How to start seeds

Filed under: Uncategorized — davidlpf @ 4:44 am

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.

Shell Elliptical Galaxy has 42 shells

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.
