Betelguese: The super giant in the neighbourhood

I have written about this huge red giant star before. It is about 600 light years from earth and has a diameter almost as big as the orbit of jupiter.

Now I want to show how this star has been changing over the last few years.

Back in 2012 I was able to take a photo of this star with my camera at a low magnification.

This image is a lower ISO image showing even the less hot parts of the star but no gas around the star.

It showed the star as a red sphere with no gas around the star at all. Although this was as we see our sun, this to me seemed unusual as many stars that I was shooting at this low magnification seemed to have gas could around them.

Then during April 2013 I was able to take a new photo with a magnification of about 3000x which is below.

Clearly this shows a large explosion of gas from the star.

By December 2013 you can see that the gas cloud has moved around the star.

And later again about a month later the gas had become more even around the star.

As time went on into February 2014 we see that this gas eventually stabilised to cover most of the outside of the star .

This demonstration shows that stars are very dynamic energy sources. Betelguese should never be trusted. It is a super giant nearing the end of its life and expected to go super nova at any time. When this happens at only 600 light years away will have an impact on earth by either lighting up the night sky to almost daylight or impacting communications around the world or affecting our outer layers of atmosphere temporarily or permanently.

Betelgeuse the red giant of Orion

Looking up into the night sky, I identified the constellation of Orion. Orion is  depicted in astrology as the mighty hunter.

The stars of orion are particularly interesting, not least a orange looking star at the constellations right arm.

This star is Betelgeuse, a red giant so massive that its diameter is similar to the orbit of Jupiter.

The star is approximately 640 light years away.

REcently I was able to take a photograph of this star with my Fuji camera. By sitting the camera on the tripod and selecting the multi focus option on the camera, I was able to zoom to the maximum the camera would zoom to and take the shot.

My camera has the ability to zoom to 30 times which is equivalent to having a 750mm lens. At this magnification the star was represented as a dot of light on the LCD screen.

Because I have 12 megapixels available to me on the camera, once on my PC iwas able to zoom in a further 800 times without extensive distortion and the photoograph below is the result.

Betelgeuse

As you are able to play around with the amount of light captured by the camera by altering the shutter speed, a faster shutter speed produced the following photo.  This shows that there is zones of higher and lower fusion activity on the surface of the star.

Gallery2020 Publishing’s site is now available from a link at habitatassociation.com.au.

This site is the primary site of the Habitat Association for the Arts and Environment (HAAE).

Gallery2020 Publishing’s continued relationship with HAAE is poised to help widen Gallery2020 Publishing’s exposure to the world by promoting papers and articles by Authors associated with both the Habitat Association and Gallery2020 Publishing.

Gallery2020 Publishing under the auspices of Habitat Association

Galley2020 was first founded in 2001. It was originally a business that provided a service for graphic art. Its services were the provision of business card designs and form design, book covers etcetra.

Later, the owner of the business decided to to write a book. At this time a new name was made for the business. The new name was Gallery2020 Publishing.

After many hours over a 2 year period the book was completed and published under the new publishing business. The name of the book is: ‘Will the Real Melchizedek please step forward’ authored by David Holland in December 2008.

We are hoping that this site will be able to display this book and other works from this author and other authors.

Gallery2020 publishing has decided to join with the Habitat Association for arts and environment and publish in collaboration with this association.

The Association is a non profit group that is interested in promoting writing,  publishing and the arts. As part of its phylosophy  it is interested in writers who wish to write about human environments and social interactions.  This means that it has a strong interest in promoting and mentoring all art forms as well as science as it is applied to human existance.

THe above example of one of Gallery2020 published books is clearly a book based on Biblical text and as such a theological book. Habitat assocation also has interestes in this field as it relates to human social environments.

Gallery2020 is proud to be associated with Habitat Association for Arts and Environment and recommend other publishers, arts organisations and education organisations interested in the human environment or habitat become associated with them.
