If the distribution of those nine satellite galaxies across the entire Milky Way is similar to what was found in the footprint captured by the HSC-SSP, the research team calculates that there actually may be closer to 500 satellite galaxies
WTF? I was thinking there were around a dozen or so.
Ethan Seigel never does "clickbait’ articles. He does 100% educational articles. I actually didn’t know more than half of these things. Who the hell knew that Earth does not have the most water in the solar system?
We can indirectly detect dark matter thru gravitational lensing. That is how NASA created this map showing the actual locations of dark matter in tinted blue.
“Whatever is causing gravity to work differently at a galaxy scale than at a solar system scale”.
Nothing is. Gravity works the same. We don’t just infer dark matter from gravity fields. We can detect and map the exact locations of dark matter thru gravitational lensing.
