Betelgeuse is a Star in the Orion constellation. It is the ninth brightest star in the night sky, and is classified as a Red Giant. A red giant is a Star nearing the end of its life, Betelgeuse will turn Supernova soon, relatively speaking anyway. To give you an idea of size, if you were to place Betelgeuse in the Sun's position, it would reach further than Jupiter's orbit. It is fairly close only about 600 light-years away, and because it's so big, it burns bright as the second brightest star in the Orion constellation.
It is one really "cool" (actually very hot) star. If you are looking to write a paper or need information for a school project, you picked the right star! It has plenty of unique aspects to explore, and interesting facts to write about...

Listed bellow are a couple of helpful, links to get started! A perfect site to learn about Betelgeuse, extremely well written. Contains a large amount of valuable interesting science facts about the death of large stars specifically Betelgeuse, yet still manages to relay the message clearly so that it makes sense. This site is Very engaging, with great pictures and videos to illustrate. This site also has fascinating facts and quirks to the star that I haven't found on any other site, such as; what Betelgeuse would look like if we could see the entire electromagnetic spectrum.

Good all round source. explains the science behind Betelgeuse's eventual death, and so much more!

Readability: Extremely well written : This is a very good source for papers or assignments, due to the credibility of the site. Also it covers a wide amount of topics giving a couple of the Star's quirks, like the large amount of mass that Betelgeuse has lost in a short amount of time. This site's main point however is how long Betelgeuse will last before going supernova. I would recommend this site for anyone looking to learn more about the star, it is well written and gives a lot of useful and interesting facts.

This site is great for general information, unique aspects of the star, and detailed information on how long the star will last. great page!

Readability: very well written this page has the same sponsor as the one above, and is located on However it covers a different topic, it is mostly dedicated to explaining the backstory and importance of this picture:

Which has a lot of significance. This site also has a very incredible video, that puts everything in perspective. I would again highly recommend this site, even if you don't want to use the information provided, I would encourage you to log on and watch the video. It is short and sweet, and gets the point across.

This site is one I highly recommend checking out. lots of good content, gives great context to this picture and has a great video. Check it out!

Readability: Very well written, does have a couple large science words and acronyms, but they are explained so you can follow along This site is mostly dedicated to the end of Betelgeuse, when the star goes Supernova, but it also covers other topics. Such as the mythology behind Betelgeuse.It also debunks some of the rumors and myths about the Star, and tells what will really happen to the star and the effect it will have right here on earth. Not to mention it has great pictures of the star.

This site tells what will really happen to the star when it goes supernova, and the effect that will have on the earth. Great Page!

Readability: Very well written. Very engaging, and well written. touches on many different aspects of Betelgeuse, but mainly focuses on the supernova aspect of Betelgeuse's life. Also this site talks about the difference between absolute, and apparent magnitude, and what they can be used for. Very interesting and well written.

Good site, great pictures, and awesome content. Check this one out.

Readability: Very well written, and engaging This is directly on the Hubble Site, so very credible. It is less than a page of information, but still worth checking out because it's got good facts. Also explains the apparent lumpiness of the star in photos.

Pretty good, short but still good.

Readability: well written This site is small, only about a page long, but it is a credible source, so if you need an impressive bibliography for a paper or project, it lays out some of the basics of the star and manages to pack in some good facts in a small space.

This site is good for credibility, and is short and simple. If you just want a couple facts and don't want to spend a lot of time looking, this one's good.

Readability: easy read : This link is a small page, covering a couple basic topics about Betelgeuse.. It has a small table giving a couple facts such as 'surface temperature' and 'mass'. The good thing about this page is that once you read about Betelgeuse, it provides much more information about the Orion nebulae. Which is where Betelgeuse is located.

So if you want a simple and short table, and a couple facts about Betelgeuse, and want to know more about the nebulae it is in, this is for you:)
