Jenna Bell’s Journey to Black Hole!

Filed under: Uncategorized — jennabell at 4:06 pm on Wednesday, June 20, 2012

1. The object in the sky that contains stellar black holes is Cygnus X-1.

2. The object in the sky that contains Super Massive black holes is Cygnus A.


  • Moon
  • 240,000 Miles
  • The moon is earths companion, orbiting around it every six months. It has different Phases but never changes face, leaving us to only see the light side of the moon not the dark.
  • Sun
  • 93 Miles
  • The sun is the closets star, and the center of our universe.
  • Milky Way Center
  • 28,000 Light Years
  • The Milky Way is the Hear of the Universe.

Jenna Bell’s Lifecycle of a star!

1. A protostar is an early part in the evolution of a star. After the collapse of the gas cloud (where it is formed), but first before it is  sufficient contraction has happen to permit the entering of nuclear reactions at its core.

2. The Nebula is made up of  hydrogen (97%) and helium (3%).

3. A Nebula is made into a protostar when the gas cloud collaspses.

4. There must be complete balance between gravity pulling atoms toward the center and gas pressure pushing heat and light away from the center to stay as a star.This is called equilibrium, and is verry hard to form.

5. Process:

1.Gravity pulls gas and dust inward toward the core

2. Inside the core, temperature increases as gas atom collisions increase.

3. Density of the core increases as more atoms try to share the same space.

4. Gas pressure increases as atomic collisions and density (atoms/space) increase.

5. The Protostar’s gas pressure RESISTS the collapse of the Nebula.

6.  When gas pressure = gravity, the protostar has reached the equilibrium and stops.


1. The two options for a protostar are:

  • Where the temperature is critical in the
    core of a protostar is not reached, it ends up a brown dwarf. This dwarf never makes “star status.”
  • When the critical temperature in the core of a protostaris reached, then nuclear fusion begins. We identify the birth of a star as the moment that it begins fusing hydrogen in the core into helium.

2.  Nuclear Fusion is the reaction in which two nuclei combine to form a nucleus with the release of energy.

3. A star is a really hot ball of gas, with hydrogen fusing into helium at its core.

4. A star spends most of its life as fusing hydrogen.

5. Because it needs to make up for the lost of heat and light over the billions of years.

6. Temperature is what rises.


1. Small: 15, Low: 54, Medium: 43, Massive: 31.

2. Stars die of old Age, Bigger stars die faster than smaller stars because the bigger ones burn faster than the smaller ones.

3. Protostar – Fusion ignition – Main Sequence – Red Giant/Super Giant – White Dwarf/Black Hole.

1.  Bow Shock is where the heliosphere, forms this magnetic bubble that surrounds our planets, it shovesits way through the interstellar medium, and then the gas floats between the stars.

2. The Heliosphere is kind of like a bubble around our solar system, it protecdts us from intersteller space.

3. The Heliosphere escapes from the Sun at a speed of 670,000 to 1.7 million mph.

4. The true edge of the Solar System is where the solar wind slams into this interstellar gas, far beyond the distance to Pluto.

5. The IBEX stands for Intersellar Boundary Explorer.

6. The IBEX  sees the edge of an invisible bubble that’s billions of miles away. Neutral atoms can cross magnetic field lines, entering in to the Sun’s magnetic bubble from interstellar space. Once these ENA’s reach Earth, the IBEX records them and the directions they came from.

7. ENA’s stands for Energetic neutral atoms. They are created when charged particles in the solar wind interact with atoms coming from beyond the solar system.

8. The ENA’s helps imagine what the magnetic bubble that surrounds the solar system looks like.

9. The IBEX actually measure the data of the ENA’s by recording the ENA’s when they reach earth and also the directions they  came from.

10. The Sun is moving through the intersteller gas at a speed of 52,000 miles (84,000 km) per hour.

11. It is 12% slower than the original prediction.

12. The Sun is creating a ”bow wave”which is a small section that is slightly increased density (more like a fast-moving boat than a fighter jet).

13. The Voyager 1 and 2 have crossed the heliosphere’s termination shock.

14. The heliopause is the bounary of the heliosphere.

15. The best example of where bow shock occurs on a start is Mira.

16. The star is moving 130 km/s (almost 300,000 mph) and leaves a trail of ionized gas 13 light-years long.

17. The GLAX stands for the Galaxy Evolution Explorer, and messures the star speed by taking pictures.

      Astrology Aries March 21 – April 19

      Aries Strength Keywords:

      - Independent
      - Generous
      - Optimistic
      - Enthusiastic
      - Courageous

      Aries Weakness Keywords:

      - Moody
      - Short tempered
      - Self-involved
      - Impulsive
      - Impatient

      Aries and Independence:

      Aries personalities are independent. Being the first of the zodiac signs, they venture out and are go-getters, often leading the way. Their upbeat and magnetic personality often entices others to follow their lead because Aries personalities bring excitement into others lives.

