http://myhero.com/hero.asp?hero=A_M_Ghez_06

OVERVIEW
This page is on a "MyHero" website written by students on some of their heroes in different fields. Under the Science Heroes section this webpage on Andrea Ghez is written to give us a background on what got Andrea Ghez interested in astronomy and some of her big discoveries as of 2006. There are many quotes in this webpage so it gives us a good look on how Andrea Ghez thinks and it backs up a lot of the statements the author makes on her, which is good. The webpage explains some of Andrea's theories with and animation and a picture along with short descriptions of what a black hole is and how she was able to do her research with the world's largest telescope. The author also gives us questions that Andrea Ghez's theories bring up, such as do all galaxies have a black hole at the center of their galaxy? This webpage also gives us a background on her education, some awards she has won, and how she is now a teacher at UCLA along with why she enjoys teaching and some of the strategies she uses to keep her students interested.

ACCURACY:
Although this webpage is old it contains a lot of good information that let us get to know how Andrea Ghez tackles issues in astronomy such as this quote that Andrea asks herself before starting an experiment, " What are the interesting problems of today and where can I make a contribution?" It also gives us a good background on how she got interested in astronomy and some of her background when she was younger including her education, so the age of the webpage is irrelevant there because that will not change. Her theory on the massive blackhole at the center of our galaxy is still accurate and this webpage gives us good information on how she researched that theory and how the telescope she used works.

READABILITY and CLARITY:
This webpage is very easy to read and because the quotes are always relevant to what the author is talking about it makes it clear how Andrea thinks, which I found to be interesting. The author gives us a good definition of what a blackhole is, a picture of the center of our galaxy, and an animation of the stars orbiting around the supermassive black hole. This webpage is written for anyone who wants to better understand who Andrea Ghez is and some of her theories she has made as an astrophysicist and what kinds of questions her theories have brought up. I believe anyone that has any interest in astronomy would enjoy reading this webpage. The author is a good writer and gets to the point with everything she is saying without using fluff, I enjoyed reading this webpage.

EASE OF NAVIGATION:
This webpage is easy to navigate through as it is just one page. If someone wants to know more about a certain topic in the webpage the author also gives us links of where she got her information from so that is helpful for that.

OVERVIEW
This webpage is on the UCLA website and focuses on Andrea Guez as a Professor of Astronomy. It gives us information on where she got her education, including years, schools, and degrees. It also tells us her professional positions she holds and her research interests; such as her study of star formation and her investigation of the supermassive blackhole at the center of our galaxy. The webpage also tells us about the telescope she has used to do her research and how it has the highest spatial resolution obtainable from the ground or even space. It also has questions that her theory of star formation and stars having companions brings up, such as "What effect do the close companion stars have on the formation of planets around these young stars?" Then it goes into depth on how Andrea Ghez was able to make the prediction of a supermassive black hole at the center of our galaxy and how that may mean that all galaxies have one as well. It also contains links of some of Andrea Ghez's publications and some of her past students and group members.

ACCURACY:
The information in this webpage is accurate because it has information including Andrea Ghez's education, how the Keck telescope works, and some of Andrea's research interests which are still relevant today and are still strong theories.

READABILITY and CLARITY:
The target audience for this webpage seems to be people who know a lot about astronomy because the reading is advanced and the way the author describes some of her theories is very technical. However, having said that, I think it gives a decent summary of her research interests and studies.

EASE OF NAVIGATION:
This webpage is easy to navigate through for me, it contains a link to a bio of Andrea Ghez and short pargraphs describing her research interests.

= Galactic Explorer Andrea Ghez = http://www.pbs.org/wgbh/nova/space/andrea-ghez.html

OVERVIEW
This webpage done by NOVA, a prime time science series on American television, contains an interview astrophysicist Andrea Ghez, giving us information on her discoveries, struggles for women in astronomy and some of her mentors from a young age. Andrea Ghez explains the history of the theory that there may be a blackhole at the center of our galaxy, what it means, and what people thought might have been at the center of our galaxy before the theory was brought up, such as dead stars. The webpage also talks about how she has been able to backup her theory that a blackhole exists at the center of our galaxy and why it hasn't sucked up earth yet, which is because we aren't close enough so we just orbit it. The interviewer then asks about her study on star and planet formation and why our solar system only has one star in it. At the end of the interview, the interviewer asks questions on how Andrea Ghez got inspired to study astronomy and how she was able to get mentored as well. The interviewer also goes into the struggles females face as scientists, however, Andrea believes some things have changed for the better and that when girls are encouraged to become scientists it helps out tremendously, which ties into why Andrea Guez loves teaching her freshman astronomy class the most out of them all and that she loves being a role model.

