New results from the Sloan Digital Sky Survey
From the second press conference at the AAS meeting today, results from the Sloan Digital Sky Survey, which has been surveying the sky in incredible detail over the past eleven years:
- The largest digital color image of the heavens, covering one third of the sky, imaging a half a billion stars and galaxies. Despite looking the sky in wide-field view, the data also has incredible close-up detail. This has and will continue to provide astronomers a precise baseline reference for future research.
- A 3D reconstruction of the local galactic neighborhood, showing the three dimensional position of the visible galaxies within a billion light years. They plan to use the new Sloan color image above to further extend this 3D reconstruction out to seven billion light years.
- The largest map of the Milky Way’s outer regions, showing the streams of stars captured from other galaxies, absorbed in the past galactic mergers that formed the Milky Way.
All this data will be available for anyone to dig around in.
The support of my readers through the years has given me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Four years ago, just before the 2020 election I wrote that Joe Biden's mental health was suspect. Only in this year has the propaganda mainstream media decided to recognize that basic fact.
Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Even today NASA and Congress refuse to recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