      Aries and Friendship:

      Aries are good friends, they always look out for their friends with caring and generosity and will protect them should the need arise and encourage them with their natural optimism. If confronted, Aries can turn to be quite childish, they will fight back with their agressive nature and are known to have temper tantrums should they not get their way.

      Aries and Business:

      Aries are activists. If a business idea comes their way, they tend to plunge right in. Aries are more then willing to take a gamble and follow their dreams and goals. However, if success is not immediate, they tend to lose interest and give up easily. Aries are notorious for not finishing what they have begun. This is due to the low tolerance for boredom and lack of patience. If the excitement is gone from their business idea, they go off and search for it elsewhere.

      Aries Temperament:

      Independence is key to Aries astrology, they do not like to take orders from others and enjoy getting their way. They can get childish or moody should they be given orders that they do not like. Aries easily take offense to comments made. Aries are self-involved and can be self-centered, if they do not pay attention to the feelings of others, Aries can easily become spoiled and resented by others. In order to get their way, Aries will tell a lie if it seems advantageous to do so. They are however, not very good liars and other people can usually see through them.

      Aries Deep Inside:

      Underneath the strong, independent surface may lie insecurity. This is due to the intense drive to succeed and Aries put too much pressure on themselves, thus resulting in self-doubt however, the natural optimism and enthusiasm overtakes this and the underlying insecurity may never be known to others.

      Aries in a Nutshell:

      Aries is the first of the zodiac signs. Aries is the sign of the self, people born under this sign strongly project their personalities onto others and can be very self-oriented. Aries tend to venture out into the world and leave impressions on others that they are exciting, vibrant and talkative. Aries tend to live adventurous lives and like to be the center of attention, but rightly so since they are natural, confident leaders. Aries are enthusiastic about their goals and enjoy the thrill of the hunt, “wanting is always better then getting” is a good way to sum it up. Aries are very impulsive and usually do not think before they act – or speak. Too often Aries will say whatever pops into their head and usually end up regretting it later!

The planet that rules aries is Mars and the Sun.

  • Q: What do you personally think about Astrology?  Does your sign’s description match your personality?  Describe what parts do and do not match your own personality. Look at the sign that is closest to your zodiac sign.  For example if you are a Leo but 10 days away from a Virgo, then look up Virgo’s description.  Do you have any traits that are close to that sign?
  • A: I think that Astology is awesome and I love learning about it! Its helps us keep track of time and oh so much more. The sign discription does match my personality! I am very stubborn when i get my mind set on something, I also feel for people to a point of were I have to generously give my time. That’s why I love helping people, that’s why I love being need/wanted. I’m super Enthusiastic! I have grown up acting as a kid, doing cheer leading, and that’s whats helped me know how to put on a good face for people! And also the reason why I dress up for every spirit day! Its just something that I love to do. I am independent, even though I love help from others, I like to be in charge. I like figuring out things and doing it my way. I also am very courageous even though at times I know I can get super nervous, I still push my self to be strong  because I don’t like being or feeling week. I like being the first person to do something or try something. I love the feeling of it all, being the first to experience something… weather its good or bad. This makes it so that i can be an example to others and help lead them the right way. I also have to be very courageous because of my religion which makes me stick out like a swore thumb. I have to keep my standards no matter how high they get because everyone is just waiting for me to mess up.  I also have to stand for whats right, no matter how many people think that what they believe to know is true is right, is not (to me). And last but not least I am very Optimistic, I hope for the better, I wish for wish hoping that they will come true. I believe in a ending that doesn’t really end. That when we die its only our earthly bodies and not our souls. That families can live together forever. On the flip side I am short tempered when I’m sick, tired, or having a bad day. I’m not totally involved with myself, I do like attention but who doesn’t? I am impulsive and impatient and those work hand in hand. It’s because I like to get things don’t and not wait for people to just figure it out. And lastly I am moody because well it just all depends on the situation and such.

  1. Washington state University
  2. 20 members Lead by Dirk Schulze-Makuch
  3. BOLD- Biological Oxidant and Life Detection
  4. The mission will send 6 triangle probes wieghing in as 130 to parachute down. Then penitrate the surface about 1 foot to get a soil sample, that will get tested 12 times and all of the data will be sent to a transmiting orbitor above.
  5. Hydrogen peroxid, because the microbial organisms might being using it and water as their inside fluid. If correct this will match to the same findings with the Viking Mars Landers.
  6. There are 6 probes each with a 98% chance of landing correctly. Only two of them will have different jobs:
  • The microscope will find similar shapes that are known as terrestrial microfossils.
  • The instrument will find single long molecules that are like the long nucleic acids created by life on earth.

7. I think that if the mission goes as planned then yes there may just have been life on mars, but I do not think that its the life that every one is thinking of. I think the life that would be found would have to look under a microscope to see it, not like an alien will green skin and looks like ET.
