The Expanse

Filed under: Uncategorized — davidlpf @ 5:30 am

Now that the solar system has been fully colonized tensions a growing between the three main powers. The Earth-Moon which is governed by the UN, Mars which the military runs and the asteroid belt which is dependent on the inner planets. In the first episode it already discusses how the weaker gravity of the asteroids effects the development of the people living there, they are are taller, weaker bones and muscles and weaker lungs because they do not have to fight gravity as much as on the home planet. The asteroids are mined for substances such as water which is needed everywhere in the system. Part of the show takes place on the Canterbury which hauls ice to the port on Ceres the largest asteroid. The shows how the ship has to deal with the changes in force on the crew when the maneuvers or accelerates. When you  accelerate you increase force on you body, this is usually expressed in the terms of g’s. One g is the acceleration you feel from the gravity from the Earth. The human body can survive to up to about 5 gs. In the show the crew is stripped down with some kind of fluid pumped into them. The show demonstrates how ships would more likely to maneuver, instead of a slow curved tun the ships just flops end over end. I hope the show keeps it up for a long while. Me I would avoid any of the factions and find an exploration ship to as far I could go.

Even some stars get left behind

Stars have a predictable way of aging.It is mostly dependent on the mass of the star because this determines how much fuel and by how how much gravity the star can generate to keep it together. For example or star the sun will keep burning hydrogen for the next 4.5 billion years. Then it will get larger and larger staying the same size for shorter and shorter periods. The last stage the sun will throw off the outer layers forming a planetary nebula.

One Class of stars that do not follow their predictable model are stars called blue stragglers. A new study of these stars by Dr. Gosnell my of figured out way these stars do no follow this model. These stars orbit stars that reach the red giant phase of life. The outer layers of the red giants is tenuously   held to the star. The neighboring star sucks these outer layers onto itself gaining mass and fuel leaving the first star a white dwarf. Thus the star increases it mass and burns hotter and bluer. These stars are found in globular clusters. Most of the stars tend to be in the later stages of life while these stars seem be behind in development.

Congrats Dave Lane and Paul Gray

One other thing happened 30 years ago. A supernova was found by a Canadian observatory. The  observatory was the Burke-Gaffney Observatory in Halifax, NS. The discovery was made David Lane now the observatory director and amateur Paul Gray. Paul’s daughter was 10 years old the youngest  person to do so. The coin has a young observer looking through the new Medjuck  telescope Congrats Dave. Paul and the Burke-Gaffney.

Happy 20th anniversary Soho

Filed under: Uncategorized — davidlpf @ 6:56 pm

20 years the Solar and Heliospheric Observatory was launched to the L2 lagrange point which is a point between the Sun and the Earth were the gravity is balanced, actually it orbits around this point because it is an unstable point. Over this time it has help many scientists study the sun such as:

Helioseismology. The sun is not a solid object but a giant ball of plasma. Plasma is a gas that is made up of charged particles, both negatively and positively charge particles. Being a not a solid object there is no real set shape, so the the Sun wobbles and jiggles. With Soho you can measure the wobbles and jiggles, scientist have used these measurements to figure out what the interior of the sun looks like.

CMEs or corona mass ejections. The sun from time to time ejects large amount of plasma from the the outer layer  called the corona. These chunks of  plasma can damage the electronics on satellites and also have downed power lines, so it could disrupt or lives on many levels. With Soho we have been able to predict if and/or when the hit the Earth.
