I know there are plenty of places that explain how to do this but I will do it as well.
First the step is to get some potting soil, some pots and of course seeds. To start seeds the best thing to get is a set that comes with a tray with a bunch of small plastic or sometimes with disks that if you water them become pots. Also, will need some potting soil almost any will do. Then when you get home and it is warm enough to start them you should fill them about 75-80 % to the top like these.
The next step is to put a few seeds in each pot. Some big seeds like squash and pumpkins put about two seeds in each pot. Some of the smaller seeds you should put in few more because some the seeds wont germinate and later they can be seperated and put into individual pots.
After that is done cover the seeds with more potting soil.
After a couple weeks you should get a tray of plants that kind of look like this.
Place the the tray in a warm spot, does not have to in the light for until the come out of soil. Then place in a window, the best spot would have sun all day. Water as soon as you are done planting, the best way is to pour the water into the tray. The soil will absorb the water as it needs it, also it the seeds will not be be disturbed. Most plants have what referred to as seed leaves. These are actually inside the seed also are do not resemble the leaves that will the plant will eventually have. Plants of the same family such as peppers and tomatoes will have the same shape of seed leaves.
What are Shell Elliptical Galaxies
Galaxies come in three main types. One type are the irregular galaxies.these a giant blobs of stars and typical small galaxies. The nest are the spiral galaxies these have a central area with arms spiraling outward, the most famous of these is the Milky Way(us). The next type of galaxy are the elliptical galaxies, if you take a cross section it will look like an ellipse. The largest types of these lay in the middle large of clusters of galaxies and are made from the combination of smaller spiral galaxies. Some these galaxies appear to have shells around them. There are in three dimensions but do not cover the entire galaxy and are bluer than the galaxy they surround which means that they contain a lot of younger stars.
A study of galaxy NGC 3923 using the MegaCam on the CFH telescope in Hawaii has shown this galaxy has 42 shells around it. The team was looking for a shell predicted by MOND but the shell was not there. The team is saying they did not find the shell because the previous observations were in error.
One of the first steps in finding life outside of the solar system is to find a planet that life can call home. There have about 2000 planets found around other stars, some these are much larger of Jupiter and a few are the size asteroids. Location is also important because life on Earth needs liquid water, so astronomers assume the best places for life is were liquid water would exist. These areas around a star are called habitable zones. To find these planets there are two methods one is staring at a star hoping a planet passes in front of it, the Kepler space telescope was designed just to do this. The other method is the Doppler method, when a star is pulled away from you the light becomes redder and when the star approaches you the light appears bluer.
A new tool for finding these planets has been contracted by NASA to go on the WIYN 3.5 m telescope at Kitt Peak in Arizona. The NEID spectrograph, the name derive from the Tohona O’ordham tribes word for to visualize or discover, Kitt Peak resides on their land. The spectrograph was designed and being built by Penn State university.
For the first time astronomers have seen a star explode or go supernova. There are two different types of supernova. The first type is when material from the atmosphere of one star is drawn onto the surface of an orbit white Dwarf and after too much material lands on its surface it explodes. The second type is when at the end of a large stars life and runs out of material to burn it explodes.The stars that were caught in this very rapid process were 300 times the size of the sun at a distance of 700 million light years away and the other was 500 times the sun and 1.2 billion light years away. They were caught by the Kepler Space telescope, it was designed to look at a small patch of sky to see planets moving in front of the stars. Peter Garnavich and his team took advantage of this constant staring at the same patch of sky. In the field of view there were 500 galaxies with 50 trillion stars in them.
Where did all that gold that all those gold miners come from. The lightest of elements come were formed during the Big Bang. The elements up to iron were made in the cores of stars. Even the most massive of stars so not have enough gravitational energy to squeeze more protons into the nucleus of the atom to create more massive elements. These heavier atoms are created by neutron capture, after the nucleus absorbs the neutron it decays into a proton, electron/positron and a neutrino.One way this could happen is the supernova explosion of the larger stars the neutron capture. Another way is when two neutron stars collide. Neutron stars are the cores of much larger stars that lost there outer atmospheres after burning their nuclear fuel and are mostly made of neutrons, The evidence supporting this has come from an ancient faint galaxy orbiting our own called Reticulum II.
