Some interesting developments concerning the Cosmic Background Radiation
are starting to show up.http://arstechnica.com/science/2013/03/ ... ackground/
Most people would know that a NASA satellite named COBE produced a detailed map of the radiation a while back.
What you mightn't know is that prior to COBE the University of Berkeley, in partnership with the Japanese Space Agency launched two probes to do much the same thing (on a much smaller scale). Paul Richards and Andrew Lange were the chief researchers. The reason that there were two probes was because the data the first probe collected didn't match the expected result completely and they wanted to verify their results before COBE launched.
This is what their first probe found:
Note the two dots lying above the main plot. It was thought that these were errors at the time.
This is what COBE found:
Since then we have had another satellite mapping the Cosmic Background Radiation in greater detail (the WMAP Probe
) as well as several ground based telescopes making observations.
This is what they have found (so far, lots more data released later this month):
Just goes to show that the Berkeley University results were not as wrong as everyone thought that they were after all, we just needed more data to make sense of what we were seeing. This is why good science is always built on lots of experimental data.
I'm uploading a video (yes, it's from my beloved The Astronomers series!
apoppin will just love me!
) that will show Berkeley vs COBE, will post the link when it is complete. Some people may like to mock older theories, but it is amazing how well the content presented in The Astronomers has stood the test of time!
