SUMMARY

The University of Sydney scientists, led by Professor Bryan Gaensler, have determined that the Milky Way galaxy is twice as wide as previously estimated, measuring approximately 100,000 light years across and 12,000 light years thick. This groundbreaking discovery was made using publicly available data analyzed in a spreadsheet, demonstrating that significant scientific findings can be achieved without expensive equipment. The research team included Dr. Greg Madsen, Dr. Shami Chatterjee, and PhD student Ann Mao.

PREREQUISITES
  • Understanding of basic astrophysics concepts
  • Familiarity with data analysis techniques using spreadsheets
  • Knowledge of astronomical measurements and scales
  • Awareness of online scientific data repositories like arXiv
NEXT STEPS
  • Research the methods used in data analysis for astrophysical measurements
  • Explore the significance of galaxy structure and dimensions in astrophysics
  • Learn about data sources for astronomical research, including arXiv and ADS
  • Investigate other recent discoveries in galaxy research and their implications
USEFUL FOR

Astrophysicists, astronomy enthusiasts, data analysts, and anyone interested in the latest findings regarding galaxy structures and dimensions.

SF
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.

Astronomy news on Phys.org
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
