly big clumps of galaxies. Each Galaxy cluster has 1,000 galaxies to 1,000,000 (Anything above 1,000,000 is a supercluster) Our galaxy is in the local galactic group galaxy cluster and the virgo supercluster. With the Hubble telescope, sciencetists made a picture of the whole known universe which contained all the galaxy clusters and superclusters. If you look at it, it's like a sponge.

Long time, no fact

Sorry I haven't been able to post for nearly 2 months, it's just because information is running low. Any way, today's topic is active galaxies, to understand this, you must read the galaxies post i did. Basically, active galaxies are highly, radioactive galaxies, most of these are young galaxies, probably 1 billion years old. There are 4 mains types of active galaxies, Seyfert,Quasar (not to be confused with the caravan manufacturer) Blazar (similar to Quasars) and six packs (not to be confused with muscles in the abdomen) Quasars are active galaxies with streams of highly charged sub atomic particles emanating from it's centre. These streams can spread across 2 light years! Seyfert are spiral galaxies that have a highly radioactive centre, scientists think all spiral galaxies are seyferts in one point in there life. Six packs are 6 seyferts near each other and Blazars are not really clear, they are like Quasars but emanating protons.

galaxies

Galaxies are clusters of stars and gas. We are in the galaxy called the Milky way named after a Greek myth in which I cannot remember. The milky way is a spiral type galaxy but some scientists think it's a barred galaxy. The type of  galaxy depends on its shape.The spiral type being a spiral shape, barred galaxies are spiral galaxies but with two arms instead of many. Then there are elliptical galaxies are flat an contain billions of old stars. Lenticular galaxies are like a CD, with a "hole" in the middle and  a circular shape. Finally there are irregular galaxies which come in all shapes and sizes. All galaxies have one thing in common, a super-massive black hole or an ultra-massive black hole in the middle of the galaxy. Most galaxies have older stars near the centre and new stars near the outer regions. Galaxies types also have sub-divisions. For example, one type is spiral Sb. These sub divisions each have a different feature to a spiral type Sc or any other of its type.

Well bloggers, thats it for today, see you!
