In summary, University of Sydney scientists, led by astrophysicist Professor Bryan Gaensler, used data from the internet to determine that the Milky Way is 12,000 light years thick, twice as wide as previously thought. This discovery was made without the use of expensive equipment, and highlights the availability of reliable information online from scientists who publish their data. However, a scientific publication from the team has not been found aside from the university's press release.

It took just a couple of hours using data available on the internet for University of Sydney scientists to discover that the Milky Way is twice as wide as previously thought.


Astrophysicist Professor Bryan Gaensler led a team that has found that our galaxy - a flattened spiral about 100,000 light years across - is 12,000 light years thick, not the 6,000 light years that had been previously thought.


Proving not all science requires big, expensive apparatus, Professor Gaensler and colleagues, Dr Greg Madsen, Dr Shami Chatterjee and PhD student Ann Mao, downloaded data from the internet and analysed it in a spreadsheet.

Sounds all most to simple, is there that much reliable info on the web?

lots of scientists will put the data they produced online. You canf find links in their articles
at http://adswww.harvard.edu/index.html or arxiv.
I can't find a scientific publication by those authors about this however, aside from the
sidney university press release
 

Related to The Milky Way is twice the size we thought it was

What evidence supports the claim that the Milky Way is twice the size we thought it was?

Recent observations from the European Space Agency's Gaia satellite have provided accurate measurements of the positions and movements of over 1 billion stars in the Milky Way. These data show that the outer reaches of the galaxy extend much farther than previously believed, indicating that the Milky Way is twice as wide as previously thought.

What implications does this discovery have for our understanding of the Milky Way?

This discovery challenges previous models and theories about the structure and evolution of the Milky Way. It suggests that our galaxy is much larger and more complex than we previously thought, and opens up new avenues for research and exploration.

How does this new measurement affect our understanding of the solar system?

The new measurement of the Milky Way's size does not directly impact our understanding of the solar system, as our solar system is just a small part of the galaxy. However, it does provide a more accurate context for our place in the larger galactic neighborhood.

Will this discovery change our understanding of the universe as a whole?

This discovery does not significantly alter our understanding of the universe as a whole. However, it does provide new insights into the structure and dynamics of our own galaxy, which can contribute to our overall understanding of the universe.

What further research is needed to confirm and expand upon this discovery?

More observations and analysis are needed to confirm and expand upon this discovery. This could involve using additional telescopes and satellites to study different parts of the galaxy, as well as incorporating other types of data and simulations to better understand the Milky Way's size and structure.
