"Exoplanet Building Blocks Found around White Dwarfs"
Overview: Excerpts from John Matson podcast

"Astronomers identified the silicon-rich rocky material by [[#|training]] the Hubble Space Telescope on the nearby Hyades star cluster. Finding rocky material means the stars once had the raw ingredients to make exoplanets—although almost no known planets orbit stars inside of clusters." ... "The discovery of planetary material thus raises more questions. Are star clusters indeed inhospitable to planets? Or are planets around stars in clusters for some reason just harder to spot? In the Hyades cluster, at least, it looks like there may be planets that have so far escaped our notice."

ACCURACY:
The site is information regarding a mission proposed to explore [[#|Extrasolar Planets]]. The mission aims at getting more information on the conditions required for these planets to form and the possibility of life on them.
READABILITY and CLARITY:
The readability score for this site received a 42, the site is targeting specifically scientists because they want to share the knowledge they plan to go explore and bring back. The score for readability is probably not so high to reflect their audience because they market to all kinds of scientists, not all scientists can read at a 70 on this scale so they are attempting to keep it clear enough to understand for everyone.

‍EASE OF NAVIGATION:
The page is easy to navigate at the top of the page are buttons to different topics. The layout is not so great but that is just a technical thing that can be fixed, other than that it is easy to access the information you are looking for once you get to the site.

ACCURACY:
Information from this site serves as a research and educational virtual laboratory for studies of the habitability of Earth, the Solar System, and extrasolar planets. This website is essentially a directory of potentially habitable exoplanets that educators, astronomers, and everyday people may be interested in discovering more about.The website gives a lot of information for each of the planets it focuses on.

READABILITY and CLARITY:
The site contains information other than that of exoplanets but you are sure to find what it is your looking for when you visit the site because on the homepage in very bold print is a picture link to "Habitable Exoplanets Catalog" by seeing this easily in plain view it makes the process of getting to where your looking for much easier. The readability grade the website received was a 34.9. The webpage is a catalog for anyone who is interested in habitable planets beyond our Earth so the creators of the webpage must have took that into consideration they wanted to make the website seem clear enough for a wide range of people to understand while remaining scholarly. The site appears to be credible because they are not afraid to share the work put into getting their results.

ACCURACY:
This site you can tell is well put together, Seager dedicated a lot of time with an entire team of researchers to solely focus on exoplanets and their characteristics. Many of the points she discusses are backed up with graphs to give a visual representation of what it is she is talking about. The way the page is set up gives you background on what exoplanets are and then it is categorized into subsections with actual paper write ups for readers to access to see raw data.
READABILITY and CLARITY:
The audience is most likely college aged to professional individuals because it can be found on MIT’S website, most college kids are not browsing there. The readability for a passage on the site came out to 29.3. Sometimes when you are dealing with complex information such as planets and science related topics it’s best to keep the language simple even if your audience is far more advanced and I believe this is what Seager and her team did.
‍EASE OF NAVIGATION:
The page is very easy to navigate and find what it is your looking for. The page is organized in categories such as Exoplanet Atmosphere, Exoplanet Interior Composition, and Exoplanet Biosignatures. Under these categories you can find information about that particular topic with links to papers written by Seager and her team about the topic as well.

ACCURACY:
The Planet Quest [[#|website]] consists of many pictures and in depth explanations on five different techniques of finding an exoplanet. It is very reliable, and updated quite often. The homepage of the website lets you know right away exactly how many exoplanets have been discovered, including the ones that are still candidates and the ones that are already confirmed. The website has many informative, interesting, yet simple multimedia videos explaining the different methods of finding planets. These methods include radial velocity, astrometry, transit method, and optical detection. The website provides many links pertaining to exoplanets, even the exoplanet missions, including the Kepler Mission. The most interesting feature of the website was the 3D New Worlds Atlas which explored the exoplanet neighborhood through an Adobe link.
READABILITY and CLARITY:
The information that the [[#|website]] consists is very accurate and is generated by credible sources. The website is somewhat easy to navigate. Some of the tabs are self-explanatory but there are are some information that is a little harder to find. The audience of the content is students and professionals who wish to learn techniques of how to locate an exoplanet. The readability score of the content is about 57 which is a little lower than the average. However, it is appropriate for the target audience of the website.
EASE OF NAVIGATION:
The website is fairly easy to Navigate you go to the homepage and in a way have to dig through to arrive at the information you would find useful to the subject matter you are interested in looking at. Unlike some of the other sites say for Exoplanets it isn’t directly laid out in front of you because they focus on a wide range of topics.