For over 20 years people have discovering fully formed planets around other stars. Now in a proto-planetary disk around star HL tau some 450 lightyears away and only 1 million years old, there has been found what maybe the early stages of planetary formation. The Karl G. Jansky VLA telescope has found a 3 to 8 Earth mass clump This was done in the radio part of the electromagnetic spectrum. because shorter wavelengths like visible light is scattered by the dust in this giant dust cloud and radio waves just goes around the dust. This might help in the understanding how planets are formed and how solar systems evolve over time.
According from Einsteins theory General theory of relativity space and time are combined into space time. It consists of three spatial dimensions and time. One way to imagine this to visualize a fabric stretched out tight. When something massive is place in this fabric it creates a well or depression in the fabric. The more massive the object in this fabric the deeper and steeper the well will be. if an object is orbiting another object the system will send out waves in this fabric. The more massive these two objects are the larger the waves will be. Such as two black holes colliding, in this case each about 30 solar masses, with diameters with a diameter about 150 km. this collision took place about 1.3 billion years ago.
This collision was detected by two observatories one in Louisiana, and Washington state. In these devices, light is split into two beams that travel at 90 degrees to each other and then the light is reflected back to a detector. If there is a difference in how much time the light, it means the distance the light traveled is different so something stretched the tube the light is in. The difference in length was 1/1000 the diameter of an atom over 4 km so the signal is very weak, and there are many ways of trying to get rid of envromental noise.
I really liked the original series, well at least the first couple of series. The quality fall off so did their audience. They brought back the series in a mini series called Heroes Reborn. In the mini series they have to save the world from a massive coronal mass ejection. First off there are such things but it is not they portray it also the Earth will be destroyed this time because the Earth’s magnetic field will go down.
Coronal mass ejections happen when the sun ejects part of the outer layers the sun. The sun does from time to to time, the times go on a 11 year cycle. When it is part of the sun it gets energy from the core of the sun. This material is electrical neutral most made from hydrogen that got excited enough so that the elections and protons separate. In the show the show it as a ribbon that stays together as it travels through space. This would not happen there is nothing to keep it together, the particles would go in all different directions, also they energy the particle would lose energy as they travel to the Earth so we wouldn’t even see the ejections.
The other part of the event they must avert is that the Earths magnetic field is about to fail. The Earths magnetic field will decrease then reverse on the time scale from a hundred thousand years to a million years. The magnetic field directs the particles to the poles and as the concentrate they start to interact with the molecules in the atmosphere. As the particles from the sun interact with the molecules and atoms in the atmosphere, the elections in the molecules and atoms get excited and then go back to their ground state. When that happens the atoms and molecules emit light and we call these the northern lights. The main problem these particles would do to the human race if the magnetic field was down would knock out electronic devices. There would be no world wide blaze, a better choice would of been an asteroid hitting the world.
I liked the original idea of heroes. That was what if regular people suddenly got superhuman powers, would who use them to help others, would you hide from the masses or would use the powers for your own good. Maybe they come up with a better story, I rich TV personality who somehow is leading in the polls to become President.
Last night the X-files started a six part mini-series. The entire series was built on the premise that aliens exist and they have been to Earth also they are in conspiracy with the major governments of the world to engineer humans with their DNA. In this new edition they are going in a slightly different direction trying to work in some of the new conspiracy that have come up over the last fourteen years.
There probably life out there in the universe, given the number of planets we have found there is plenty of opportunity for life. Most of the life is probably micro organisms, intelligent life is probably more rare, maybe we might find it here. Due to the distances between stars we more than likely have not been visited by aliens.
Conspiracies are generally when groups of people get together to do something unlawful in secret. The biggest conspiracy theories were that the moon landings in the sixties and seventies were faked, another on is that the JFK assassination was done by the some other than Oswald. Some of these conspiracies probably come from shock that someone could kill a president all by himself without help or that the achievement that goes against there views on the world or the universe. Most of them are just seeing connections that do not exist just prove their theory right.
The reason I like series like X-files, Dr.Who, Star Trek and others is that show the possibilities of what is possible and the consequences of your the actions. The problem is that some people can not tell the difference between the fantasy and reality.