ACCURACY:
Like my first webpage, although this webpage was written in 2006, a lot of the information on it is still reliable and most of what she talks about near the end on what got her interested in astronomy and struggles that females have faced in the field is still accurate. Her information on the blackhole at the center of our galaxy is still accurate from what I have read in more recent articles and because most of the research was done from 1993-2003 the information on this page has remained consistent with today's theory of a blackhole at the center of our galaxy and stars that have companions in different solar systems.

READABILITY and CLARITY:
The audience for this webpage is anyone interested in finding out more about our galaxy, who Andrea Ghez is, her work, and some of the struggles that female face in the sciences. It is easy to read and the way she describes everything, in my opinion, that would be clear for anyone who can read, even at a low grade level. The webpage also has pictures of where the blackhole is in our galaxy and orbits of stars that backup her theory that there is a supermassive blackhole there.

EASE OF NAVIGATION:
This page is easy to navigate through as it just contains questions from the interviewer and then answers from Andrea Ghez, along with pictures relative to the questions that the interviewer is asking. There aren't links in the webpage but the webpage has enough information and is clear enough to where a link is not necessary.

OVERVIEW
This webpage has a short biography on Andrea Ghez discussing where she got her undergraduate and post graduate degree, some of the awards she has won, some of the papers she has published, and some of her talks she has given. It also touches on her theory that there is a supermassive blackhole at the center of our galaxy but doesn't go into depth on explaining it. This biography caps off discussing what Andrea and her team are working on now, which is to test Einstein's theory of relativity and to better understand what roles blackholes play in forming galaxies.

ACCURACY:
The information is all up to date, most of it is just vague descriptions of what some of her research has been and what she is in the process of doing now and the website has been updated this year so it seems reliable. Much of the information is similar to what I have been reading in the other webpages and from what I have seen in her videos but the only problem is there isn't much.

READABILITY and CLARITY:
The audience for this webpage would be anyone who wants to know basic things about Andrea Ghez and what she has done but without going into it to get a good understanding of her research because the reading is short. It is an easy read as it is only five short paragraphs, however having said that it does give you a good amount of information in such a short summary.

EASE OF NAVIGATION:
There isn't a lot of information to find out more on Andrea Ghez, but there is a link that takes you to a website that has good pictures and short videos to give you a better understanding of what this webpage discusses. Therefore, yes it is easy to find out more on the topics discussed and the link is key to making this webpage useful.

=Astronomy: Star tracker =

http://www.nature.com/news/astronomy-star-tracker-1.12622

OVERVIEW
This webpage has many quotes from Andrea Ghez that explain exactly what made her become fascinated with black holes. It also talks about how she went from physics and then later turned to astronomy to get her phd after her epiphany in a observatory dome. It also goes into depth about her research at school on black holes and some of the technology she was able to use to further her research. Towards the end it has the moment where Ghez became sure that there is a black hole at the center of our galaxy because there is so much mass in a very small amount of space towards the center. This webpage also tells us that she is working with a new telescope that is supposed to get 10x more light than the Keck telescope gets so she will better be able to observe our galaxy.

ACCURACY:
This webpage was last updated in 2013, so it is pretty recent and it has reliable sources, such as some of Andrea Ghez's publications so I am fairly certain the information is accurate. It has a lot of good information on her recent and future research she has done. It also gives you a good look at who Andrea is as a person with some of the quotes and technology she has used to research.

READABILITY and CLARITY:
The audience for this is more experienced students who have a decent understanding of not only our universe but some advanced terms as well. It is not that easy to read as most of the information is advanced but if you read it carefully you get a good understanding of Andrea's work in astronomy and her theory on a black hole at the center of the Milky Way.

EASE OF NAVIGATION:
Not only are there links to sources that are used in the article, but this webpage also has related stories that focus on topics discussed in this article.