ACCURACY:
The [[#|website]] has a lot of fun and interesting articles to read. It is sponsored by the NASA astrobiology program, and is a web-based publication that offers daily news and features about the study of life beyond Earth. One interesting article in this website is about the "Superior Super Earths", or in other words planets like Earth that range up to 2 to 10 Earth masses which could be superior to Earth when it comes to sustaining life. This addresses the question as to why we haven't been visited by aliens. There are super sized planets that could be more interesting than the very Earth we live on. This is called the 'Fermi Paradox'. The website is updated quite often with new articles on different subjects, including exoplanets. Almost every day there is a new article that is added to the database. There is a multimedia link that has a new image everyday which provides hundreds of new pictures. Under the "Hot Topics" link located in the homepage, there is a "Deep Space" category which provides many articles about exoplanets and all the new amazing facts recently discovered.
READABILITY and CLARITY:
The audience of the [[#|website]] also seems to be students. The readability score of the content is 58 which is very close to the average making it appropriate for the target audience.
‍EASE OF NAVIGATION:
The [[#|website]] provides accurate information that can be supported by other data. The articles in the website can be sorted by the month and year to narrow down the search which seems to be a very helpful tool thus making the website very easy to navigate.

SuperWASP is a United Kingdom's extra-solar detection program. This consists of two robotic observatories that operate continuously all year round. The website itself provides information about the observatories. It also provides updates of any latest discoveries that were made by the observatories. Under the category "Wasp Planets", there is a web page that presents different information about exoplanets. Just like one of the website provided above, it also techniques of how to detect an exoplanet. These techniques are pulsar timing, radial-velocity, astrometry, gravitational lensing and photometry.

The content of the [[#|website]] is very accurate especially compared to the information that are also listed on other credible sources. The website itself is easy to navigate but it is not very easy to find where to get more information about exoplanets. The audience of the content seems to be those who are pursuing to detect an exoplanet themselves. The readability score is 40 which is definitely lower than the average but it still seems to be accurate for the target audience.



European Southern Observatory

Last Updated: November 2, 2011

eso0603a.jpg

The European Southern Observatory has observatories that are equipped with unique instruments for finding, studying and monitoring exoplanets. They were able to spot faint glows outside of the Solar System taking the first ever picture of an exoplanet. Their astronomers use HARPS, the High Accuracy Radial velocity Planet Searcher, to discover exoplanets orbiting a nearby star. They discovered many different sizes and masses of planets. The smallest ever discovered is a planet that has about the same mass as Earth.

The contents of the [[#|website]] are accurate especially comparing to the information found on other website as well. There are credible sources for the information that was provided. The website is easy to navigate but it's not easy to locate the link for exoplanets from the homepage. However, after clicking the link "Science with ESO Telescopes", the exoplanets well then be very easy to be located. The readability score is 39 which is very low compared to the average score which means the it might be a bit hard for others to understand the contents.


BBC
Extrasolar Planets

exoplanetbbc.jpg

BBC is British public service broadcaster. The BBC website has a special page that includes information about exoplanets. It gives updates regarding what is currently going on with the exoplanets research. There are TV clips and radio programs shown on the website that shows programmers discussing exoplanets. The contents of the clips shown vary from the first exoplanet found to how to hunt an exoplanet. The page also mentions what objects were used to make the observations included in the clips and who observed them.

The contents of of the clips are very accurate and have credible sources. However, the included definition of what is an exoplanet was just generated from Wikipedia, which might not be the most credible source for the information. The website itself is easy to navigate but it is definitely hard to find where the exoplanets page is. It can be found under science, then space, then universe, then sights and finally, exoplanets. The easiest to get to this is to look up exoplanets in the search bar. The readability score of the contents is 45.5 which is lower than the average but still seems to be higher than the other websites about exoplanets.

The AstroBiology website describes that astronomers have discovered over hundreds of Jupiter-like planets in our galaxy. On the other hand, they've found a handful of Earth-like planets as well that might possibly contain life on rocky planets with liquid water. The website provides information of how our planet's interior works, such as the moving Tectonic Plates in the crust, making it possible for life to thrive on it. The page even describes how other Earth-like planets may be different in climax, size, and gravity. According to the page, astronomers are actually working on a mission involving the Kepler Space Telescope, that was launched this year, to travel great distances to discover new Earth-like planets.

The contents on the page are accurate but it provides a very little amount of sources to support the facts given. There are some credible sources provided on the website. The website is easy to navigate but the article that involves exoplanets is not easy to find. It is under Hot Topics, then Deep Space, then Cosmic Evolution, and finally Superior Super Earths. The audience of the page are people that are interested and curious about finding other planets very similar to Earth and possibly discovering life on them.

The website is part of Zooniverse where the public can take part in actual science projects. It is not an informational website that shows facts about exoplanets. Instead, it's a website where anyone can help participate in researching exoplanets. The site gives step by step instructions on how to locate different planets around us. A good example is the image above. To find new possible planets you have to indicate sudden drops in the collection of dots.

The page does not provide too much information too learn about exoplanets, it is basically a tool to use. However, it does provide some information provided by Kepler Public Data which is a credible source. The website is extremely easy to navigate especially because it provides step by step on how to interact with the images on the page. There are many links you can get access to by clicking on the tabs at the top. The audience is any individuals who wants to participate in actual science projects that is in search of exoplanets.
